Bills, Tips and Commission Calculators

Tip Calculator, Bill Splitter, Commission Calculator and Utility Bill Estimator

Rates, shares and fixed charges

Most bills are a rate times a quantity plus a fixed part. A tip is a percentage of the bill, commission is a percentage of the sale, and a utility bill is a unit rate times usage plus a daily supply charge that you pay even when you use nothing. Separating the fixed and variable parts is what makes two bills or two plans comparable.

Checking a bill before you pay it

Every calculator here shows the working, not just the total. Use it to check a restaurant bill that has already added a service charge, a commission statement from an employer, or an energy bill against the meter readings you took yourself. Most disputes come from one wrong input, such as an estimated reading, and the breakdown shows which one.
