How to calculate the inflated value of $100 in 1977
To calculate the change in value between 1977 and today, we use the following inflation rate formula:
CPI Today / CPI in 1977 x USD Value in 1977 = Current USD Value
By plugging the values into the formula above, we get:
296.276/ 60.6 x $100 = $488.9
To buy the same product that you could buy for $100 in 1977, you would need $488.9 in 2022.
To calculate the cumulative or total inflation rate in the past 45 years between 1977 and 2022, we use the following formula:
CPI in 2022 - CPI in 1977 / CPI in 1977 x 100 = Cumulative Inflation Rate
By inserting the values to this equation, we get:
( 296.276 - 60.6 / 60.6) x 100 = 388.9%
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 $100 is worth today. We have 45 years between 2022 and 1977. The average inflation rate was 3.5895831674542%.
Plugging in the values into the formula, we get:
100 (1+ % 3.59/ 100 ) ^ 45 = $488.9
