How It Works

Dividing a check among a group is one of those small tasks that turns awkward fast, and a quick calculation settles it before anyone reaches for their phone. Whether it is a dinner out, a shared trip, or the monthly household bills, working out each person's fair share keeps the math honest and the conversation easy.

This calculator asks for the bill before tip and tax, the number of people, a tip percentage and a tax percentage. The tip and the tax are both worked out on the pre-tax bill and added to it, and the grand total is divided evenly. In Custom Amounts mode you enter each person's own subtotal instead, separated by commas, and each person pays that amount plus a matching share of the tip and tax.

Enter the bill before tax and tip, since the calculator adds both for you; if the figure you have already includes them, set the tip and tax fields to 0. Confirm the headcount so nobody is over- or undercharged, and when one person ordered something separately, use Custom Amounts so that item isn't spread across the whole group. In that mode, make the amounts add up to the bill, because each share is built from what you type.

Example: Dinner for Four with Tip and Tax

1 Input: Total Bill (before tip & tax) $120, Number of People 4, Tip 18%, Tax 8%, Equal Split.
2 Tip: 18% × $120 = $21.60. Tax: 8% × $120 = $9.60. Grand total: $120 + $21.60 + $9.60 = $151.20.
3 Equal split: $151.20 / 4 = $37.80 each, made up of $30.00 of food, $5.40 of tip and $2.40 of tax.
4 Custom Amounts 40, 35, 25, 20: the person with the $40 subtotal pays $40 + $7.20 tip + $3.20 tax = $50.40, and the others pay $44.10, $31.50 and $25.20, which again add up to $151.20.

Frequently Asked Questions

How do I split a restaurant bill fairly with tip?

Add the food subtotal plus tax, then calculate the tip on the pre-tax amount (15-20%). Divide the total (food + tax + tip) by the number of people. For unequal orders, each person pays their items plus a proportional share of tax and tip.

Should you tip on the pre-tax or post-tax amount?

Etiquette guides recommend tipping on the pre-tax subtotal. However, the difference is small. On a $100 meal with 8% tax, tipping 20% pre-tax is $20 versus $21.60 post-tax. Most servers appreciate either approach.

What is the standard tip percentage in the US?

The Emily Post Institute's tipping guide lists 15-20% of the pre-tax bill for sit-down restaurant service and 10% at a buffet, and says tip jars at a counter carry no obligation. This calculator's tip field starts at 18%.
