How it is calculated
Tip on the pre-tax amount if the receipt separates them. Tipping on the tax-inclusive total quietly adds a few percent that nobody intended, and on a large bill that is real money. Where tax is already baked into the listed price, the distinction disappears.
Rounding up leaves a surplus, and the surplus grows with the group. Five people rounded up to the nearest unit can leave several units on the table. That is usually fine — it lands with the person who fronted the bill — but it is worth seeing the number before agreeing to it.
The payer is also one of the diners. With five people the payer is owed four shares, not five. This calculator works it out that way, which is the part people most often get wrong when settling up in a hurry.
Frequently asked questions
Should I tip on the pre-tax or post-tax total?
Pre-tax is the convention where tax is listed separately. Tipping on the post-tax figure quietly raises the effective rate by whatever the tax rate is.
What happens to the rounding surplus?
It goes to whoever paid the bill. If that feels uneven, choose a smaller rounding step — the surplus shrinks with it.
What if people ordered very differently?
This splits evenly. When orders differ a lot, total each person separately and use this only for shared items and the tip.
A plain even-split calculation. It does not handle differing individual orders or discounts applied to only part of the bill.
