How do I calculate discount?

Sale Price = Original × (1 - Discount%/100). For 30% off $100: $100 × 0.70 = $70.

How do I calculate the discount percentage?

Discount % = (Savings / Original Price) × 100. For example, if you save $20 on a $100 item: (20/100) × 100 = 20% discount.

What is the difference between discount and sale price?

Discount is the amount saved (Original - Sale Price). Sale price is the final price after discount. For example, $100 item with 20% discount: $20 savings, $80 sale price.

Can I stack multiple discounts?

Typically, discounts are applied sequentially. First discount is applied to original price, then second discount to the already discounted price. Some stores may have restrictions.

How do I calculate the original price from sale price?

Original Price = Sale Price ÷ (1 - Discount%/100). For example, if sale price is $70 with 30% discount: $70 ÷ 0.70 = $100 original price.

Are discounts calculated before or after tax?

Discounts are usually calculated on the pre-tax price. Tax is then applied to the discounted price. However, this can vary by location and store policy.

Step-by-Step Scenario

Example Scenario

Original Price

$100

Discount

25%

(percentage)

1

Convert Discount Percentage to Decimal

Discount (D) = 25% ÷ 100 = 0.25

Always convert percentage to decimal form for calculation

2

Calculate Savings

S = O × (D ÷ 100)
S = $100 × 0.25 = $25

S = $25

3

Calculate Final Price

F = O - S
F = $100 - $25 = $75

F = $75

Important Notes

Discounts are calculated as percentages of the original price. The formula is: Savings = Original × (Discount%/100).
Final price is calculated by subtracting savings from the original price: Final Price = Original - Savings.
Discount percentages must be between 0 and 100. A 0% discount means no savings, and a 100% discount means the item is free.
Some stores may have restrictions on discount stacking. Always check store policies before applying multiple discounts.
Tax is typically calculated on the discounted price, not the original price. Check local tax regulations.
