Practical financial calculators to help you plan, compare, and understand your money. Model investment growth with compound interest, calculate mortgage payments and amortization schedules, compare buying vs renting, convert currencies, and plan savings goals — all in your browser, completely free.

Seven financial calculators built on the math that actually matters: real amortization, compound growth with inflation, opportunity cost on the down payment, year-by-year projection tables. The buy-vs-rent comparison runs forty years by default so the mortgage-payoff inflection point is visible on the chart instead of cut off. Every chart exports as a high-resolution PNG, every projection table as CSV or JSON — ready to drop straight into a spreadsheet, a slide deck, or a financial planner's report. No account, no upsell, just the underlying numbers computed precisely in your browser.
