Tip & Bill Splitter

What's customary, and where it varies

Tipping is a cultural convention, not a fixed rule, and the 'normal' amount swings wildly by country. In the United States, table service is typically tipped 15-20% of the pre-tax bill, and servers are often paid a tipped-minimum wage that assumes those tips. Across much of continental Europe a service charge is frequently already included (look for 'service compris' or a line on the bill), and rounding up or leaving 5-10% is generous rather than expected. In Japan tipping is not customary at all and can cause confusion. This tool does the arithmetic; the percentage you choose is a social decision only you can make.

Context shifts the norm even within one country: counter service, takeaway and a tap-to-pay screen prompting 20% are not the same as full table service, and a large group is often subject to an automatic 'gratuity' the venue adds itself. Always check whether a service charge or auto-gratuity is already on the bill before adding more — paying a percentage twice is the most common tipping mistake.

Splitting evenly versus splitting by item

An even split divides the grand total by the number of people — fast, friendly, and fair when everyone ate and drank roughly the same. It stops being fair the moment one person had a three-course meal and a bottle of wine while another had a salad and tap water. Splitting by item assigns each line to whoever ordered it, then distributes tax and tip proportionally to each person's subtotal. It's more work but it's the honest answer for mismatched orders, and it's the right approach when one diner isn't drinking alcohol that's inflating the bill.

A practical middle path: split shared plates and the table's wine evenly, but keep clearly individual big-ticket items (the steak, the cocktails) on the person who ordered them. Whatever method you pick, agree it before the bill arrives — renegotiating a split at the table is where evenings sour.

Tax, rounding, and tip-before-or-after

• Tip on pre-tax or post-tax? Etiquette guides traditionally say tip on the pre-tax subtotal, since tax isn't the server's work; many people tip on the post-tax total for simplicity. On a 20% tip the gap is small but real — on a $100 meal with 10% tax, post-tax tipping costs about $2 more.
• Rounding is where splits leak cents: $100.00 split three ways is $33.33 each with a cent left over. Round each share up to the nearest cent or dollar and let one person absorb the rounding, or the total collected won't match the bill.
• Watch for a pre-added service charge or 'large party' gratuity already on the receipt — adding your own percentage on top double-tips.
• A 'suggested tip' printed on the receipt is sometimes calculated on the post-tax total, which quietly nudges the amount up. Verify the base it used before tapping the button.

What this calculator is — and isn't

This is a bill-splitting calculator, not financial or tax advice, and not a statement about what you 'should' tip. It takes a total, a percentage and a headcount and returns clean per-person figures so nobody at the table has to do mental math. For longer multi-step sums use the plain Calculator; for issuing an itemised bill to a client rather than splitting a restaurant tab, the Invoice Generator is the right tool.
