A tip and tax calculator computes the full restaurant bill in one step: tax on the subtotal, tip on the subtotal, and a per-person split for the table. Enter the pre-tax bill, your local tax rate, your tip percentage, and the number of people, the calculator returns the totals and the share each person owes.

Useful for splitting restaurant tabs without arguing about arithmetic, calculating expense-report totals, planning event catering costs, and any setting where you need bill + tax + tip in one place. The tip in this calculator is computed on the pre-tax subtotal, the etiquette standard in the US.

Key takeaway

Tip on the pre-tax bill, not the post-tax total. US etiquette has been consistent on this point for decades, you're tipping on the food and service, not on the government's portion. Tipping on the post-tax amount is a small but real overspend (about 0.5-2% extra at typical tax rates), and a generous gesture rather than the standard.

How it's calculated

The math:

tax = bill × tax_rate ÷ 100 tip = bill × tip_percent ÷ 100 total = bill + tax + tip per_person = total ÷ people

Both tip and tax are calculated on the pre-tax bill (the "subtotal" line on a US restaurant check). This matches standard US tipping etiquette. If you prefer to tip on the post-tax amount (some do, especially at higher-end restaurants), multiply the tip percentage by (1 + tax_rate/100) to reproduce that calculation.

Standard US tipping percentages:

  • 15%: Acceptable / minimum for adequate service.
  • 18-20%: Standard for good service.
  • 20-25%: Generous; common for excellent service or in high-cost cities where servers depend more on tips.
  • 25%+: Exceptional service or particularly small bills (where a higher percentage compensates for the lower absolute tip).

Outside the US, tipping varies wildly: Japan and South Korea consider tipping rude; most European countries include service in the bill or expect a small 5-10% gesture; Canada and most Latin American countries follow US-style 15-20% norms.

Examples

  1. $60 dinner, 8.25% tax, 20% tip, 2 people

    • Pre-tax bill $60
    • Sales tax rate 8.25%
    • Tip 20%
    • People 2

    A $60 dinner check at 8.25% tax with a 20% tip totals $76.95, or $38.48 per person for a couple. The $4.95 tax on a $60 bill is roughly the combined sales tax in many large Texas cities; the $12 tip is the standard 20% benchmark.

  2. $120 group dinner, 10% tax, 18% tip, 4 people

    • Pre-tax bill $120
    • Sales tax rate 10%
    • Tip 18%
    • People 4

    A $120 group dinner at 10% tax (representative of high-tax cities like Tennessee or Chicago) with an 18% tip totals $153.60, or $38.40 per person split four ways. Note the $12 tax and $21.60 tip, the tip is significantly larger than tax even at the relatively high 10% tax rate, reflecting US tipping norms.

Frequently asked questions

Should I tip on the pre-tax or post-tax amount?

Pre-tax is standard US etiquette. You're tipping on the food and service, not the government's portion. Tipping on post-tax is a small additional gesture but not expected. The math: at typical 8% tax, tipping on post-tax adds roughly 1.5% extra ($1.50 on a $100 dinner). Some upscale establishments or expense-report contexts default to post-tax tipping; ask if uncertain.

How much should I tip?

US norms: 15% adequate, 18-20% standard, 20-25% generous. Below 15% signals dissatisfaction; above 25% is exceptional appreciation. Some major-city restaurants now suggest 20% as the baseline. Counter and takeout: optional, $1-2 per item or a flat 10% if you tip at all. Tip on the pre-tax amount unless you specifically want to add a small gesture on top.

Do I tip on the alcohol portion of a bill?

Yes, generally. Servers handle alcohol orders and often coordinate with the bar. Standard etiquette is to tip on the full pre-tax bill including drinks. The exception is at a sommelier-served high-end restaurant, where you might tip the sommelier separately for wine recommendations and pairing decisions, but the server still gets the standard percentage on the rest of the bill.

How do I split a bill if some people had more expensive items?

Two approaches. Equal split (what this calculator does), sum the bill and divide by people. Simple, builds in some equalization across orders. Itemized split, each person pays for their own items plus their share of tax and tip proportional to their pre-tax subtotal. Itemized is fairer when meal sizes vary widely; equal-split is cleaner socially. Most modern bill-splitting apps do itemized math automatically; for manual splits, equal is forgiving enough to avoid arithmetic arguments.
