Why the results here are trustworthy
Standard formulas. Payments use the conventional amortization formula; growth projections use period-by-period compounding rather than shortcuts.
Nothing hidden. Every page states what is and is not included, and shows the assumptions driving the result.
No data collection. Calculations run client-side. Amounts, rates and balances stay on your device.
