Tip Calculator

The bill is here. Everyone is suddenly bad at math. We are not.

Use this free tip calculator to work out the tip amount and total for any bill. Enter the bill and a percentage — 15%, 18%, 20%, or whatever your conscience negotiates — and get both numbers instantly. Splitting? Divide the total by the number of people who actually ate.

Tipping math is not hard; it is just performed under pressure, after wine, with a server standing nearby. We remove the pressure. The wine is on you.

How to Use the Tip Calculator

Inputs:

Bill Amount — the pre-tip total. Tipping on pre-tax vs post-tax is a personal war; the difference on a $60 bill is about $1
Tip % — 15% acceptable, 18% good, 20% standard, 25% "they fixed my order and my mood"

Steps:

Enter the bill amount
Set your tip percentage
Click Calculate to see tip and total
Splitting? Total ÷ number of people. Round up. Nobody has ever respected the person who Venmo-requested $0.37.

How the Calculation Works

Tip = Bill × (Tip% ÷ 100) Total = Bill + Tip

Mental shortcut for 20%: move the decimal one place left (10%) and double it. $47.80 → $4.78 → $9.56
For 15%: take 10%, then add half of that. $47.80 → $4.78 + $2.39 = $7.17
Per person = Total ÷ people. Round each share up to the nearest dollar and the server is happy, the table is happy, the math is done

Worked Example: $86.40 bill, 20%, four people

Tip = 86.40 × 0.20 = $17.28
Total = 86.40 + 17.28 = $103.68
Per person = 103.68 ÷ 4 = $25.92 → call it $26
The person who "just had a salad" still pays $26. That is the price of dining as a group. Order the steak next time.

Tips (From People Who Have Made These Mistakes)

Check whether a service charge or "gratuity included" is already on the bill — common for large parties. Tipping twice is generous, not required
Delivery: tip on the food, not the fees. $3–5 minimum, more in bad weather or for large orders
Bar: $1–2 per drink or 20% on a tab. Bartenders remember
Bad service? 10–15% and a word to the manager beats 0% and silence — 0% mostly punishes the server for the kitchen's mistake

Frequently Asked Questions

How much should I tip at a restaurant?

In the US, 18–20% is standard for table service; 15% is the floor for acceptable service, 25%+ for exceptional. Counter service and takeout are optional, 0–10%.

How do I calculate a 20% tip quickly?

Take 10% (move the decimal one place left) and double it. $54.00 → $5.40 → $10.80. Round to $11 and move on with your evening.

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

Etiquette says pre-tax is fine; most people tip on the total because it is the number on the receipt. On a typical bill the difference is $1–2. Pick one and stop overthinking it.

What is a good tip for delivery?

15–20% of the food cost, with a $3–5 minimum. Apartment stairs, rain, or a 40-pound grocery order justify more. The "delivery fee" almost never goes to the driver.

How do I split a bill with tip?

Calculate the total including tip, then divide by the number of people. For $103.68 among 4: $25.92 each. If orders were very uneven, split by what each person ordered plus a proportional share of tax and tip.

Mini Roast Disclaimer

We roast the number, not you. But if you typed 5%, the calculator noticed, and so did the server.

Reality Check

Tipping norms vary by country and are changing fast — in much of Europe and Asia, 5–10% or nothing is normal, and some US restaurants now build service into prices. When in doubt, look at the local custom, not this calculator. The math is universal; the etiquette is not.
