TidyCalcs — Free Online Calculators
Free calculators for mortgage, debt, health, and currency
TidyCalcs is a set of free, no-signup calculators for the math people actually search for — mortgage payments, refinance break-even, debt payoff (snowball vs. avalanche), credit card payoff timelines, BMI, calorie/TDEE needs, and live currency conversion for 150+ currencies. Everything runs in your browser. Nothing you type gets stored or sent anywhere.
Hey Product Hunt 👋
I built TidyCalcs because I kept landing on calculator sites that buried the actual number under five popups, an email-capture wall, or three pages of ads before you could see your result. So I built the version I wanted to use myself: type your numbers, get your answer instantly, no account, no email.
It covers the stuff people search for constantly — mortgage payments, refinance math, debt payoff strategy, credit card payoff timelines, BMI, calorie targets, and a currency converter for 150+ currencies — plus some guide articles for the "wait, how does this actually work" questions that come up alongside the numbers.
This is a brand-new project and I'm actively building on it, so I'd genuinely love feedback — what's confusing, what's missing, what feels slow on your phone. Thanks for taking a look.
