Tip Calculator

Tip amount, total bill and the split per person.

How it works

This calculator takes three pieces of information—your bill total, the tip percentage you want to leave, and how many people are sharing the cost—and instantly tells you the tip amount, final total, and what each person owes.

It's useful at restaurants, cafes, hair salons, or anywhere you're splitting a bill with others and want to include gratuity. Instead of doing mental math or pulling out your phone for a separate app, you get all three numbers at once.

The formula

Tip = Bill × (Tip % ÷ 100); Total = Bill + Tip; Per Person = Total ÷ Number of People

Worked example

Imagine you and two friends have lunch at a restaurant. The bill comes to $87.50. You want to tip 18%, and you're splitting it three ways.

Step 1: Calculate the tip amount

  • Tip % = 18
  • Bill = $87.50
  • Tip = $87.50 × (18 ÷ 100) = $87.50 × 0.18 = $15.75

Step 2: Find the total bill

  • Total = $87.50 + $15.75 = $103.25

Step 3: Divide by number of people

  • Per person = $103.25 ÷ 3 = $34.42 (rounded)

So each person pays $34.42, which includes their share of the meal and the tip.

Why these numbers matter

The tip percentage varies by context and region. In the United States, 15–20% is standard for sit-down restaurants; 18% is a reasonable middle ground. For takeout, 10–15% is common. Coffee shops often suggest 15–20%. Delivery services typically expect 15–18%.

If you're unsure, 18% is a safe, generous default that covers good service without being excessive.

Common mistakes

Tipping on the pre-tax bill vs. post-tax bill
Some people calculate the tip on the subtotal (before tax), others on the total (after tax). Both are acceptable, but tipping on the post-tax total is more common in North America and typically what most people expect. Check your local custom.

Forgetting to include tax in the total
When splitting, make sure you're dividing the final amount including tax and tip. The calculator handles this automatically, but if you're doing it by hand, it's easy to miss.

Rounding confusion
When three or more people split a bill, the per-person amount often has cents that don't divide evenly. One person may pay a few cents more or less. The calculator rounds to the nearest cent, which is standard; just be aware someone might owe $34.42 while another owes $34.41.

Not accounting for different consumption
This calculator assumes everyone pays equally. If one person ordered much more or drank more, you might want to adjust the split manually—some people calculate each person's individual bill plus their portion of shared items (like appetizers) before adding a shared tip.

Tips for real-world use

  • Know the local norm. Tipping expectations vary widely by country and industry. In some parts of Europe, 5–10% is standard; in the US, 18–20% is expected.
  • Round generously. If the math lands on $34.417 per person, rounding up to $34.42 is kind to the server.
  • Adjust for service. This calculator uses whatever percentage you enter. If service was exceptional, bump it to 20%. If it was poor, 10–12% is still acceptable in most places.
  • Use it before you go. Calculate at home or on the way to the restaurant so you know your budget and can pay quickly without holding up others.
  • Consider cash vs. card. Some restaurants add automatic gratuity for larger groups; check your receipt before adding extra tip to avoid double-tipping.

Frequently asked questions

What's a standard tip percentage?

In the United States, 15–20% is standard for table service; 18% is a reasonable middle ground. Takeout and delivery typically receive 10–15%. Practices vary significantly by country—check local norms where you are.

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

Tipping on the post-tax total (the amount you actually pay) is most common in North America. Some people prefer to tip on the subtotal, which is also acceptable. Either way, the difference is usually small.

What if the split doesn't divide evenly?

The calculator rounds to the nearest cent. In practice, one or two people may pay a penny or two more or less. Round up slightly if you want to be generous, or one person can cover the rounding difference.

Can I use this for other services (haircuts, delivery, etc.)?

Yes. Enter the service cost as the bill, choose your tip percentage (typically 15–20% for personal services, 15–18% for delivery), and use the tip amount. You don't need to split unless multiple people are sharing the cost.

Does this calculator include tax?

You enter the bill amount as it appears on the receipt (usually including tax). The calculator then adds your chosen tip percentage to that total. If you want to tip only on the pre-tax subtotal, enter that amount instead.

What if one person ordered much more than others?

This calculator splits equally. For unequal consumption, calculate each person's individual bill first, then add a shared tip (or each person tips on their own portion). Some groups use separate checks to avoid this complexity.
