Buying power of $1 in 1991
If you had $1 in your hand in 1991, its adjusted value for inflation today would be $2.18. Put another way, you would need $2.18 to beat the rising inflation. When $1 becomes equivalent to $2.18 over time, the "real value" of a single US dollar decreases. In other words, a dollar will pay for fewer items at the store.
This effect explains how inflation gradually erodes the value of a dollar. By calculating the value in 1991 dollars, it's evident how $1 loses its worth over 31 years.

How to calculate the inflated value of $1 in 1991
To calculate the change in value between 1991 and today, we use the following inflation rate formula:
CPI Today / CPI in 1991 x USD Value in 1991 = Current USD Value
By plugging the values into the formula above, we get:
296.276/ 136.2 x $1 = $2.18
To buy the same product that you could buy for $1 in 1991, you would need $2.18 in 2022.
To calculate the cumulative or total inflation rate in the past 31 years between 1991 and 2022, we use the following formula:
CPI in 2022 - CPI in 1991 / CPI in 1991 x 100 = Cumulative Inflation Rate
By inserting the values to this equation, we get:
( 296.276 - 136.2 / 136.2) x 100 = 117.53%
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 $1 is worth today. We have 31 years between 2022 and 1991. The average inflation rate was 2.5386797802141%.
Plugging in the values into the formula, we get:
1 (1+ % 2.54/ 100 ) ^ 31 = $2.18
