The Discount Calculator is a versatile savings tool that helps you calculate final prices after percent-off or fixed-amount discounts. Whether you're shopping during a sale, negotiating prices, or planning a budget, this calculator instantly computes savings, discounted prices, and equivalent discount rates. Perfect for retail shopping, business pricing decisions, and personal finance management.
Discount calculations determine the reduced price after applying either a percentage reduction or a fixed dollar amount reduction. The calculator works in both directions — given any two values, it computes the third.
Where:
• Original Price = The initial price before any discount.
• Discount% = The percentage taken off the original price.
• Final Price = The price after applying the discount.
• Savings = Original Price − Final Price
Fixed Discount Formula:
The discount amount is subtracted directly from the original price. The equivalent discount percentage can also be calculated: Discount% = (Discount Amount / Original Price) × 100%.
Pfinal = Poriginal × (1 − d/100)
Pfinal = Poriginal − D
S = Poriginal − Pfinal
Percent Discount Example: A jacket originally priced at $80 is on sale for 25% off.
You pay $60 instead of $80, saving 25% or $20 on your purchase.
Fixed Amount Discount Example: A laptop priced at $1,200 has a $150 store credit discount.
You save $150, which is equivalent to a 12.5% discount off the original price.
Finding Discount% from Final Price: A $200 item is on clearance for $140. What's the discount percentage?
The item has a 30% discount, saving you $60 on the original price.
Tip: Always compare the final price, not just the discount percentage, as a high percentage on a low-priced item may save less than a moderate percentage on an expensive item.

Subtract a percentage from the original price. Example: 10% off $45 = $45 × 0.90 = $40.50. You save $4.50.
Subtract a specific dollar amount. Example: $20 off $95 = $75. You save exactly $20.
Final Price = Original Price × (1 - Discount%/100)
Savings = Original Price - Final Price
For multiple discounts (e.g., 20% + 15% off), use the Percent Off Calculator for sequential calculations.
