Hours of Life
Price to Hours of Work Calculator — How Many Hours Does This Cost?
What this calculator does
This calculator turns a price tag into the time you must work to earn that money after taxes. It is a quick reality check for impulse purchases.
The math, with a worked example
After-tax hourly wage = gross wage × (1 − tax rate ÷ 100). Hours to afford the item = item cost ÷ after-tax hourly wage. A $250 item at an $18/hour wage with a 20% tax rate takes about 17.4 hours of after-tax work to pay for.
Why this matters
Price tags lie by omitting the denominator: $250 is 17.4 hours of after-tax work at $18 an hour. Converting money to hours of your life is the fastest honesty test a purchase can face.
Methodology and transparency
Hours = price ÷ (gross wage × (1 − tax rate)). The tax input should be your effective rate, not your bracket, or the hours inflate. The model also prices only the item — add sales tax and any financing interest for the full hour count on big purchases. Everything runs in your browser; no data is sent or stored.

Common questions
What tax rate should I use?
Use your effective tax rate, including federal, state, and FICA. A quick estimate is 20–30% for most workers.
Does this include benefits deductions?
No. It uses a single tax rate. If you want more precision, add your 401k, health insurance, and other deductions to the tax rate.
Can I use this for salary workers?
Yes. Divide your annual after-tax income by your annual work hours to get your real hourly rate.
