Frequently Asked Questions

Q: Are financial calculations processed securely?

A: Yes. All financial calculations run entirely in your browser using JavaScript. Your financial data, including salary figures, loan amounts, and tax information, never leaves your device and is never sent to any server. We do not store, log, or transmit any numbers you enter into our calculators.

Q: How accurate are the interest calculations?

A: Our compound interest and loan calculators use the standard amortization formulas used by banks and financial institutions. Results match those produced by major financial tools and spreadsheet software. However, actual loan terms may vary based on your credit profile, lender policies, and fees not captured in simplified calculations. Always verify critical financial decisions with your bank or financial advisor.
