Hey Product Hunt! We built USACalculator because we were frustrated with calculator sites that are slow, cluttered with ads, or locked behind signups. So we built something better — 20 completely free, accurate calculators covering: Finance — Mortgage, Car Loan, Retirement, Debt Payoff, Student Loan, Credit Card Payoff, Compound Interest, Paycheck, Sales Tax Health — BMI, Calorie Utility — Unit Converter, Time Zone, Fuel Cost, Tip, Age, Anniversary Education — GPA Everything runs in your browser — your data never leaves your device. No signup. No paywall. Ever. Would love your feedback on which calculator you find most useful — and what we should build next! 🚀
