Calculate final price after discount, markup or tax. See discount savings, gross spread or tax added; gross spread excludes other expenses.

Find the discounted price, with optional tax.

Discount mode applies tax after the discount. Enter the applicable tax rate; presets are examples, with no jurisdiction or tax rules assumed.

Optional settings

Optional; blank means no tax.

Final Price Formula

The following formula applies one signed percentage change. In Sale price mode, enter the discount as a positive percentage, equivalent to a negative C below. Optional tax is then applied to the discounted price: FP = IP(1 – discount/100)(1 + tax/100). Markup and tax modes use a positive C for an increase.

FP = IP(1 + C / 100)
  • Where FP is the Final Price ($)
  • IP is the initial price ($) 
  • C is the percentage change (%). Use a positive value for an increase and a negative value for a decrease.

How to Calculate Final Price?

The following example problems outline how to calculate Final Price.

Example Problem #1:

  1. First, determine the initial price ($).
    1. The initial price ($) is given as 40.
  2. Next, determine the percentage change (%).
    1. The percentage change (%) is provided as -30 (a 30% decrease).
  3. Finally, calculate the Final Price using the equation above: 

FP = IP(1 + C/100)

The values given above are inserted into the equation below:

FP = 40(1 + (-30)/100) = 28 ($)

Example Problem #2: 

For this problem, the variables needed are provided below:

initial price ($) = 50

percentage change (%) = 70 (a 70% increase)

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. 

FP = IP(1 + C/100) = ?
