Gratuity Calculator
Type the bill, tap a common rate, and get the gratuity and grand total — quick math for a haircut, a cab, or a delivery.
How it works
Gratuity is just the bill times the rate. A $120 service at 20 percent is $24, for a $144 total. Tap one of the preset rates or type any percentage that fits the situation.
Different services carry different customs. Fifteen to twenty percent covers most sit-down and personal services, while quick counter interactions are often a couple of dollars or a small round-up.
When a venue already adds a service charge, check the receipt before adding more on top so you're not tipping twice by accident.
Frequently asked questions
What's a normal gratuity rate?
For personal services like a haircut, a spa visit, or a taxi, 15 to 20 percent is common in the US, with 20 percent or more for standout service. Adjust to the setting and how happy you are.
How is gratuity calculated?
Multiply the bill by the gratuity rate as a decimal. Twenty percent on $80 is $16, making the total $96. Enter the bill and rate and the calculator shows both figures.
Should I tip on the pre-tax amount?
Both approaches are common. Tipping on the pre-tax subtotal is a touch more traditional; tipping on the full amount is simpler and a little more generous. Enter whichever base you prefer.
What if a service charge is already added?
Check the bill first. If gratuity is included, you don't need to add more — though rounding up a bit for exceptional service is always welcome and never expected.
