1How Discounts & Sales Taxes are Calculated

A discount calculator helps you find the net price of an item after applying a percentage discount, plus adding any sales tax that may apply to the discounted subtotal.

Formula & Math Explanation

Final Price = (Original Price - Discount Amount) × (1 + Tax Rate / 100)
  • •Discount Amount = Original Price × (Discount Percent / 100).
  • •Subtotal = Original Price - Discount Amount.
  • •Sales Tax Portion = Subtotal × (Tax Rate / 100).

2Discount & Tax Calculation Example

You find a jacket priced at ₹5,000 on sale with a 20% discount. The local sales tax is 5%.

  1. Calculate Discount Savings: ₹5,000 × 20 / 100 = ₹1,000.
  2. Calculate Subtotal: ₹5,000 - ₹1,000 = ₹4,000.
  3. Calculate Sales Tax on Subtotal: ₹4,000 × 5 / 100 = ₹200.
  4. Calculate Final Price: ₹4,000 + ₹200 = ₹4,200.
Result Summary: The jacket will cost you ₹4,200. You save a total of ₹1,000 on the original purchase price.

Discount & Sales FAQs

Multiply the original price by the discount percentage, then divide by 100 to get the discount amount. Subtract that from the original price.
