Frequently Asked Questions
How accurate are these calculators?
All calculators use standard mathematical formulas. Financial calculators use the same amortization and compound interest equations used by banks. Results match what you would get from a financial advisor's software.
Do you store my financial data?
No. All calculations happen in your browser. Your income, loan amounts, and other numbers are never transmitted to any server. There is no account, no history, and no tracking.
Can I use these for tax or legal purposes?
These calculators provide estimates for planning purposes. For tax filings, legal decisions, or binding financial commitments, always verify with a qualified professional.
