$1 in 1979 is equivalent in purchasing power to about $1.13 in 1980. The dollar had an average inflation rate of 13.50% per year between 1979 and 1980, producing a cumulative price increase of 13.50%. Purchasing power decreased by 13.50% in 1980 compared to 1979. On average, you would have to spend 13.50% more money in 1980 than in 1979 for the same item.

This means that prices in 1980 are 1.13 times higher than average prices since 1979, according to the Bureau of Labor Statistics consumer price index.

The 1979 inflation rate was 11.35%. The inflation rate in 1980 was 13.50%. The 1980 inflation rate is higher compared to the average inflation rate of 2.97% per year between 1980 and 2021.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1980 was 82.40. It was 72.60 in the previous year, 1979. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 1979 to 1980 (figures shown are purchasing power equivalents of $1):

**Dallas-Fort Worth, Texas**: 16.95% average rate, $1 → $1.17, cumulative change of 16.95%**Seattle, Washington**: 16.77% average rate, $1 → $1.17, cumulative change of 16.77%**Detroit, Michigan**: 15.90% average rate, $1 → $1.16, cumulative change of 15.90%**San Francisco, California**: 15.42% average rate, $1 → $1.15, cumulative change of 15.42%**Chicago, Illinois**: 14.42% average rate, $1 → $1.14, cumulative change of 14.42%**Miami-Fort Lauderdale, Florida**: 14.04% average rate, $1 → $1.14, cumulative change of 14.04%**Atlanta, Georgia**: 13.85% average rate, $1 → $1.14, cumulative change of 13.85%**Philadelphia, Pennsylvania**: 13.05% average rate, $1 → $1.13, cumulative change of 13.05%**Houston, Texas**: 12.75% average rate, $1 → $1.13, cumulative change of 12.75%**Boston, Massachusetts**: 12.69% average rate, $1 → $1.13, cumulative change of 12.69%**New York**: 11.29% average rate, $1 → $1.11, cumulative change of 11.29%

Dallas-Fort Worth, Texas experienced the highest rate of inflation during the 1 years between 1979 and 1980 (16.95%).

New York experienced the lowest rate of inflation during the 1 years between 1979 and 1980 (11.29%).

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

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1979 would be equivalent to £1.18 in 1980, an absolute change of £0.18 and a cumulative change of 17.99%.

In Canada, CA$1.00 in 1979 would be equivalent to CA$1.11 in 1980, an absolute change of CA$0.11 and a cumulative change of 11.06%.

Compare these numbers to the US's overall absolute change of $0.13 and total percent change of 13.50%.

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 1979 and 1980.

Compare these values to the overall average of 13.50% per year:

Category | Avg Inflation (%) | Total Inflation (%) | $1 in 1979 → 1980 |
---|---|---|---|

Food and beverages | 8.53 | 8.53 | 1.09 |

Housing | 15.69 | 15.69 | 1.16 |

Apparel | 7.07 | 7.07 | 1.07 |

Transportation | 17.81 | 17.81 | 1.18 |

Medical care | 10.95 | 10.95 | 1.11 |

Recreation | 0.00 | 0.00 | 1.00 |

Education and communication | 0.00 | 0.00 | 1.00 |

Other goods and services | 9.10 | 9.10 | 1.09 |

For all these visualizations, it's important to note that not all categories may have been tracked since 1979. This table and charts use the earliest available data for each category.

Our calculations use the following inflation rate formula to calculate the change in value between 1979 and 1980:

Then plug in historical CPI values. The U.S. CPI was 72.6 in the year 1979 and 82.4 in 1980:

$1 in 1979 has the same "purchasing power" or "buying power" as $1.13 in 1980.

To get the total inflation rate for the 1 years between 1979 and 1980, we use the following formula:

CPI in 1980 - CPI in 1979CPI in 1979

Plugging in the values to this equation, we get:

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 12.42% per year between 1979 and 1980 (vs all-CPI inflation of 13.50%), for an inflation total of 12.42%.

When using the core inflation measurement, $1 in 1979 is equivalent in buying power to $1.12 in 1980, a difference of $0.12. Recall that for All Items, the converted amount is $1.13 with a difference of $0.13.

In 1979, core inflation was 9.74%.

To help put this inflation into perspective, if we had invested $1 in the S&P 500 index in 1979, our investment would be * nominally* worth approximately $1.48 in 1980. This is a return on investment of 47.59%, with an absolute return of $0.48 on top of the original $1.

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 11.89% of returns ($0.18) during this period. This means the inflation-adjusted * real* return of our $1 investment is $0.30. You may also want to account for capital gains tax, which would take your real return down to around $0 for most people.

Original Amount | Final Amount | Change | |
---|---|---|---|

Nominal |
$1 | $1.48 | 47.59% |

RealInflation Adjusted |
$1 | $1.30 | 30.04% |

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 1979 to latest available data for 1980 using average monthly close price.

For more details on the S&P 500 between 1979 and 1980, see the stock market returns calculator.

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

- Ayatollah Khomeini returns to Iran after fifteen years of exile.
- Ugandan dictator Idi Amin flees to Libya after the Tanzanian army captures Kampala, Uganda's capital.
- Margaret Thatcher becomes Prime Minister of United Kingdom, the first ever woman to hold the position.
- Afghanistan is invaded by the Soviets and overthrowing of President Hafizullah Amin.

Raw data for these calculations comes from the Bureau of Labor Statistics' Consumer Price Index (CPI), established in 1913. Inflation data from 1665 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University.
