Tip Calculator for Groups

The Tip Problem at Group Dinners

Calculating tip is straightforward when you are dining alone. Take the subtotal, multiply by your tip percentage, and you are done. But add a few friends to the table and things get complicated fast.

The most common approach is to divide the total tip evenly among everyone. But is that really fair? If you ordered a $12 pasta and your friend had a $45 surf-and-turf, should you each pay the same amount of tip? Most people would say no, but doing the proportional math at the table is a headache nobody wants.

That is where Jig comes in. When you split a receipt with Jig, tip is automatically distributed proportionally based on what each person ordered. No manual calculation needed.

How Jig Calculates Tip Per Person

Jig uses proportional tip distribution, which is the fairest method for groups. Here is how it works:

1. Calculate each person's subtotal. Jig adds up the items assigned to each person. Shared items are divided among the people who shared them.
2. Determine each person's share of the bill. Each person's subtotal is divided by the group subtotal to get their percentage of the total bill.
3. Apply that percentage to the tip. Each person pays that same percentage of the total tip amount. The person who spent the most pays the most tip, proportionally.

The Math Behind Fair Tip Splitting

Here is a concrete example to show how proportional tip distribution works:

Jig applies this same logic to tax as well, so both tax and tip are distributed fairly based on what each person actually ordered.

Common Tip Percentages

Not sure what percentage to tip? Here are the standard tipping guidelines for restaurants in the United States:

When splitting with Jig, you can enter any tip amount — either as a dollar value already on the receipt or as a custom amount. Jig handles the per-person distribution from there.

Why Proportional Tip Matters

Splitting tip evenly might seem simpler, but it creates an unfair dynamic, especially in groups with very different spending. The person who ordered the least effectively subsidizes the tip for the person who ordered the most. Over time, this can lead to resentment or people avoiding group dinners altogether.

Proportional tip distribution solves this by linking each person's tip to their own spending. It is the same principle that restaurants use when they add an automatic gratuity to large parties — the tip is based on the total check, and each diner contributes proportionally.

Jig automates this so you never have to think about the math. Just split the receipt and the tip calculation is handled for you.

More Than Just a Tip Calculator

Jig is not just a tip calculator — it is a complete bill splitting tool that handles every part of dividing a receipt. AI reads the receipt, you assign items to people, and Jig calculates everything including tax, tip, and per-person totals. Then you share the split with your group and settle up through Venmo.

Whether you are splitting a restaurant bill, a grocery receipt, or travel expenses, Jig makes the process fast and fair.
