Financial Calculators

Plan, borrow, save, and invest with confidence. This directory collects every financial calculator on Calculator Archive: mortgage and amortisation schedules, loan and payment planners, retirement and pension projections, tax and take-home pay estimators, plus investment, savings, interest, and currency tools. Each one runs entirely in your browser, states the formula it applies, and lets you choose the compounding and payment frequency, so you can see exactly how a figure was produced rather than taking it on trust. Use the grouped list below to jump straight to a tool, and read the articles library for worked explanations of the mathematics behind mortgages, compound interest, inflation, and retirement planning.
