Gasoline prices are one of the most visible costs households face, while median household income reflects how much the typical family earns. Comparing gas prices to median income shows whether fuel became more or less affordable over time, not just whether prices went up in dollar terms. Looking back to 1970 captures the shift from postwar wage growth to the modern era of slower real income gains and higher cost pressures.
Gasoline affordability relative to median income
The table below shows US average gasoline prices, median household income, and how many gallons of gasoline a median-income household could theoretically buy with one year of income.
| Year | Median household income ($) | Gasoline price ($ per gallon) | Gallons per year of income |
|---|---|---|---|
| 1970 | 9,870 | 0.36 | 27,400 |
| 1980 | 21,020 | 1.25 | 16,800 |
| 1990 | 29,940 | 1.16 | 25,800 |
| 2000 | 41,990 | 1.51 | 27,800 |
| 2005 | 46,330 | 2.36 | 19,600 |
| 2010 | 49,280 | 2.83 | 17,400 |
| 2015 | 56,520 | 2.44 | 23,200 |
| 2020 | 67,520 | 2.18 | 31,000 |
| 2022 | 74,580 | 3.63 | 20,500 |
| 2025 | ~82,000 | ~3.00 | ~27,300 |

How affordability changed over time
1970s
In 1970, gasoline was extremely affordable relative to income. A median household could buy over 27,000 gallons with one year of earnings. The oil shocks of the decade sharply reduced affordability, cutting gasoline purchasing power by nearly 40 percent by 1980.
1980s
Despite high nominal gas prices early in the decade, income growth helped restore affordability. By 1990, gasoline purchasing power nearly returned to 1970 levels, even though prices at the pump were much higher in dollar terms.
1990s
The 1990s were a strong period for gasoline affordability. Income growth outpaced fuel prices, allowing households to buy more gasoline per dollar earned. Driving became cheaper relative to income even as vehicle ownership expanded.
2000s
Rising oil prices reversed this trend. By 2005, the number of gallons a household could buy with annual income dropped sharply. Gasoline absorbed a larger share of household budgets, particularly for commuters and rural households.
2010s
Income growth resumed while gas prices fluctuated. The collapse in oil prices after 2014 significantly improved affordability. By 2020, gasoline purchasing power reached its highest level in the modern era.
2020s
Inflation pushed both incomes and gas prices higher, but not evenly. In 2022, gasoline affordability fell sharply as fuel prices spiked faster than wages. By 2025, affordability improved again, though it remains sensitive to price volatility.
