Discount Calculation Formula Explained
To understand how the tool works, it’s important to know the basic discount formulas behind it.
1. Discount Amount Formula:
Discount Amount = (Original Price × Discount %) ÷ 100
2. Final Price Formula:
Final Price = Original Price − Discount Amount
Example Breakdown:
If the original price is $200 and the discount is 30%:
- Discount Amount = (200 × 30) ÷ 100 = $60
- Final Price = 200 − 60 = $140
So, you save $60 instantly.
