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. Split Easy Tip 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 to split a restaurant bill
To split a bill fairly, first build the final total: subtotal + sales tax + tip. Then divide that total by the number of people paying. This calculator recalculates the per-person share every time you change the bill, the tax, the percentage, or the group size, which makes it a practical split bill calculator for groups, road trips, and team lunches.
How much should you tip?
In the United States, sit-down restaurant tips commonly fall between 15% and 20% of the bill, with higher amounts for outstanding service and lower percentages at counter-service places. 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. Outside the US, tipping expectations vary widely by country, so check local norms when you travel.

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 Split Easy Tip — 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. Split Easy Tip 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. Split Easy Tip 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.
Is Split Easy Tip free?
- Yes. The calculator is completely free to use, with no account, sign-up, or download required.
Does Split Easy Tip 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 Split Easy Tip 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.
