# Markup & Discount Calculator

Percent increase, percent change & percent off calculations

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

Enter non-zero values for any two of the five inputs.
Enter "0" (zero) for three unknown values.
At least one of the percentages must be zero.

Note: Whether you explicitly enter a markup or a discount percentage, the calculator always calculates the other. A user can't provide both. 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.

## Percentage 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.

## Percentage Change Calculator

### Implied Percentage

The percent increase and percent off are percent change calculations. And they have been presented above in a traditional way. For a percentage increase start with a net amount and increase it by a given percent or amount to find the gross amount. We can say the same about the percentage off example. We started with a gross amount and 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 someone who purchases items for resale and you want to make a 30% markup, start by entering the "Gross Amount," say \$49.95, and the "Percent Increase (markup)" 30%. The calculator will calculate the price you have to purchase the product for to make your markup.
