Hiring is one of the biggest financial commitments a small business makes, yet the headline salary is only part of the story. On top of what lands in your employee's bank account, you carry Employer's National Insurance, a workplace pension and, for larger employers, the Apprenticeship Levy, plus statutory pay for holiday, sickness, maternity and notice. Those on-costs typically add 10% to 20% to a salary, and they're easy to underestimate when you're planning a budget or making an offer.
EmployerCosts brings every one of those calculations into one place. Each calculator gives an instant figure using the official HMRC rates and thresholds for the 2026/27 tax year, with the formula and a worked example behind it so you can see how the number is reached. From Employer's National Insurance and workplace pensions to redundancy, holiday and the full true cost of a hire, there's a dedicated tool for every question.
Built for UK employers
The calculators are framed the way a business sees costs: on-costs on top of salary, per employee and per team. Everything runs entirely in your browser. There is no sign-up, no paywall, and nothing you enter is stored or sent to a server.
Kept up to date
Tax rates change at every Budget. We review the figures against gov.uk guidance and keep every calculator on the current 2026/27 tax year, so you always know which rules sit behind the result.
