How to Calculate a Tip
Calculating a tip is straightforward: multiply the bill amount by the tip percentage, then divide by 100. For example, a 20% tip on an $85 bill is $85 x 20 / 100 = $17. The total bill becomes $102, and if splitting between two people, each pays $51.
This calculator makes the process instant. Enter your bill amount, choose your tip percentage, and specify how many people are splitting the bill.
Tip Calculation Formula
The formula for calculating a tip is simple:
- Tip Amount = Bill Amount x (Tip Percentage / 100)
- Total Bill = Bill Amount + Tip Amount
- Per Person = Total Bill / Number of People

Tips for Fair Bill Splitting
- Use apps: Payment apps like Venmo and Splitwise make it easy to split bills precisely.
- Round up: When splitting, round up slightly to ensure the server gets a full tip.
- Communicate beforehand: If splitting evenly, mention it before ordering so everyone orders in a similar range.
- Consider itemized splitting: For groups with very different orders, calculate each person share separately.
- Be generous: When in doubt, tip more. Servers often depend on tips as a significant portion of their income.
Tip Calculator FAQ
How much should I tip at a restaurant?
In the United States, the standard tip at a sit-down restaurant is 15-20% of the pre-tax bill. For exceptional service, 20-25% is common. For buffets, 10% is typical, and for takeout, 10-15% is appreciated but not expected.
Should I tip on the pre-tax or post-tax amount?
Tipping on the pre-tax amount is technically correct and more traditional. However, many people tip on the total bill including tax for simplicity. The difference is usually small, and either approach is acceptable.
How much do you tip for delivery?
For food delivery, tip 15-20% of the order total, with a minimum of $3-5 for small orders. For grocery or large item delivery, $5-10 or 15-20% is customary. Consider tipping more in bad weather or for difficult deliveries.
How do I split a bill evenly?
Add the tip to the total bill, then divide by the number of people. This calculator handles this automatically. For fairness when orders differ significantly, you can calculate each person share based on what they ordered plus their portion of the tip.
Is tipping different in other countries?
Yes, tipping customs vary widely. In Japan and South Korea, tipping can be considered rude. In most of Europe, a service charge is often included. In Canada and Mexico, tipping is similar to the US at 15-20%. Always research local customs when traveling.
