Tip Calculator
Work out the tip and the total, split between everyone.
Good to know. For 10%, move the decimal point one place left. For 20%, do that and double it.
How it works
In plain words
Multiply the bill by the tip percentage to get the tip. Add it to the bill for the total, and divide by the number of people to split it.
The formula
tip = bill × (tip % ÷ 100) total = bill + tip each = total ÷ people
Worked example
A 15% tip on a bill of 85: 85 × 0.15 = 12.75, so the total is 97.75.

About the tip calculator
Tipping customs vary a lot around the world, so this calculator lets you choose any percentage. In the United States, 15–20% is typical at sit-down restaurants. In the UK, a 10–12.5% service charge is common and is often already on the bill. In much of Europe and Asia, rounding up or leaving a small amount is normal, and in some countries tipping is not expected at all.
A quick way to tip in your head is to find 10% by moving the decimal point one place to the left, then adjust. On 85, 10% is 8.50. Half of that again is 4.25, so 15% is 12.75, and doubling 10% gives 20%, which is 17.
Check whether a service charge is already included before you tip, so you don’t tip twice. Some people tip on the pre-tax amount and some on the total. Both are fine; just enter the amount you want to tip on.
If you are sharing the bill and want everyone to pay a round amount, the split the bill calculator can round each share up for you.
Questions people ask
How much should I tip?
It depends on the country and the service. In the US, 15–20% is standard at restaurants. In the UK, 10–12.5% is common. Elsewhere, rounding up is often enough.
How do I calculate a 20% tip quickly?
Find 10% by moving the decimal point one place left, then double it. On a bill of 85, 10% is 8.50, so 20% is 17.
Should I tip on the amount before or after tax?
Etiquette guides usually suggest tipping on the pre-tax amount, but many people tip on the total. Either is fine; enter whichever amount you prefer.
What if a service charge is already on the bill?
Then the tip is usually already covered. You can set the tip to 0% or add a little extra for great service.
