Quick Assumptions
- ▸ Discount amount = original price × discount % ÷ 100.
- ▸ Sale price = original price − discount amount.
- ▸ Savings percentage equals the discount percentage.
- ▸ Effective price ratio = sale price ÷ original price.
How a percentage discount actually works
A percentage discount reduces the original price by a fixed proportion. A 25% discount means you pay 75% of the original price — the other 25% is what you save. Knowing both the sale price and the savings makes it easier to compare deals, check receipts, and decide whether a discount is genuinely worth it.
🏷️ Percentage off
The discount rate is applied directly to the original price to work out how much is taken off.
💰 Money saved
The discount amount is the difference between the original price and what you actually pay.
🧾 Final sale price
The price after the discount is the amount you hand over at checkout before tax or shipping.
📊 Effective ratio
The ratio of sale price to original price shows what fraction of the price you still pay.
🔁 Stacked discounts
Two 10% discounts do not equal 20% off — they compound, so the effective saving is lower than it looks.
🧮 Reverse checking
Given a sale price and original price, you can work backwards to find the percentage discount applied.
