Markup & Discount Calculator

For all percentage increase (markup) and percent off (discount) calculations, there are five possible variables. You may not always need them, and you may not even be aware of them, but they are always present. Do not let this discourage you. The user provides values for only two of the five, and the calculator computes the remaining three. More below…

To calculate a specific percentage increase, enter these values:

• Enter “Net Amount.”
• Enter “Percent Increase (markup).”
• Set the other three inputs to 0.

To determine what percentage an increase represents, use one of the following setups:

• Enter 0 for “Percent Increase (markup).”
• Enter the “Net Amount.”
• Enter either “Amount Added/Subtracted” or “Gross Amount.”
• Set the remaining inputs to 0.

To calculate a specific percent off, enter these values:

• Enter “Gross Amount.”
• Enter “Percent Off (discount).”
• Set the other three inputs to 0.

To determine what percent off a discount represents, use one of the following setups:

• Enter 0 for “Percent Off (discount).”
• Enter the “Gross Amount.”
• Enter either “Amount Added/Subtracted” or “Net Amount.”
• Set the remaining inputs to 0.

Implied Percentage

Percent increase and percent off are both percentage change calculations. The examples above use the traditional approach. For a percentage increase, you begin with a net amount and increase it by a percentage or an amount to get the gross amount. For a percentage off, you start with a gross amount and subtract either a percentage or an amount.

These are conventional examples. This calculator also lets you enter what is usually the implied percentage in those examples, and it will compute the percentage that is normally provided.

What does this mean?
