The discount calculator will instantly show the final price and the actual amount of savings.
**Formula:** Total price = Price × (1 - Discount/100)
Example: product for 3,000 ₽ with a 25% discount → 3,000 × 0.75 = 2,250 ₽
**Formula:** Discount = (1 - Discount Price / Original Price) × 100
Example: it was 4,000 ₽, now it is 3,200 ₽ → (1 - 3200/4000) × 100 = 20%
Important: discounts do not add up, but are multiplied!
| Discounts | Apparent benefit | Real benefit |
|---|---|---|
| 20% + 10% | 30% | 28% |
| 30% + 20% | 50% | 44% |
| 50% + 30% | 80% | 65% |
Total discount = 1 - (1 - A/100) × (1 - B/100), where A and B are the discount amounts.
Discount reduces the price immediately
Cashback returns part of the amount later
With the same percentage, the discount is more profitable, since it works immediately
