$1,000 in 2010 is worth $1,186.90 in 2020

Buying power of $1,000 in 2010

This chart shows a calculation of buying power equivalence for $1,000 in 2010 (price index tracking began in 1635).

For example, if you started with $1,000, you would need to end with $1,186.90 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1,000 is equivalent to $1,186.90 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 2010 dollars, the chart below shows how $1,000 is worth less over 10 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:

This conversion table shows various other 2010 amounts in 2020 dollars, based on the 18.69% change in prices:

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 £1,000.00 in 2010 would be equivalent to £1,306.14 in 2020, an absolute change of £306.14 and a cumulative change of 30.61%.

In Canada, CA$1,000.00 in 2010 would be equivalent to CA$1,175.94 in 2020, an absolute change of CA$175.94 and a cumulative change of 17.59%.

Compare these numbers to the US's overall absolute change of $186.90 and total percent change of 18.69%.

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.

Between 2010 and 2020:

• Gas prices increased from $2.73 per gallon to $2.57
• Bread prices increased from $1.36 per loaf to $1.35
• Egg prices increased from $1.79 per carton to $1.46
• Chicken prices increased from $1.27 per per 1 lb of whole chicken to $1.41
• Electricity prices increased from $0.12 per KwH to $0.13

This chart shows the average rate of inflation for select CPI categories between 2010 and 2020.

Compare these values to the overall average of 1.73% per year:

How to calculate inflation rate for $1,000, 2010 to 2020

Our calculations use the following inflation rate formula to calculate the change in value between 2010 and 2020:

Then plug in historical CPI values. The U.S. CPI was 218.056 in the year 2010 and 258.81166666667 in 2020:

$1,000 in 2010 has the same "purchasing power" or "buying power" as $1,186.90 in 2020.

To get the total inflation rate for the 10 years between 2010 and 2020, we use the following formula:

Plugging in the values to this equation, we get:

Alternate Measurements of Inflation

There are multiple ways to measure inflation. Published rates of inflation will vary depending on methodology. The Consumer Price Index, used above, is the most common standard used globally.

Alternative measurements are sometimes used based on context and economic/political circumstances. Below are a few examples of alternative measurements.

Personal Consumption Expenditures (PCE) Inflation

The PCE Price Index is the U.S. Federal Reserve's preferred measure of inflation, compiled by the Bureau of Economic Analysis. It measures the change in prices of goods and services purchased by consumers.

The PCE Price Index changed by 1.46% per year on average between 2010 and 2020. The total PCE inflation between these dates was 15.61%. In 2010, PCE inflation was 1.79%.

This means that the PCE Index equates $1,000 in 2010 with $1,156.08 in 2020, a difference of $156.08. Compare this to the standard CPI measurement, which equates $1,000 with $1,186.90. The PCE measured -3.08% inflation compared to standard CPI.

For more information on the difference between PCE and CPI, see this analysis provided by the Bureau of Labor Statistics.

Core Inflation

Also of note is the Core CPI, which uses the standard CPI but omits the more volatile categories of food and energy.

Core inflation averaged 1.92% per year between 2010 and 2020 (vs all-CPI inflation of 1.73%), for an inflation total of 20.94%. In 2010, core inflation was 0.96%.

When using the core inflation measurement, $1,000 in 2010 is equivalent in buying power to $1,209.44 in 2020, a difference of $209.44. Recall that the converted amount is $1,186.90 when all items including food and energy are measured.

Chained Inflation

Chained CPI is an alternative measurement that takes into account how consumers adjust spending for similar items. Chained inflation averaged 1.48% per year between 2010 and 2020, a total inflation amount of 15.79%.

According to the Chained CPI measurement, $1,000 in 2010 is equal in buying power to $1,157.90 in 2020, a difference of $157.90 (versus a converted amount of $1,186.90/change of $186.90 for All Items).

In 2010, chained inflation was 1.42%.

Comparison to S&P 500 Index

The average inflation rate of 1.73% has a compounding effect between 2010 and 2020. As noted above, this yearly inflation rate compounds to produce an overall price difference of 18.69% over 10 years.

To help put this inflation into perspective, if we had invested $1,000 in the S&P 500 index in 2010, our investment would be nominally worth approximately $4,186.55 in 2020. This is a return on investment of 318.65%, with an absolute return of $3,186.55 on top of the original $1,000.

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 15.75% of returns ($659.27) during this period. This means the inflation-adjusted real return of our $1,000 investment is $2,527.28. You may also want to account for capital gains tax, which would take your real return down to around $2,148 for most people.

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 2010 to latest available data for 2020 using average monthly close price.
