What does this everyday calculator do?
The tip calculator takes a bill amount and a tip percentage and works out the tip, the grand total, and — when several people share the table — what each person pays.
It also shows a donut chart comparing the bill against the tip, so you can see the split at a glance, and the step-by-step math explains every number from percentage to per-person share.
Formula and variables
Tips are calculated on the pre-tax bill in most US restaurants, so a 20% tip is 20% of the food and drink total.
| Symbol | Meaning |
|---|---|
| Tip | bill × tip percentage ÷ 100 |
| Total | bill + tip |
| Per person | total ÷ number of people |
Worked example
A dinner bill is $80 and the party wants to tip 20%.
- Tip = $80 × 0.20 = $16.00.
- Total = $80.00 + $16.00 = $96.00.
- Split two ways: $96.00 ÷ 2 = $48.00 per person.
Answer: Each of the two diners pays $48.00.
Tips and common mistakes
Tips
- To estimate a 20% tip quickly, move the decimal point one place left to get 10%, then double it.
- Many people round the total to a convenient dollar amount so everyone pays an even figure.
- If service was exceptional or poor, adjust the percentage up or down before splitting, not after.
- When tipping on top of a discount, apply the tip to the discounted total you actually pay.
Common mistakes to avoid
- Tipping on the tax or the pre-discount amount, which inflates the tip beyond what most servers expect.
- Forgetting to include the tip when splitting the bill, leaving the last person to cover it.
- Using 15% of the post-tax total when the group intends 15% of the pre-tax bill — the amounts differ.
Tip Calculator — frequently asked questions
How much should I tip?
In the US, 15% to 20% of the pre-tax bill is customary for sit-down service, with 18% a common default and higher for exceptional service.
Is the tip based on the pre-tax or post-tax amount?
This calculator uses the pre-tax bill, the standard US convention. Some groups prefer tipping on the total including tax, which gives a slightly higher tip.
How do I split a tip evenly between people?
Divide the total with tip by the number of people. The calculator does this automatically in the per-person rows.
What is a typical tip percentage in other countries?
Service charges vary widely. In many European and Asian countries service is included, while in Canada and Australia tipping around 10% to 15% is common — check local custom.
Why does my credit card show a different total?
Some cards round each person's share or add the tip after the bill was split. Confirm the tip percentage on the final receipt.
Should I tip on a discount or coupon?
Most servers prefer a tip based on the full price of the meal, but the common practice is to tip on the amount you actually pay.
