If a price dropped 20% and then rose 20%, is it back where it started?
No, it is 4% below. A 100 item falls to 80, and a 20% rise on 80 is only 16, taking it to 96. The two percentages are applied to different bases, which is why they do not cancel. It takes a 25% rise to undo a 20% cut.
How do I apply two discounts at once?
Run them in sequence. Enter the original price with the first discount, take the final price it returns, and put that into the price field for the second discount. Multiplying is the right model: 20% then 10% is a 28% total reduction, not 30%.
Does the discount come before or after sales tax?
Before, in almost every jurisdiction. Tax is charged on what you actually pay, so a 25% discount on an 80 item leaves 60, and tax is assessed on the 60. Calculate the discount here first, then add tax.
How do I find the original price from a sale price?
Divide the sale price by 1 minus the discount as a decimal. A 60 item that was 25% off originally cost 60 / 0.75 = 80. This tool runs forward only, so that division is a manual step.
How much is 20 percent off 50?
40.00, and you save 10.00. Twenty percent is one fifth, so the quick check is to divide by 5 and subtract.
What is 30 percent off 120?
84.00, with a saving of 36.00. Ten percent of 120 is 12, so three of those is the 36 that comes off.
What is 15 percent off 60?
51.00, a saving of 9.00. Enter 60 as the original price and 15 as the discount and both lines appear as you type.
How do I calculate an extra percent off an already reduced price?
Apply them one after the other, not by adding the percentages. Run the first discount, copy the final price into the original price field, and apply the second. An extra 20 percent off a price already cut 20 percent is a 28 percent total reduction, so a 100 item ends at 72.
Can it do a fixed amount off instead of a percentage?
No, the discount field is a percentage. To convert a fixed amount, divide it by the original price and multiply by 100: 20 off an 80 item is a 25% discount.
