Tip Calculator
Work out the tip, the final total and how much each person owes. Adjust the tip percentage, add an optional tax rate and split the bill between any number of people.
How to Use the Tip Calculator
The Tip Calculator turns a restaurant bill into three clear numbers: how much to leave as a tip, what the final total comes to, and what each person pays when the bill is shared. It handles an optional tax rate and lets you choose whether the tip is based on the pre-tax subtotal or the post-tax total, because different countries and customs treat those two bases differently. Everything is calculated instantly in your browser and no figures are ever uploaded.
Enter the bill amount. Type the subtotal shown on the receipt — the amount before any tax or service charge is added. For example, enter 80 for an 80 bill. This is the figure the tip is normally calculated from.
Set the tip percentage. Type the percentage you want to leave, such as 15 for 15% or 20 for 20%. A tip of 15% on an 80 bill is 12, giving a total of 92. Raise or lower the percentage to see how the tip and total respond.
Add tax and choose the tip base. If tax is shown on the bill, enter the tax rate — for instance 8 for 8%. Then pick whether the tip should be calculated on the pre-tax subtotal or on the total after tax. Tipping on the pre-tax amount is common in the United States, while some people prefer to tip on the full total.
Split the bill. Enter the number of people sharing the meal. With 4 people and a total of 92, each person pays 23. The calculator shows the tip, the total, the tax, the subtotal and the per-person share, and the Copy result button puts all of it on your clipboard.
What Is a Tip Calculator?
A tip calculator is a small tool that computes a gratuity from a bill and then adds it to the amount owed. The core formula is simple: tip = bill × (tip percentage ÷ 100). A 20% tip on a 50 bill is 50 × 0.20 = 10, so the total becomes 60. When the bill is shared, the per-person share is simply the total divided by the number of diners: 60 ÷ 4 = 15 each. Tip percentages vary widely by country and setting. In the United States it is customary to leave around 15% to 20% at a sit-down restaurant, while in much of Europe service is already included and a smaller round-up is normal. Delivery drivers, bartenders and taxi drivers often have their own conventions. Because the expected amount differs so much from place to place, having a calculator that updates instantly makes it easy to check a fair figure before you pay. A frequent question is whether the tip should be calculated on the pre-tax subtotal or on the total including tax. Both are defensible: tipping on the pre-tax amount means you are rewarding service on the value of the food rather than on a government levy, while tipping on the full total is simpler and slightly more generous. This calculator lets you switch between the two bases so the result matches your habit. The optional tax rate field also separates the subtotal, the tax and the tip so the final receipt is easy to read.
Common Applications
1. Restaurant dinners: an 80 meal with a 15% tip comes to a 12 tip and a 92 total; split four ways that is 23 per person.
2. Group outings: a 240 bill with an 18% tip and 6 people gives a 43.20 tip, a 283.20 total and 47.20 each.
3. Delivery orders: a 35 order with a 10% tip is 3.50, a quick way to add a fair gratuity for a courier.
4. Cafés and bars: a 12 coffee round with a 20% tip is 2.40, so the total is 14.40.
5. Tax-aware tipping: an 80 subtotal with 8% tax and a 20% tip on the pre-tax amount gives 6.40 tax, a 16 tip and a 102.40 total.
How Much Should You Tip?
There is no universal rule, but common guidance in the United States is 15% to 20% for table service, around 10% for takeaway or delivery, and 15% to 20% for a taxi or rideshare. Bartenders are often tipped a dollar per drink or 15% to 20% of the tab. When service is already included in the price, as is usual in much of Europe, a small round-up is a friendly gesture rather than an obligation.
Tip on the Pre-Tax or Post-Tax Amount?
Tipping on the pre-tax subtotal is generally recommended when you want the gratuity to reflect the food and service rather than the sales tax. Tipping on the post-tax total rewards the same service slightly more because the base is larger. The difference is small: on an 80 subtotal with 8% tax, a 20% tip is 16 pre-tax but 17.28 post-tax, a gap of 1.28. Use the selector to match the convention where you are dining.

Frequently Asked Questions - FAQ
Is my data safe using this tool?
Yes. Every calculation is performed locally by JavaScript in your browser. No bill amounts are transmitted and nothing is stored on a server.
How do I calculate a tip?
Multiply the bill by the tip percentage and divide by 100. A 20% tip on 50 is 50 × 20 ÷ 100 = 10, making the total 60. If several people share the bill, divide the total by the number of people.
Should I tip on the amount before or after tax?
Both are acceptable. Tipping on the pre-tax subtotal is common because it rewards service on the food value rather than on the sales tax; tipping on the post-tax total is simpler and slightly more generous. This calculator lets you choose either base.
How do I split the bill evenly?
Enter the number of people in the Split between field and the tool divides the final total, including tip and tax, by that number. The per-person share is shown next to the total.
What tip percentage should I leave?
In the United States, 15% to 20% is typical for table service, around 10% for delivery and a dollar per drink at a bar. In countries where service is already included, a small round-up is usually enough. Check local customs when travelling.
