Tip Calculator
Calculate a tip, add sales tax and split the bill. Choose 15%, 18%, 20% or your own percentage; results update as you type.
If your bill already includes tax, enter its total as the bill and leave sales tax at 0. Check for an included service charge before adding another tip.

How to calculate a tip
Multiply the bill by the tip percentage divided by 100. A $50 bill with an 18% tip adds $9, making $59 before any separate tax. Split between two people, that is $29.50 each.
Tip = tip base × percentage ÷ 100
Total = bill + tax + tip
Share = total ÷ people
15%, 18% and 20% tip examples
| Bill | 15% tip | 18% tip | 20% tip | Total at 20% |
|---|---|---|---|---|
| $20.00 | $3.00 | $3.60 | $4.00 | $24.00 |
| $50.00 | $7.50 | $9.00 | $10.00 | $60.00 |
| $100.00 | $15.00 | $18.00 | $20.00 | $120.00 |
How do I calculate tip and tax?
For a $100 bill, $8 sales tax and a 20% pre-tax tip, the tip is $20 and the total is $128. Turn on “Include tax” to use $108 as the tip base instead: the tip becomes $21.60 and the total $129.60. Enter the tax amount, not the tax rate. Use the sales tax calculator if you only know the rate.
How does rounding a split work?
A $50 bill with an 18% tip split three ways totals $59. Without rounding, two people pay $19.67 and one pays $19.66. Rounding each total up makes everyone pay $20, so the total becomes $60 and the tip $10. It rounds the complete share, not the tip separately.
How much should I tip?
The Emily Post Institute’s US tipping guide suggests 15–20% of the pre-tax amount for sit-down service. These are etiquette suggestions, not a universal required rate. Customs vary by service and location, and an automatic gratuity or service charge may already appear on the bill.
Can I use 0% or split a bill unevenly?
You can enter 0% or a custom non-negative percentage. This calculator splits the total evenly and distributes leftover cents. For different items, unequal contributions or settling several purchases, use the group expense splitter.
Method: bill and tax are rounded to cents, then the tip is rounded to cents. Rounding each share can increase the final tip. Calculations run in your browser; saved calculations stay in this browser. See About ONLINTools or report an error.
