Free online calculators

These calculators handle the money and everyday math questions that are easy to get wrong by hand: loan EMIs and amortization, compound interest and investment growth, ROI, debt payoff strategies, budgeting, net worth, percentages, tips, and exact age. Each one shows the formula and a clear breakdown, so you understand the result rather than just reading a number.

Seeing the working matters most with finance. A loan calculator that reveals total interest, or a compound interest tool that separates your contributions from growth, helps you make better decisions than a bare figure ever could. Every calculation runs in your browser, so your numbers stay private.

For guidance, not advice

These tools are designed to inform and illustrate, not to replace a professional. For significant financial decisions, treat the output as a well-reasoned estimate and confirm the specifics with a qualified adviser. Pick a calculator above to begin.
