USA Financial Tools
Six everyday calculators for USA-based decisions: mortgages, auto loans, compound interest, sales tax, tipping, and salary conversion.
All results are estimates based on the information you enter. Actual rates, taxes, fees and terms vary by lender, state, and locality — confirm details with your bank, dealer, or a qualified professional before making a decision.
Planning a big purchase?
Start with the Mortgage or Auto Loan Calculator to see a realistic monthly payment, then use the Compound Interest Calculator to plan how a down payment could grow if invested instead.
