> The California sales tax calculator works out the sales tax on a purchase in California – the 7.25% state rate plus your local rate – and the total price, or removes the tax from a price that already includes it.

## Inputs

- Purchase amount
- Local sales tax rate (district taxes, 0–4%) (%)
- The amount

## Results

- Combined sales tax rate
- Price before tax
- Sales tax amount
- Total price

## Formula

```
Combined rate = state rate 7.25% + local rate
Sales tax = price × combined rate
Price before tax = total ÷ (1 + combined rate)
```

## Explanation

California has the highest statewide base sales tax rate in the U.S. – 7.25% – and local district taxes bring the total to between 7.25% and over 10.5% depending on where you buy, for example about 9.5–9.75% in Los Angeles. Local rates change often – check your exact rate with the state revenue department for large purchases.

### How to use the California Sales Tax Calculator

- **Purchase amount**
- **Local sales tax rate (district taxes, 0–4%)**
- **The amount**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter the purchase amount and your local (county and city) sales tax rate, and choose whether the amount includes tax.

### Tips

- Tax figures here are estimates for planning – your actual tax depends on credits, deductions and local rules.
- Check the tax year and filing status before you rely on a result.
- Use gross (before-tax) figures unless a field asks for take-home pay.
- When in doubt, confirm with the tax authority's own calculator or a tax professional.

### Common mistakes to avoid

- Confusing marginal and effective tax rates.
- Adding sales tax to a price that already includes it.
- Forgetting payroll taxes (Social Security and Medicare) on wages.

- **Total price** = [Price before tax] + [Sales tax amount]
