How to Calculate Discounts
Shopping during sales is a great way to save money, but understanding exactly how much you're saving can sometimes be tricky. Our discount calculator helps you instantly find the final price and total savings.
Discount Formula
To calculate the sale price manually, follow these steps:
- Convert the percentage to a decimal (Divide by 100)
- Multiply the original price by the decimal to find the savings
- Subtract the savings from the original price
Formula: Final Price = Original Price - (Original Price × Discount%)
Example: $50 shirt with 20% off
- $50 × 0.20 = $10 savings
- $50 - $10 = $40 final price
Double Discounts
Sometimes stores offer "additional percentage off" already discounted items. Be careful: 20% off plus an extra 20% off is NOT 40% off.
Example: $100 item
- First 20% off: $100 - $20 = $80
- Additional 20% off $80: $80 - $16 = $64
- Total savings: $36 (or 36%), not 40%
Common Discount Types
- Percentage Off: The most common type (e.g., "50% Off Everything")
- Buy One Get One (BOGO): Equivalent to 50% off if buying two identical items
- Fixed Amount Off: "$10 off purchase of $50+"
Tips for Smart Shopping
- Compare final prices, not just discount percentages
- Check if the discount applies to the pretax amount
- Look for coupons that can be stacked
