How to Calculate a Discount
Calculating a discount is straightforward once you know the formula. Here's a step-by-step guide to help you figure out the final price after a discount.
- Start with the original price of the item.
- Determine the discount percentage (e.g., 20%).
- Multiply the original price by the discount percentage divided by 100 to get the discount amount.
- Subtract the discount amount from the original price to get the final price.
Discount Formula
Discount Amount = Original Price × (Discount Percentage ÷ 100)
Final Price = Original Price − Discount Amount
Example
If an item costs $80 and has a 25% discount: Discount Amount = $80 × (25 ÷ 100) = $20. Final Price = $80 − $20 = $60. You save $20 on this purchase.

How do I calculate a discount percentage?
To calculate a discount percentage, divide the discount amount by the original price and multiply by 100. For example, if an item is $50 and the discount is $10, the discount percentage is (10 ÷ 50) × 100 = 20%.
What is the formula for calculating a discounted price?
The formula is: Final Price = Original Price − (Original Price × Discount Percentage ÷ 100). For example, a $100 item with a 30% discount costs $100 − $30 = $70.
How do I find the original price before a discount?
To find the original price, divide the sale price by (1 − discount percentage ÷ 100). For example, if you paid $60 after a 25% discount, the original price was $60 ÷ 0.75 = $80. You can also use our reverse discount calculator for this.
Can I calculate a discount with tax?
Yes. First calculate the discounted price, then apply the tax rate to the discounted amount. For example, a $100 item with 20% off is $80, and with 8% tax it becomes $80 × 1.08 = $86.40. Try our discount plus tax calculator for combined calculations.
How do I compare two different discounts?
To compare discounts, calculate the final price for each option. For example, 20% off $100 gives $80, while $15 off gives $85 — so 20% off is the better deal. Our AI comparison feature does this automatically.
What is the difference between percentage discount and fixed amount discount?
A percentage discount reduces the price by a proportion (e.g., 20% off), while a fixed amount discount subtracts a specific dollar value (e.g., $15 off). The better deal depends on the original price.
How do I calculate multiple discounts applied in sequence?
Apply each discount one at a time to the running total. For example, 20% off then 10% off on a $100 item: first $100 × 0.80 = $80, then $80 × 0.90 = $72. Note that this is not the same as a single 30% discount. Use our multiple discount calculator to handle this automatically.
How do bulk or volume discounts work?
Bulk discounts offer a lower per-unit price when you buy larger quantities. For example, 1–9 units at $10 each, 10–49 units at $8 each, and 50+ units at $6 each. The more you buy, the more you save per item.
