ToolSimpli's free calculators handle the everyday sums that are easy to get wrong on paper. Work out a loan or mortgage payment before you commit, check what a discount really saves you, split a bill fairly, or see how long it takes to reach a savings goal — each one runs instantly in your browser with no sign-up.
Money questions are the ones people ask most. The loan calculator, mortgage calculator, car loan calculator and EMI calculator all show the monthly payment alongside the total interest you'll pay, so you can compare offers on what they actually cost rather than on the headline rate. The compound interest calculator and savings goal calculator work the other way round, showing what regular saving turns into over time.
For day-to-day maths there's a percentage calculator, percentage change calculator, discount calculator, tip calculator and VAT calculator — quick answers for shopping, invoicing and splitting costs. On the health side, the BMI calculator and BMR calculator give you a reading plus the daily calorie figure that goes with your activity level.
Every calculator is free, needs no account, and keeps whatever you type on your own screen. Nothing you enter is stored. Pick a calculator below and get your answer in a couple of seconds.
