( 296.276 - 49.3 / 49.3) x 100 = 500.97%
Alternate method to calculate today's value of money after inflation - Using compound interest formula
Given that money changes over time due to inflation, which acts as compound interest, we can use the following formula:
FV = PV (1+i/100)^n
where,
- FV = Future value
- PV = Present value
- i: Average interest rate (inflation)
- n: Number of times the interest is compounded (i.e. # of years)
The future value in this case represents the amount obtained after applying the inflation rate to our initial value. In other words, it indicates how much $639900 is worth today. We have 48 years between 2022 and 1974. The average inflation rate was 3.8068547102846%.
Plugging in the values into the formula, we get:
639900 (1+ % 3.81/ 100 ) ^ 48 = $3845578.34
