Everyday calculators
Everyday math, sorted: split the bill with tip, unit price at the store, hours worked, change and fuel use. TudoCalc's everyday calculators save you time and money.
Bill split
Split a restaurant bill among friends, including the tip, and see how much each person pays.
Trip fuel cost
Estimate how much fuel a trip will cost from distance, mileage and price.
Discount
See the discounted price and your savings, including a discount on a discount. Example: 30% then 20% is not 50% — the real cut is 44%.
