What is a Sales Tax Calculator?

A Sales Tax Calculator is a free online website that assists businesses, freelancers, and purchasers when accurately determining sales tax in seconds. You enter a price and a tax rate (local, state, federal, or custom), and the sales tax calculator gives you instantly:

• The amount of sales tax due,
• The total cost including tax
• The net price without tax (useful if you're working backwards from 'gross' amount)

Whether you are a small business owner doing the billing, an online seller determining eCommerce taxes, or even a consumer checking your receipts, the sales tax calculator is great for quickly giving you accurate results. It is also very handy for creating invoices, confirming totals from a checkout, or just figuring out if you are abiding by regional tax regulations.

How Does the Sales Tax Calculator Work?

Using the tool is simple:

1. Enter the price (either before tax or total including tax).
2. Enter the sales tax rate (%) — for example, 5%, 12%, or 18%.
3. Select calculation mode — add tax to net price or remove tax from gross price.
4. Hit Calculate to get:
   • Sales tax amount
   • Net price (exclusive of tax)
   • Total price (inclusive of tax)

Formula:

• Forward calculation: Sales Tax = Price × (Tax Rate ÷ 100)
• Reverse calculation: Net Price = Gross ÷ (1 + Tax Rate ÷ 100)

Example – Sales Tax Calculation

Suppose a product costs ₹1,000 and the tax rate is 8%.

• Sales Tax = 1,000 × 0.08 = ₹80
• Total Price = ₹1,000 + ₹80 = ₹1,080

Now, if you only know the gross price (₹1,080):

• Net Price = 1,080 ÷ 1.08 ≈ ₹1,000
• Tax Component = 1,080 – 1,000 = ₹80

This shows how the calculator works for both adding and removing tax.
