Splitting a bill should take seconds. Enter the total, pick a tip, and set how many are paying — the calculator handles the tip and the division so nobody has to do mental math at the table.
How the tip is applied
The tip is calculated on the pre-split bill, then the tip and the bill are added together and divided evenly across the party. That matches how most restaurants expect a percentage tip to work.
Tipping norms vary by country and service type. The presets cover common US ranges; adjust to whatever is customary and fair where you are.
A worked example
On an $80 bill with an 18% tip split between two people, the tip is $14.40, the total is $94.40, and each person pays $47.20. Bump the tip to 20% and each share rises to $48. Splitting the total — bill plus tip — rather than just the bill keeps everyone's contribution proportional.
Tip on the pre-tax or post-tax amount?
Etiquette guides differ, but tipping on the pre-tax subtotal is the common baseline — you're rewarding the service, not the sales tax. Plenty of people tip on the total for simplicity, especially where tax is low, and either is fine.
For larger groups, check the bill first: many restaurants add an automatic gratuity of 18–20% for parties above a certain size, in which case you shouldn't tip again on top. When in doubt, ask — it's a common enough question that staff won't blink.
