Finance calculators
Free calculators for everyday money questions: how fast savings grow with compound interest, what a loan really costs each month, how much a fixed-term deposit pays and how much to put aside to reach a goal. Results update as you type, and every page explains the formula behind the numbers with a worked example.
For questions about real market prices — what an investment in a stock, a cryptocurrency or gold would be worth today, or how regular monthly purchases would have performed — use the backtesting tools, which run on the same price history as our charts.
