Quick answer
How do you calculate a sale price after a discount?
Multiply the original price by (1 - discount ÷ 100): sale price = original price × (1 - discount ÷ 100). The saving is original price × discount ÷ 100. Example: an item at €80 with 30% off costs 80 × 0.7 = €56, a saving of €24. Conversely, the discount rate is (original price - sale price) ÷ original price × 100.
| Discount on €80 | Saving | Sale price |
|---|---|---|
| 10% | €8 | €72 |
| 20% | €16 | €64 |
| 30% | €24 | €56 |
| 40% | €32 | €48 |
| 50% | €40 | €40 |
| 70% | €56 | €24 |
About the Sales and Discounts Calculator
What is it?
The sales and discount calculator is a comprehensive tool for managing promotional pricing: calculate a sale price from a discount, find the discount percentage between two prices, or analyze your commercial margins.
Why use it?
Essential for e-commerce businesses during sales periods, Black Friday or any commercial discount calculation. Avoid pricing errors that can impact your margins.
How does it work?
Three modes: (1) Sale price = Original price × (1 - discount %), (2) Discount % = (Original - Sale) ÷ Original × 100, (3) Margin = (Selling price - Cost) ÷ Selling price × 100.
Usage tips
- Always check a discount's impact on your margin before offering it
- A 20% discount on a 30% margin reduces your profit by more than 65%
- During sales, clearly display the crossed-out price and sale price
- Use the margin to set a floor price below which you won't go
