Fast Food Inflation: How Burger Prices Have Changed Since 2020
Published April 6, 2026 · BLS + industry data
The Big Mac has risen 22.6% since 2020. Homemade burger ingredients are up 50.2%. And the median restaurant burger now costs $14.64 —4.4x what it costs to cook at home. Here is the full timeline.
The Big Mac Timeline: 2017-2026
McDonald's flagship burger has steadily climbed from $4.19 in 2017 to $5.91 in 2026. The sharpest increases came during 2022-2024, when fast food chains raised prices faster than overall inflation.

Why Fast Food Prices Rose Faster Than Groceries
Several structural forces pushed fast food prices higher, faster than the ingredients they use:
- Labor cost surge: California's $20/hour fast food minimum wage (AB 1228, effective April 2024) set a new floor nationally. Other states followed. Labor is ~28% of a fast food burger's price.
- Commercial rent inflation: Retail rents in prime fast food locations have outpaced residential rent growth, adding 2-3% per year to operating costs.
- Margin expansion: Major chains used inflation cover to widen profit margins. McDonald's operating margin hit 46% in 2024, up from 41% in 2019.
- Shrinkflation: Some chains reduced portion sizes while maintaining or raising prices, effectively increasing the per-ounce cost even more than headline numbers suggest.
The Widening Gap
In 2020, a Big Mac cost 2.2x a homemade burger. In 2026, it costs 1.8x. The gap is widening because restaurant costs (labor, rent, corporate overhead) are inflating faster than grocery commodity prices.
BLS data confirms the divergence: food away from home inflation is running at +3.9% year-over-year, while food at home is at +2.4%. That 1.5-point annual gap compounds over time.
The Cheeseburger Index as an Inflation Gauge
The Cheeseburger Index is up +15.0% year-over-year — significantly higher than both the overall CPI (+2.8%) and the food-at-home CPI (+2.4%). Ground beef, which accounts for ~60% of our index, is the primary driver. The U.S. cattle herd hit multi-decade lows in 2024-2025, pushing beef prices higher.
What Comes Next
The USDA projects food-at-home inflation of 3.1% and food-away-from-home inflation of 3.9% for 2026. If those forecasts hold, the gap between homemade and fast food burger prices will continue to widen. For budget-conscious families, the math increasingly favors cooking at home.
Frequently Asked Questions
How much has fast food inflation been since 2020?
The average Big Mac has risen from $4.82 in 2020 to $5.91 in 2026 — a 22.6% increase. Homemade burger ingredients have risen from $2.19 to $3.29 (50.2%) over the same period.
Is fast food getting more expensive faster than grocery prices?
Yes. BLS data shows food away from home (restaurants and fast food) inflation at +3.9% year-over-year, while food at home (groceries) is rising at +2.4%. Restaurant prices are rising about 1.6x faster than grocery prices.
Why has the Big Mac gotten so expensive?
Multiple factors drive fast food inflation: minimum wage increases in key states (California's $20/hr fast food minimum), rising commercial rents, supply chain cost increases, and corporate margin expansion. McDonald's ingredients cost roughly 30% of menu price — the remaining 70% (labor, rent, profit) is where inflation hits hardest.
What is the most inflation-resistant way to eat burgers?
Cooking at home remains the most inflation-resistant option. Even though grocery prices have risen, the homemade burger has increased 50.2% since 2020 versus 22.6% for a Big Mac. The gap between fast food and homemade prices continues to widen.
