Gratuity Calculator
Gratuity and tip mean the same thing in everyday speech. The distinction that matters is whether the amount is yours to choose — and there is an actual test for that, not just an opinion.

If your bill already shows an automatic gratuity, you have paid it. Use the calculator to check what percentage was applied rather than to add a second one.
Is Gratuity the Same as a Tip?
In ordinary conversation, yes. Gratuity is the formal word — it appears on receipts, in contracts and in restaurant policies, while people say tip out loud. Both mean money paid for service on top of the price of the goods.
The distinction that actually matters is not linguistic. It is whether you were free to choose the amount. A payment you decided on is a tip. A percentage the restaurant added before handing you the bill is a service charge, even when the receipt calls it a gratuity.
That is not a matter of opinion — the IRS publishes a four-part test for it, and the answer changes how the money is taxed, who has to receive it, and whether you can decline it.
The Four-Factor Test for What Counts as a Tip
IRS Revenue Ruling 2012-18 sets out four factors. The absence of any one of them casts doubt on whether a payment is a tip and indicates it may be a service charge instead. All the surrounding facts are considered together.
| Factor | What it means in practice |
|---|---|
| The payment is made free from compulsion | You could have left the tip line blank |
| The customer has an unrestricted right to determine the amount | You picked the number, not the restaurant |
| The payment is not negotiated or dictated by employer policy | It is not set by a policy printed on the menu |
| The customer generally decides who receives it | You can direct it to the person who served you |
Run an 18% automatic gratuity on a party of eight through that list and it fails the first three factors outright. This is why the IRS treats it as a service charge — not because of what the receipt calls it, but because you did not choose it.
Why the Classification Changes Things
The label is not bureaucratic housekeeping. Three practical consequences follow from it.
What changes when a payment is a service charge rather than a tip:
- How it is taxed. A service charge distributed to employees is paid as regular wages rather than as tip income, which changes reporting for both the worker and the employer.
- Who decides where it goes. A tip belongs to the employee. A service charge is business revenue, and the business decides how much of it, if any, reaches staff.
- Whether you can decline it. A tip is always optional. A service charge disclosed before you ordered is part of the agreed price of the meal.
That second point is the one worth remembering as a customer. Money the restaurant collects as a service charge does not automatically reach your server, however the receipt describes it.
Automatic Gratuity for Large Parties
Most American restaurants add a gratuity automatically once a party reaches a certain size — commonly six or eight people — at a rate usually between 18% and 20%, though the range in practice runs from about 15% to 22%. The threshold and the percentage should be printed on the menu.
The reasoning is practical. A large table occupies a server for the whole evening, replaces several smaller tables they would otherwise have turned over, and historically produced worse tips per head because everyone assumed someone else was covering it.
Most point-of-sale systems calculate the charge on the pre-tax subtotal by default, which matches the convention for voluntary tips.
Where automatic gratuity commonly appears:
- Parties of six or more — 18–20%, disclosed on the menu.
- Private dining and events — often 20–22%, written into the contract.
- Resort and hotel spas — 18–22% added to every treatment.
- Cruise ships — a flat daily rate per passenger, plus 18–20% on drinks.
- Room service — a delivery charge and a gratuity, sometimes both.
- Tourist-area restaurants — occasionally applied to all tables.
Do You Tip on Top of an Automatic Gratuity?
No. The automatic charge is the tip, and adding a full second one means paying roughly double.
This is the most expensive mistake on the whole subject and it is easy to make, because the card terminal will still offer you a tip line afterwards. On a $400 bill for eight people that already includes $72 of automatic gratuity, accepting a 20% suggestion at the terminal takes the total to about 38%.
The habit that prevents it is simple: read the bottom of the itemised bill before you look at the tip line. If a line says gratuity, service charge, or a percentage you did not choose, you have already tipped.
Adding a small extra amount for genuinely outstanding service is a normal gesture. Adding a second full percentage is not, and no server expects it.
Can You Refuse an Automatic Gratuity?
It depends entirely on whether it was disclosed before you ordered.
Where it was printed on the menu you ordered from, the charge is part of the agreed price of the meal, in the same way a corkage fee is. Restaurants can and do enforce it.
Where it was not disclosed anywhere — nothing on the menu, nothing on the website, appearing for the first time on the final bill — it is a term you never agreed to. Raising it politely with the manager almost always gets it removed.
In practice most restaurants will adjust or remove an automatic gratuity if the service genuinely failed. Ask calmly rather than refusing to pay: the server is rarely the person who set the policy, and they are the one who loses if the charge is voided.
Service Charge, Gratuity, and What Actually Reaches Staff
A third term now appears on bills increasingly often: the plain service charge. A restaurant adding a 5% kitchen appreciation fee, a 3% wellness surcharge, or a flat service charge in place of tipping is not collecting a tip on your behalf.
That money is business revenue. The business decides where it goes — it may pass to staff in full, be split with the house, or fund benefits and kitchen wages. Your server may see none of it.
If a restaurant has adopted a service-included model and says so clearly, an additional tip is genuinely optional; that is the entire point of the model. If it has simply added a surcharge alongside a normal tip line, tipping normally on the subtotal remains the right move.
The only method that guarantees money reaches the person who served you is cash handed to them directly. Everything routed through the business is subject to the business's policy.
How Much Gratuity Is Normal
For United States table service, 18–20% is the current default and 15% is the acceptable floor. That figure has moved upward over time, from 10% in the early twentieth century to 15% through the 1980s and 1990s.
For catering and private events, contracts typically specify 20–22%. Read whether that figure is described as a gratuity going to staff or a service charge retained by the venue — the two are often listed separately, and some contracts include both.
Where an event contract already includes a gratuity, an additional cash tip to the specific people who ran the evening is a normal gesture rather than an expectation.
Common Mistakes
Five things go wrong repeatedly with gratuity, and all of them cost money.
What to watch for:
- Tipping on top of an automatic gratuity. Check the itemised bill before the tip line, not after.
- Assuming a service charge reaches your server. It is business revenue; the business decides.
- Treating the terminal's suggestion as the bill's percentage. Card terminals calculate from the post-tax total, so a 20% button is closer to 21.6% of the subtotal at an 8% tax rate.
- Paying an undisclosed charge without asking. If it appeared for the first time on the final bill, ask.
- Voiding a charge to punish the restaurant. The server usually absorbs the loss, not the owner.
Gratuity at Common Percentages
What an automatic gratuity comes to on the bill sizes where it usually appears.
| Bill | 18% | 20% | 22% | Total at 20% |
|---|---|---|---|---|
| $150 | $27.00 | $30.00 | $33.00 | $180.00 |
| $200 | $36.00 | $40.00 | $44.00 | $240.00 |
| $300 | $54.00 | $60.00 | $66.00 | $360.00 |
| $400 | $72.00 | $80.00 | $88.00 | $480.00 |
| $500 | $90.00 | $100.00 | $110.00 | $600.00 |
| $750 | $135.00 | $150.00 | $165.00 | $900.00 |
| $1,000 | $180.00 | $200.00 | $220.00 | $1,200.00 |
| $2,500 (event) | $450.00 | $500.00 | $550.00 | $3,000.00 |
Check whether the percentage on your bill is described as a gratuity or a service charge. Under the IRS test both are service charges if you did not choose the amount, but the wording tells you what the restaurant intends to do with it.

Frequently Asked Questions
Is gratuity the same as a tip?
In everyday use yes — gratuity is the formal word for a tip. In tax terms they differ: a payment only counts as a tip if you chose the amount freely, which an automatic gratuity does not.
How does the IRS decide whether something is a tip?
Revenue Ruling 2012-18 sets four factors: the payment is free from compulsion, you have an unrestricted right to set the amount, it is not dictated by employer policy, and you generally decide who receives it. Missing any of them points to a service charge.
How much gratuity should I leave?
Eighteen to twenty percent for US table service, with 15% the acceptable floor. Catering and private event contracts usually specify 20 to 22%.
What is automatic gratuity?
A fixed percentage — usually 18 to 20% — added to the bill by the restaurant, most often for parties of six or more. It should be disclosed on the menu before you order.
Do I tip on top of automatic gratuity?
No. The automatic charge is the tip. Adding a full second percentage on a $400 bill can take the total to around 38%.
Can I refuse to pay an automatic gratuity?
If it was disclosed on the menu before you ordered, it is part of the agreed price and restaurants can enforce it. If it appeared without any prior notice, asking the manager to remove it is reasonable.
What is the difference between a service charge and a gratuity?
A gratuity is intended for staff. A service charge is revenue belonging to the business, which decides how it is used — your server may receive none of it.
Is automatic gratuity taxed differently?
Yes. Because it fails the IRS test for a tip, it is treated as a service charge and paid to employees as regular wages rather than as tip income.
Does automatic gratuity go to my server?
Not necessarily in full. As a service charge it is business revenue, and the restaurant decides how much reaches staff. Cash handed over directly is the only method that guarantees it.
Is gratuity calculated before or after tax?
Most point-of-sale systems apply it to the pre-tax subtotal by default, matching the convention for voluntary tips.
What is the average gratuity percentage?
Around 19% for US restaurant table service, up from 15% in the 1990s. See the average tip percentage page for the survey and card data behind that figure.
