Sale Price vs Original Price
公式
How Discounts Are Calculated
Savings = Original Price × Discount% / 100
Sale Price = Original Price - Savings
Use this calculator anytime you see a percentage-off sale and want to know the exact dollar amount you will save and the final price you will pay at checkout. Keep in mind that discounts are applied before sales tax in most jurisdictions, so the tax is calculated on the reduced price, not the original.
计算示例
A $120 item at 25% off.
- 01Savings = $120 × 25% = $30
- 02Sale price = $120 - $30 = $90
常见问题
How do stacked discounts work?
When two discounts are applied sequentially (e.g., 20% off then 10% off), they are not additive. Apply the first discount, then apply the second to the reduced price.
How do I calculate the discount if I only know the original and sale price?
Subtract the sale price from the original price to get the savings amount, then divide by the original price and multiply by 100. For example, if an item dropped from $80 to $60, the discount is ($80 - $60) / $80 x 100 = 25%.
What is the difference between a discount and a markup?
A discount reduces the selling price for the buyer, while a markup increases the cost price to set a selling price for the seller. They are calculated from different bases: discounts from the retail price, markups from the wholesale cost.
