To calculate the percentage discount from an original price and a sale price, you can use a formula that divides the difference by the original price. In the example shown, the formula in E5, copied down, is:
In this example, the goal is to determine the percentage discount for each item shown in the table, given an original price and a sale price. In other words, given the Charcoal grill has an original price of $70.00 and a Sale Price of $59.50, we want to calculate a percentage discount of 15%, based on a price decrease of $10.50. Note that a discount of 15% represents the the price change ($10.50) expressed as a percentage of the original price. To solve for the percentage when the price change is known, we can use a general formula like this:
However, since the price change is not in the table as a separate column, we need to add a step:
Applying this approach to the worksheet as shown, the formula in cell E5, copied down, is:
For each item in the table, Excel returns a calculated percentage.
Formatting percentages in Excel
In mathematics, a percentage is a number expressed as a fraction of 100. For example, 75% is read as "Seventy-five percent" and is equivalent to 75/100 or 0.75. Accordingly, the values in column E are decimal values. To display these numbers as a percentage with the percent sign (%), the Percentage number format has been applied to E5:E15.
In this example, the goal is to work out the total of all expenses using a known percent of total of any one expense . If we know groceries are $200 and we know groceries represent 10.3% of total expenses, we want to calculate the total of all...
In this example, the goal is to increase the prices shown in column C by the percentages shown in column D. For example, given the original price of $70.00, and an increase of 10%, the result should be $77.00. The general formula for this...
In this example, the goal is to decrease the prices shown in column C by the percentages shown in column D. For example, given an original price of $70.00, and an decrease of 10% ($7.00), the result should be $63.00. The general formula for this...
In this example, the goal is to determine the original price from a discounted price (sale price) and the percentage discount. For example, given a sale price of $60.00, and a discount of 10%, we want a result of $70.00 for the original price. The...
This formula uses the MIN function to make a decision that might otherwise be handled with the IF function . Although MIN is usually used to return the minimum value in a data set with many numbers, it also works fine for "lesser of the two"...
In this example, the goal is to calculate and display profit margin as a percentage for each of the items shown in the table. In other words, given a price of $5.00 and a cost of $4.00, we want to return a profit margin of 20%. Each item in the...
