Tip, loan, mortgage PITI, ROI/CAGR, and compound interest — all in one tool
Five of the most-searched financial calculators bundled into one tool — tip / loan / mortgage / ROI / compound interest. Each one does its job precisely (mortgage includes the tax and insurance pieces most online calculators omit; compound interest accepts regular contributions at configurable frequency). All math runs in your browser.
The math is exact. Real-world returns aren't guaranteed — 'S&P 500 averages 10%/year' is a historical average with wild year-to-year variance. Use the calculator for planning, not promises.
We compute principal + interest precisely. Tax and insurance are estimates — your lender has exact figures from the property assessor and insurance provider. We're ±5% of a typical quote.
No — assumes fixed rate. For ARM or variable, run the calculation at the current rate and again at the cap rate to see the range.
Compound Annual Growth Rate — the constant rate of return that would produce the same ending value. It smooths out year-to-year variance so you can compare investments of different durations.
Add your extra monthly payment as a 'contribution' in the compound interest calculator (though that's aspirational). A full amortization table is on the roadmap.
