Split Bill Calculator

A split bill calculator helps you divide a restaurant bill, takeaway cost or shared expense between a group of people. It is a quick way to work out how much each person should pay, especially when tips or extra charges need to be included.

Use the calculator above to enter the total bill, number of people, tip percentage and any extra fixed amount. The results update instantly so you can see the total and the amount per person straight away.

How to split a bill fairly

To split a bill fairly, you usually need four things:

1. the total bill amount
2. the number of people paying
3. any tip percentage
4. any extra charge, such as a service fee or delivery cost

The basic formula is:

(Bill amount + tip + extra charges) ÷ number of people

This gives the equal share each person should pay.

When to use a split bill calculator

A split bill calculator is useful for many everyday situations, including:

• restaurant meals with friends
• takeaway orders at home or work
• shared taxi fares
• group holidays
• flatmate household costs
• office collections or shared purchases

Instead of estimating or trying to do the maths in your head, the calculator gives you a clear result in seconds.

Example: splitting a restaurant bill

Imagine your group gets a restaurant bill of £60. There are 3 people paying, and you want to leave a 10% tip.

• Bill amount: £60
• Tip at 10%: £6
• Total including tip: £66
• Per person: £22

That means each person should pay £22.

Example: splitting a takeaway with an extra charge

Suppose your takeaway costs £32, there are 4 people, you add a 10% tip, and there is an extra £3 delivery fee.

• Bill amount: £32
• Tip: £3.20
• Extra amount: £3
• Total: £38.20
• Per person: £9.55

This makes it much easier to settle up accurately.

Should you split the bill equally?

In many cases, an equal split is the simplest option. It works well when everyone ordered roughly the same amount or when the difference is small.

However, equal splitting may not feel fair if:

• one person ordered much more than the others
• some people did not drink alcohol
• one person joined late or left early
• extra items were only shared by part of the group

In those situations, a more detailed item-by-item split may be better. This calculator is best for equal bill splitting.

How tips affect the total

A tip increases the overall amount before the bill is divided. For example:

• a 10% tip on a £50 bill adds £5
• a 12.5% tip on a £80 bill adds £10
• a 15% tip on a £100 bill adds £15

Once the tip is added, the final total is split between the group.

Common split bill scenarios

Splitting a meal bill

This is the most common use. Enter the restaurant total, add any tip, and divide it by the number of diners.

Splitting bills with flatmates

You can also use the calculator for shared groceries, internet bills or home deliveries.

Splitting holiday costs

Shared travel, taxis, meals or supplies can be divided quickly between everyone in the group.

Splitting a bill with service charge

If a service charge is already included, you can either treat it as part of the bill amount or add it as an extra amount.

Why rounding matters

When a bill is divided between several people, the result does not always land exactly on the nearest penny. For example, a total of £20 split between 3 people equals £6.666… each.

In real life, payments have to be rounded. That means one person may pay a penny more or less depending on how your group decides to settle it.

This calculator rounds the per-person figure to the nearest penny for practical use.
