For all percentage increase (markup) and percent off (discount) calculations there are five potential variables. You may not always care about them, and in fact, you may not even be aware of them, but they are nonetheless there. Don't let this be off-putting. The user needs only provide values for two of the five, and the calculator will calculate the other three. More below
Whether you explicitly calculate a markup or a discount the other percentage is always implied (calculated). This is why a user can't enter both percentages. The results need to be kept in sync. A 10% increase is always 9.0909% off. That fact never changes.
Percentage Increase Calculator
To calculate a particular percentage increase, the user enters these two values
- Enter "Net Amount."
- Enter "Percent Increase (markup)."
- Set the other three inputs to 0.
To figure out what percentage an increase is, the user has these options
- Enter 0 for "Percent Increase (markup)."
- Enter the "Net Amount."
- And enter either "Amount Added/Subtracted" or "Gross Amount."
- Set the other inputs to 0.
Percent Off Calculator
To calculate a particular percent off, the user enters these two values
- Enter "Gross Amount."
- Enter "Percent Off (discount)."
- Set the other three inputs to 0
To figure out what percent off a discount is, the user has these options
- Enter 0 for "Percent Off (discount)."
- Enter the "Gross Amount."
- And enter either "Amount Added/Subtracted" or "Net Amount."
- Set the other inputs to 0.
Percent Change Calculator
The percent increase and percent off are percent change calculations. And they have been presented above in the classic way. For a percentage increase start with a net amount and increase it by a given percent or amount to find the gross amount. The same can be said about the percentage off example. We started with a gross amount an deducted either an amount or a percentage.
These are traditional examples. But this calculator allows the user to provide what is normally the implied percentage in the traditional example and the calculator will calculate the percentage that the user usually provides.
What does this mean?
I'll tell you.
Take a percent increase calculation. Rather than provide a "Net Amount" and "Amount Added/Subtracted", the user can provide the "Gross Amount" instead of the "Net Amount" and the calculator will still calculate the "Percent Increase (markup)."
What is the benefit of this?
Well, there are several uses for being able to calculate a percent change from the reverse of the traditional perspective. If, for example, you are somone who purchases items for resale and you know a product can sell for say $49.95 and you want to make a 30% markup, by entering the "Gross Amount" and the "Percent Increase (markup)", the calculator will calculate the amount you have to purchase the product for to make your markup.
Markup & Discount Calculator Help
In some businesses, accountants and other managers have to simultaneously work with both markups (cost or net amount plus a percentage) and discounts or mark-downs (a total or gross amount less a percentage). The five values you see can be either a user input or a calculated result. This calculator allows you to calculate three values by entering just two values.
Either Net Amount is the amount before adding the markup, or it is the amount after calculating the discount.
Markup percentage is the percentage added to the net amount. $100 plus a 5.0% markup results in a Gross Amount of $105.
The Amount is $5.00, that is the difference between the Net Amount and the Gross Amount.
The Discount Percent is the percentage deducted from the Gross Amount. $105 minus a 5.0% discount equals a Net Amount of $99.75. (The Amount is $5.25).
Either the "Gross amount" is the amount before deducting the discount, or it is the amount after calculating the markup.
Example 1: You purchased 1,000 shares of stock for a total price of $23,554.00. Enter this in the "Gross Amount". You later sold the stock for a loss, and you received only $19,054.00. Enter this in the "Net Amount." Click [Calc]. The Discount Percentage is your percentage lost, i.e., 19.1%. The Markup Percentage is the percentage you have to earn on a trade to make up the loss, i.e., 23.6%. This calculation assumes you are will to reinvest the entire $19,054.
Example 2: Sales tax is a markup percentage. That is, we add sales tax to the net amount. If you want to sell or advertise an item at a price that includes sales tax, you cannot use the sales tax rate (percentage) to calculate a deduction from the sale price to know the net selling price. To calculate the net sale price, enter the total gross price, including the tax amount that you want to sell the item for in the Gross Amount - say $495.00. Enter the sales tax rate into the Markup Percentage, say 7%. Set the other three inputs (Net Amount, Amount, and Discount Percentage) to 0.0. Calculate.
The Net Amount, before sales tax is $462.62 and the Amount (the sale tax in this case) is $32.38
Example 3: You can use the calculator to calculate the net purchase amount assuming a known markup. If you can sell an item for $75 and you want to make a 30% markup, what price do you have to pay for the item? Enter $75.00 for "gross amount" and 30% for the "markup percent". You have to buy at $57.69. The profit (or difference) is $17.31, and the markdown percent is 23.08%. You can use this to calculate the buy-to-cover price for a short position if you cover base on a profit goal.
