How to use it
- Enter the bill amount.
- Pick a tip percentage or type your own.
- Enter how many people are splitting the bill.
- Optionally round each share up to $5 or $10, then read what each person pays.
How the tip is calculated
Tip = bill × tip percentage ÷ 100
Total = bill + tip, and each person pays total ÷ number of people, rounded up to the next cent (or to the next $5 or $10 if you choose rounding).
Example: a $84.50 dinner for two with an 18% tip.
- Tip: 84.50 × 0.18 = $15.21
- Total: $99.71
- Each person: $49.86 (rounded up from $49.855)
With rounding to $5 per person, each pays $50.00, the total becomes $100.00, and the actual tip works out to $15.50, or 18.3%. The results table always shows the actual tip after rounding, so you know exactly what you are leaving.
Quick tip table
| Bill | 15% | 18% | 20% | 22% |
|---|---|---|---|---|
| $20 | $3.00 | $3.60 | $4.00 | $4.40 |
| $50 | $7.50 | $9.00 | $10.00 | $11.00 |
| $75 | $11.25 | $13.50 | $15.00 | $16.50 |
| $100 | $15.00 | $18.00 | $20.00 | $22.00 |
| $150 | $22.50 | $27.00 | $30.00 | $33.00 |
Mental math shortcut: for 20%, move the decimal point one place left and double it ($64 → $6.40 → $12.80). For 15%, take 10% and add half of that again.
How much to tip in the US
Tipping is customary in the US, and expectations vary by service and region. Common ranges people use:
- Sit-down restaurants: about 15–20% of the pre-tax bill, more for excellent service.
- Bars: about $1–2 per drink or 15–20% of the tab.
- Food delivery: often 10–20%, with a few dollars minimum for small orders.
- Taxi and rideshare: commonly 10–20%.
- Hair salons and barbers: often 15–20%.
- Counter service and coffee shops: optional; many people leave small change or use the tip screen.
These are customs, not rules. Tipping is your choice, and local norms differ.
Tipping when traveling abroad
Customs change at the border. In many European countries a service charge is included or a smaller tip, such as rounding up or 5–10%, is usual; in Japan tipping is generally not expected. In Canada, customs are similar to the US. The calculator works with any currency amount, so you can use it on the road too: choose a lower percentage preset or type the rate you need.
Service charges and auto-gratuity
Some restaurants add a service charge or automatic gratuity, often for larger parties. Check the bill before tipping so you don't tip twice. Tick A service charge or auto-gratuity is already on the bill and the calculator sets the extra tip to 0%; you can still add something extra for great service.
Should you tip on the amount before or after sales tax? Many people tip on the pre-tax subtotal, which is slightly less. Enter whichever amount you prefer to base the tip on; the calculator doesn't add tax.
Splitting the bill
Enter up to 50 people to split evenly. Each share is rounded up to the cent, so the group never comes up short; rounding to $5 or $10 per person makes paying in cash simpler. If people ordered very different amounts, calculate separate shares by running the calculator once per person with their own subtotal.

Frequently asked questions
How much should I tip?
In US sit-down restaurants, 15–20% of the pre-tax bill is common. Adjust for service quality and local custom.
How do I calculate a 20% tip?
Multiply the bill by 0.20. A quick way: move the decimal one place left and double it. On $45, that is $4.50 × 2 = $9.
Do I tip on the total with tax?
Many people tip on the pre-tax subtotal. Either way is acceptable; enter the amount you want the tip based on.
How does splitting work?
The total with tip is divided evenly by the number of people and each share is rounded up to the cent, or to $5 or $10 if you choose.
What if a service charge is already included?
Check the box for an included service charge. The tip is set to 0% so you don't tip twice, and you can still add more if you like.
