What it does
Job offers come in different shapes: some say 25 an hour, others 4,500 a month, others 52,000 a year. This tool turns any one of them into all the others, so you can compare offers fairly. It uses your real hours and the number of weeks you are paid, and it can add overtime on top.
Everything is before tax. To turn the result into spending, put it in the budget planner; to work out a raise or a change in percent, use the percentage calculator.
How to use it
- Choose what you know (hourly, daily, weekly, biweekly, monthly or yearly pay) and type the amount.
- Set Hours a week, Working days a week and Paid weeks a year.
- If you work overtime, enter the weekly overtime hours and what multiple of your pay they earn.
- Read the cards and the table of every period, with and without overtime.
What each setting does
- Hours a week: converts between hourly and weekly pay.
- Working days a week: converts between daily and weekly pay.
- Paid weeks a year: use 52 for a full year, or less if some time off is unpaid, for example 50.
- Overtime pays: 1.5 means time and a half; 2 means double time.
Worked example
25 an hour for 40 hours a week over 52 paid weeks is 52,000 a year. That is 1,000 a week, 2,000 every two weeks, about 4,333 a month and 200 a day. If you also work 5 overtime hours a week at 1.5 times, add 5 x 37.50 x 52 = 9,750 a year.
FAQs
Why is my payslip different? This is before tax, and employers may count months or pay periods differently.
Do salaried staff get overtime? That depends on your country and contract. Check your contract or the official rules.
What about holidays? Paid holidays count as paid weeks. Only unpaid time off should lower the paid weeks.
Where the numbers come from
- Plain arithmetic: yearly pay = hourly pay x hours a week x paid weeks a year. Monthly is a twelfth of the year; biweekly is two weeks of pay.
