Calculation Steps
How the Discount Calculator Works
For a percentage discount, the discount amount is calculated by multiplying the original price by the discount rate.
Discount amount = Original price x Discount percentage / 100
The final price is then found by subtracting the discount amount from the original price.
Final price = Original price - Discount amount
For a fixed discount, the specified amount is subtracted directly from the original price.
For example, a $100 item with a 20% discount saves $20, leaving a final price of $80.
Frequently Asked Questions
How do I calculate a discount?
Multiply the original price by the discount percentage divided by 100. Subtract the resulting discount amount from the original price.
How do I calculate 20% off a price?
Multiply the original price by 0.20 to find the savings, then subtract the savings from the original price.
How do I find the final price after a discount?
Subtract the discount amount from the original price. For a percentage discount, the final price equals the original price multiplied by 1 minus the discount rate.
How do I find the original price from a discounted price?
Divide the final price by 1 minus the discount percentage expressed as a decimal. For example, divide by 0.80 for a 20% discount.
Are two 20% discounts the same as 40% off?
No. A second 20% discount is normally applied to the already reduced price. Two successive 20% discounts produce an effective discount of 36%.
Can I calculate a fixed amount discount?
Yes. Select Fixed Amount Off and enter the amount to subtract from the original price.
Does this calculator add tax?
Yes. Enter an optional tax percentage to calculate the amount after the discount and tax are applied.
