Splitting evenly is quick and fair when everyone shares dishes. For separate orders, calculate each person’s items instead.
How to use the Split the Bill Calculator
- Bill amount (before tax)
- Tax
- Tip
- Number of people
Results update as you type, and every field accepts the units shown in its menu.
How it works
Tax and tip are added to the bill, and the total is divided by the number of people.
Tips
- Use the figures from your own bills and product labels – prices and appliance ratings vary widely.
- Look at yearly totals: small daily costs add up and make it easier to compare options.
- Round quantities up to whole packs, rolls or bulbs when you shop.
- Re-check the numbers when prices change; most results scale directly with the unit price.
Common mistakes to avoid
- Confusing watts (power) with watt-hours or kilowatt-hours (energy).
- Comparing prices without bringing them to the same unit first.
- Ignoring one-off costs such as installation, delivery or replacement parts.
Inputs explained
| Field | What to enter |

What each result means
- Total with tax and tip = [Bill amount (before tax)]×(1 + [Tax]÷100)×(1 + [Tip]÷100)
- Each person pays = [Total with tax and tip]÷[Number of people]
- Rounded up per person = ceil([Each person pays])
