Quick Discount Calculations
How to Calculate Discounts
Three ways to calculate discounts:
Price & Discount %
Formula: Final Price = Original × (1 - Discount%/100)
Example: $100 with 25% off
$100 × (1 - 25/100) = $100 × 0.75 = $75
Find Discount %
Formula: Discount% = [(Original - Final) / Original] × 100
Example: From $100 to $75
[(100-75)/100] × 100 = 25%
Find Original Price
Formula: Original = Final / (1 - Discount%/100)
Example: $80 after 20% off
$80 / (1 - 20/100) = $80 / 0.80 = $100
Common Discount Scenarios
Black Friday Sale
Scenario: TV marked $800 with 40% off

You Pay: $480 | You Save: $320
Clearance Sale
Scenario: Dress originally $150, now $90
Calculation: [(150-90)/150] × 100 = 40%

Student Discount
Scenario: Laptop $720 after 10% student discount
Calculation: $720 / (1 - 0.10) = $800
Original: $800 | Saved: $80

Frequently Asked Questions
How do I calculate discount percentage?
Formula: [(Original Price - Sale Price) / Original Price] × 100. Example: Item was $100, now $75. Discount = [(100-75)/100] × 100 = 25%. Use our "Find Discount %" tab for instant results.
How to calculate 20% off?
Multiply the price by 0.80 (or subtract 20% from the price). Example: $50 with 20% off = $50 × 0.80 = $40. You save $10. Use our calculator to get instant results for any discount.
What's the difference between discount and discount percentage?
Discount is the actual amount saved (dollars/rupees), while discount percentage is the proportion of the original price. Example: 25% off $100 means 25% discount and $25 discount amount.
How to stack multiple discounts?
Apply discounts sequentially, not additively. Example: 20% off then 10% off $100 = $100 × 0.80 × 0.90 = $72 (not 30% off). The order matters - calculate each discount on the new price.
How to find original price from sale price?
Divide sale price by (1 - discount percentage as decimal). Example: $80 after 20% off = $80 / (1 - 0.20) = $80 / 0.80 = $100 original. Use our "Find Original" tab.
Is 50% off the same as buy one get one free?
Yes! BOGO (buy one get one) is effectively 50% off the total when items are the same price. Two $20 items = $40 total, pay $20 = 50% discount on the total purchase.
How do stores calculate discount prices?
Retailers multiply original price by (1 - discount percentage). Example: $200 item with 30% off = $200 × 0.70 = $140. They may round to nearest dollar for clean pricing ($139.99).
What's a good discount percentage?
Depends on the item and timing. Typical sales: 10-25% (regular sales), 30-50% (seasonal clearance), 50-70% (final clearance). Electronics often have smaller margins (10-20%) while clothing goes higher (30-70%).
