Tip and Bill Split Calculator
This tip and bill split calculator works out the tip, the total and what each person pays, with an option to round up.
Formula & worked example
Formula: Tip = bill × tip %. Total = bill + tip. Each person pays = total ÷ number of people (optionally rounded up).
Example: 126.40 with a 15% tip: tip 18.96, total 145.36, 36.34 each for four people; rounded up, 37 each.
Method & source: Simple percentage and equal-division arithmetic. See how we test our calculators.

Splitting a Bill and Calculating a Tip
A tool like this works out the tip on a restaurant or service bill and divides the total between everyone at the table. It replaces mental maths at the end of a meal with one clear amount per person.
It has quick tip presets, lets you enter any custom percentage and can round each share up to a whole unit so nobody has to find small change.
From Bill Total to Each Person's Share
Enter the bill before tip, choose a tip percentage and say how many people are sharing.
- Tip: bill × tip percentage.
- Total: bill plus tip.
- Per person: total divided by the number of people.
- Round up: optionally round each share up to a whole unit; the extra becomes a slightly bigger tip.
- Effective tip: the real tip percentage after rounding is shown.
The calculator splits the bill equally. If people ordered very different amounts, calculate each person’s own share separately.
Why Splitting a Bill Fairly Matters
Splitting a bill should not spoil the evening. Clear numbers keep things friendly.
- Avoid awkward mental maths at the table.
- Tip an amount that matches the service and local custom.
- Give every person one simple figure to pay.
- See the true effect of rounding up on the tip.
- Keep group meals, trips and shared costs fair.
Tipping customs differ between countries, so check whether a service charge has already been added to your bill.
Worked walkthrough: dinner for four
A restaurant bill comes to 126.40 for four people and you want to leave a 15% tip. The tip is 126.40 × 0.15 = 18.96, making the total 145.36, or 36.34 each. If you would rather each person pays a round 37, the total becomes 148, the tip grows to 21.60 and the effective tip is about 17.1% of the bill. The calculator shows both the exact share and the rounded share so you can decide which is easier for the group.
Practical tips for Tip and Bill Split calculations
- Check the bill first – many restaurants add a service charge automatically, and you may not need to tip on top of it.
- Decide whether to tip on the pre-tax amount or the total, and enter that amount as the bill so the percentage applies to the right figure.
- Use the quick presets for 10%, 12.5%, 15%, 18% and 20%, or type your own for special service.
- Rounding each share up is a quick way to leave a slightly higher tip without any change to hand around.
- If people ordered very different amounts, calculate each person’s own meal plus a share of shared dishes and tip separately.
Tipping customs differ from country to country
A tip is a discretionary thank-you on top of the bill, and what counts as normal depends on where you are. In the United States, 15–20% is common at sit-down restaurants. In the UK a discretionary service charge of 10–12.5% is often added to the bill already. In much of continental Europe service is usually included and people tend to round up a little, and in Japan tipping is generally not expected at all.
The presets in the calculator cover the usual range (10%, 12.5%, 15%, 18% and 20%), and you can type any percentage for exceptional service. Treat these as starting points and follow local custom.
Tip before tax or after tax?
The percentage is applied to whichever amount you enter as the bill, so the choice is yours. On a bill of 80.00 plus 8.00 tax, an 18% tip on the pre-tax amount is 14.40, while 18% on the 88.00 total is 15.84. The 1.44 difference is small per meal but adds up over a year of eating out.
If the bill already shows a service charge, check whether it is optional before adding a tip on top, so you do not pay for service twice.
Splitting a bill when meals cost different amounts
The calculator divides the total equally, which is fair when everyone ordered similar food. When orders differ a lot, split the bill by items instead: each person pays their own dishes, plus an equal share of anything shared, and then the same tip percentage on top.
For example, Ana ordered 30, Ben 50 and Cy 20, and they shared a 12 starter. Each adds 4 for the starter, giving 34, 54 and 24. With a 15% tip they pay 39.10, 62.10 and 27.60, which adds up to 128.80, exactly the 112 bill plus 15%.
What rounding up does to the tip
Rounding every share up to a whole unit is convenient for cash, and the extra money is added to the tip. The effective tip is therefore always at least the percentage you chose. With a bill of 47.80, a 12.5% tip and three diners, each pays 17.93. If everyone pays 18 instead, the total is 54.00, so the tip is 6.20 and the effective tip is about 13.0% of the bill.
Use the effective tip figure to check that rounding has not pushed the tip higher than you meant. If the bill only shows a total that includes tax, the reverse percentage calculator finds the pre-tax amount, and the discount calculator and VAT calculator handle other percentage jobs on a bill.
Frequently Asked Questions (FAQs)
Multiply the bill by the tip percentage. An 18% tip on a bill of 84 is 84 × 0.18 = 15.12, making the total 99.12.
It depends on the country and service. In the United States, 15–20% is common at restaurants; in the UK a service charge of 10–12.5% is often added to the bill already. Check your bill and local custom.
Add the tip to the bill and divide the total by the number of people. The calculator shows this as “each person pays”.
Many people tip on the pre-tax amount, others on the total. Enter whichever amount you want the percentage applied to as the bill.
It raises each person’s share to the next whole unit. The extra money goes to the tip, and the tool shows the new effective tip percentage.
An 18% tip on £80 is £14.40, so the total is £94.40 and each of four people pays £23.60. Enter your own bill, tip and group size to see the exact share.
Tap a preset of 10, 12.5, 15, 18 or 20 percent, or enter your own. The tip and total update immediately.
The total including tip is divided by the number of people, so everyone pays the same share of the bill and the tip.
12.5% of £50 is £6.25, so the total is £56.25. Change the percentage to compare other tips.
In the US, servers rely heavily on tips, so 15–20% is the usual expectation for sit-down service. Tipping less is a signal of poor service. Elsewhere, custom is different, so check the local norm and your bill.
