Split Bill Calculator
Splitting the bill with friends? Enter the total, tip, and number of people and you will see what each person pays. No awkward math at the table.
TL;DR
- You add the tip to the subtotal and divide the total by the number of people.
- Group Payment Formula: Per Person Share = (Subtotal + (Subtotal × Tip %) + Tax) ÷ Total People
- Example 1: Splitting a dinner among 4 friends with a 15% tip — Bill Subtotal: $100.00, Tip: 15%, People: 4
How it works
You add the tip to the subtotal and divide the total by the number of people. Choose whether the tip applies before or after tax.
The math
Find the tip as a percent of the subtotal, add tax, then divide by the number of people.
Compute the total tip, add the initial subtotal and any taxes, and divide the final sum by the count of active participants.
Examples
Example 1: Splitting a dinner among 4 friends with a 15% tip
- Bill Subtotal: $100.00, Tip: 15%, People: 4
- Calculate tip amount: $100.00 × 0.15 = $15.00
- Grand Total: $100.00 + $15.00 = $115.00
- Divide by 4: $115.00 ÷ 4 = $28.75 per person
Example 2: Bill with tax and custom tip splits
- Subtotal: $80.00, Tax: $8.00, Tip Rate: 20%, Diners: 2
- Tip Amount: $80.00 × 0.20 = $16.00
- Grand Total: $80.00 + $8.00 + $16.00 = $104.00
- Divide by 2: $104.00 ÷ 2 = $52.00 per person

⚠ Common mistakes
- Double-Tipping on Tax: Calculating the tip on the post-tax bill instead of the pre-tax subtotal, resulting in an accidentally higher gratuity.
- Rounding Too Early: Rounding decimal shares too early in the steps, causing the sum of individual payments to mismatch the original bill total.
