Why four numbers beat every estimation method
Estimation advice is everywhere; your own history is the only data that is actually about you. Estimated hours against actual hours reveals your personal bias. Quoted against paid reveals how much price you give away after the quote is sent. Both corrections flow back into the project calculator as a suggested buffer, and both get sharper with every project you log. The medians are used instead of averages so one disaster project cannot distort your numbers.

Why should freelancers log finished projects?
Because estimation improves through memory, and memory is unreliable. Four numbers per project (estimated hours, actual hours, quoted, paid) are enough to reveal your personal bias. Most freelancers discover their estimates run 15 to 30% low, and knowing your own number beats every generic rule.
What is estimation bias?
The systematic gap between what you predict and what happens. If your last projects took 20% longer than estimated, your bias is +20%, and your future quotes should carry a buffer at least that big. This page computes it as the median of actual hours divided by estimated hours, so one disaster project cannot distort it.
Where is this data stored?
Only in your browser's local storage, like everything else on this site. Project names and amounts are never sent to any server; we could not read them if we wanted to. Export everything as a CSV file to keep a backup or move your log to another device, import it back anytime, or erase it all with one click.
