Interactive Tip & Bill Split Calculator
What this tool does and who it is for
Enter the bill, choose a tip percentage and a party size, and the tip calculator shows the tip, the total and what each person owes. Preset percentage buttons and a slider cover most situations, and a round-up toggle bumps the total to the next whole dollar.
The defaults are a $85 bill and 20%, which is a common figure at US sit-down restaurants. Change them to suit the service, and note that the split is even, so everyone pays the same share.
It tips on the amount you type in. Many people tip on the pre-tax subtotal, so enter that rather than the total if that is your habit.
Official Formula / Technical Standard
Real-World Worked Scenario
Entering baseline parameters produces an instant, real-time mathematical breakdown with side-by-side comparative totals.
When people use it
Splitting dinner with friends
Enter the bill and party size to get an equal per-person amount, tip included.
Rounding up to a clean total
Turn on the round-up option so the total lands on a whole dollar, which is easier for cash or card splitting.
Comparing tip levels
Click through 15, 18 and 20 percent to see the dollar difference before you decide.
Tipping on delivery or services
Use it for rides, salons or delivery, where percentage customs vary, by typing the service cost and a percentage you consider fair.
Notes for US users
- In the US, tipping is a main source of income for many service workers, and 15 to 20 percent at a sit-down restaurant is a widely cited norm, though customs differ.
- Some restaurants add an automatic gratuity for large parties. Check your check before adding a second tip.
- Whether to tip on the pre-tax amount or the total is a matter of preference. Enter the number you want the percentage applied to.
- Cash tips are income for the worker, and card tips are usually paid out later, so either method works.
Limits and what to double-check
- •The split is equal only. It does not handle separate orders, shared appetizers or uneven shares.
- •The percentage applies to the bill amount you enter, and the tool does not know about tax or fees on your receipt.

Frequently Asked Questions
How does the Tip Calculator work?▼
The Tip Calculator runs 100% inside your web browser using modern client-side JavaScript. It performs calculations, conversions, and document processing locally on your device without sending any data to external servers.
Is this tip calculator completely free to use?▼
Yes. This tool is completely free with no usage limits, no subscriptions, and no registration required.
Is my data private when using the Tip Calculator?▼
Yes. Because all operations execute locally on your computer or phone, your inputs, documents, and data never leave your browser.
Should I tip on the total with tax or before tax?▼
Both are common. Tipping on the pre-tax subtotal is a bit less, and many people consider it perfectly fair. Tipping on the total is simpler and a little more generous. Whichever you choose, enter that amount as the bill in the tool.
What is a typical tip percentage?▼
At US sit-down restaurants, 15 to 20 percent is common, with 20 percent being a frequent default for good service. Counter service, takeout and delivery have looser customs. Adjust for the service you received and for local norms.
How does the round-up setting work?▼
It rounds the total, bill plus tip, up to the next whole dollar. The extra cents are added to the tip, so the tip amount shown increases slightly. It is handy when you want a tidy figure to pay or split.
Does it work for international trips?▼
The math works anywhere, but tipping customs differ widely by country, and in some places service is already included. Check local norms before applying a US-style percentage. The tool does not convert currency.
