Frequently asked questions

Are these calculators really free?

Yes — every calculator on WageWiseO is completely free, with no account, no signup, and no usage limits. Calculations run in your browser, so your numbers never leave your device.

How accurate are the tax calculators?

Our tax calculators use 2026 figures from the IRS (Revenue Procedure 2025-32), the Social Security Administration, and the Tax Foundation's 2026 state tax tables. Results are careful estimates for planning — see our disclaimer — and we refresh the data files every year.

Do you store the numbers I enter?

No. Everything computes locally in your browser with JavaScript. We don't see, store, or transmit anything you type into a calculator.

Which calculator should I use first?

Start with the paycheck calculator for take-home pay, the hourly-to-salary (or salary-to-hourly) converter to compare offers in the same units, and the overtime calculator if you work extra hours. Together they answer most pay questions.

How do I find the right calculator?

Use the search bar at the top of any page — start typing and matching calculators appear instantly. You can also browse the full directory or explore by category: Wage, Salary, Tax, Financial, Time, and Percentage.
