Discount Calculator

Calculate final price and savings after discount.

Σ The Formula

Final Price = Original Price × (1 - Discount% / 100) | Savings = Original Price × (Discount% / 100)

Real World Examples

Black Friday Sale
$200 item with 30% off: Final = $200 × 0.70 = $140, Save $60
Clearance
$50 item with 75% off: Final = $50 × 0.25 = $12.50, Save $37.50
Member Discount
$150 item with 15% off: Final = $150 × 0.85 = $127.50, Save $22.50
BOGO 50% Off
$80 item with 50% off: Final = $80 × 0.50 = $40, Save $40

# About This Calculator

Discount calculations are essential for smart shopping, helping you understand true savings and compare deals across different stores and sales events. Whether it's Black Friday, clearance sales, or member discounts, knowing the final price helps you make informed purchasing decisions.

Retailers use various discount strategies: percentage off (30% off), dollar amount off ($20 off), buy-one-get-one (BOGO), tiered discounts (buy 2 get 20% off), and stacking discounts (coupon + sale). Understanding how these work prevents overspending and helps you spot genuinely good deals.

The calculation is straightforward: multiply the original price by (1 - discount percentage as a decimal). For example, 25% off means you pay 75% of the original price. The savings amount is simply the original price minus the final price, showing exactly how much money you're saving.

This calculator instantly shows both the final price you'll pay and the total savings, making it perfect for comparison shopping, budgeting, or verifying sale prices at checkout. It's especially useful during major sales events when quick mental math isn't practical.

How To Use

  1. Enter original price.
  2. Enter discount percentage.

Frequently Asked Questions

How do I calculate multiple stacked discounts?+

Apply discounts sequentially, not additively. For example, 20% off then 10% off: First discount: $100 × 0.80 = $80. Second discount: $80 × 0.90 = $72. Final price is $72, NOT $70 (which would be 30% off). Stacked discounts are less than the sum!

What does 'up to 70% off' really mean?+

This is marketing language meaning SOME items are 70% off, but most are less. Typically only a few clearance items get maximum discounts. Read the fine print and check individual item discounts rather than assuming everything is 70% off.

Is a bigger discount percentage always a better deal?+

Not necessarily! Compare final prices, not percentages. A $50 item at 50% off ($25 final) might be more expensive than a $40 item at 30% off ($28 final) from a competitor. Also consider quality, shipping, and return policies.

How do I reverse-calculate the original price from a sale price?+

Divide the sale price by (1 - discount as decimal). For example, if something costs $60 after 25% off: $60 / 0.75 = $80 original price. Useful for verifying advertised 'original' prices aren't inflated.

What's the difference between % off and % of original price?+

They're complements: 30% off means you pay 70% of original. 25% off means you pay 75% of original. To find final price: multiply by (100% - discount%). To find discount: multiply by discount%.
