Tipping is a core part of dining culture in the United States, where 15–20% is standard for restaurant service. But calculating the exact tip—and splitting it among a group—can be surprisingly tricky, especially after a few drinks.
Enter the bill total, select your tip percentage, and specify how many people are splitting. You'll see the tip amount, total bill with tip, and each person's share together. No more awkward math at the table.
Whether you're dining out with friends, calculating tips for delivery, or figuring out gratuity for a large group (where 18–20% automatic gratuity often applies), this calculator helps everyone settle the bill fairly.
Quick tipping math eliminates awkward bill-splitting moments. This calculator shows the tip amount, total with tip, and per-person cost together, making group dining stress-free and ensuring your server gets a fair gratuity.
Tip = Bill × (Tip Percentage / 100)
Total = Bill + Tip
Per Person = Total / Number of PeopleResult: $37.35 per person
Tip: $124.50 × 20% = $24.90. Total bill: $124.50 + $24.90 = $149.40. Split 4 ways: $149.40 ÷ 4 = $37.35 per person. Each person pays $37.35, which includes $6.23 in tip.
Tipping in the US is fundamental because servers earn a lower tipped minimum wage ($2.13/hr federally). Tips typically represent 60–80% of a server's income. The cultural standard has shifted from 15% to 18–20% as the baseline for acceptable service.
Consider tipping above 20% for: exceptional service, complex orders (dietary accommodations, large groups), holiday dining, or when the service clearly went above and beyond. For counter service and coffee shops, $1–2 per order or 10–15% is a kind gesture.
Tipping norms vary globally. In Japan, tipping is considered rude. In most of Europe, a 5–10% tip is generous (servers earn a full wage). In the US, 15–20% is essential. Always research local customs when traveling.

Standard tipping in the US is 15–20% for sit-down restaurants. 15% is acceptable for adequate service, 18% for good service, and 20%+ for excellent service. Anything below 15% signals dissatisfaction with service specifically.
Etiquette experts recommend tipping on the pre-tax subtotal. However, many people tip on the post-tax total for simplicity. The difference is usually small (1–2%), so either approach is acceptable.
Tip delivery drivers 15–20% or $5, whichever is greater. For large or difficult orders (heavy items, stairs, bad weather), tip more. Many delivery apps suggest 15–25% as default options.
Tipping on takeout is optional but increasingly common. 10–15% is a kind gesture, especially for complex orders. During the pandemic, tipping on takeout became more normalized, and many restaurants appreciate it.
Many restaurants add 18–20% automatic gratuity for parties of 6–8 or more. This is legal and customary. You can add extra on top for exceptional service, but you're not expected to. Always check the bill before adding more tip.
The simplest method is splitting the total (bill + tip) equally. If diners ordered vastly different amounts, calculate each person's share of the bill, then add their proportional tip on top. Apps and this calculator make both methods easy.
