A tip calculator takes the guesswork out of calculating a tip. Enter your bill, pick a percentage, and this tool shows the tip amount, the total, and the per-person cost when you split. You can add sales tax before the tip and choose your currency. The calculation runs in your browser, so nothing leaves your device.
How to Use the Tip Calculator
Four inputs cover most situations. The bill amount and tip percentage are all you need for a quick result. Tax and split are optional toggles for when the situation calls for them.
- Enter the bill amount. This is the pre-tax total on your check.
- Pick a tip percentage. Tap one of the preset buttons (15%, 18%, 20%, 25%) or type a custom number.
- Toggle on Add Sales Tax if you want the tip calculated on the tax-included total. Enter the combined state and local tax rate.
- Toggle on Split the Bill and enter the number of people to see the per-person amount.
The result panel updates with the tip amount, total, and (when splitting) what each person pays. Use the currency selector to switch between dollars, euros, pounds, and other currencies. The print and copy buttons let you take the numbers with you.
Tip Calculator Formula
The math behind any tip calculation is straightforward. The calculator applies these steps:
| Step | Formula | Example ($100 bill, 20% tip, 8% tax) |
|---|---|---|
| Calculate tax | Tax = Bill x Tax Rate / 100 | $100 x 8 / 100 = $8.00 |
| Add tax to bill | Pre-Tip Total = Bill + Tax | $100 + $8 = $108.00 |
| Calculate tip | Tip = Pre-Tip Total x Tip Percent / 100 | $108 x 20 / 100 = $21.60 |
| Find total | Total = Pre-Tip Total + Tip | $108 + $21.60 = $129.60 |
| Split (optional) | Per Person = Total / Number of People | $129.60 / 4 = $32.40 |
When the tax toggle is off, the tip is calculated directly on the bill amount: Tip = Bill x Tip Percent / 100. When tax is on, the tip applies to the combined bill-and-tax total. This matters because a $100 bill at 20% tip gives a $20 tip without tax, but with 8% tax the tip becomes $21.60. The difference adds up over several meals.
How Much Should You Tip?
Tipping customs vary by country and service. These ranges reflect common practice in the United States. The right amount depends on the service quality, the type of establishment, and local norms.
Restaurants and Dining
Full-service restaurants expect 15% to 20% of the pre-tax bill. For outstanding service, 25% or more is appropriate. Buffet restaurants typically warrant 10% since the server handles drinks and table clearing rather than taking and delivering orders. A $65 dinner bill at 18% gives a $11.70 tip, bringing the total to $76.70 before tax.
Delivery and Takeout
Food delivery drivers deserve $3 to $5 or 15% to 20%, whichever is higher, especially for large orders or bad weather. Grocery delivery tips range from $5 to $10 depending on order size and distance. For pizza delivery, $2 to $5 is common, with more for large or heavy orders. Takeout orders do not require a tip, though 10% is appreciated when the order is complex.
Hair, Nail, and Spa Services
Hairdressers and barbers expect 15% to 20%. A $45 haircut at 20% gives a $9 tip. Nail technicians typically receive $3 to $5 per service or 15% to 20% of the bill. Massage therapists, estheticians, and spa providers expect 15% to 20% of the service price. Tattoo artists often receive 15% to 20%, and the tip is cash when possible.
Other Services
Cab and rideshare drivers expect 15% to 20%. Hotel housekeeping deserves $2 to $5 per night, left daily rather than at the end of your stay. Bartenders expect $1 to $2 per drink or 15% to 20% of the tab. Car wash attendants and furniture delivery crews appreciate $5 to $10.
Should You Tip on Tax?
This depends on where you eat. In many US states, the customary practice is to calculate the tip on the pre-tax subtotal. The tax is a government charge, not part of the service. However, some people tip on the post-tax total out of habit or generosity. The difference is small on a single bill but compounds across many meals.
On a $80 bill with 8.5% tax ($6.80), tipping 20% on the pre-tax amount gives $16.00. Tipping 20% on the tax-included total gives $17.36. That is $1.36 more per meal. Over 50 meals a year, the gap reaches $68. Use the calculator's tax toggle to compare both scenarios and decide which approach fits your budget.
Splitting the Bill
Splitting equally is the simplest approach when everyone orders similar items. Toggle on Split the Bill and enter the number of people. The calculator divides the total (including tip and optional tax) evenly. For $240 split four ways at 20% tip, each person pays $72.
Unequal splits are harder. One method: each person calculates their own portion of the bill separately, applies the same tip percentage, and adds their share of tax. The calculator handles this if each person runs their own calculation. For groups with one person covering the tip, enter the full bill, apply a higher tip percentage to account for the extra contribution, and split the remaining total.
Use the Reverse Tip Calculator when you know the total you paid but not the original bill, the Tip Percentage Calculator when you know the bill and the tip but want the exact rate, and the Tip-Out Calculator when you have to split a shift's tips among support staff. Pair this calculator with the Number to Words Converter when writing a check for the bill amount.
