Who this calculator is for
This page multiplies a bill by a tip rate and, if you ask, divides the total by a headcount. It is for a table that has already decided the rate — or wants 15%, 18%, and 20% side by side — and does not want to do the cents in a noisy room. It will not tell you the local custom. In much of the United States a restaurant tip is ordinary. In much of Portugal it is not the same script, and a service charge may already be on the bill. Decide the rate somewhere other than the arithmetic, then use the arithmetic so the split is not the thing you get wrong.
The page opens on the tip tab. The dollar sign on the bill field is a label. A €64.50 bill uses the same product as a $64.50 bill.

About this tip calculator
A tip calculator multiplies a bill by a rate, then optionally divides the total by a headcount. Eighteen percent of €64.50 is €11.61, and the amount you pay is €76.11. The interesting choice is not the multiplication. It is whether the bill you typed is pre-tax, post-tax, or already includes a service charge.
Where tipping is not the local script, a percent on top may be optional or odd. The tool will still multiply. It will not tell you the custom. Decide the rate, then use the page so the split is not the thing you get wrong.
How to use each field
- Bill amount
- The amount the percent applies to. If your rule is “tip on food, not on tax,” type the pre-tax subtotal. If the only figure you have is a tax-inclusive total, type that and accept that you are tipping on the tax as well. If a service charge is already inside the number, you are about to tip on a tip unless you subtract the charge first.
- Tip percentage
- The rate. Presets on this tab are 10, 15, 18, 20, 22, and 25, which are the buttons people actually argue about at a US table. A different custom — rounding up to a note, a flat euro or two, nothing — may not be one of those buttons. Type the rate you mean. Tapping a preset replaces it.
- Split between (people)
- How many ways the total, not just the tip, is divided. 1 leaves the total intact. 0 is not a meaningful headcount; keep it at 1 or more. The split is equal. It does not know who ordered the wine.
- Tip, total, and per person
- The formula line shows tip plus bill, then the division. 18% of 64.50 is 11.61, the total is 76.11, and two people owe 38.055 each before you deal with the half-cent. Someone takes the extra cent, or you nudge the tip until the total divides in cents you can pay.
When to use this calculator
- The bill is an awkward amount and you want 15%, 18%, and 20% side by side.
- More than two people are splitting, especially by three, where cents do not land evenly.
- A card machine suggested a tip that looks high and you want 20% of the food subtotal as a comparison.

Walkthroughs
Three people, 20% on the pre-tax subtotal
The subtotal is $86.40 and the tax line is $7.55. The table’s rule is tip on the subtotal. Bill amount 86.40, tip percentage 20, people 3. Tip is 17.28. Total of subtotal plus tip is 103.68, which is not the amount on the card if tax is still unpaid. Add the tax back outside the tip: 103.68 + 7.55 = 111.23 to settle, before the split gets subtle. Per person on the tipped subtotal alone is 34.56, and then each person still owes a third of the tax, about 2.52. The calculator did the tip. You still have to add the tax line you deliberately left out.
If someone instead types 93.95 (subtotal plus tax) and tips 20%, the tip becomes 18.79. The extra 1.51 is the cost of the other rule. Either rule is coherent. Mixing them inside one sentence is how tables argue.
A bill that already has a 10% service charge
The printed total is €92, and a line says service 10% included. If you type 92 and add another 10%, you tip €9.20 on top of a charge that was already €8.36 or so of that 92 (because 92 / 1.10 = 83.64, and the charge is the rest). Subtract first if you do not mean to double it. Type 83.64 and then decide whether any further tip is warranted. The page will not parse the receipt.
Formula
| Goal | Formula |
|---|---|
| Tip amount | bill × (tip% ÷ 100) |
| Total | bill + tip |
| Per person | total ÷ people |
Tip = bill × (rate ÷ 100). Total = bill + tip. Per person = total ÷ people. There is no tax estimator hiding in the formula. Whatever you typed is the whole the rate sees.
An 18% tip is not “20% minus a little” in a way you should compute from the 20% figure by guessing. 20% of 64.50 is 12.90. 18% is 11.61. The difference is 1.29, which is 2% of the bill, and it is worth knowing if the table is debating those two buttons. 15% is 9.675, which money usually rounds to 9.68. The page keeps more precision than a cash drawer. You still have to pay a coin that exists.
Equal splits of unequal orders feel fair only when the table agreed to pool. One €40 dish among four modest plates disappears into the average. Split the food in proportion first if that was the deal, then tip on each share, or tip on the whole and divide the tip by the same weights. This page only does the equal version.
Mistakes this page will not catch for you
Tipping on a bill that already includes a tip
If a service charge or a previous gratuity is inside the number you type, a new 20% tips that tip. Subtract the charge first, or accept that you are being generous on purpose.
Equal split of unequal orders
Dividing the grand total by headcount is fair only when you meant to share the cost. One expensive dish disappears into the average. Split the food first if the group did not agree to pool it.
Dividing the tip and forgetting the bill
The per-person figure on this page is a share of the total, not a share of the tip alone. The detail line also shows the tip per person. If four people each “put in the tip” using the total-per-person number, the restaurant gets paid four times.
FAQ
- How much should I tip?
- Common restaurant tips in the US are 15–20% of the pre-tax bill. Use 18–20% for good service. Local customs vary.
- Do I tip on tax?
- Many people tip on the pre-tax subtotal. Some tip on the full bill. Either is fine—pick a consistent rule.
- Do I include tax in the bill field?
- If a separate tax line exists and your rule is “tip on the meal,” leave the tax out. If the only number on the menu is a tax-inclusive total, tip on that number unless you have a reason to extract the tax first. Say which rule you used.
- Why doesn’t the per-person amount always divide cleanly?
- Cents are discrete. €76.11 divided by 2 is €38.055. Someone pays the extra cent, or you round the tip until the total divides. The percent did not fail; coins did.
- What is a normal tip?
- There is no universal one. In the US, 15–20% of the restaurant bill is a common range, often on the pre-tax subtotal. In many European countries the menu price is the price and a small extra is optional. Follow the custom of the place you are sitting, and the printed service charge, rather than a button on this site.
- Why did two people not land on even cents?
- Because cents are a hundredth and the total was not an even number of them. 76.11 divided by 2 is 38.055. Round the tip to a nearby cent that makes the total divisible, or let one person pay the extra cent. The percent is not the part that failed.
- Can I tip 0%?
- Yes. The tip is zero and the total equals the bill. That is a choice about custom and service, not a calculator error. Splitting still divides the bill.
