How it’s calculated
Tip
$84.50 × 18% = $15.21
Total
$84.50 + $15.21 = $99.71
How the tip calculator works
The tip is a percentage of the bill: the bill multiplied by the tip percentage and divided by 100, rounded to the nearest cent. Adding it to the bill gives the total, and dividing the total by the number of people gives each person’s share.
All amounts are calculated in whole cents, so the shares always add up exactly to the total. Nothing is lost or added by rounding unless you choose to round each share up.
The formula
Tip = Bill × Tip % ÷ 100
Total = Bill + Tip
Each person = Total ÷ Number of people
To tip on the pre-tax amount, use the bill minus the tax in place of the bill in the first line.
Worked example
A dinner bill is 84.50, and three people want to leave an 18% tip.
- Tip: 84.50 × 18 ÷ 100 = 15.21
- Total: 84.50 + 15.21 = 99.71
- Split three ways: 99.71 ÷ 3 = 33.2366…, so two people pay 33.24 and one pays 33.23.
With “round up each share” turned on, everyone pays 34.00. The total becomes 102.00 and the tip 17.50.
Assumptions and limitations
- Amounts are rounded to the nearest cent. The currency symbol only changes how amounts are displayed.
- The bill is split equally. If people ordered different amounts, calculate each person’s part separately.
- The calculator does not know local tipping customs or whether a service charge is already included.
Frequently asked questions
How much should I tip?
It depends on where you are and the kind of service. Tipping customs vary a lot between countries, and sometimes between regions and types of business. The buttons offer common percentages, not a recommendation. Check local guidance if you are unsure.
Should I tip on the amount before or after tax?
People do both. Tipping on the pre-tax amount means you are not tipping on the tax itself. The difference is usually small: on a bill with 8.00 of tax, a 20% tip changes by 1.60.
Why do some people pay one cent more when we split the bill?
Some totals cannot be divided evenly into cents. The calculator shares the total so the amounts add up exactly, and tells you how many people pay the extra cent.
What does “round up each share” do?
It rounds every person’s share up to a whole amount, which makes paying in cash or by card easier. The extra money goes to the tip, and the calculator shows the tip percentage after rounding.
What if the bill already includes a service charge?
Check the receipt. Some restaurants add a service charge or gratuity automatically, especially for large groups. If it is already included, you may not need to add a tip on top.
