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.
