About CrunchMyPay

CrunchMyPay is a collection of free calculators and plain-English guides for the paycheck questions U.S. workers actually ask: What will overtime add to this check? What is my salary per hour? What does my state take out? What happens to my unused PTO when I leave?

Who runs this site

CrunchMyPay is built and maintained by an independent developer. It is not affiliated with any employer, payroll provider, bank, lender or government agency, and no company pays to be featured or to have a result shown. The site may carry clearly labeled advertising; ads never change what a calculator computes.

We are not a law firm, an accounting practice or a financial adviser, and no page on this site has been reviewed by one. What we can offer instead is transparency: every number is traceable to a published official source, and every formula is printed on the page so you can check it.

Where the numbers come from

• Primary sources only. Tax brackets, wage bases, overtime rules and state wage-payment laws are taken from the agencies and legislatures that set them — the IRS (Publication 15 and the annual inflation adjustments), the Social Security Administration, the Department of Labor’s regulations in the Code of Federal Regulations, the U.S. Code, state tax departments and state statute books. Our paycheck, tax and wage-law pages end with a Sources list linking each one, with a note on exactly which figure or rule it supports.
• Law text over summaries. Where an agency overview page and the statute itself are both available, we cite the statute or regulation, because that is the text that actually governs.
• Tax year stated. Paycheck calculators use the 2026 federal tables and say so on the page, together with the assumptions they make (for example, standard deduction and no credits).

How the math is built and checked

• Written from scratch. The calculators and the shared paycheck tax engine behind the state pages are our own code — not a licensed widget or an embedded third-party form.
• Show the work. Calculator pages explain the formula they apply, and most walk through a worked example with real numbers, so you can redo the math on paper.
• Regression-tested on every release. Before any change goes live, an automated suite of more than 1,200 checks recomputes the worked examples and tax figures quoted across the site and blocks the release if a single one disagrees. The same release gate also checks every internal link and the page markup.
• Private by design. Calculations run entirely in your browser. The numbers you type are never sent to our server, stored or shared. We use cookie-free, aggregate analytics that record which page was visited and whether a calculator was used — never the values entered. See the privacy policy.

How pages are kept current

Each page shows a Last reviewed date. That date changes only when the page’s content is substantively revised — new rules, corrected figures, added sections — not when a site-wide template changes. Annual figures such as tax brackets, the Social Security wage base and state minimum wages are updated when the issuing agency publishes the new year’s values.

What a calculator can’t tell you

Calculators simplify. A real paycheck also depends on your W-4, benefits elections, local taxes and your employer’s policies, and a real legal question depends on facts a form can’t capture. Use our results for planning and sanity checks, and confirm important figures with your payroll department, a tax professional or your state labor agency.

Report an error

If a number looks wrong, email contact@crunchmypay.com with the page, the inputs you used, the result you got and the result you expected. Accuracy reports get priority over everything else, and every calculator and guide links to the contact page next to its review date.
