Q&A for How to Calculate a Discount

Assuming you know the original price and the sale price of an item, subtract sale price from original price to determine the discount amount. Next, divide the discount amount by original price. Convert this decimal amount into a percentage. This percent is the discount rate. For an example, a lamp shows a discount price of $30 with an original price of $50. $50 - $30 = $20 20 / 50 = 0.40 0.40 = 40%

If the product regular price is $425 and the discounted price is $318.75. Divide the disc. price to orig. price EX. 318.75 / 425= 0.75, then multiply the 0.75 into 100 and 100 is the total % of an item Ex. 0.75x100= 75, now subtract the 100 to 75 . Ex. 100- 75= 25%. So the discount rate is = 25%.

Yes, as long as your conversion is right.

Divide by the percent discounted, taken from 100%. Say an item on 20% discount has a price tag reading £40. 100% - 20% is 80%. £40 / 0.8 = £50. (The answer, 80% of £50 is £40).

if something costs $100, multiply the total amount being 100 by the amount of 2.5 percent after moving the decimal over two spaces to the left. So, it should look like $100 times .025 equals $2.50.

Once you calculate the discount, you just need to subtract it from the original price to get the sale price. For example, if the cost of the item $80 and it is on sale for 20% off, change 20% to a decimal by moving the decimal point two spaces to the left. Multiply the original price by .20 (80×.20=16). Then, subtract the answer from the original price (80-16=64). This gives you the final sale price of $64.

Divide the original price by the sale price (200/250=0.8). Multiply your answer by 100 (0.8×100=80). Then subtract that answer from 100 (100-80=20). So you end up with the percentage of the discount, which is 20%.

Subtract the discount from 100 percent, then divide that by the discounted price.

if it is a percentage, the denominator will always be 100. then you put the percentage discount as the numerator. example: the percentage discount is 20%. the fraction will be 20/100.

Simply divide the new price by the old price. 272 / 425 = 0.64 (this the actual percentage of monies you are paying compared to the original price). Now subtract the value obtained above, from 11 - 0.64 = 0.36. The result also reads as 36 %.

Take 100% and subtract 15%. You get 85%. Multiply that by $90. That's $76.50.

You would pay (100% - 40%) = 60% of the original price.
