Question 1

How do I calculate sales tax?

Accepted Answer

Select 'Add Tax' mode, enter the price before tax and the tax rate percentage. The calculator shows the net price, tax amount, and total price with tax. Formula: Total = Price × (1 + Tax Rate / 100).

Question 2

How do I remove tax from a total price?

Accepted Answer

Select 'Remove Tax' mode, enter the total price (with tax) and the tax rate. The calculator shows the original price before tax. Formula: Price = Total / (1 + Tax Rate / 100). Useful when you see a price with tax and want to know the base price.

Question 3

What sales tax rate should I use?

Accepted Answer

Sales tax rates vary by location (state, county, city). Common rates range from 0% (no sales tax states) to 10%+. Check your local tax rate. Some areas have different rates for different products. Use the rate applicable to your purchase.

Question 4

Can I calculate tax for multiple items?

Accepted Answer

This calculator handles one price at a time. For multiple items, calculate tax for each item separately, or add all item prices together and calculate tax on the total. The tax rate should be the same for all items.

Question 5

How does sales tax differ from VAT?

Accepted Answer

Sales tax (US) and VAT (Value Added Tax, used in many countries) work similarly but are applied differently. Sales tax is added at the point of sale, while VAT is included in the price. Our calculator works for both - use 'Add Tax' for sales tax or 'Remove Tax' to find the price without VAT.
