Free Tip Calculator

What is a tip calculator?
A tip calculator is a free online tool that computes the gratuity amount for a restaurant bill and splits the total between multiple people. Enter the bill amount, choose a tip percentage (or enter a custom one), and specify how many people are sharing — the calculator shows the tip amount, total bill, and cost per person instantly.
You hand the waiter your card and then the awkward question comes up: "How much should we tip?" and suddenly everyone's doing mental math. This calculator kills the guesswork — punch in the bill, pick a percentage, and it tells you exactly what everyone owes. Works for dinner, delivery, bar tabs, pretty much any tipping situation.
Most tip calculators just split the total evenly and call it a day. This one lets you tip on the pre-tax amount (which is what etiquette actually recommends), set a custom tax rate if you want to get precise, round up for cash payments, and save your favorite percentages so you don't have to re-enter them next time. It's the little things.
How the tip calculator works
It's just multiplication and division: bill times tip percentage gives you the tip amount, add that to the bill for the total, and if there are multiple people, split both the tip and the total. All the math happens right in your browser, so nothing gets sent to a server and nothing is stored anywhere.
For example: a $85 dinner bill with an 18% tip produces an $15.30 tip and a $100.30 grand total. Split four ways, that's $25.08 per person — including $3.83 tip each.
The calculator also offers a pre-tax mode, which is useful when you want to tip based on the food and drink subtotal before sales tax. Toggle between post-tax (total bill) and pre-tax (subtotal) to see how the difference affects the gratuity. A "round up" option lets you round the tip or total to the nearest dollar for easier payment when splitting in cash. If you frequently tip the same percentages, star your favorites and they stay saved for next time.
When to use a tip calculator
Group dinners are where this thing really earns its keep. Six people, three bottles of wine, someone ordered the $60 steak, and now it's math o'clock. Instead of doing the "who had what" dance, everyone can throw in their portion and the calculator handles the split. Less awkwardness, more getting on with your night.
The free tip calculator on CalcInstant also works for any service industry tipping scenario: hair salons, spas, taxi and rideshare drivers, hotel housekeeping, tour guides, and movers. Just enter the service total and your preferred percentage. For bar service and bartenders, $1–2 per drink or 15–20% of the tab is standard. At wedding receptions or catered events where gratuity is included in the contract, use the calculator to verify the 18–20% service charge is correct before paying extra.
Travelers visiting the US from countries without a tipping culture often find the calculator especially useful — it removes the guesswork and helps budget accurately for gratuities across an entire trip. Similarly, international travelers from the US can use it to calculate appropriate tips abroad while accounting for local customs and exchange rates.
Tip percentage guide
US tipping norms vary by service type. For sit-down restaurants, 15-20% is standard; 20-25% for exceptional service. Food delivery typically warrants 15-20% of the order total. Taxi and rideshare: 15-20%. Hair stylists and barbers: 15-25%. Hotel housekeeping: $2-5 per night. Valet parking: $2-5 when retrieving your car. Tour guides: $10-20 per person per day for full-day tours, half that for half-day. Movers: $20-50 per mover depending on the complexity of the move.
When in doubt, 20% is a safe default at most US restaurants. It's easy to calculate mentally (find 10%, double it) and it's become the new standard tip in most cities. Large groups should check whether the restaurant automatically includes a "gratuity" line item (typically 18% for parties of 6 or more) — if so, the calculator can verify that the listed amount is indeed 18% of the pre-tax subtotal. Some restaurants add gratuity but still leave a tip line, so knowing what you have already paid helps avoid double-tipping.
How to use this calculator
- Enter your bill amount — Type the total bill amount before tax in the Bill Amount field. Use a decimal point for cents, e.g. 47.50.
- Choose a tip percentage — Click 15%, 18%, or 20% for a quick selection, or type any custom percentage in the Custom Tip % field.
- Set the number of people — Enter how many people are splitting the bill. The calculator instantly shows the per-person tip and total.
This tip calculator handles every edge case I look for: pre-tax tipping, custom tax rates, rounding for cash payments, and fair per-person splits. The pre-tax mode is a feature most competitors skip entirely. The donut chart makes the bill-vs-tip split instantly clear, and the URL sharing means you can text the exact calculation to your dinner companions.
Frequently asked questions
How do I calculate a 20% tip on a restaurant bill?
Move the decimal point one place left to get 10% of your bill, then double that number to get 20%. For a $45 bill: 10% = $4.50, doubled = $9.00 tip. Add $9.00 to $45.00 for a $54.00 grand total. The calculator does this instantly for any percentage.
Should I tip on the pre-tax or post-tax amount?
Tip on the pre-tax subtotal — that's what etiquette guides recommend. However, most people tip on the post-tax total for convenience since the difference is small. On a $50 pre-tax bill with 8% tax, tipping 20% on pre-tax saves you about $0.80 compared to tipping on the full $54 total.
How do I split a bill and tip between 4 people?
Add the tip to the total bill first, then divide by the number of people. For a $120 bill with 20% tip: $120 × 1.20 = $144 total ÷ 4 people = $36 each. Enter the bill, tip percentage, and party size into the calculator and it shows the per-person amount automatically.
What is a standard tip percentage at restaurants in the US?
15% is the historical minimum, 18% is now considered average, and 20% has become the new standard at sit-down restaurants. For exceptional service, 25% is appropriate. Fast casual and counter service typically expect 10–15%. Food delivery drivers: 15–20% of the order total, minimum $3–5.
How much should I tip a delivery driver?
Tip delivery drivers 15–20% of the order total, with a minimum of $3–5 for small orders. For orders under $20, tip at least $4 regardless of percentage. Bad weather, difficult delivery locations, or large orders justify tipping on the higher end. Always tip in cash when possible — apps sometimes keep a portion.
How do I calculate tip when splitting a bill unevenly?
Calculate the tip percentage on the full bill first, then apply that same percentage to each person's individual portion. If the tip rate is 20% and you owe $32 of a larger bill, your tip share is $6.40. This is fairer than splitting the total tip evenly when people ordered different amounts.
