Calculators

Everyday calculators for money, percentages, dates and simple statistics.

Calculators for money and everyday life: percentages, loans and EMI, interest, tax, discounts, tips, margins and returns — plus everyday answers like your exact age and the number of days between two dates. These online calculators cover the finance end of the site; pure maths lives with the math tools, and measurement conversions live in Unit Converters.

The Percentage Calculator handles the everyday percent questions, the Loan EMI Calculator breaks a loan into monthly payments, the Age Calculator gives an exact age in years, months and days, and the Tip Calculator splits a bill fairly. Homeowners, shoppers, freelancers and students checking homework budgets all end up here. For countdowns, timers and stopwatch jobs, head to the date calculators section instead. Every calculator is free, works in your browser, and needs no sign-up.
