> The split the bill calculator divides a restaurant or shared bill between people, adding tax and tip, and shows each person’s share rounded to a convenient amount.

## Inputs

- Bill amount (before tax)
- Tax (%)
- Tip (%)
- Number of people

## Results

- Total with tax and tip
- Each person pays
- Rounded up per person

## Formula

```
Total = bill × (1 + tax %) × (1 + tip %)
Each = total ÷ people
```

## Explanation

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.

### 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])

### Example values

How the main result changes when **Bill amount** changes and everything else stays at the example values above:
