About TinyTools

TinyTools is a small, focused collection of calculators for one topic: turning work hours into pay. Time cards, hours worked, overtime, salary and hourly conversions, and take-home pay estimates for the United States, Canada, the United Kingdom, and Australia.

What we're trying to do

Most "work hours" and "pay" searches are answered by pages that bury a thin calculator under a wall of text, or by generic tools that ignore the messy parts — overnight shifts, multiple breaks, an overtime threshold that isn't 40 hours where you live. We build each calculator as a proper tool first: clear inputs, sensible defaults, a visible formula, and a result you can copy, print, or share.

How the calculators work

• Everything runs in your browser. There is no server doing the maths and nothing you enter is sent anywhere. The tools keep working offline once the page has loaded.
• One shared calculation engine. All the tools use the same tested TypeScript library, so a time card and the overtime calculator agree with each other. Money is handled in whole cents to avoid rounding drift.
• Sources are cited. Every overtime threshold and 2026 tax figure references the relevant statute or agency publication on the Methodology & Sources page. Where a rule is simplified or a jurisdiction isn't supported, the page says so rather than guessing.

Accuracy and limits

Results are estimates, not official figures or advice. Paycheck estimates currently cover US tax year 2026 and a limited set of states. See the Disclaimer for exactly what is and isn't modelled, and get in touch if you spot something wrong — corrections are welcome.

How the site is funded

TinyTools is free and supported by advertising. Ads are clearly labelled and kept away from the calculator controls and results so they can't be mistaken for part of a tool. See our Privacy Policy for how analytics and advertising cookies are handled.
