Salary sacrifice is an arrangement where an employee gives up part of their gross salary in return for a non-cash benefit. Salary sacrifice reduces the pay subject to employer NI and income tax, making salary sacrifice a tax-efficient option for both employers and employees. Common types of salary sacrifice schemes include pension contributions, cycle to work, and electric car leases. Employers save 15% of the sacrificed amount in employer NI, while employees save on their own NI and income tax. Salary sacrifice is only viable for employees whose pay remains above the National Minimum Wage after the sacrifice, and salary sacrifice requires employer agreement and contract modification.

Employers set up salary sacrifice correctly by formalizing the arrangement in writing and amending the employment contract before reducing pay. Payroll must process the reduced gross salary, ensuring compliance with the minimum wage floor. Salary sacrifice can be combined with the Employment Allowance, which further reduces the employer NI bill. The salary sacrifice savings fit within the wider context of total employment costs, including salary, employer NI, and pension contributions. To keep estimates accurate for 2026/27, employers should use current-year figures, considering the 15% employer NI rate and secondary threshold.

What is the salary sacrifice employer NI saving calculator?

The salary sacrifice employer NI saving calculator is an online tool that calculates the employer National Insurance savings when part of an employee's gross salary is exchanged for a benefit. The calculator requires inputs such as the gross annual salary, the sacrifice amount, and the benefit type, which could be a pension, cycle to work, or electric car arrangement. The calculator outputs the annual employer National Insurance saving, calculated at a 15% rate on the sacrificed pay.

The salary sacrifice employer NI saving calculator assesses how much an employer saves in National Insurance Contributions (NICs) when implementing a salary sacrifice scheme. The calculator computes the reduction in NICs due to the adjustment in gross salary once the user enters the salary and sacrifice details. The NIC saving helps businesses reduce payroll expenses while offering benefits to employees. The accuracy of the calculator depends on the correct input of salary figures and the applicable tax year, ensuring that the savings estimate reflects the current financial regulations.

The salary sacrifice employer NI saving calculator helps employers understand the financial implications of offering salary sacrifice schemes. The calculator provides a clear estimation of savings, supporting financial planning and decision-making. Employers use the calculator results to determine the feasibility and benefits of implementing such schemes, ensuring compliance with tax laws and reducing payroll costs.

How does the salary sacrifice calculator work?

The salary sacrifice calculator reduces the salary subject to employer National Insurance (NI) by the sacrifice amount, then applies the 15% employer NI rate to the difference. The salary sacrifice calculator first takes the gross salary and subtracts the sacrificed amount. The salary sacrifice calculator then compares the employer NI contributions before and after the salary sacrifice to determine the savings. The saving equals the sacrificed amount multiplied by the 15% employer NI rate, assuming the sacrificed pay is above the secondary threshold and the benefit qualifies for salary sacrifice treatment.

The salary sacrifice calculation method lets employers project their savings. For example, when an employee earning £40,000 sacrifices £5,000 for pension contributions, the calculator first computes the employer NI on £40,000 and then recalculates the employer NI on the reduced salary of £35,000. The difference between the two figures represents the employer's saving, which stays consistent across all qualifying salary sacrifice arrangements.

How does the calculator handle different sacrifice schemes?

The salary sacrifice employer NI saving calculator applies a consistent 15% employer National Insurance saving to all qualifying schemes. The calculator adjusts for benefits that are exempt from National Insurance. The calculator handles a range of schemes, which are listed below.

  • Pension Contributions: Pension contributions form the most common scheme where the sacrificed salary is redirected as an employer pension contribution, fully exempt from employer NI.
  • Cycle to Work Schemes: Employees acquire bicycles and cycling equipment through salary sacrifice, which qualifies for NI relief.
  • Electric Car Arrangements: Electric car arrangements have gained popularity due to low benefit-in-kind rates, creating large tax efficiencies when combined with the 15% NI saving.

Each scheme reduces tax under HMRC rules, allowing the calculator to apply the standard saving rate across the arrangements.

What is salary sacrifice for pension contributions?

Pension salary sacrifice is an arrangement where an employee gives up part of their gross pay in exchange for an equivalent employer pension contribution. Pension salary sacrifice forms the most common type and lowers the pay subject to employer National Insurance (NI). The reduced gross salary cuts NI contributions for both the employer and the employee. Pension salary sacrifice requires a formal amendment to the employment contract to ensure compliance with legal requirements, such as maintaining the salary above the National Minimum Wage threshold.

How Much Employer NI Will You Save with Salary Sacrifice?

£5,000 sacrificed

£750

employer NI saved per year (£5,000 × 15%)

The saving equals the sacrificed amount multiplied by the 15% employer NI rate. For example, when an employee sacrifices £5,000 of their gross salary for a pension contribution, the employer saves £750 in National Insurance annually (£5,000 × 15% = £750). The calculation gives businesses a direct way to determine savings when implementing salary sacrifice schemes.

The drivers of the saving include the size of the sacrifice and the 15% employer NI rate. The larger the amount sacrificed, the greater the employer NI saving. Every pound sacrificed removes 15 pence of employer NI cost. The 15% employer NI saving belongs to the employer alone, separate from the employee's own income tax and NI savings. Employees save reduced income tax and employee NI contributions on the sacrificed amount, while the 15% employer NI saving belongs to the business. Employers reinvest the saving into the employee's pension, increasing the total pension contribution at no added cost to the employer, or retain the saving to reduce overall employment costs.

Is the salary sacrifice saving calculator accurate?

Yes, the salary sacrifice saving calculator is accurate when the salary, sacrifice amount, and tax year are entered correctly. The calculator applies the employer National Insurance (NI) rate to the amount of pay removed from NIable earnings. The result is as precise as the assumptions built into the calculator.

The salary sacrifice saving calculator assumes that the sacrificed benefit qualifies as NI-exempt under HMRC rules. The calculator does not automatically factor in the Employment Allowance unless that relief is manually applied or noted separately. For the 2026/27 tax year, the employer NI saving is based on the 15% rate and the secondary earnings threshold. Using the correct tax-year settings produces an accurate estimate. Employers should verify the calculator's results against payroll records and current HMRC guidance, above all for complex arrangements or multiple benefits. For scheme-specific results, professional advice from a tax adviser or accountant supports full compliance and accuracy.

What is the formula to calculate salary sacrifice?

The employer NI saving equals the sacrificed amount multiplied by 15%. The formula lets businesses determine the National Insurance savings when an employee enters into a salary sacrifice arrangement. The sacrificed amount refers to the portion of the employee's gross salary exchanged for a qualifying benefit, such as a pension contribution. The 15% employer NI rate is the current rate of employer National Insurance contributions applicable to earnings above the secondary threshold.

For example, when an employee sacrifices £2,500 of their gross pay, the employer NI saving is calculated as £2,500 × 15%, resulting in a saving of £375. The formula assumes the salary sacrifice arrangement is set up correctly and that the benefit is a qualifying one. The reduced gross salary through sacrifice means the employer avoids paying the 15% NI charge on that portion of pay, leading to direct savings.

Formula

Employer NI saving = Sacrificed amount × 15%

What is the gross salary and sacrifice amount?

The gross salary is the full pay an employee receives before any deductions or salary sacrifice. The sacrifice amount refers to the portion of the gross salary an employee chooses to exchange for a non-cash benefit, such as a pension contribution or a cycle-to-work scheme. The post-sacrifice salary is calculated by subtracting the sacrifice amount from the gross salary. The reduced salary determines the employee's taxable income and National Insurance Contributions.

How does the employer NI rate apply to the sacrifice?

The 15% employer National Insurance (NI) rate applies to earnings above the secondary threshold. The sacrificed amount is no longer subject to employer NI contributions when an employee opts for salary sacrifice. The salary sacrifice reduces the employer's NI liability by 15p for every £1 of salary sacrificed, provided the sacrificed amount exceeds the threshold. Removing the pay from the NI charge gives employers direct savings, making salary sacrifice a financially beneficial strategy.

What Is Salary Sacrifice?

Salary sacrifice is an arrangement where an employee gives up part of their gross salary in return for a non-cash benefit. The swapped pay is not subject to employer National Insurance (NI) or income tax. Salary sacrifice lets employees exchange a portion of their pre-tax earnings for benefits such as pension contributions, cycle-to-work schemes, or electric vehicle leases. The sacrificed amount is removed from the employee's contractual gross salary before tax and National Insurance calculations are applied, creating savings for both the employee and employer on their respective National Insurance obligations.

How Does Salary Sacrifice Work?

The employer reduces the employee's gross salary by the agreed amount and provides the benefit in its place, lowering the pay subject to employer National Insurance (NI). Salary sacrifice requires a change in the employee's contractual pay, processed through payroll, ensuring the sacrificed amount is deducted before taxation or NI charges are applied.

In practice, the employer pays a lower gross salary while providing the agreed non-cash benefit, such as an employer pension contribution. The contractual change must be documented in writing before the salary reduction occurs, ensuring legal compliance and accurate payroll records for HMRC reporting.

What Are the Main Types of Salary Sacrifice Scheme?

Salary sacrifice schemes let employees exchange part of their salary for non-cash benefits. Salary sacrifice schemes reduce the salary subject to employer National Insurance contributions, providing savings for both employers and employees. The main types of salary sacrifice scheme are listed below.

Pension Contributions

In pension contributions, employees give up part of their gross salary, which the employer contributes directly to the pension pot. Pension contributions form the most common type of salary sacrifice and help build retirement savings. Pension contributions reduce the amount subject to both employer and employee National Insurance, unlike personal pension contributions.

Cycle to Work

Cycle to work lets employees exchange salary for a bicycle or cycling equipment. The employer provides the equipment, which is exempt from National Insurance and income tax up to specified limits. Cycle to work supports sustainable commuting and generates the standard 15% employer NI saving on the sacrificed amount.

Electric Car

Electric car salary sacrifice has gained popularity due to favorable tax treatment. Employees give up salary in return for access to an electric vehicle through their employer. Electric car salary sacrifice offers a low benefit-in-kind rate, resulting in employer NI savings of 15% on the sacrificed salary, while employees pay minimal company car tax.

Childcare Voucher Legacy

Childcare voucher legacy schemes remain largely closed to new entrants and allow salary exchange for childcare vouchers. Childcare voucher legacy schemes stay valid for employees enrolled before October 2018, offering NI savings to employers. Tax-Free Childcare has replaced childcare voucher legacy schemes for new applicants.

The salary sacrifice schemes provide the same 15% employer National Insurance savings but differ in the benefits offered and applicable tax treatments. Employers must ensure that the chosen benefits are NI-exempt and do not reduce an employee's pay below the National Minimum Wage threshold.

Why Does Salary Sacrifice Save Employers Money?

Salary sacrifice saves employers money because salary sacrifice lowers the salary subject to the 15% employer National Insurance rate. The sacrificed portion is removed from the earnings on which employer NI is calculated when an employee agrees to exchange part of their gross pay for a qualifying benefit, such as a pension contribution. Employer NI is charged at 15% on earnings above the secondary threshold, so reducing the employee's contractual salary through sacrifice directly reduces the employer's NI liability.

Every pound sacrificed removes 15p of employer NI. The saving is immediate and applies to any qualifying salary sacrifice arrangement, whether for pension contributions, cycle to work schemes, or electric vehicle leases. The sacrificed amount multiplied by the 15% employer NI rate equals the annual saving. For example, when an employee sacrifices £5,000 of salary for a pension contribution, the employer saves £750 in National Insurance (£5,000 × 15% = £750). The saving accrues to the employer and stays separate from the employee's own tax and NI savings, which result from the reduction in their gross taxable income.

What is the purpose of a salary sacrifice arrangement?

The purpose of a salary sacrifice arrangement is to reduce both employer and employee tax and National Insurance contributions while funding a benefit such as a pension. A salary sacrifice arrangement lets an employee give up part of their gross salary in exchange for a non-cash benefit, lowering the pay subject to income tax and National Insurance. The employer's National Insurance liability decreases, saving 15p for every pound sacrificed. The dual saving makes salary sacrifice a tax-efficient strategy, benefiting both parties. Employees should know that reducing gross earnings could affect certain statutory benefits and entitlements, such as statutory maternity pay, which are calculated based on gross pay.

Who Can Use Salary Sacrifice?

Any employee whose pay remains above the National Minimum Wage after the salary sacrifice can join such a scheme. Salary sacrifice requires formal agreement from the employer and changes to the employment contract. The employee cannot implement salary sacrifice without employer agreement. Employers must ensure that the post-sacrifice salary complies with minimum wage regulations and maintains the necessary threshold for National Insurance contributions. Salary sacrifice supports a range of schemes, including pension contributions, cycle to work, and electric vehicle arrangements, as long as the employee's income does not fall below the National Insurance primary threshold of £12,570 or exceed the threshold income limit for tapered personal allowance at £200,000.

Who Should Not Use Salary Sacrifice?

Employees whose pay would fall below the minimum wage floor, and those who would lose earnings-linked entitlements, should not use salary sacrifice. Salary sacrifice can reduce statutory maternity pay and other benefits based on gross earnings. Statutory payments such as Statutory Maternity Pay (SMP) and Statutory Sick Pay (SSP) are calculated on the lower, post-sacrifice salary rather than the original gross pay when an employee's salary is reduced through a sacrifice arrangement. Employees who rely on pay-related entitlements should weigh the impact before joining, because salary sacrifice reduces gross pay and can affect benefits based on actual earnings.

How Much Employer NI Do You Save With Salary Sacrifice?

The employer saves 15% of the sacrificed amount. For example, when an employee sacrifices £5,000 of their salary for a pension contribution, the employer saves £750 in National Insurance (£5,000 × 15% = £750). The immediate saving applies to any qualifying salary sacrifice arrangement where the benefit is exempt from employer National Insurance.

The per-employee saving increases with the size of the sacrifice. Larger sacrifice amounts generate proportionally larger employer NI reductions, making salary sacrifice an efficient way to reduce payroll costs while improving employee benefits.

Employer NI Saving on a Pension Sacrifice

The employer NI saving on a pension sacrifice is calculated at 15% of the sacrificed amount. For example, when an employee sacrifices £5,000 of their salary for pension contributions, the employer saves £750 in National Insurance. The employer NI saving stays independent of any savings the employee gains in their own National Insurance or income tax.

How Much Does Salary Sacrifice Save Employees?

The employee saves their own National Insurance (NI) and income tax on the sacrificed pay. The reduced gross salary is not subject to employee National Insurance contributions or income tax when an employee opts for salary sacrifice. For instance, when an employee sacrifices £5,000 of their £40,000 salary, the employee saves 8% employee NI (£400) and income tax at their marginal rate, 20% for a basic-rate taxpayer (£1,000), resulting in a combined employee saving of £1,400 on that sacrifice. The employee's net cost for a £5,000 pension contribution through salary sacrifice is only £3,600, compared to the full £5,000 they would pay from net income under a personal contribution arrangement.

The combined employer and employee saving makes salary sacrifice efficient, while the impact on pension and earnings-linked benefits remains relevant. Both parties save on National Insurance, the employer at 15% and the employee at 8%, so salary sacrifice delivers a total NI saving of 23% on the sacrificed amount, plus the employee's income tax relief. Employees must know that salary sacrifice reduces contractual gross pay, which can affect statutory maternity pay, statutory sick pay, and other earnings-linked entitlements that are calculated based on gross earnings. Pension contributions through salary sacrifice count toward annual allowance limits, and the arrangement cannot reduce pay below the National Minimum Wage threshold. Salary sacrifice remains one of the most tax-efficient methods for funding benefits such as workplace pensions, cycle-to-work schemes, and electric vehicle leases.

How Can Employers Set Up Salary Sacrifice Correctly?

Employers set up salary sacrifice by agreeing to the arrangement in writing and amending the employment contract before pay is reduced. The written agreement ensures that both parties understand the terms and that the sacrifice counts as a legitimate change to the employment terms. The arrangement must be formalized through a contractual change that states the employee is giving up part of their gross salary in exchange for a specified benefit, such as a pension contribution, cycle to work scheme, or electric vehicle lease.

Payroll must process the reduced gross salary, and the minimum wage floor must be checked. The payroll system calculates employer National Insurance, income tax, and employee National Insurance on the lower post-sacrifice salary, not the original gross amount. Employers must verify that the employee's pay after the sacrifice does not fall below the National Minimum Wage or National Living Wage threshold for their age and employment status. Salary sacrifice arrangements that breach minimum wage legislation are not permitted and can result in penalties.

How Salary Sacrifice Combines With the Employment Allowance

Salary sacrifice and the Employment Allowance both reduce the employer National Insurance bill and can be claimed together. The two methods work in tandem to lower overall employer NI liability. Salary sacrifice reduces the gross pay subject to employer NI for specific employees. The Employment Allowance lets eligible employers reduce their annual employer NI bill by up to a set amount, applied against the total NI liability across all employees.

Salary sacrifice reduces the NI base at the 15% rate on sacrificed amounts. The Employment Allowance then offsets the remaining employer NI liability. The layered method reduces total employer NI costs. The Employment Allowance is a fixed annual sum, while salary sacrifice savings scale with the amount sacrificed across the workforce. Employers should calculate salary sacrifice savings first, then apply the Employment Allowance to the residual NI charge. The ordered calculation gives a full understanding of the combined benefit and accurate cost forecasting for payroll budgeting.

Where Salary Sacrifice Savings Fit in Total Employment Costs

The employer NI saving from salary sacrifice fits within the wider framework of total employment costs, which include salary, employer National Insurance, and workplace pension contributions. The gross pay subject to employer NI is reduced when an employee opts for salary sacrifice, lowering the employer's total payroll expenses. The salary sacrifice saving shows as a direct reduction in the employer NI line within overall employment costs, rather than as an added benefit.

For example, when an employer pays a gross salary of £40,000 and an employee sacrifices £5,000 for a pension, the employer saves £750 in NI (15% of £5,000). The saving can be reinvested into the employee's pension, maintaining or even reducing total employment costs. The interaction between employer NI savings and total employment costs guides effective cost management and planning.

Keeping Your Salary Sacrifice Saving Estimate Accurate for 2026/27

The accuracy of your salary sacrifice saving estimate depends on using the current 15% employer National Insurance (NI) rate and the secondary threshold for the 2026/27 tax year. The estimate requires all calculations to align with the figures set for the period. Tax rates and NI thresholds are subject to annual adjustments by HMRC, so employers must input the most recent data into the salary sacrifice calculator.

Employers should use current-year figures in the calculator because even minor changes in the NI rate or threshold can affect the savings outcome. For the 2026/27 period, the formula applies the 15% NI rate to income above the secondary threshold, which is set at £5,000 per year. Updating estimates with the latest HMRC guidance keeps the salary sacrifice arrangement effective and the savings accurately reflected.
