What Tip Calculator does
A tip is the bill multiplied by the tip percentage, and an even split is the bill plus tip divided by the number of people. On a bill of 80 with a 15% tip, the tip is 12, the total is 92 and two people pay 46 each. This calculator works that out as you move the tip slider between 0 and 30%, for any group from 1 to 100 people. Tick Round each share up to lift every share to the next whole amount, so nobody is counting coins. A table underneath shows the tip, total and per-person cost at 10, 12.5, 15, 18, 20 and 25% for the same bill.
Tip chart: 15%, 18%, 20% and 25% on common bill amounts
Tip amounts from the calculator's own comparison table. Add the tip to the bill for the total.
| Bill | 10% tip | 15% tip | 18% tip | 20% tip | 25% tip |
|---|---|---|---|---|---|
| 10 | 1.00 | 1.50 | 1.80 | 2.00 | 2.50 |

Splitting a bill of 100: what each person pays with tip
Per-person share of a 100 bill once the tip is added, for groups of two to ten.
| People | 15% tip | 18% tip | 20% tip | 25% tip |
|---|---|---|---|---|
| 2 | 57.50 | 59.00 | 60.00 | 62.50 |
| 3 | 38.33 | 39.33 | 40.00 | 41.67 |
| 4 | 28.75 | 29.50 | 30.00 | 31.25 |
| 5 | 23.00 | 23.60 | 24.00 | 25.00 |
| 6 | 19.17 | 19.67 | 20.00 | 20.83 |
| 8 | 14.37 | 14.75 | 15.00 | 15.63 |
| 10 | 11.50 | 11.80 | 12.00 | 12.50 |
Shares are rounded to two decimals, so a split like three ways at 15% (38.33 each) collects 114.99 against a total of 115.00. Ticking Round each share up avoids the shortfall.
Worked examples: dinner for six, a quick lunch and a delivery
Dinner for six with an awkward total
Bill amount 237.85, Tip 18%, Split between 6 people
Tip 42.81, Total bill 280.66, Each person pays 46.78
With Round each share up ticked, each person pays 47.00 and the table collects 282.00.
Group of five, generous tip, rounded shares
Bill amount 184, Tip 22%, Split between 5 people, Round each share up ticked
Tip 40.48, Total bill 224.48, Each person pays 45.00
Unrounded, the share is 44.90.
Two people, default settings
Bill amount 80, Tip 15%, Split between 2 people
Tip 12.00, Total bill 92.00, Each person pays 46.00
Lunch for one
Bill amount 26.50, Tip 18%, Split between 1
Tip 4.77, Total bill 31.27, Each person pays 31.27
Small delivery order
Bill amount 12, Tip 15%, Split between 1
Tip 1.80, Total bill 13.80
On small orders a percentage can come out very low. Many people leave a flat amount instead.
Splitting with no tip
Bill amount 20, Tip 0%, Split between 2 people
Tip 0.00, Total bill 20.00, Each person pays 10.00
Set the slider to 0 when a service charge is already on the bill and you only need the split.
Tip and bill split formula
Tip = Bill × Tip % ÷ 100 Total = Bill + Tip Each person pays = Total ÷ Number of people With round up: each share is raised to the next whole number
Multiplying the bill by 1 plus the tip as a decimal gives the total in one step: a 20% tip is the bill × 1.20, and an 18% tip is the bill × 1.18. The split is always equal. Rounding up applies to each share after the division, so the group pays slightly more than the calculated total and the difference is extra tip.
Mental shortcuts for working out a tip without a calculator
- 10%: move the decimal point one place to the left. 84.00 becomes 8.40.
- 20%: find 10% and double it. 8.40 becomes 16.80.
- 15%: find 10% and add half of it. 8.40 plus 4.20 is 12.60.
- 18%: find 20% and take off a tenth of that. 16.80 minus 1.68 is 15.12.
- 25%: divide the bill by four. 84 ÷ 4 is 21.
- 5%: halve the 10% figure. 8.40 becomes 4.20.
Tipping on pre-tax or post-tax, service charges and uneven splits
Whether to tip on the amount before or after sales tax is a matter of preference. Etiquette guides generally suggest the pre-tax subtotal, since tax is not part of the service, and plenty of people tip on the final total because it is the number in front of them. The calculator has one bill field and no separate tax line, so enter whichever figure you want the percentage applied to. If you tip on the subtotal, remember to add the tax back when you pay.
Check the bill for a line reading service charge or gratuity before adding anything. Where one is included, as is common for larger groups and in many UK restaurants, a further tip is optional. Set the slider to 0 and use the calculator only to divide the total.
The split is equal shares only. It cannot divide a bill by what each person ordered or give one person a larger share. For an itemised split, run each person's own subtotal separately with Split between set to 1.
Tipping customs differ widely between countries and between kinds of service, so treat any percentage as a starting point and follow local practice.
Step by step
- 1
Enter the Bill amount. Use the pre-tax subtotal if you prefer to tip on that, or the full total if you do not.
- 2
Drag the Tip slider to a percentage from 0 to 30.
- 3
Set Split between to the number of people sharing the bill. Set it to 1 to work out a tip without splitting.
- 4
Tick Round each share up if everyone should pay a whole amount.
- 5
Read Tip, Total bill and Each person pays, then compare other percentages in the Common tip amounts table.
