How to calculate the inflated value of $40900 in 1970

To calculate the change in value between 1970 and today, we use the following inflation rate formula:

CPI Today / CPI in 1970 x USD Value in 1970 = Current USD Value

By plugging the values into the formula above, we get:

296.276/ 38.8 x $40900 = $312311.56

To buy the same product that you could buy for $40900 in 1970, you would need $312311.56 in 2022.

To calculate the cumulative or total inflation rate in the past 52 years between 1970 and 2022, we use the following formula:

CPI in 2022 - CPI in 1970 / CPI in 1970 x 100 = Cumulative Inflation Rate

By inserting the values to this equation, we get:

( 296.276 - 38.8 / 38.8) x 100 = 663.6%

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 $40900 is worth today. We have 52 years between 2022 and 1970. The average inflation rate was 3.9867890825727%.

Plugging in the values into the formula, we get:

40900 (1+ % 3.99/ 100 ) ^ 52 = $312311.56
