Average US sales tax: 6-10%. Check your receipt for exact rate.
How to Calculate Total with Tax and Tip
Understanding your full bill including tax and tip helps you budget accurately and avoid surprises. Here's the formula:
Total = Subtotal + (Subtotal × Tax Rate) + (Subtotal × Tip Rate)
Example: Your meal costs $50, the sales tax is 8%, and you want to leave a 20% tip.
- Subtotal: $50.00
- Tax (8%): $50 × 0.08 = $4.00
- Tip (20%): $50 × 0.20 = $10.00
- Total: $50 + $4 + $10 = $64.00
Use our calculator above to do this math instantly. Just enter your bill amount, tax rate, tip percentage, and number of people if you're splitting the bill.

Should You Tip on Tax?
This is a common question with different opinions. Here are the two approaches:
Traditional Etiquette: Tip on Subtotal Only
Purists argue that you should only tip on the pre-tax subtotal because:
- Tax is a government charge, not a service provided by the restaurant
- Traditional tipping etiquette is based on the cost of food and service
- Tipping on tax is a relatively recent practice
Modern Practice: Tip on Total Including Tax
Many people now tip on the post-tax total because:
- It's simpler to calculate
- The difference is usually small
- Some argue servers still provide service on the full amount
Example of the difference: For a $50 meal with 8% tax ($54 total) and 20% tip:
- Tipping on subtotal: $50 × 0.20 = $10.00
- Tipping on total: $54 × 0.20 = $10.80
- Difference: $0.80
Ultimately, either approach is acceptable. The most important thing is to leave a fair tip for good service.
Understanding State Tax Rates
Sales tax in the United States is complicated because it's set at multiple levels:
State Sales Tax
Each state sets its own base sales tax rate. This ranges from 0% (in states with no sales tax) to 7.25% in California.
Local Sales Tax
Cities, counties, and special districts can add their own sales tax on top of the state rate. This is why the combined rate varies even within the same state.
Why Rates Vary
States use sales tax to fund public services like education, infrastructure, and emergency services. States with no income tax (like Florida, Texas, and Washington) often rely more heavily on sales tax.
How to Find Your Local Rate
Check your receipt - the tax amount and rate are usually listed. You can also search online for "[your city] sales tax rate" or use our calculator with your local rate.
Frequently Asked Questions
Should I tip on the pre-tax or post-tax amount?
The traditional etiquette is to tip on the pre-tax subtotal. However, many people now tip on the post-tax total for simplicity. The difference is usually small - for a $50 meal with 8% tax, tipping 20% on the subtotal is $10, while tipping on the total ($54) is $10.80. Either approach is acceptable, but tipping on the subtotal is considered more proper.
How do I calculate tax and tip together?
To calculate both, first find the tax amount (subtotal × tax rate), then find the tip amount (subtotal × tip percentage). Add both to the subtotal. Example: $100 meal, 8% tax = $8 tax, 20% tip = $20 tip. Total = $100 + $8 + $20 = $128.
What states have no sales tax?
Five states have no general sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. However, Alaska allows local jurisdictions to impose their own sales taxes, so some areas in Alaska do have sales tax. In the other four states, there's truly no sales tax at any level.
Which states have the highest sales tax?
The states with the highest combined state and local sales tax rates are: Louisiana (9.55%), Tennessee (9.53%), Arkansas (9.48%), Washington (9.29%), and Alabama (9.22%). These rates include both state and average local taxes.
Do I need to include tax when splitting a bill?
Yes, when splitting a bill, you should include tax in the total. The tax is part of the actual cost of the meal. Calculate the total including tax and tip, then divide by the number of people. For example, if the subtotal is $80, tax is $6.40 (8%), and tip is $16 (20%), the total is $102.40.
How do I calculate a 20% tip with tax?
Calculate the tip on the pre-tax subtotal: Subtotal × 0.20 = tip amount. Then add the subtotal, tax, and tip together. Example: $50 meal with 8% tax. Tip = $50 × 0.20 = $10. Total = $50 (subtotal) + $4 (tax) + $10 (tip) = $64.
Is tax included in menu prices?
In the United States, menu prices typically do not include sales tax. Tax is added at the time of purchase. This is different from some other countries where prices include tax. Always check your receipt to see the tax amount separately listed.
Why do some places have higher tax rates than others?
Sales tax rates vary because they're set by state and local governments to fund public services like schools, roads, and emergency services. States with no income tax (like Florida and Texas) often rely more heavily on sales tax. Local cities and counties can add their own taxes on top of state rates.
