Compound Interest Calculator

Compound Interest is a calculator for savings and investment growth. See how much you'll have in N years, with compounding, regular contributions, tax and inflation taken into account — fast, clear, and accurate to the cent. What it does: • Results update as you type — no "Calculate" button • Compounding and contributions can run on different schedules (e.g. interest monthly, contributions yearly) • Contributions at the start or end of a period — this changes the result over long terms • Income tax adjustment (customizable) • Inflation adjustment — shows the real purchasing power of the result • Three currencies: RUB, USD, CNY • Growth chart and a detailed period-by-period table • Compare up to three scenarios side by side — different rates or terms, for example • Saved calculation history • Export to PDF and CSV All calculations run on your device and are never sent anywhere. This is a mathematical projection, not investment advice: figures are estimates that don't account for fees or market risk.
