Free Payroll Tools & Calculators

Payroll calculators that answer real questions, fast

The gross to net pay calculator breaks down income tax, employee NI, pension, and student loan deductions so employees understand exactly what they take home. The employer cost calculator adds employer NI, pension, and on-costs to the salary so employers see the true cost of each hire.

Our contractor vs employee cost calculator compares the true cost of a contractor day rate against an equivalent employed salary including all on-costs. For HR tools, see our Human Resources tools. For accounting tools, see our Accounting tools.

Tax rates and thresholds change each tax year. Always verify figures with your payroll software or a qualified accountant before processing payroll.
