Formula
Tip = Bill x Tip% | Total = Bill + Tip | Per Person = Total / Number of People
The tip is a percentage of the bill subtotal. The total includes bill plus tip. When splitting, divide the total evenly or proportionally based on each person's order. Rounding up per person simplifies cash payments.
Worked Examples
Example 1: $120 Bill, 4 People, 20% Tip
Problem: Split a $120 bill 4 ways with a 20% tip.
Solution: Tip: $120 x 20% = $24.00\nTotal: $120 + $24 = $144.00\nPer person: $144 / 4 = $36.00\nRounded up: $36.00 (already even)
Result: Tip: $24.00 | Total: $144.00 | Per Person: $36.00
Frequently Asked Questions
How much should you tip?
In the US, standard tipping at restaurants: 15% for adequate service, 18-20% for good service, 25%+ for exceptional service. Pre-tax tip is traditional, but many calculate on the total. Other tipping guidelines: delivery drivers 15-20% ($5 minimum), bartenders $1-2 per drink or 15-20% of tab, hair stylists 15-20%, hotel housekeeping $2-5/night, taxi/rideshare 15-20%. In many countries outside the US, tipping is not expected or is much lower (5-10%).
Should I tip on the pre-tax or post-tax amount?
Traditionally, you tip on the pre-tax (subtotal) amount since you shouldn't tip on the tax the restaurant collects. However, many people tip on the total bill for simplicity — the difference is usually small (on a $100 pre-tax bill with 8% tax, 20% tip on pre-tax = $20, on post-tax = $21.60). Either approach is acceptable. What matters most is generosity, not precision.
How do I get the most accurate result?
Enter values as precisely as possible using the correct units for each field. Check that you have selected the right unit (e.g. kilograms vs pounds, meters vs feet) before calculating. Rounding inputs early can reduce output precision.
