Enter the bill and the tip percentage to see the tip, the total and what each person pays when you split it.

Also called: Gratuity calculator, Bill split calculator.

## Inputs
- Bill amount (default 80)
- Tip (unit %; default 15)
- Split between (unit people; default 2)
- Currency

## Results
- Total to pay
- Tip
- Each person pays
- Tip per person

## Formula

```
Tip = Bill × Tip% ÷ 100;  Total = Bill + Tip;  Per person = Total ÷ People
```

Where:
- Bill: the amount before the tip
- Tip%: the tip percentage
- People: how many people share the bill

## Worked example
1. Tip = 80 × 15 ÷ 100 = $12.
2. Total = 80 + 12 = $92.
3. Split between 2 people: 92 ÷ 2 = $46 each.

**Result:** A 15% tip on an $80 bill is $12, so the total is $92, or $46 each for two people.

## What the result means

Tipping customs vary a lot by country and by type of service. In some places a service charge is already on the bill, in which case an extra tip is optional.

## Assumptions and limits
- The tip is a percentage of the bill amount you enter, whether that is before or after tax.
- The total is split equally.
- Shares are rounded to the cent, so the individual amounts can differ from the total by a cent or two.

## Questions

### Should I tip on the amount before or after tax?

Either is common. Tipping on the pre-tax amount is slightly cheaper; enter whichever amount you want the tip based on.

### How do I work out 20% quickly?

Move the decimal point one place left to get 10%, then double it. For $45, 10% is $4.50, so 20% is $9.
