What it is
MakeCalculator is a free library of online calculators and tools built around one simple idea: a calculator should show its working, not just its answer. The site brings together 785 tools in one place, including loan, mortgage, tax and compound interest calculators for money decisions; BMI, BMR, TDEE and calorie calculators for health; unit converters for length, weight, temperature and data; maths tools from basic arithmetic to matrices and statistics; and a wide range of text, developer and PDF utilities.
Every calculator is built from the standard published formula for its subject and tested against worked examples before going live. Tools run in your browser, so your numbers stay on your own device. There is no sign-up required and results come with the formula or steps behind them wherever the tool allows it.

- MakeCalculator results are estimates provided for general information. For decisions with serious financial, medical or legal consequences, please verify the figures with a qualified professional.
