Discount Formula

Saving = Original price × (Discount % ÷ 100)
Sale price = Original price − Saving

Example: $80 with 25% off → saving = 80 × 0.25 = $20, sale price = $60.

What is a Discount Calculator?

A discount calculator helps you determine the final price of an item after applying a percentage discount. It can also factor in sales tax to give you the true final cost.

How Does It Work?

The calculator uses these formulas:
1. Discount Amount = Original Price × (Discount Percentage ÷ 100)
2. Price After Discount = Original Price - Discount Amount
3. Tax Amount = Price After Discount × (Tax Rate ÷ 100)
4. Final Price = Price After Discount + Tax Amount

Tips for Using the Calculator

  • Always verify the original price is correct
  • Check if tax should be included in your calculation
  • Consider whether the discount applies before or after tax
  • Look for additional discounts that might stack

Frequently Asked Questions

The discount amount is calculated by multiplying the original price by the discount percentage divided by 100. For example, a 20% discount on $100 equals $20 savings (100 × 20 ÷ 100 = 20). The price after discount is then the original price minus the discount amount.

The tax is calculated on the discounted price (not the original price). First, the discount is applied to get the reduced price, then the tax rate is applied to that reduced amount. The final price equals the discounted price plus the tax amount.

This calculator is designed for single-discount calculations. For stacked discounts (like 20% off plus an additional 10%), apply them sequentially rather than adding the percentages. Calculate the first discount, then use that result as the original price for the second discount.

What Is a Discount Calculator?

A discount calculator works out the sale price and how much you save when a percentage is taken off the original price. Multiply the price by the discount rate to get the saving, then subtract it.
