Pre-tax or post-tax?

Strict etiquette says tip on the pre-tax subtotal; in practice most people tip on the final number because it's the one printed biggest. On a typical 8–10% sales tax the difference at 18% is small — about $1.50 on a $100 bill — so pick one rule and stop doing arithmetic at the table.

The round-up option

Ticking "round up" nudges each person's share to the next whole unit and shows the effective tip percentage you'd land on. It usually adds cents per head, kills the awkward coin-shuffling, and servers appreciate the difference.

Splitting fairly vs splitting simply

Equal splits are the social default and this calculator's job. If one person had three cocktails and another had soup, equal splitting taxes the soup — for those groups, split the items first and tip individually. Everything in between: split evenly and rotate who "wins" over time.

Frequently asked questions

Should I tip on the pre-tax or post-tax amount?
Etiquette guides say pre-tax; most people use the after-tax total for simplicity. At 18% the gap is roughly $1.50 per $100 of bill in a 9% tax state — negligible for a group, so just be consistent.
What is a standard tip in the US?
18–20% at sit-down restaurants is today's norm; 15% reads as below-average service. Counter service and takeout are genuinely optional (0–10%).
How does the round-up option work?
It rounds each person's equal share up to the next whole currency unit, then reports the effective tip % that produces. It typically adds only cents per person while making the payment trivially easy.
Is service charge the same as a tip?
No. A mandatory 'service charge' (common for large parties, 18–20%) legally belongs to the house, though most pass it to staff. If it's on the bill, you're not expected to tip on top — adding a small extra for great service is optional.
Do other countries tip like the US?
No — the US is the outlier. Canada is similar; the UK ~10% where no service charge applies; much of Europe rounds up modestly; Japan and South Korea don't tip at all and may refuse it.
