Inflation in 1970 and Its Effect on Dollar Value

Purchasing power decreased by 5.72% in 1970 compared to the previous year, 1969. On average, you would have to spend 5.72% more money in 1970 than in 1969 for the same item.

In other words, $100 in 1969 is equivalent in purchasing power to $105.72 in 1970.

The 1969 inflation rate was 5.46%. The inflation rate in 1970 was 5.72%. The 1970 inflation rate is higher compared to the average inflation rate of 3.98% per year between 1970 and 2018.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1970 was 38.8. It was 36.7 in the previous year, 1969. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.

Inflation by City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 1969 to 1970 (figures shown are purchasing power equivalents of $100):

New York experienced the highest rate of inflation during the 1 years between 1969 and 1970 (7.42%).

Seattle, Washington experienced the lowest rate of inflation during the 1 years between 1969 and 1970 (4.51%).


Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £100.00 in 1969 would be equivalent to £106.40 in 1970, an absolute change of £6.40 and a cumulative change of 6.40%.

In Canada, CA$100.00 in 1969 would be equivalent to CA$101.00 in 1970, an absolute change of CA$1.00 and a cumulative change of 1.00%.

Compare these numbers to the US's overall absolute change of $5.72 and total percent change of 5.72%.


Inflation by Spending Category

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 1969 and 1970.

Compare these values to the overall average of 5.72% per year:

Category Avg Inflation (%) Total Inflation (%) $100 in 1969 → 1970
Food 5.64 5.64 105.64
Shelter 9.09 9.09 109.09
Energy 2.65 2.65 102.65
Apparel 4.13 4.13 104.13
New vehicles 0.00 0.00 100.00
Used cars and trucks 0.00 0.00 100.00
Transportation services 0.00 0.00 100.00
Medical care services 7.11 7.11 107.11
Medical care commodities 2.31 2.31 102.31

It's important to note that not all categories may be tracked since 1969. This table and visualization use the earliest available data for each category.



How to Calculate Inflation Rate for $100, 1969 to 1970

This inflation calculator uses the following inflation rate formula:

CPI in 1970CPI in 1969
×
1969 USD value
=
1970 USD value

Then plug in historical CPI values. The U.S. CPI was 36.7 in the year 1969 and 38.8 in 1970:

38.836.7
×
$100
=
$105.72

$100 in 1969 has the same "purchasing power" or "buying power" as $105.72 in 1970.

To get the total inflation rate for the 1 years between 1969 and 1970, we use the following formula:

CPI in 1970 - CPI in 1969CPI in 1969
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

38.8 - 36.736.7
×
100
=
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 6.25% per year between 1969 and 1970 (vs all-CPI inflation of 5.72%), for an inflation total of 6.25%.

When using the core inflation measurement, $100 in 1969 is equivalent in buying power to $106.25 in 1970, a difference of $6.25. Recall that for All Items, the converted amount is $105.72 with a difference of $5.72.

In 1969, core inflation was 5.76%.


Comparison to S&P 500 Index

To help put this inflation into perspective, if you had invested $100 in the S&P 500 index in 1969, your investment would be worth approximately $98.35 in 1970. This is a change of -1.65%.

This means the nominal return on a $100 investment is $-1.65, but inflation would eat into your real returns.

Inflation would account for 5.41% of your returns ($-0.09), for an inflation-adjusted real return of about $-1.57.


News headlines from 1969
