Salary Calculator

Enter a pay figure and its period, plus your weekly hours and working days, to see the hourly, daily, weekly, monthly and annual equivalents at once. A month is the annual figure ÷ 12, not weekly pay × 4, which understates it by about 8%. All figures are gross, before tax and deductions.

Please note

All figures are gross pay before tax and deductions. Income tax, social contributions and pension rules differ by country and by individual circumstance.

How to use the Salary Calculator

  1. 1Enter a pay figure and say which period it covers.
  2. 2Set your usual hours per week and working days per week.
  3. 3Optionally set unpaid weeks off, which raises the effective hourly rate.
  4. 4Read every other period at once in the results table.

How it works

Everything is normalised to an annual figure first, then divided back out. That avoids the classic error of treating a month as four weeks: a year has 52.18 weeks, so a month is closer to 4.35 weeks. Multiplying a weekly wage by four understates monthly pay by about 8%.

Unpaid weeks off change the hourly figure but not the annual one. If you earn a fixed salary but take two unpaid weeks, you work fewer hours for the same money, so your effective hourly rate rises.

These are gross figures. Income tax, national insurance, pension contributions and other deductions vary far too much between jurisdictions and personal circumstances to model responsibly here.

The formula

annual = hourly × hours per week × (52 − unpaid weeks) monthly = annual ÷ 12
hourly
pay per hour worked
hours per week
your contracted or typical weekly hours
unpaid weeks
weeks off without pay

A month is annual ÷ 12, not weekly × 4. The difference is about 8%.

Worked example

25 an hour, 37.5 hours a week, no unpaid leave

  1. Weekly = 25 × 37.5 = 937.50
  2. Annual = 937.50 × 52 = 48,750
  3. Monthly = 48,750 ÷ 12 = 4,062.50

Result: 48,750 a year, 4,062.50 a month, 937.50 a week — all before deductions.

Tips and common mistakes

  • Compare job offers as annual figures, including the hours each one expects.
  • Remember a month is about 4.35 weeks, not 4, when converting weekly pay.
  • Enter unpaid weeks off if you have them; they change your effective hourly rate.
  • For pay after tax and deductions, use the Take-Home Pay Calculator.

Frequently asked questions

Why is monthly pay not weekly pay times four?
Because a year has 52.18 weeks, so an average month is 4.35 weeks. Multiplying by four understates monthly pay by roughly 8%.
Are taxes included?
No. These are gross figures. Deductions depend on your country, tax code and personal allowances.
How do unpaid weeks affect the result?
They raise your effective hourly rate on a fixed salary, because the same annual pay is spread over fewer worked hours.
How do I convert an hourly wage to a yearly salary?
Multiply the hourly rate by your hours a week and by the weeks you are paid a year. At 20 an hour, 40 hours a week for 52 weeks, that is 41,600 a year.
How do I convert an annual salary to monthly pay?
Divide by 12. A salary of 48,000 a year is 4,000 a month before tax.
How do I see my pay after tax?
This calculator works with gross pay. The Take-Home Pay Calculator estimates pay after tax for the UK, Canada, Australia and India.
