Tip & Bill Split Calculator

What is a tip calculator?

A tip calculator turns the gratuity guesswork at the end of a meal into a single number. Instead of doing percentages in your head while the server waits, you enter the bill, choose a percentage, and read the tip and total straight away. GetSplitTip goes one step further and also acts as a bill split calculator, dividing the final restaurant bill between everyone at the table.

How to calculate a tip

The formula is simple: tip = bill × (tip percentage ÷ 100). On a $80 meal with an 18% tip, that is 80 × 0.18 = $14.40, so the total comes to $94.40. If you prefer to calculate the gratuity on the post-tax amount, use the same formula with the total at the bottom of the check instead of the subtotal.

How tip splitting works

Everything starts with the bill amount. Type in the subtotal printed on your check — the cost of the food and drinks before any tax — and the calculator takes it from there. There is nothing to set up and nothing to sign; the tip, total, and per-person figures update as you type.

If you want to account for sales tax, open the tax option and enter the rate. You can also choose whether the tip is calculated before tax, on the subtotal, or after tax, on the full amount at the bottom of the check. Both approaches are common in the United States, and the difference is usually only a dollar or two — the calculator simply shows you the numbers either way.

The split itself is straightforward division. The tax and tip are added to the bill to reach the final total, and that total is divided evenly by the number of people paying. Change any value — the bill, the tax, the percentage, or the group size — and the per-person amount recalculates instantly, so nobody has to do math at the table.

How much should I tip?

In the United States, most people tip between 15% and 25% at sit-down restaurants. Of that range, 15% is generally the floor for service that was fine but nothing more; 18% to 20% is the standard range for good service and what most tables leave; and 25% or above is a way to reward truly exceptional service — a server who went well beyond the ordinary. At counter-service spots, tipping is appreciated but optional.

These are customs rather than rules — what you leave is always your decision, and service charges already added to the check may cover the gratuity. Tipping norms also vary widely outside the US: in much of Europe and Asia a service charge is often included and a small extra tip is all that's expected, so check local norms when you travel.

Typical Tip Amounts by Service

Tipping customs change depending on the service you receive. The table below shows common guidelines in the United States. Use these figures as a starting point, then adjust up or down based on quality, distance, complexity, and local norms.

Common tipping questions

Is tipping mandatory in the US?

Tipping is not required by law in the United States. It is, however, a strong social custom for many service jobs, and in restaurants tips often make up a meaningful share of a worker's pay. When service is satisfactory, leaving a tip is the usual practice.

Should I tip before or after tax?

Both methods are common. Tipping on the pre-tax subtotal is the traditional approach and costs slightly less. Tipping on the post-tax total is easier because it uses the final number printed on the receipt. Use whichever feels fair to you.

What if the tip is already included in the bill?

Some checks automatically add a gratuity or service charge, especially for large parties, events, or room service. Read the receipt carefully. If a tip is already included, you do not need to add more unless you want to reward exceptional service.

Do I need to tip for takeout?

Tipping on takeout is optional. A small tip is appreciated when staff carefully pack a large or complicated order, but it is not expected for a simple counter pickup.

Example calculation

Here's a quick worked example. A $60 bill split between 4 people with an 18% tip before tax comes to $70.80 total — that's $10.80 in tip added to the $60 bill — or $17.70 per person. The table below walks through a slightly larger bill with tax, so you can see every step of the calculation.

Frequently Asked Questions

What is a tip calculator?

A tip calculator is a tool that works out the gratuity on a bill for you. You enter the bill amount and the percentage you want to leave, and it shows the tip, the final total, and — with GetSplitTip — the amount each person in your group owes.

How do I calculate a 15% tip?

Multiply the bill by 0.15. On a $60 bill that is $9, giving a $69 total. A quick mental shortcut: take 10% by moving the decimal one place left ($6), halve it ($3), and add the two together.

How do I calculate a 20% tip?

Multiply the bill by 0.20, or take 10% and double it. On an $85 bill, 10% is $8.50, so a 20% tip is $17 and the total is $102.

How do I split a restaurant bill?

Add the tax and tip to the subtotal to get the final total, then divide that total by the number of people paying. GetSplitTip does both steps as you type, so you can read the per-person figure straight off the screen.

Should I calculate the tip before or after tax?

Both are common in the United States. Tipping on the pre-tax subtotal is the traditional approach and costs slightly less; tipping on the post-tax total is simpler because it uses the number printed at the bottom of the check. GetSplitTip lets you switch between the two with one tap.

Can I split the tip between multiple people?

Yes. The tip is added to the bill first, then the whole total is divided evenly by the number of people, so everyone covers an equal share of the food, tax, and gratuity.

What if people ordered different amounts?

The calculator divides the total evenly, which is the fairest method when everyone ordered roughly the same. If one person spent much more, the simplest fix is for them to cover the difference in cash, or to add their extra amount on top of an even split.

Does this work outside the US?

Yes. You can switch the currency to euros, pounds, or Canadian and Australian dollars, and enter whatever sales tax or service charge applies. Keep in mind that tipping customs differ by country — in much of Europe and Asia a service charge is often already included and a small extra tip is optional.

Can I split unevenly between people?

The calculator splits the total evenly so everyone pays the same share. For an uneven split, read the per-person figure here and settle the difference between yourselves, or run the calculation once for each group of diners who want to pay together.

Is GetSplitTip free?

Yes. The calculator is completely free to use, with no account, sign-up, or download required.

Does GetSplitTip store my bill information?

No. Every calculation runs in your own browser. Bill amounts, tax, and group sizes are never sent to a server or saved anywhere.

Can I use GetSplitTip on my phone?

Yes. The layout is built mobile-first with large tap targets, so it works comfortably on phones and tablets at the table, as well as on a desktop browser.
