What this calculator does

This hourly wage calculator converts an hourly rate into weekly, monthly and annual gross pay. It is useful for comparing hourly work with a salary offer.

Formula used

Weekly pay equals hourly rate multiplied by regular hours, plus overtime hours multiplied by the overtime rate. Annual pay multiplies weekly pay by paid working weeks.

How to read the result

If hours change from week to week, run several scenarios. Monthly pay is shown as an annual average divided by 12, so actual pay dates can vary.

Assumptions

  • Uses gross pay before deductions.
  • Assumes the same weekly hours across the working weeks entered.
  • Does not include holiday pay rules, unpaid breaks or shift premiums unless entered through hours and rate.

Sources and checks

This calculator uses a standard public formula. Where rules or thresholds can change, source links are listed on the relevant page.

Frequently asked questions

Should I use 52 weeks?

Use 52 when the rate covers paid holiday or you are paid all year. Use fewer weeks if you are modelling term-time, seasonal or unpaid weeks.
