What Is the California Sales Tax Calculator?
Applies to: United States — State of California. This tool estimates the sales tax and total price on a taxable purchase in California. California has a statewide base sales tax rate of 7.25% (the highest statewide base rate in the US), but most cities and counties add district taxes on top, pushing the combined rate to roughly 7.25%–10.75% depending on location. Always check the rate for the specific city or ZIP code where the sale occurs.
How to Use It
Enter the purchase price before tax, then enter the applicable combined sales tax rate as a percentage. If you only owe the statewide base rate, use 7.25. The calculator returns the dollar amount of sales tax and the total price you will pay.
The Formula Explained
Sales tax is a simple percentage of the price: \( \text{Tax} = \text{Price} \times (\text{Rate} \div 100) \). The total you pay adds the tax back to the price:
$$\text{Total} = \text{Price} \times \left(1 + \frac{\text{Rate (\%)}}{100}\right)$$Because the rate is divided by 100, a 7.25% rate becomes the multiplier \(0.0725\).
Worked Example
Suppose you buy an item for $100 in a city with the base 7.25% rate.
$$\text{Tax} = 100 \times 0.0725 = \$7.25$$$$\text{Total} = 100 + 7.25 = \$107.25$$If the local combined rate were 9.5%, tax would be $9.50 and the total $109.50.
California Combined Sales Tax Rates by City
California's statewide base sales and use tax rate is 7.25%, the highest base rate in the United States. Many cities and counties add local district taxes on top of this base, producing combined rates that vary by location. The table below lists commonly cited combined rates for major California cities. Local district taxes change frequently, so always verify the current rate for a specific address using the California Department of Tax and Fee Administration (CDTFA) rate lookup before relying on these figures for filing or compliance.
| City | County | Combined Rate |
|---|---|---|
| Statewide base (minimum) | — | 7.25% |
| San Diego | San Diego | 7.75% |
| Fresno | Fresno | 8.35% |
| San Francisco | San Francisco | 8.625% |
| Sacramento | Sacramento | 8.75% |
| Los Angeles | Los Angeles | 9.50% |
| Oakland | Alameda | 10.25% |
For example, a $100 purchase in Los Angeles at the 9.5% combined rate produces a total of $109.50. Rates shown are illustrative of commonly documented values and should be confirmed against current CDTFA data.
Tax and Total Across Different Prices and Rates
The amount of sales tax owed scales directly with both the purchase price and the applicable combined rate. The table below shows the tax amount and final total for four common purchase prices at four representative California rates — the statewide base (7.25%), a mid-range district rate (8.5%), the Los Angeles rate (9.5%), and a high district rate (10.75%). Each total is computed as \(\text{Total} = \text{Price} \times \left(1 + \frac{\text{Rate}}{100}\right)\).
| Price | 7.25% (tax / total) |
8.5% (tax / total) |
9.5% (tax / total) |
10.75% (tax / total) |
|---|---|---|---|---|
| $50 | $3.63 / $53.63 | $4.25 / $54.25 | $4.75 / $54.75 | $5.38 / $55.38 |
| $100 | $7.25 / $107.25 | $8.50 / $108.50 | $9.50 / $109.50 | $10.75 / $110.75 |
| $500 | $36.25 / $536.25 | $42.50 / $542.50 | $47.50 / $547.50 | $53.75 / $553.75 |
| $1000 | $72.50 / $1,072.50 | $85.00 / $1,085.00 | $95.00 / $1,095.00 | $107.50 / $1,107.50 |
Notice that the difference between the lowest (7.25%) and highest (10.75%) rate on a $1,000 purchase is $35.00 in tax — a meaningful gap that explains why the exact location of a sale matters. For a $500 purchase at the 7.25% base rate, the tax is $36.25 for a total of $536.25.
FAQ
Is the rate the same everywhere in California? No. The 7.25% base applies statewide, but local district taxes vary, so the combined rate differs by location.
Are all purchases taxable? No. Most tangible goods are taxable, but many groceries, prescription medicine, and some services are exempt.
How do I find my exact rate? Use the California Department of Tax and Fee Administration (CDTFA) rate lookup by city or ZIP code.
