Free Online Calculators for Money, Health and Everyday Math
Some calculations come up so often they deserve purpose-built tools rather than a blank spreadsheet. These eight calculators cover the money, health and measurement math of everyday life — each with instant results and the formulas explained, so you understand the answer instead of just receiving it.
The financial set handles decisions with real stakes: the EMI Calculator reveals a loan's true cost with a full amortization schedule, the Interest Calculator demonstrates the power of compounding on savings, the GST/VAT Calculator adds or extracts tax correctly (including the reverse calculation most people get wrong), and the Discount Calculator exposes what stacked promotions actually save — and the difference between markup and margin that trips up new sellers.
For daily life, the Age Calculator gives calendar-exact ages and birthday countdowns, the BMI Calculator works in metric or imperial with WHO categories, the Percentage Calculator solves all three classic percentage problems side by side, and the Unit Converter translates length, weight, temperature and speed between metric and imperial with a full conversion table per value.
Everything computes instantly in your browser — no signup, and nothing you enter is stored or transmitted.
