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

After-tax hourly wage = gross wage Γ— (1 βˆ’ tax rate Γ· 100). Hours to afford the item = item cost Γ· after-tax hourly wage.

Worked example

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

Most people underestimate the cost of small interest and fee decisions. This calculator turns the hidden math into a number you can act on today.

Methodology and transparency

This page publishes the exact formula used to compute the result, so you can verify it in a spreadsheet or check the assumptions against your own situation. The worked example uses the tool default inputs; change any number and the result updates live 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.
