Sales Tax Calculator

Add or remove sales tax using a state rate and a local percent you type. No ZIP lookup.

Smart Tips

• Type the state base rate and the local percent separately. The page adds them. It does not look up a ZIP code.

• Removing tax divides the total by 1 plus the combined rate. A 7.5% combined rate on $107.50 returns a $100 price.

• A zero in both rate fields leaves the price unchanged.

• California publishes a statewide rate plus district taxes. Those figures are an illustration in the source note, not a rate this page fills in.

The Formula

Tax = Price × (state rate + local rate) ÷ 100

State Base percent you type
Not looked up

Local Second percent you type
City, county, or district

Total Price + tax
When you are adding tax

Price Total ÷ (1 + combined rate)
When you are removing tax

The tax on this page is the price multiplied by the sum of the two percents you enter. No rate table is stored. California's Department of Tax and Fee Administration describes a statewide rate plus separate district taxes; that split is why this page has two fields, and the numbers still have to be typed.

Key Insights

Two typed rates

State and local stay separate so a district add-on is visible.

No address

A ZIP code, city name, or street is not an input.

Add or remove

The same combined rate works in both directions.

Exemptions are not guessed

Groceries, clothing, and business purchases are taxed only if you include them in the price you type.

Frequently Asked Questions

No. You type the state percent and the local percent. There is no address field and no rate table on the page.

Add the state percent and the local percent, then multiply the price by that combined rate. A $100 price with 6% state and 1.5% local has $7.50 of tax and a $107.50 total.

Divide the total by 1 plus the combined rate. The tax is the total minus that price. Using 6% and 1.5% on $107.50 returns $100.

The tax is zero and the total equals the price. A negative price is rejected.

A jurisdiction can round each line, exempt part of the sale, or stack more than one district. This page applies one state percent and one local percent to the whole amount you type. This is an estimate, not tax advice.

California's Department of Tax and Fee Administration says the statewide rate is 7.25% and that local district taxes often add 0.10% to 2.00%. This calculator does not look up that table, a ZIP code, or any other state's rate. You type both percents. Tax = price × (state + local) ÷ 100. No ZIP-based rates are invented or bundled.
