Sales Tax vs. VAT/GST
The **Sales Tax Calculator** helps consumers and businesses navigate transaction taxes. Unlike the VAT/GST system (which is collected at every stage of production), sales tax is typically only collected once, at the final **point of sale** to the consumer. This makes the calculation crucial for accurately pricing retail goods.
The Two Core Tax Calculations
The core calculations follow the same principles as your VAT/GST calculator:
- **Add Tax (Finding Gross Price):** If the price entered is the **Net Price** (before tax): $$\text{Tax Amount} = \text{Net Price} \cdot \frac{\text{Rate}}{100}$$ $$\text{Gross Price} = \text{Net Price} + \text{Tax Amount}$$
- **Remove Tax (Finding Net Price):** If the price entered is the **Gross Price** (tax included): $$\text{Net Price} = \frac{\text{Gross Price}}{1 + \text{Rate} / 100}$$ $$\text{Tax Amount} = \text{Gross Price} – \text{Net Price}$$
Frequently Asked Questions (FAQ)
Why does sales tax vary by location in the US?
In the United States, sales tax is levied by state, county, and city governments. This means a single purchase can be subject to multiple local taxes, leading to thousands of different tax rates across the country. Our calculator allows you to input the exact combined rate for your location.
