How do I split a bill with tip included?

Add the tip to the total bill, then divide by the number of people. For a $90 bill with an $18 tip split three ways: ($90 + $18) / 3 = $36 per person. Toolin's calculator does this automatically when you enter the bill, tip percentage, and number of people.

What if someone did not eat as much as everyone else?

For fairness, you can split by item instead of evenly. Have each person add up what they ordered, then split shared items (like appetizers) and the tip evenly. Toolin's calculator handles the even-split scenario; for itemized splits, tally individual totals manually.

Should tax be included before or after splitting?

Include tax in the total before splitting. Tax is part of the bill that everyone owes, so it should be divided equally along with the food and tip. Use the final receipt total, not the subtotal.

The Basic Even Split

The simplest approach is to divide the total bill (including tax and tip) by the number of people. For a $120 bill with a $20 tip split four ways, each person pays ($120 + $20) / 4 = $35. This works well when everyone ordered similarly priced items. If the group prefers to split before tip, calculate each person's share of the subtotal first, then add individual tips.

Step-by-Step Split with Tip

Start with the total bill

Get the final amount from the receipt, including tax.

Add the tip

Calculate the tip on the pre-tax subtotal and add it to the total. For example, 18% on a $100 subtotal is $18.

Divide by the number of people

Split the grand total (bill + tip) equally. Round up to the nearest cent or dollar for simplicity.

Handle the rounding difference

If rounding creates a small shortfall, one person covers the extra cent or two. Or round everyone up slightly and leave the extra as additional tip.

Tips for Fair Splitting

Agree on the splitting method before ordering to avoid surprises.
Use the even split when everyone ordered in a similar price range.
For big price differences, consider splitting by item instead of evenly.
Account for people who only had drinks or appetizers.
Include tax and tip in the split so the server is not short-changed.
