Formula
Savings = Original Price × (Discount % / 100)
Sale Price = Original Price − Savings
Total Cost = Sale Price × Quantity
How it works
The discount amount is computed by multiplying the original price by the discount percentage expressed as a decimal. Subtracting that amount from the original price gives the sale price. When purchasing multiple units, total cost and total savings are scaled by the quantity.
Sales tax is not included; add local tax to the total cost for a full out-of-pocket estimate.
Worked example
$200 item at 30% off
- Original price = $200
- Discount = 30% → savings per item = $200 × 0.30 = $60
- Sale price = $200 − $60 = $140
- Buying 1 unit: total cost = $140, total savings = $60
Sale price is $140.00; you save $60.00
Common mistakes to avoid
- Comparing a Black Friday price to the inflated "original" MSRP that retailers sometimes raise in the weeks before the sale to make the discount look larger.
- Ignoring total cost including shipping — a 40% discount can be offset by $30 shipping on a small item.
- Multiplying savings by quantity before confirming availability, leading to disappointment when limited-quantity deals sell out.
Key terms

- The fraction of the original price subtracted to arrive at the sale price, expressed as a percentage.

Frequently asked questions
- How do I verify that a Black Friday deal is genuinely discounted?
- Use a price-history tracker (such as CamelCamelCamel for Amazon) to see whether the listed "original price" reflects what the item actually sold for in recent months.
- Is Black Friday always the best time to buy electronics?
- Not necessarily. New model releases often mean last year's tech goes on sale at deeper discounts. July sales events and end-of-year clearance can sometimes beat Black Friday pricing.
- How do I calculate the price after stacking a store coupon on top of a Black Friday discount?
- Apply discounts sequentially. A 20% Black Friday discount followed by a 10% coupon: Sale Price = Original x 0.80, then Final = Sale Price x 0.90.
