How to Split the Bill at a Birthday Dinner

When friends take someone out for their birthday, the group covers the guest of honor. Their dinner, their drink, their dessert with a candle in it: all of it is shared between the people paying.

The awkward part is never the rule. It's the math at the end of the night, when one person has put an eight-person bill on their card and someone says “let's just split it evenly” while the friend who had a salad goes quiet.

If the birthday person organized their own dinner and invited everyone, it's normal for each person to pay their own way. Say which kind of dinner it is in the invite, and nobody has to guess.

Five friends go out for Maya's birthday in New York. The table shares a burrata, everyone orders a main, and Maya gets a tiramisu with a candle. Ana puts the bill on her card.

Maya's risotto and tiramisu, and the burrata everyone shared, come to $50.00 before tax and tip. Split four ways, that's $12.50 each. Each friend adds it to their own main, and tax and tip are shared in proportion to what each person's part of the food costs:

Chloe's short rib cost almost twice Ana's pizza, so she pays more. That's the whole point of splitting by item: the birthday gift is shared equally, and the dinner is paid for by whoever ate it.

If everyone ordered roughly the same, skip the itemizing and divide the total by the number of people paying, not the number of people at the table. Here that's $197.18 ÷ 4 = $49.30 each.

It's fast and it's fine for a table that orders alike. At this table it would have Ana paying $9.99 more than the itemized split and Chloe $10.63 less, which is the argument itemizing avoids. If some people aren't drinking, see splitting with non-drinkers.

1. Snap the receipt. The organizer takes a photo, tidytab reads each line and the tax, and you add the tip you left.
2. Choose how people pay. “Pick dishes” for the itemized split above, or “Split evenly” with the number of people set to the ones paying (you included, the birthday person left out).
3. Share one link in the group chat, and don't send it to the birthday person.
4. Each friend taps their own main, then taps each of the birthday person's dishes and the shared plates and picks their portion (a quarter here, for four people paying). tidytab adds their part of the tax and tip.
5. Everyone pays you with Venmo, Zelle, Cash App, PayPal or a bank transfer, and the page shows who has paid and what is still outstanding.

If one friend would rather treat the birthday person on their own, use “Split evenly” with the birthday person counted in the number of people. That friend chooses to pay for two and names who they're covering.

• Say it in the invite. “We're treating Maya, so we'll split her share” saves the conversation at the table.
• Ask for one check before ordering. Splitting a large table into separate checks at the end is slow for everyone, the server included.
• Check for an included service charge. Many restaurants add a gratuity for larger parties. If it's on the receipt, don't tip again on top of it.
• Settle the same night. People pay while they still remember the dinner. A week later it's a favor you're asking for.
