What the Tip Calculator Does
This tip calculator estimates the tip amount, total bill, and per-person total from a bill amount, tip percentage, split count, and optional tax basis. It is designed for restaurant bills, delivery, services, and quick group checks.
Tip Formula
Tip amount = Bill amount x Tip percentage / 100.
Total = Bill amount + Tip amount. Per person = Total / Number of people. If tax is entered, the total also includes the tax amount.
Common Tip Formulas
| Use case | Formula | Example |
|---|---|---|
| Tip amount | Bill x tip % / 100 | $50 x 15% = $7.50 |
| Total with tip | Bill + tip | $50 + $7.50 = $57.50 |
| Split bill per person | Total / people | $120 / 4 = $30 each |
| Tip per person | Tip / people | $18 / 3 = $6 each |
| Effective tip after rounding | Rounded tip / bill x 100 | $8 / $50 x 100 = 16% |
How to Split a Bill
To split a bill with tip, calculate the tip first, add tax or service charges if needed, then divide the final total by the number of people. For itemized or uneven restaurant checks, use the Split Bill Calculator.
Tip Before or After Tax
In many cases people calculate tip before tax, while some tip on the after-tax total for simplicity. This calculator lets you compare either approach when tax is entered. Tipping customs and restaurant policies vary, so this is not a universal rule.
How to Round a Tip or Total
Rounding can make cash payments or group splits easier. You can round the tip amount, the final total, or the per-person total, but remember that rounding changes the effective tip percentage slightly.
Common Tip Percentages
Common quick options include 15%, 18%, 20%, and 25%. In the United States, 15% is often used as a lower restaurant tip, 18% to 20% is common for many sit-down meals, and 25% is a larger tip for strong service or personal preference.
Examples
- A $50 bill with an 18% tip split between 2 people has a $9 tip, $59 total, and $29.50 per person.
- A $100 dinner with a 20% tip has a $20 tip and $120 total before any tax or service charge adjustments.
- If a $100 subtotal has $8 tax, tipping 20% before tax gives a $20 tip; tipping 20% after tax gives a $21.60 tip.
- A $45 delivery or taxi fare with a 15% tip adds $6.75, for a $51.75 total before rounding.
- A $72 total split between 4 people is $18 per person; rounding to $20 each increases the total paid to $80.
Common Mistakes
- Forgetting to split the tip as well as the bill.
- Tipping on the wrong base if you intended to tip before tax.
- Confusing tip amount with the total amount due.
- Rounding inconsistently when splitting across a group.
- Forgetting service charges or automatic gratuity already added to the receipt.
- Assuming tipping customs are the same in every country, city, or service setting.
When to Use a Tip Calculator
Use a tip calculator when you want to compare 15%, 18%, 20%, or 25% tips, split a restaurant bill, estimate delivery or taxi tips, check before-tax versus after-tax tipping, or round a per-person total without doing mental math.

Frequently Asked Questions
Common questions about Tip Calculator and how to read the result.

A 15% tip is the bill amount multiplied by 0.15. On a $100 bill, that is $15.
What is a 20% tip on a bill?
A 20% tip is the bill amount multiplied by 0.20. On a $100 bill, that is $20.
Should I tip before or after tax?
Some people tip on the pre-tax subtotal, while others tip on the after-tax total for simplicity. Use the basis selector to compare both.
How do I split a tip between people?
Add the tip to the bill total, then divide by the number of people. This calculator also shows tip per person.
Is service charge the same as a tip?
Not always. If a service charge or automatic gratuity is already included, check the receipt or restaurant policy before adding more.
Can I enter a custom tip percentage?
Yes. Choose Custom in the quick tip percentage field, then enter your own percentage.
How do I round a tip?
Many people round the tip or final per-person total to the nearest dollar or convenient amount. Rounding is a personal choice and can slightly change the final total.
