Sales tax and tip calculator

Tip Calculator with Tax

Calculate tip with sales tax, compare pre-tax and post-tax tipping, and split the final bill before you pay. Use a state tax estimate as a starting point or enter the tax rate printed on your receipt.

State tax estimates are only quick starting points. County, city or town, transit authority, and special-purpose tax district rules may change the actual rate. Restaurant location and the type of food or service purchased can matter as well.

Receipt guidance

What tax rate should you enter?

Use the sales tax rate shown on your receipt when you have it. A state average is helpful for planning, but the final restaurant tax can change by county, city or town, local tax district, restaurant location, and the type of food or service purchased.

Quick answer

How do you calculate tip with tax?

Calculate the sales tax from the subtotal, choose whether the tip is based on the subtotal or the after-tax total, then add subtotal, tax, and tip together. Divide that total by the number of people if you are splitting the check.

Direct answer

Should you tip before or after tax?

Most people calculate a restaurant tip before tax because sales tax is not part of the service price. Tipping after tax is easier and slightly more generous. This calculator lets you compare both methods before you pay.

Formula

How tax and tip are calculated

  • Tax = bill subtotal × tax rate
  • Pre-tax tip = bill subtotal × tip percentage
  • Post-tax tip = (bill subtotal + tax) × tip percentage
  • Total = bill subtotal + tax + tip

Tip calculator with tax FAQs

Should I calculate the tip before tax or after tax?

Most people calculate a restaurant tip before tax because sales tax is not part of the service price. Tipping after tax is simpler and gives a slightly larger tip.

How do I calculate tip with sales tax?

First calculate tax from the bill subtotal. Then calculate the tip from either the pre-tax subtotal or the after-tax total, depending on the tip basis you choose.

Is the state tax estimate exact?

No. A state estimate is only a starting point. In the United States, local rates can vary by county, city or town, transit authority, or special-purpose tax district. Restaurant location and the type of food or service purchased can also matter. Use the rate shown on your receipt for the closest estimate.

What is a 20% tip on a $50 bill before tax?

A 20% pre-tax tip on a $50 bill is $10. If the bill has 8% sales tax, the estimated total is $64 before any rounding.

Can I enter my own tax rate?

Yes. Enter the sales tax rate from your receipt for a closer calculation. The state estimate field is only a convenience option.
