A tip is just the bill multiplied by the percentage you choose; the total is the bill plus that tip, and splitting is the total divided by the number of people. This calculator does all three at once, so you can see the tip, the grand total, and the exact per-person amount on one screen.
What a tip calculator works out
There are only three numbers in play: the bill, the tip percentage, and the number of people splitting it. From those it derives three answers — the tip itself, the total including tip, and what each person owes.
The tip is the bill times the percentage. A $100 bill at 18% is a $18 tip. The total is the bill plus the tip — here $118 — and if two people split it, each pays $59. The calculator shows all of that without you reaching for a phone calculator at the table.
Everything else on the page is a view of those three numbers. The "tip per person" line is just the tip divided by the headcount, which matters when one person is covering the tip and everyone else is chipping in evenly.
How much to tip
In US table-service restaurants, 15% is the floor for adequate service, 18% is the common default, and 20% or more signals you were happy. Many card readers now pre-fill 20%, which has quietly moved the social norm upward.
The same 15/18/20 ladder roughly applies to taxis and rideshares, salon and barber services, food delivery, and bartenders (often $1–2 per drink). Counter-service and fast-casual spots do not expect a tip at all, though a tip jar by the register is optional.
Whether to tip on the pre-tax or post-tax amount is genuinely a coin flip. Tipping on the subtotal before tax is the older convention; tipping on the total is what most people do now and what this calculator does by default. Either is fine as long as you are consistent.
How to split a bill with this tool
- Enter the bill amountType the full pre-tip total from the receipt. No need to subtract anything — the tip is added on top.
- Pick a tip percentageChoose 10, 15, 18, 20 or 25%. If the service was memorable, 20–25% is the modern norm.
- Set the number of peopleEnter how many ways the bill is being split. The calculator divides the total including tip, so no one underpays.
- Read the per-person totalThe big number is exactly what each person should pay. The rows below break out the tip and the grand total.

Worked examples
- Bill $100 · 18% · 2 people
- $59.00 per personTip $18.00, total $118.00. Each of the two pays exactly $59.00.
- Bill $64.50 · 20% · 1 person
- $77.40 per personTip $12.90, total $77.40. A single diner covering their own meal.
- Bill $85.00 · 15% · 4 people
- $24.44 per personTip $12.75, total $97.75, split four ways is $24.4375 → shown as $24.44.
- Bill $250.00 · 20% · 5 people
- $60.00 per personTip $50.00, total $300.00, five people each pay $60.00 even.
The mistakes people make splitting bills
Rounding each person down. If the total is $97.75 and four people each pay $24, the server is short $1.75. Either round the last person up to cover the remainder or pool the cents — the calculator shows the unrounded figure so you can see the gap.
Tipping on the wrong base. Tipping 20% on the post-tax total instead of the subtotal adds a little, which is fine; tipping on a number that already includes someone else's tip double counts. The calculator takes the clean bill you enter, so the result is unambiguous.
Assuming an even split is fair when orders were not. This tool only does even splits. If one person ordered a $60 steak and another had a $12 salad, an even split puts the salad payer subsidising the steak. For unequal orders, add up each person's items first, then run the calculator on each subtotal.
What this calculator does not do
It does not decide the tip for you. The percentage is a judgement about the service, and the tool only applies the number you pick.
It does not handle itemised, uneven splits. It divides one total evenly. For groups where everyone ordered different amounts, sum each person's line items separately and calculate each subtotal on its own.
It does not convert currency. Bills in a foreign currency should be converted to your home currency first, then tipped — the percentages are the same, but the base amount must be in one currency.
It is not tax or accounting advice. Local customs and labour laws around tipping differ by country; the percentages here reflect US table-service norms.
Frequently Asked Questions
- How much should I tip at a restaurant?
- In the US, 15% is standard for adequate service, 18 to 20% for good service and 20% or more for excellent service. Many card readers now suggest 20% by default.
- Should I tip on the pre-tax or post-tax amount?
- Either is acceptable. Tipping on the pre-tax subtotal is traditional, but most people now simply tip on the total.
- How do I split the bill evenly?
- Enter the number of people and the calculator divides the total including tip, showing exactly what each person owes.
