## How to Calculate Inflation Rate for \$1, 1977 to 1978

Our calculations use the following inflation rate formula to calculate the change in value between 1977 and 1978:

CPI in 1978 CPI in 1977
×
1977 AUD value
=
1978 AUD value

Then plug in historical CPI values. The Australian CPI was 20.3 in the year 1977 and 21.9 in 1978:

21.920.3
×
\$1
=
\$1.08

\$1 in 1977 has the same "purchasing power" or "buying power" as \$1.08 in 1978.

To get the total inflation rate for the 1 years between 1977 and 1978, we use the following formula:

CPI in 1978 - CPI in 1977CPI in 1977
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

21.9 - 20.320.3
×
100
=
8%

Politics and news often influence economic performance. Here's what was happening at the time:

• Apple Computer incorperated by Steve Jobs, Steve Wozniak, and Ronald Wayne.
• The Hindu Kubh Mela gathered 15,000,000 people, making it (at the time) the biggest crowd gathering in history.
• First Apple II computers are shipped.
