Compare these numbers to the US's overall absolute change of $2,455,356.31 and total percent change of 551.77%.
CPI is the weighted combination of many categories of spending that are tracked by the government. This chart shows the average rate of inflation for select CPI categories between 1970 and 2018.
Compare these values to the overall average of 3.98% per year:
| Category | Avg Inflation (%) | Total Inflation (%) | $445,000 in 1970 → 2018 |
|---|---|---|---|
| Food | 3.96 | 546.20 | 2,875,595.68 |
| Shelter | 4.59 | 763.67 | 3,843,332.37 |
| Energy | 4.59 | 763.95 | 3,844,580.12 |
| Apparel | 1.59 | 113.33 | 949,296.47 |

| Medical care commodities | 4.48 | 721.29 | 3,654,754.43 |
It's important to note that not all categories may be tracked since 1970. This table and visualization use the earliest available data for each category.
This inflation calculator uses the following inflation rate formula:
Then plug in historical CPI values. The U.S. CPI was 38.8 in the year 1970 and 252.885 in 2018:
$445,000 in 1970 has the same "purchasing power" or "buying power" as $2,900,356.31 in 2018.
To get the total inflation rate for the 48 years between 1970 and 2018, we use the following formula:
Plugging in the values to this equation, we get:
The above data describe the CPI for all items. Also of note is the Core CPI, which measures inflation for all items except for the more volatile categories of food and energy. Core inflation averaged 3.91% per year between 1970 and 2018 (vs all-CPI inflation of 3.98%), for an inflation total of 529.97%.
When using the core inflation measurement, $445,000 in 1970 is equivalent in buying power to $2,803,372.44 in 2018, a difference of $2,358,372.44. Recall that for All Items, the converted amount is $2,900,356.31 with a difference of $2,455,356.31.
In 1970, core inflation was 6.25%.
The average inflation rate of 3.98% has a compounding effect between 1970 and 2018. As noted above, this yearly inflation rate compounds to produce an overall price difference of 551.77% over 48 years.
To help put this inflation into perspective, if we had invested $445,000 in the S&P 500 index in 1970, our investment would be nominally worth approximately $54,840,846.66 in 2018. This is a return on investment of 12,223.79%, with an absolute return of $54,395,846.66.
These numbers are not inflation adjusted, so they are considered nominal. In order to evaluate the real return on our investment, we must calculate the return with inflation taken into account.
The compounding effect of inflation would account for 84.66% of returns ($46,049,923.21) during this period. This means the inflation-adjusted real return of our $445,000 investment is $8,345,923.44.
| Original Amount | Final Amount | Change | |
|---|---|---|---|
| Nominal | $445,000 | $54,840,846.66 | 12,223.79% |
| Real Inflation Adjusted |
$445,000 | $8,345,923.44 | 1,875.49% |
Politics and news often influence economic performance. Here's what was happening at the time:
Raw data for these calculations comes from the Bureau of Labor Statistics' Consumer Price Index (CPI), established in 1913. Inflation data from 1665 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University.
