The cumulative inflation rate in the United States between 1968 and today has been 865.56%, meaning that prices are 9.7 times higher than they were in 1968. In practical terms, the purchasing power of $26M in 1968 is equivalent to $251.04 million in today's dollars. The average annual inflation rate over this period has been 4.06%.
The chart below shows how the value of $26M changes over time when adjusted for inflation, based on Consumer Price Index (CPI) data. All values are equivalent in terms of purchasing power, indicating how much money would be needed each year to buy the same goods or services.
All calculations are performed in US dollars with six-decimal precision, though displayed values are rounded to two decimals for readability. Inflation figures are sourced from official government and international reports released monthly. To convert historical amounts into today's dollars, we use the most recent CPI data available and extrapolate it to estimate the CPI for today.
The following table contains relevant indicators:
| Indicator | Value |
|---|---|
| Cumulative inflation 1968-2024 | 801.84% |
| Cumulative inflation 1968-today | 865.56% |
| Avg. annual inflation 1968-2024 | 4.01% |
| CPI 1968 | 34.78 |
| CPI 2024 | 313.69 |
| CPI Aug 2026 (latest official data) | 334.98 |
| CPI today | 335.85 |
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 1968 and 2024, use the corresponding CPI values:
To obtain the equivalent value today (present value), plug in the CPI for today, which is estimated as 335.85:
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 are $26M worth today. There are 56 years between 1968 and 2024 and the average inflation rate was 4.0054%. Therefore, we can resolve the formula like this:
