You fill in three things and pick a currency. The results change as you type, so there is no button to press.
The maths is simple. Tip = bill × percentage ÷ 100, rounded to the nearest cent. Total = bill + tip. Per person = total ÷ number of people, rounded to the nearest cent. Because the tool counts in whole cents, the Tip plus the bill is always exactly the Total. Yen has no cents, so for yen every result is rounded to a whole yen. The tool does not add tax, and it does not round the total up to a whole dollar.
Three friends have dinner. The bill is $85.50 and they want to tip 18%.
This one splits evenly: 3 × $33.63 = $100.89. Many bills do not, as the next section shows.
You cannot pay a third of a cent. So the per-person amount is rounded to the nearest cent, and the rounded shares can add up to one cent more or less than the total. When that happens, a line under the results says so. For example: 3 × $39.33 = $117.99, which is $0.01 short of the Total. So one person can pay $0.01 more. Here are real results from this calculator:
| Bill | Tip | People | Total | Each pays | Shares added up |
|---|---|---|---|---|---|
| $100.00 | 18% | 3 | $118.00 | $39.33 | $117.99 (1 cent short) |
| $50.00 | 15% | 3 | $57.50 | $19.17 | $57.51 (1 cent over) |
| $120.00 | 18% | 7 | $141.60 | $20.23 | $141.61 (1 cent over) |
| $60.00 | 20% | 4 | $72.00 | $18.00 | $72.00 (exact) |
A cent is not a big deal, but it helps to know why it happens. In a group, the easy fix is that one person covers the odd cent. If everyone rounds their share up to the next whole dollar, the server simply gets a slightly bigger tip.
Sometimes the exact tip ends in half a cent. At 15% of $85.50, the exact tip is $12.825. The calculator rounds half a cent up, so the tip is $12.83. The Total is the bill plus that rounded tip: $85.50 + $12.83 = $98.33. The two numbers always match, because the tool works in whole cents.
Both are common, and there is no fixed rule. Tipping on the amount before tax is the older custom. Tipping on the final amount is easier, because it is the biggest number on the receipt. The gap is small. For example, food of $80.00 with 8% sales tax gives a bill of $86.40:
| What you type in | Tip at 20% | You pay in the end |
|---|---|---|
| $80.00 (before tax) | $16.00 | $80.00 + $6.40 tax + $16.00 = $102.40 |
| $86.40 (after tax) | $17.28 | $86.40 + $17.28 = $103.68 |
The difference is $1.28. One thing to watch: if you type the amount before tax, the Total shown by the calculator ($96.00 here) does not include the tax. Add the tax yourself before you pay. Sales tax rates differ by place, so 8% is only an example.
This calculator splits the total equally. If one person had a salad and another had steak, an equal split may not feel fair. Instead, run the calculator once per person. Type each person's own share of the bill and leave Split Between at 1. For example, a $32.00 order at 18% gives a tip of $5.76 and a total of $37.76 for that person. Shared items, like a starter for the table, can be divided equally first.
Take 10% first. You get it by moving the decimal point one place to the left. On a $64.00 bill, 10% is $6.40.
The calculator gives the same answers: $12.80 at 20% and $9.60 at 15%.
How much to tip, or whether to tip at all, depends a lot on where you are. In the United States, tipping at sit-down restaurants is expected, and servers often rely on tips for a large part of their pay. In some countries, such as Japan, tipping in restaurants is generally not expected. In many other places, a service charge is already printed on the bill.
Before you tip, look at the receipt for words like "service charge", "service included" or "gratuity". Some restaurants add these for large groups. If a charge is already there, you may be tipping twice. When you travel, a local guide book or the hotel front desk can tell you what is normal.
No. It only works with the number you type in the Bill Amount box. If you type the amount before tax, the Total does not include tax, so add the tax yourself. If you type the final amount from the receipt, the tax is already inside it, and the tip is worked out on the amount with tax.
Each share is rounded to the nearest cent. For example, $100 with an 18% tip is $118.00. Split three ways, that is $39.33 each, which adds up to $117.99. A line under the results tells you this and says how to fix it: one person pays $0.01 more.
Not directly. The slider moves in whole steps from 0% to 50%. For 17.5%, check the tip at 17% and at 18% and take the middle. On an $80 bill, 17% is $13.60 and 18% is $14.40, so 17.5% is $14.00.
Yes. Pick USD, EUR, GBP, INR, NPR or JPY in the Currency menu. It changes the symbol on the results. Results have two decimal places, except yen, which has no cents and is rounded to whole yen. For another currency, pick any one with two decimal places and ignore the symbol.
An empty box counts as 1 person. 0, a negative number or a decimal like 2.5 shows a short note instead of results, because you can only split a bill between whole people. Type 1 or more.
Both are common. Tipping before tax is the older custom and costs a little less. On $80 of food with 8% tax, a 20% tip is $16.00 before tax or $17.28 after tax, a difference of $1.28.
