How to split a bill with tip and tax

  1. Start with the bill before tax (the subtotal).
  2. Work out the tax: subtotal × tax rate. Many receipts already show it.
  3. Work out the tip: subtotal × tip percentage.
  4. Add subtotal, tax and tip together for the total.
  5. Divide the total by the number of people.

Example: a 120.00 bill with 8% tax (9.60) and an 18% tip (21.60) comes to 151.20. Split four ways, that's 37.80 each. Splitting a bill evenly is fastest; when orders vary, an itemized split is fairer. For shared homes, see our guide on how to split rent fairly.

Bill splitting FAQ

How do you split a bill with tip and tax?

Add the tax to the pre-tax bill, calculate the tip (usually on the pre-tax amount), add it on, then divide the total by the number of people. For example, a $120 bill with 8% tax and an 18% tip is $120 + $9.60 + $21.60 = $151.20, or $37.80 each for four people.

Should you tip on the amount before or after tax?

Tipping on the pre-tax amount is the common convention in the US and Canada, and it's what this calculator does by default. Tipping on the post-tax total is also fine and results in a slightly larger tip.

What if people ordered different amounts?

An even split is unfair when orders differ a lot. Use an itemized split instead: each person pays for their own items plus a share of tax and tip in proportion to what they ordered. The Cost Share app does this automatically when you scan the receipt.

Why round up each share?

Rounding each share up to the nearest whole number makes cash and bank transfers simpler. The few extra cents usually go towards the tip.
