A tip calculator is a free restaurant tool that calculates the gratuity and total bill, and splits it between any number of people. Our tip calculator supports custom tip percentages and rounds the split to the nearest cent. The tip calculator is used when dining out, for takeout, delivery, and other services that expect a tip.
How it works
Our tip calculator lets you figure out the right tip amount and split a restaurant bill between friends in three steps.
Type the total bill amount. Toggle 'pre-tax' or 'post-tax' depending on your local tipping custom. Most US guides suggest tipping on the pre-tax amount.
Choose 15%, 18%, 20%, or enter a custom percent. 18-20% is standard for good US restaurant service. Adjust up or down based on service quality.
Type how many people are splitting the bill, or leave at 1 if you are paying alone. The calculator shows the tip, total, and per-person amount.
The result shows the tip, the new total, and how much each person owes. Use the copy or share buttons to send the per-person amount to the group.
