The inflation rate in the United States between 1999 and 2020 was 55.37%, which translates into a total increase of $0.55. This means that 1 dollars in 1999 are equivalent to 1.55 dollars in 2020. In other words, the purchasing power of $1 in 1999 equals $1.55 in 2020. The average annual inflation rate between these periods was 2.12%.
The following chart depicts the equivalence of $1 due to compound inflation and CPI changes. All values are equivalent in terms of purchasing power, which means that for each year the same goods or services could be bought with the indicated amount of money.
All calculations are performed in the local currency (USD) and using 6 decimal digits. Results show only up to 2 decimal digits to favour readability. Inflation data is provided by governments and international institutions on a monthly basis.
The following table contains relevant indicators:
| Indicator | Value |
|---|---|
| Cumulative inflation from 1999 to 2020 | 55.37% |
| Avg. Annual inflation from 1999 to 2020 | 2.12% |
| CPI 1999 | 166.58 |
| CPI 2020 | 258.81 |
There are several ways to calculate the time value of money. Depending on the data available, results can be obtained by using the Consumer Price Index (CPI) formula or the compound interest formula.
When we have both the start and end years, we can use the following formula:
To obtain the values equivalent in buying power between 1999 and 2020, use the corresponding CPI values:
Given that money changes with time as a result of an inflation rate that acts as compound interest, we can use the following formula: FV = PV × (1 + i)n, where:
In this case, the future value represents the final amount obtained after applying the inflation rate to our initial value. In other words, it indicates how much is $1 worth today. There are 21 years between 1999 and 2020 and the average inflation rate was 2.1205%. Therefore, we can resolve the formula like this:
