How to Split a Bill Fairly

A simple method for splitting a shared bill with tax, tip and unequal shares.

Splitting a bill is easiest when everyone agrees on the total before deciding each person’s share. Start with the base bill, then add tax and any voluntary tip. Only then divide the total.

Equal shares

For an equal split, divide the complete total by the number of people. If the result includes a small remainder, agree whether to round up, round down or have one person cover the difference.

Unequal shares

If people ordered different items, first assign each item to the right person. Then decide how to share tax, service charges and tip. A proportional split may be fairer than dividing every charge equally.

Check the total

Add all individual payments back together. They should match the bill total after rounding. This simple check prevents a missing charge or accidental double payment.

Tip decisions

Tip customs vary by place and service. The calculator can apply the percentage you choose; it does not decide what amount is appropriate.

Quick questions

Should tax be split equally?

Equal splitting is simple, but a proportional split may fit a bill with very different item values.

What if one person pays cash?

Record that amount first, then divide the remaining balance among the others.

An equal split and an unequal split

Worked example

For a 120 bill with 8% tax and 15% tip on the pretax bill, total = 120 + 9.60 + 18 = 147.60. Four equal shares are 36.90. If two people ordered 40 and 80, their proportional shares of that total are 49.20 and 98.40.

Checks and limitations

Agree on whether tip applies before or after tax. Do not add tax a second time to a tax-inclusive bill. For a 100 total split three ways, pay 33.33, 33.33 and 33.34 so the shares sum exactly to 100.
