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 £139,765.00 in 2017 would be equivalent to £143,538.66 in 2018, an absolute change of £3,773.65 and a cumulative change of 2.70%.

In Canada, CA$139,765.00 in 2017 would be equivalent to CA$142,935.19 in 2018, an absolute change of CA$3,170.19 and a cumulative change of 2.27%.

Compare these numbers to the US's overall absolute change of $3,483.86 and total percent change of 2.49%.

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 2017 and 2018:

• Gas prices increased from $2.35 per gallon to $2.54
• Bread prices increased from $1.35 per loaf to $1.28
• Egg prices increased from $1.60 per carton to $1.77
• Chicken prices increased from $1.42 per per 1 lb of whole chicken to $1.51
• Electricity prices increased from $0.13 per KwH to $0.14

This chart shows the average rate of inflation for select CPI categories between 2017 and 2018.

Compare these values to the overall average of 2.49% per year:

For all these visualizations, it's important to note that not all categories may have been tracked since 2017. This table and charts use the earliest available data for each category.

How to calculate inflation rate for $139,765, 2017 to 2018

Our calculations use the following inflation rate formula to calculate the change in value between 2017 and 2018:

Then plug in historical CPI values. The U.S. CPI was 245.12 in the year 2017 and 251.23 in 2018:

$139,765 in 2017 has the same "purchasing power" or "buying power" as $143,248.86 in 2018.

To get the total inflation rate for the 1 years between 2017 and 2018, 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 2.05% per year on average between 2017 and 2018. The total PCE inflation between these dates was 2.05%. In 2017, PCE inflation was 1.75%.

This means that the PCE Index equates $139,765 in 2017 with $142,625.75 in 2018, a difference of $2,860.75. Compare this to the standard CPI measurement, which equates $139,765 with $143,248.86. The PCE measured -0.45% 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 2.14% per year between 2017 and 2018 (vs all-CPI inflation of 2.49%), for an inflation total of 2.14%. In 2017, core inflation was 1.84%.

When using the core inflation measurement, $139,765 in 2017 is equivalent in buying power to $142,755.61 in 2018, a difference of $2,990.61. Recall that the converted amount is $143,248.86 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 2.02% per year between 2017 and 2018, a total inflation amount of 2.02%.

According to the Chained CPI measurement, $139,765 in 2017 is equal in buying power to $142,585.89 in 2018, a difference of $2,820.89 (versus a converted amount of $143,248.86/change of $3,483.86 for All Items).

In 2017, chained inflation was 1.76%.

Comparison to S&P 500 Index

To help put this inflation into perspective, if we had invested $139,765 in the S&P 500 index in 2017, our investment would be nominally worth approximately $166,360.35 in 2018. This is a return on investment of 19.03%, with an absolute return of $26,595.35 on top of the original $139,765.

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 2.43% of returns ($4,045.94) during this period. This means the inflation-adjusted real return of our $139,765 investment is $22,549.41. You may also want to account for capital gains tax, which would take your real return down to around $19,167 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 2017 to latest available data for 2018 using average monthly close price.
