How to Calculate Tips and Split Bills
Calculate restaurant gratuity, add applicable taxes and split the bill fairly with easy per-person examples. Use the free RapidCalc calculator to check your own numbers and explore different inputs.
Calculate tip from the bill
Tip = bill base × tip rate ÷ 100. For a $100 pre-tax bill and 18% tip, gratuity is $18. Confirm whether local custom uses a pre-tax or post-tax base.
Include tax separately
If a $100 bill has an 8% tax and an 18% pre-tax tip, tax is $8 and tip is $18. The combined total is $126.
Split among diners
For two people sharing the $126 total equally, each pays $63. If a group had three people, each would pay $42 before any rounding.
Round carefully
When the total cannot divide evenly to cents, round individual shares deliberately and make sure the combined shares still cover the bill. An upward rounding rule may create a small surplus.
Avoid double charging
Look for automatic gratuity or service charges on the receipt. Tax, included gratuity and optional extra tip are different items.
Try your own example
