Tip Calculator | Free Gratuity & Bill Split Tool
Calculate the perfect tip for any service. Rate service quality, split the bill with friends, include sales tax, and compare 15%, 18%, and 20% tips side by side.
What is Tip Percentage and Why It Matters
Tip percentage is the portion of your bill (usually calculated on the pre-tax amount) that you give to a service worker as a thank-you for good service. It's expressed as a percentage of the total — for example, a 20% tip on a $50 bill means you leave $10 extra, paying $60 total.
Tipping matters because in many countries — especially the United States — service workers rely on tips as a significant part of their income. Standard tipping ranges from 15% to 25%, with the exact amount depending on the quality of service, the type of establishment, and local customs. Understanding tip percentages helps you budget accurately and show appropriate appreciation.
The Tip Formula
The basic formula for calculating a tip is straightforward. Use our tip calculator above for instant results, or apply the formula manually:
Tip Amount = Bill Amount × (Tip Percentage ÷ 100)
For example, on a $80 bill:
15% tip: $80 × 0.15 = $12.00 → Total: $92.00
18% tip: $80 × 0.18 = $14.40 → Total: $94.40
20% tip: $80 × 0.20 = $16.00 → Total: $96.00
25% tip: $80 × 0.25 = $20.00 → Total: $100.00
How to Calculate Tip in Your Head
You don't always need a calculator to figure out a good tip. These mental math tricks work for any bill amount:
10% — The Foundation
Move the decimal point one place left. For a $67 bill, 10% = $6.70. This is the building block for all other percentages.
15% — Add Half of 10%
Calculate 10%, then add half. $6.70 + $3.35 = $10.05. Or round 10% up and subtract a bit: $6.70 + $3.40 ≈ $10.10.
20% — Double the 10%
Calculate 10% and double it. $6.70 × 2 = $13.40. Easy and fast — this is the most popular tip amount.
25% — 20% + Half of 10%
Calculate 20% (double 10%), then add half of 10%. $13.40 + $3.35 = $16.75. Great for excellent service.
18% — The Middle Ground
Add 10% + 5% + 3%. $6.70 + $3.35 + $2.01 = $12.06. Or: 20% minus 2% (which is ⅕ of 10%).
Quick Shortcut
For a quick approximation: just move the decimal and round. $48.50 bill → ~$5 → $10 tip (≈20%). Close enough for most situations.

Common Tip Percentages by Service Type
Different services call for different tip amounts. Here's a quick reference.
| Service Type | Standard Tip % | Example on $50 Bill |
|---|---|---|
| 🍽️ Sit-Down Restaurant | 15-20% | $7.50 - $10.00 |
| 🍸 Bar / Bartender | 15-20% or $1-2/drink | $7.50 - $10.00 tab; $1 beer, $2 cocktail |

Splitting the Bill Evenly
Splitting the bill with friends or family is easier than you think — even with tip and tax included. Here's the simple formula:
Each Person Pays = (Bill + Tip + Tax) ÷ Number of People
Quick Example
$120 bill, 20% tip ($24), 8% tax ($9.60). Total: $153.60 ÷ 4 people = $38.40 each.
Unequal Orders
If someone ordered more, have them cover the difference. One person pays $30 of food, another $60 — then split the tip and tax proportionally or evenly.
Pro Tip: Use Our Calculator
Our bill splitter above handles all the math. Just enter the bill, set the tip percentage, and adjust the split count — we'll calculate the exact amount each person owes, including tax.
Common Tip Calculation Mistakes
Mistake 1: Tipping on the Tax-Included Total
Most etiquette guides recommend tipping on the pre-tax bill. On a $100 pre-tax bill with 8% tax ($108 total), tipping 20% on $108 ($21.60) instead of $100 ($20.00) costs you $1.60 extra per meal — that's $83/year if you dine out once a week.
Mistake 2: Forgetting to Tip on Discounted Bills
When you use a coupon or Groupon, tip on the full pre-discount price. The server did the same work regardless of your discount. A 50% off coupon on a $60 meal means you paid $30 — but tip on $60, not $30.
Mistake 3: Rounding Down Instead of Up
Your bill is $47.50 and you want to leave 20%. Instead of calculating $9.50 and leaving $10, some people round down to $8 or $9. Always round up — the difference is pennies to you but meaningful to the server.
Mistake 4: Not Checking for Auto-Gratuity
Many restaurants add an automatic 18-20% gratuity for parties of 6 or more. Always check your bill before adding an extra tip — you could be double-tipping without realizing it.

| 🍸 Bartender | $1-2 per drink or 15-20% of tab | $1 for beer/wine, $2 for cocktails |

| 🎩 Concierge | $5-20 | $5 for simple, $10-20 for hard-to-get reservations |

Tip vs Service Charge vs Gratuity: What's the Difference?
💵 Tip
A voluntary payment given directly to a service worker for good service. Amount is at your discretion — typically 15-20% of the bill.
📋 Service Charge
A mandatory fee added to your bill by the establishment (common for large groups of 6+). This is not optional and may or may not go to the server.
📜 Gratuity
Another word for tip. "Gratuity" comes from the Latin word for "gift" or "favor." In some contexts, a gratuity is automatically included (e.g., cruise ship gratuities, large party auto-gratuity).
Easy Ways to Calculate a Tip Without a Calculator
10% — The Base
Move the decimal point one place left. For an $85 bill, 10% = $8.50. This is the foundation for all other tip percentages.
15% — 10% + Half of 10%
Calculate 10%, then add half of that. $8.50 + $4.25 = $12.75 tip on an $85 bill. Use our tip calculator for exact amounts.
20% — Double the 10%
Calculate 10% and double it. $8.50 × 2 = $17.00 tip on an $85 bill. Use the "Excellent" quality setting in our calculator above.

Should I tip on takeout orders?
Tipping 10-15% on takeout orders is a nice gesture, especially if there was special preparation or packaging involved. While not as expected as dine-in tipping, it's appreciated.

Both are perfectly fine. Cash tips are preferred by many servers since they receive them immediately, but credit card tips are recorded and taxed. Either way, the server appreciates it.
