How accurate are these calculators?
Each calculator uses the standard formula for its topic, shows the formula on its page and includes a worked example, so you can check the math yourself. They are designed for planning, estimates and everyday payroll checks.
- Pay calculators work on gross figures unless they say otherwise; tax depends on your local rules.
- Legal rules — overtime thresholds, breaks, leave minimums — vary by country, state and contract. The pages explain common rules but your local law always takes priority.
- The dollar sign is just a label: every calculator works with any currency.
When a calculator is not enough
If you are running these numbers every week for a whole team, the calculator is a symptom of a manual process. StaffTiming captures hours automatically and produces the same results — weekly totals, overtime, attendance rates, utilization, payroll-ready timesheets — for everyone at once.

Questions about the free tools
Are the calculators really free?
Yes. All 30 calculators are free to use with no sign-up, whether or not you use StaffTiming.
Do the calculators store my data?
No. Calculations run in your browser and nothing you enter is saved.
Can I use the calculators for any country?
Yes. The math works with any currency. Where rules differ by country — such as overtime or breaks — the page explains common approaches and reminds you to check local law.
