The Rising Cost of Producing an Acre of Corn: A Historical Perspective (1975–2025)

Over the past 50 years, the cost of producing an acre of corn in the United States has risen dramatically, reflecting a complex mix of inflation, input costs, technological advances, land values, and market dynamics.

1970s–1980s: The Foundation Years

In 1975, the total cost to produce an acre of corn was around $250. During this period, farming was still heavily labor-intensive, and while fertilizer and energy costs were rising, they remained relatively modest. Throughout the late 1970s and early 1980s, production costs gradually increased, reaching about $310–320 per acre by the mid-1980s. Fertilizer, seed, and machinery costs all began climbing, while average yields hovered around 115 bushels per acre, keeping per-bushel costs around $2.70.

1990s: Steady but Manageable Growth

The 1990s brought moderate increases in costs. By 1999, the average cost per acre had reached $333, with yields increasing to about 135 bushels per acre, thanks to better hybrids and improved farming practices. Input costs, including land, seed, and chemicals, continued a steady upward trend, but the rate of increase was manageable, with per-bushel costs generally staying below $2.50.

2000s: Climbing Costs and Growing Yields

The early 2000s marked the beginning of steeper cost growth. By 2005, it cost nearly $416 to produce an acre of corn. This was driven in part by rising energy and fertilizer prices, alongside more expensive genetically modified seed. By the end of the decade, in 2009, the cost of production had ballooned to over $699 per acre, with yields rising to 158 bushels, and per-bushel costs exceeding $4.40 during the global commodity boom.

2010s: Cost Volatility and Tight Margins

The 2010s were marked by significant cost volatility. Input costs remained high, with production expenses ranging between $617 and $788 per acre. Yields increased to roughly 177–195 bushels per acre, but despite these improvements, margins remained tight. Farmers faced increasing pressure from fluctuating commodity prices, unpredictable weather, and tighter operating margins. Per-bushel costs averaged around $4.00 to $4.50, leaving little room for error.

2020s: Record Costs and a New Era of Risk

The 2020s have so far been the most expensive period in the history of corn production. By 2022, the cost per acre surged to over $791, driven by soaring fertilizer prices, labor shortages, fuel inflation, and supply chain disruptions. In 2023, production costs reached a record $974 per acre, with per-bushel costs peaking at $4.88. Even with high yields (around 200+ bushels per acre), the cost of doing business in agriculture reached unprecedented levels.

In 2024 and 2025, there's been a modest decline in total costs (to around $887 per acre), likely due to easing input prices and improved market stability. Still, per-bushel production costs remain high, hovering around $4.29, suggesting that risk management and cost efficiency are more important than ever for profitability.

Key Takeaways:

• Production costs per acre have grown more than 3.5x since 1975, from $250 to nearly $900 in 2025.

• Input costs, especially fertilizer, seed, and machinery, have been the largest drivers of cost increases.

• Yields have improved significantly, from around 125 bushels per acre in the 1970s to over 200 today, helping to mitigate some of the rising costs.

• Per-bushel costs have grown from $2.00 in 1975 to over $4.00 today — doubling over five decades.

This long-term trend underscores the importance of scale, efficiency, and innovation in modern farming. As farmland brokers and agricultural professionals, we must consider not just the price of land, but the growing cost and complexity of operating on it. Whether you’re buying, selling, or leasing farmland, understanding these long-term economic forces is critical to making smart, sustainable decisions.
