How to Calculate Discounts

Whether you're running a flash sale, seasonal promotion, or clearance event, knowing exactly how discounts affect your pricing and profit is essential.

This calculator helps you determine sale prices, the discount percentage between two prices, and how much customers save.

E-commerce Discount Strategy

  • 10-15% off: Gentle nudge — good for welcome offers and newsletter sign-ups
  • 20-30% off: Meaningful discount — seasonal sales, holiday promotions
  • 40-50% off: Major sale — clearance, BFCM, end-of-season
  • Buy X Get Y: Increases AOV while protecting margins
  • Free Shipping: Often more effective than percentage discounts

Pro Tips for Profitable Discounts

  1. Never discount below your break-even point — Know your minimum viable price
  2. Use "$ off" for expensive items — "$50 off" feels bigger than "10% off" on a $500 item
  3. Use "% off" for cheap items — "25% off" feels bigger than "$5 off" on a $20 item
  4. Bundle instead of discount — "Buy 2 Get 1 Free" preserves perceived value better than "33% off"
