Donaldson R F Cost in Work Hours Calculator
How long do you have to work to pay for it? Enter your take-home pay and a few prices to see each one as hours and days of work.
Perspective, not financial advice. This is a way of looking at prices, not a recommendation to buy or not buy. It does not calculate tax: enter your take-home pay after tax and National Insurance (or your local equivalents). Your details stay in your browser.
The figures above are examples: replace them with yours. Use 52 weeks if you count paid holiday as time you are paid for, or fewer if you want unpaid time off taken out.

How it works
Your take-home pay is converted to a yearly figure (per month × 12, per week × 52, or per hour as entered) and divided by the hours you work in a year (hours per week × weeks per year) to give your take-home pay per hour. Each price divided by that hourly figure is the time it takes to earn it; dividing by the hours in a working day (hours per week ÷ days per week) gives working days. For recurring costs the price is turned into a monthly cost (weekly × 52 ÷ 12, yearly ÷ 12) and shown as hours of work each month and as a share of your monthly take-home pay and your working time.
Limits. This first version has no tax option: it uses only the take-home pay you type in, so a rise in pay, overtime or a bonus taxed at a different rate will not be reflected. The hourly figure counts only paid working hours; commuting, unpaid overtime and the cost of working are not included, so your real hourly value may be lower. Time is not the only way to judge a price, so treat the result as one point of view. To work out take-home pay in the UK use the UK Take-Home Pay Calculator; to convert a salary to an hourly rate use the Salary to Hourly Calculator; for pricing your own time see the Freelance Rate Calculator.
