Sale Price Calculator

How to Calculate Sale Prices

Calculating sale prices is essential for smart shopping. The basic formula is simple: Sale Price = Original Price × (1 - Discount%). For example, if an item costs $100 and has a 20% discount, the sale price would be $100 × (1 - 0.20) = $80. This calculator automates the process and even handles stacked discounts for maximum savings.

Understanding Stacked Discounts

Stacked discounts (also called cascading discounts) occur when multiple discounts are applied sequentially. For example, "50% off + extra 20% off" doesn't mean 70% off total. Instead:

• Original Price: $100
• After 50% off: $100 × 0.50 = $50
• After extra 20% off: $50 × 0.80 = $40
• Total Discount: 60% (not 70%!)

Common Discount Scenarios

Here are some common discount scenarios you'll encounter while shopping:

• Buy One Get One (BOGO): Effectively 50% off when buying 2 items
• Buy 2 Get 1 Free: Effectively 33% off when buying 3 items
• Seasonal Sales: Typically 20-50% off regular prices
• Clearance Sales: Often 50-70% off to clear inventory
• Member Discounts: Additional 10-20% off for loyalty members
• Coupon Stacking: Combine store coupons with manufacturer coupons

Tips for Maximum Savings

To get the best deals while shopping:

• Compare final prices: A higher discount % doesn't always mean a better deal
• Check unit prices: Compare price per unit/weight, not just total price
• Time your purchases: End-of-season and holiday sales offer the best discounts
• Use cashback apps: Stack cashback with sale prices for extra savings
• Sign up for newsletters: Get exclusive discount codes via email
• Price match: Many stores will match competitors' lower prices
