Editorial standards
Every calculator on CALCULATORPRO is built and reviewed against the working standards in its field — IRS publications and FRB rate data for finance, Mifflin-St Jeor and Harris-Benedict for nutrition, current national tax brackets for income tax, peer-reviewed academic sources for physics and chemistry. We cite our sources at the bottom of each calculator page.
Formulas are refreshed at the start of each tax/calendar year and whenever a major regulatory change ships. We publish the last-reviewed date on the trust strip at the top of every calc page so you always know how current the underlying math is.
Corrections policy
If you find an error, please email us with the calculator URL, the inputs you used, and the result you expected. We respond within 48 hours and publish material corrections at the bottom of the affected page with the date of the fix.
