Time Receipt

Money hides its real cost. See any price in the only currency you can't earn back — hours of your life.

Price

Your take-home pay / hour

Your pay after taxes, per hour worked — the money that actually reaches you. Not sure? Divide a recent paycheck by the hours it covered. This stays on your device.

What is it? (optional)

Try an example

How often?

A one-time price is one thing; a habit is another. Pick a cadence and Time Receipt projects the same cost across a whole year — so a daily coffee can read as days of your life.

This costs you

5.5hours

5.5 hours of your life

5.5

hours

Price ÷ your take-home pay per hour. The raw life-hours this costs.

0.7

workdays

Hours ÷ 8 hours per workday.

0.1

work-weeks

Workdays ÷ 5 days per work-week.

A few hours of your life.

You spend time, not just money.

The math, in the open

Every number above comes from one plain rule: hours = price ÷ take-home pay. This log shows that math and a local-only receipt id so you can check the work. Nothing here is sent anywhere.
