Figuring out a tip should not require a pencil, a phone calculator, or an awkward pause at the table. This tip calculator does the math instantly: enter your restaurant bill, choose a tip percentage, and it shows the tip amount, the total bill, and — if you are sharing — exactly what each person owes. Whether you are grabbing dinner with one friend, splitting a check among four coworkers, or deciding how much to leave for room service, the numbers update as you type so there is no guessing when the card arrives.
No account, no ads to wade through, and no rounding surprises. You see the raw tip, the rounded-up total, and the per-person share side by side.
How to Use
- Enter the Bill Amount — the pre-tip total on your check, usually including food, drinks, and tax. If your server added an automatic gratuity already, subtract it first so you are not tipping twice.
- Set the Tip Percentage. The default is 15%, but you can slide it anywhere from 0% to 100%. A quick guide: 15% is standard for average-to-good service, 18–20% for attentive sit-down service, and 10% or less for slow or careless service.
- Set People Sharing to 1 if you are paying alone, or to the number of people splitting the bill. The calculator divides the total (including tip) evenly, so nobody has to do the division in their head.
- Read the result card: Tip Amount shows what you leave on the table, Total Bill (with Tip) shows the full amount charged, and Each Person Pays shows the fair split.
The math behind it is straightforward: the tip is the bill times the percentage divided by 100, the total is the bill plus the tip, and each person's share is the total divided by the number of people. Because every figure is shown to two decimal places, you can hand the server a whole number without shortchanging anyone.
How Much Should You Tip?
Tipping customs depend heavily on where you are, but in the United States the norm for full-service restaurants is firmly in the 15–20% range. Many servers earn a sub-minimum "tipped" wage, so the tip is not an extra bonus — it is the bulk of their pay. A few practical benchmarks:
- 15% — fair, standard service where the meal and timing were fine but nothing stood out.
- 18–20% — attentive service: drink refills, timely check-ins, a friendly attitude, or handling a complication like a special diet.
- 20%+ — exceptional service, large groups, or when the server went out of their way.
- 10% or less — genuinely slow, cold, or wrong order with no recovery. Most diners still leave at least 10% unless the experience was unacceptable.
For bars, a common rule is $1–$2 per drink or 15–20% of the bar tab. For taxis, ride shares, food delivery, and hair salons, 15–20% is also expected. For counter-service coffee shops, bellhops, and valets, a few dollars is more appropriate than a percentage.
A subtle habit worth building: tip on the pre-tax bill, not the post-tax total. Tax goes to the government, not the server, so basing the tip on the smaller pre-tax number is both fair and standard. This calculator uses whatever bill amount you enter, so if you want to tip on pre-tax, type the pre-tax subtotal.
Examples
Example 1 — A typical dinner for one. Your check is $100 before tip and the service was solid. A 15% tip is $15.00, bringing the total bill to $115.00. If you want to round up and show appreciation, 20% gives a $20.00 tip and a $120.00 total — an extra $5 for a better experience.
Example 2 — Splitting a group bill. Four friends run up a $84.50 tab and decide on an 18% tip. The tip works out to $15.21, the total bill is $99.71, and divided by four people each person owes $24.93. Nobody has to cover the odd cents; everyone simply pays their share.
Example 3 — A large celebration. A party of ten racks up a $2,500 banquet and the restaurant has not added automatic gratuity. At 20%, the tip is $500.00, the total bill is $3,000.00, and spread across five couples each one pays $600.00. The calculator scales cleanly to bills in the hundreds of thousands without losing precision.
Example 4 — Zero or minimal bill. If the bill itself is $0 (for instance, a complimentary dessert), the tip is correctly $0.00 and the total stays $0.00 — you never get a nonsensical charge for a free item.
FAQ
How do I calculate a tip?
Multiply the bill amount by the tip percentage, then divide by 100. On a $60 bill at 20%, that is 60 × 20 ÷ 100 = $12.00. Add it back to the bill for a total of $72.00. This calculator does that step instantly and also shows the per-person split.
What is the standard tip percentage in the US?
For sit-down restaurants, 15% is the traditional floor and 18–20% is increasingly the expectation for good service. Many diners now default to 20% because tipped workers receive a lower base wage. Bars, delivery, taxis, and salons follow the same 15–20% guideline.
How do I split the tip among multiple people?
Take the total bill including tip and divide it by the number of people. If a $99.71 total is split four ways, each person pays $24.93. Enter your bill, the tip percentage, and the number of people in the boxes above and the per-person figure is computed for you.
Should I tip on the pre-tax or post-tax amount?
Convention is to tip on the pre-tax subtotal, because sales tax goes to the government rather than the server. The difference is small, but tipping on pre-tax is the fairer and more standard approach. Type the pre-tax subtotal into the Bill Amount box if you want the pre-tax method.
Is 15% still an acceptable tip?
Fifteen percent is acceptable for adequate service, but in many US cities it is now considered on the lower end. If service was merely fine, 15% is defensible; if the server was attentive, most diners tip 18–20%. Adjust the slider to match the experience rather than defaulting to a single number.
What if the bill already includes gratuity?
Many restaurants add an automatic gratuity of 18–20% for parties of six or more. Check the receipt line labeled "gratuity" or "service charge." If it is already there, set the tip percentage to 0% so the calculator does not double-tip; an extra dollar or two for great service is optional.
