About this calculator
A tip calculator works out the gratuity on a bill from a percentage you choose, adds it to the total, and optionally splits the whole thing evenly between a group so everyone pays their fair share. The tip itself is simply the bill multiplied by the tip percent and divided by 100; the per-person figure is the bill plus tip divided by the number of people.
For example, on a 50 bill at 18%, the tip is 50 × 18 ÷ 100 = 9, for a total of 59. Split between two people that is 29.50 each. Turn on "round up total" under advanced options to nudge the total to a whole number, which the calculator does by adjusting the tip.
Use it at restaurants, bars, cafes and for delivery or a taxi to tip quickly and settle a shared bill without the mental arithmetic. The comparison table shows the tip and per-person cost at 15%, 18%, 20% and 25% at once, so you can pick a level and see the total instantly.
Frequently asked questions
How much should I tip?
In the US, 15–20% of the pre-tax bill is customary for table service. Tipping norms vary widely by country — in many places it is optional or already included.
How do I split a bill with tip?
Add the tip to the bill, then divide by the number of people. This calculator does both — set the number of people under advanced options.
Do I tip on the pre-tax or post-tax amount?
Customarily you tip on the pre-tax bill, though many people simply tip on the total for convenience. Enter whichever bill figure you prefer as the starting amount and the calculator tips on that.
How much is a 20% tip?
A 20% tip is one-fifth of the bill: multiply by 0.20, or take 10% and double it. On a 50 bill that is 10. The built-in table shows 15%, 18%, 20% and 25% side by side.
How do I tip when the service was outstanding or poor?
For excellent service many diners go to 22–25% or more; for poor service some reduce it, though speaking to a manager is often more useful than a low tip. Just type the percentage you feel is fair into the tip field.
Is tipping expected everywhere?
No. In the US 15–20% for table service is the norm, but in much of Europe and Asia a service charge is often included and extra tipping is optional or small. Check local custom and set the percent accordingly.
