How Purchasing Power Gain Calculator Works?
The Purchasing Power Gain Calculator works by comparing real salary after the raise with the starting salary.
Enter salaries
Type the starting salary and the salary after the raise.
Enter inflation
Type inflation from the start date to the date of the new salary.
Compute the gain
The calculator deflates the new salary and subtracts the old salary.
Express in goods
Type an item price, such as a $250 weekly grocery basket, to see the extra units bought.
Purchasing Power Gain Calculator Formula
The Purchasing Power Gain formula subtracts the old salary from the deflated new salary.
Gain $ = New Salary ÷ (1 + π) − Old Salary
Extra Units = Gain $ ÷ Item Pricestart
Variables
- π
- Inflation over the period
- Item Pricestart
- Price of the chosen item at the start
Worked example
A salary rising from $70,000 to $76,000 during 4% inflation produces a real gain of $3,077, equal to 12.3 extra $250 grocery baskets per year.
