## Value of \$300 from 2017 to 2020

According to the Bureau of Labor Statistics consumer price index, today's prices in 2020 are 6.04% higher than average prices since 2017. The U.S. dollar experienced an average inflation rate of 1.97% per year during this period, causing the real value of a dollar to decrease.

In other words, \$300 in 2017 is equivalent in purchasing power to about \$318.11 in 2020, a difference of \$18.11 over 3 years.

The 2017 inflation rate was 2.13%. The current year-over-year inflation rate (2019 to 2020) is now 1.31%1. If this number holds, \$300 today will be equivalent in buying power to \$303.93 next year. The current inflation rate page gives more detail on the latest official inflation rates.

## Buying power of \$300 in 2017

This chart shows a calculation of buying power equivalence for \$300 in 2017 (price index tracking began in 1635).

For example, if you started with \$300, you would need to end with \$318.11 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$300 is equivalent to \$318.11 over time, that means that the "real value" of a single U.S. dollar decreases over time. In other words, a dollar will pay for fewer items at the store.

This effect explains how inflation erodes the value of a dollar over time. By calculating the value in 2017 dollars, the chart below shows how \$300 is worth less over 3 years.

According to the Bureau of Labor Statistics, each of these USD amounts below is equal in terms of what it could buy at the time:

## Inflation by City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 2017 to 2020 (figures shown are purchasing power equivalents of \$300):

San Diego, California experienced the highest rate of inflation during the 3 years between 2017 and 2020 (4.51%).

St Louis, Missouri experienced the lowest rate of inflation during the 3 years between 2017 and 2020 (1.02%).

Note that some locations showing 0% inflation may have not yet reported latest data.

## Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £300.00 in 2017 would be equivalent to £317.68 in 2020, an absolute change of £17.68 and a cumulative change of 5.89%.

In Canada, CA\$300.00 in 2017 would be equivalent to CA\$313.80 in 2020, an absolute change of CA\$13.80 and a cumulative change of 4.60%.

Compare these numbers to the US's overall absolute change of \$18.11 and total percent change of 6.04%.

## Inflation by Spending Category

CPI is the weighted combination of many categories of spending that are tracked by the government. Breaking down these categories helps explain the main drivers behind price changes. This chart shows the average rate of inflation for select CPI categories between 2017 and 2020.

Compare these values to the overall average of 1.97% per year:

Category Avg Inflation (%) Total Inflation (%) \$300 in 2017 → 2020
Food and beverages 2.04 6.24 318.72
Housing 2.54 7.82 323.46
Apparel -1.95 -5.72 282.83
Transportation -0.18 -0.54 298.38
Medical care 2.88 8.90 326.71
Recreation 0.95 2.89 308.67
Education and communication 0.81 2.46 307.37
Other goods and services 2.17 6.66 319.98

## How to Calculate Inflation Rate for \$300 since 2017

Our calculations use the following inflation rate formula to calculate the change in value between 2017 and today:

CPI today CPI in 2017
×
2017 USD value
=
Today's value

Then plug in historical CPI values. The U.S. CPI was 245.12 in the year 2017 and 259.918 in 2020:

259.918245.12
×
\$300
=
\$318.11

\$300 in 2017 has the same "purchasing power" or "buying power" as \$318.11 in 2020.

To get the total inflation rate for the 3 years between 2017 and 2020, we use the following formula:

CPI in 2020 - CPI in 2017CPI in 2017
×
100
=
Cumulative inflation rate (3 years)

Plugging in the values to this equation, we get:

259.918 - 245.12245.12

=
6%

## Alternate Measurements of Inflation

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 1.91% per year between 2017 and 2020 (vs all-CPI inflation of 1.97%), for an inflation total of 5.84%.

When using the core inflation measurement, \$300 in 2017 is equivalent in buying power to \$317.53 in 2020, a difference of \$17.53. Recall that for All Items, the converted amount is \$318.11 with a difference of \$18.11.

In 2017, core inflation was 1.84%.

Chained CPI is an alternative measurement that takes into account how consumers adjust spending for similar items. Chained inflation averaged 1.38% per year between 2017 and 2020, a total inflation amount of 5.84%.

According to the Chained CPI measurement, \$300 in 2017 is equal in buying power to \$312.58 in 2020, a difference of \$12.58 (versus a converted amount of \$318.11/change of \$18.11 for All Items).

In 2017, chained inflation was 1.76%.

## Comparison to S&P 500 Index

The average inflation rate of 1.97% has a compounding effect between 2017 and 2020. As noted above, this yearly inflation rate compounds to produce an overall price difference of 6.04% over 3 years.

To help put this inflation into perspective, if we had invested \$300 in the S&P 500 index in 2017, our investment would be nominally worth approximately \$469.96 in 2020. This is a return on investment of 56.65%, with an absolute return of \$169.96 on top of the original \$300.

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 5.69% of returns (\$26.76) during this period. This means the inflation-adjusted real return of our \$300 investment is \$143.21. You may also want to account for capital gains tax, which would take your real return down to around \$122 for most people.

Investment in S&P 500 Index, 2017-2020
Original Amount Final Amount Change
Nominal \$300 \$469.96 56.65%
Real
\$300 \$443.21 47.74%

Information displayed above may differ slightly from other S&P 500 calculators. Minor discrepancies can occur because we use the latest CPI data for inflation, annualized inflation numbers for previous years, and we compute S&P price and dividends from January of 2017 to latest available data for 2020 using average monthly close price.
