How to Calculate a Tip
Calculating a tip is simple: multiply the bill amount by the tip percentage and divide by 100. For example, a 20% tip on a $50 bill is $50 x 20 / 100 = $10. Add the tip to the bill for the total: $50 + $10 = $60.
Standard Tipping Guidelines in the US
For sit-down restaurant service, 15-20% is standard. Fine dining typically warrants 20% or more. Buffets are usually 10-15%. For delivery services, $3-5 or 15-20% of the order total is common. Bartenders typically receive $1-2 per drink or 15-20% of the tab. Hairdressers and barbers usually receive 15-20%.
Splitting the Bill Fairly
When dining with a group, the simplest approach is to split the total (bill + tip) evenly. If people ordered items at very different price points, you can ask for separate checks or use this calculator to figure out each person's fair share. Always calculate the tip on the full bill before splitting.
Quick Mental Math Tip Tricks
- 10% tip: Move the decimal point one place to the left. A $45.00 bill = $4.50 tip.
- 15% tip: Calculate 10%, then add half of that. $45 → $4.50 + $2.25 = $6.75.
- 20% tip: Calculate 10% and double it. $45 → $4.50 x 2 = $9.00.
- 25% tip: Calculate 10% and multiply by 2.5, or find 20% and add half of 10%. $45 → $9.00 + $2.25 = $11.25.
