loancalculators.app is a free suite of financial calculators covering mortgage payments, auto loans, personal loans, student loans, compound interest, salary conversion, tip calculation, sales tax, credit card payoff, retirement planning, savings goals, refinancing, home affordability, debt-to-income ratio, and paycheck estimation. All 15 calculators are free, instant, and private.
All calculations run entirely in your browser using pure JavaScript math with standard financial formulas. No data is ever sent to a server. You can verify this by opening your browser's Network tab — you will see zero outbound requests when you use any calculator. Your numbers stay on your device.
We use standard financial formulas: the PMT formula for loan payments, compound interest formula for investment growth, and current tax brackets for paycheck estimates. Results are accurate for standard fixed-rate loans and investments. Variable-rate products, complex tax situations, or unusual loan structures may differ from estimates. Always consult a licensed financial advisor before making major financial decisions.
Since all calculations happen client-side, your financial information never leaves your device. We use Google AdSense for advertising, which may use cookies for ad personalization. We also use localStorage to remember your last inputs so returning visitors see their previous calculation. See our Privacy Policy for details.
