The Restaurant Bill Calculator is the complete solution for computing a full restaurant tab from start to finish. Unlike simpler tip calculators, this tool accounts for all three components of a restaurant bill: the food and drink subtotal, the applicable sales tax, and the desired tip or gratuity. By combining all three, it delivers the complete grand total and an optional per-person split — everything you need to know before reaching for your wallet.
Restaurant bills can be surprisingly confusing. The menu price is just the starting point — sales tax rates vary by state and city (ranging from 0% in states like Montana to over 10% in some cities), and gratuity norms add another 15–25% on top of that. The result is that a meal that looks like $60 on the menu can easily become $75–85 by the time you've accounted for taxes and an appropriate tip.
This calculator makes the total completely transparent. It shows each cost component separately (tax amount and tip amount) so you can verify each piece, then sums them for the final total. Whether you're budgeting for a dinner out, checking a bill at the table, or planning a company meal reimbursement, this tool provides the clarity you need in seconds.
The per-person feature divides the complete grand total (including tax and tip) equally among your party, giving each person one clear number to pay — no confusion, no guesswork.
The restaurant bill calculation works through three additive components:
$$\text{Tax Amount} = \text{Subtotal} \times \frac{\text{Tax Rate}}{100}$$
$$\text{Tip Amount} = \text{Subtotal} \times \frac{\text{Tip Percentage}}{100}$$
$$\text{Grand Total} = \text{Subtotal} + \text{Tax Amount} + \text{Tip Amount}$$
$$\text{Per Person} = \frac{\text{Grand Total}}{\text{Number of People}}$$
Note that the tip in this calculator is calculated on the pre-tax subtotal, which is the traditional etiquette. Some people choose to tip on the post-tax total, which gives a slightly higher tip but is also acceptable.
Example: Subtotal of $80, tax rate 9%, tip 20%, 2 people:
$$\text{Tax} = 80 \times 0.09 = \$7.20$$
$$\text{Tip} = 80 \times 0.20 = \$16.00$$
$$\text{Grand Total} = 80 + 7.20 + 16.00 = \$103.20$$
$$\text{Per Person} = \frac{103.20}{2} = \$51.60$$
The grand total is what you will actually pay for the meal — this is the number to check against your budget or present when settling the bill. The tax amount and tip amount shown separately allow you to verify each component and confirm there isn't a duplicate charge (e.g., if the restaurant has already added a service charge).
The per person amount is the complete cost for each individual, including food, tax, and tip. This is the cleanest number to use when splitting and eliminates any need to separately discuss tip on top of the food split.

Sales tax on restaurant meals varies by state and locality. Some states (Montana, Oregon, New Hampshire, Delaware) have no sales tax at all. Others, like California, have base rates of 7.25% plus local additions. New York City's restaurant tax is 8.875%. Texas is 8.25%. The national average across states with sales tax is approximately 6–8%. Check your state and city's current rate for accuracy — many municipalities have special food service tax rules that differ from general sales tax.
This calculator tips on the pre-tax subtotal, which is the traditional and technically correct etiquette. The logic is that the tax is a government levy, not a reflection of the service provided. However, tipping on the post-tax total (a slightly higher amount) is also common and well-appreciated. The difference on a $60 meal with 8% tax is only about $1.40 in tip at 18%, so either approach is acceptable. The important thing is that service workers receive an adequate gratuity.
If your bill already includes a service charge, auto-gratuity, or mandatory tip (common for large parties or certain restaurants), you should enter 0% tip in this calculator since the gratuity is already factored in. Check your bill carefully for line items labeled 'service charge,' 'gratuity,' or 'staffing fee.' Adding an additional tip on top of a mandatory service charge is optional — some diners add a small extra for exceptional service, while others consider the included charge sufficient.
Yes — you can use the tax field to enter any tax or VAT (Value Added Tax) rate applicable in your country. In the UK, restaurant food is subject to 20% VAT on most items. In Germany, it's 7% for food (19% for alcohol). In Canada, it's the GST/HST rate, which varies by province. Enter the applicable rate for your location, and the calculator will correctly add it to your subtotal. Note that in countries where prices are listed inclusive of VAT, the subtotal you enter should be the pre-tax price — though menus often show tax-inclusive prices abroad.
Absolutely. For delivery orders, the bill often includes multiple charges: food subtotal, delivery fee, and sometimes a service fee from the platform. For tip purposes, it's most accurate to enter just the food subtotal (not the delivery or service fees) as your tip base, since delivery tips go to the driver and service fees go to the platform. Then calculate your delivery tip separately, typically 15–20% of the food subtotal or a minimum of $3–5, whichever is higher.
Most restaurant receipts clearly show the subtotal (or 'food and beverage' amount) as a line item before tax is added. Look for it in the itemized section — it's the sum of all your menu items. The tax line below it shows the calculated tax amount. If your receipt shows only a total with a tax percentage noted, you can back-calculate: Subtotal = Total / (1 + Tax Rate). For example, if the total is $108 with 8% tax: $108 / 1.08 = $100 subtotal.
