The Quiet Math of a Profitable Planting Season: Five Numbers Every Operator Should Be Watching Right Now
When I was reviewing operating lines at the bank, the farmers who made it through rough cycles all shared something. They knew five numbers like the back of their hand.
We’re in one of those cycles right now. Commodity prices have softened. Input costs remain stubbornly high. And working capital across the farm sector keeps falling. If you’re getting by on optimism and hoping corn breaks $5 before August, that’s a plan, just not a particularly good one.
I keep coming back to five numbers. You can look them up, write them down, and use them to make a decision before the week is out.
1. Your All-In Input Cost Per Acre
Start here because everything else gets calculated against it.
Fertilizer, seed, chemicals, fuel, land, custom hire, crop insurance premium: what does it cost you to farm one acre this season? University budgets for 2026 peg corn production costs between $675 and $747 per acre depending on tillage system, with soybean break-even prices running around $10.90 per bushel on a 50-bushel yield goal. Those are starting points, not your number. Your number comes from your own operation.
I talk to producers every week who don’t know their cost per acre within $50. That’s a problem when your margin for error has shrunk this thin. If you haven’t built a field-by-field cost sheet for 2026, that’s the first job, not planning for next year.
2. Basis, and Whether You’ve Priced Anything Against It
Basis is the difference between your local cash price and the Chicago Board of Trade (CBOT) futures price. Most operators know this. Fewer are watching it closely enough right now.
CBOT corn futures have been trading in the $4.50 to $4.70 range this May. Soybeans have seen more volatility, partly tied to ongoing uncertainty around Chinese purchases. Basis levels vary by elevator and region, but the question that matters is whether you have any new crop priced yet.
When I sat across from farmers at the loan desk, the ones who got burned had one thing in common: nothing priced and no plan. If your break-even is $4.70 and the market gives you a window at $4.90, that’s the call. You don’t need the perfect price. You need a price.
3. Your Crop Insurance APH, and Whether It Reflects Your Real Yield Potential
APH stands for Actual Production History. It’s the yield number your crop insurance guarantee is built from. The spring projected price for corn is $4.62 per bushel, down slightly from 2025, and $11.09 for soybeans.
Here’s the issue: your APH might be underselling your operation. If you’ve added high-productivity rented ground recently, those acres aren’t yet embedded in your history. If your APH reflects a drought year from earlier in the window, your yield baseline is lower than your production potential, and your insurance guarantee is lower than it should be.
Pull your APH records before the season closes out. Know what that floor is, know where it comes from, and ask your agent whether there’s a corrective option. The spring price is what it is. Your APH is something you can work on.
4. Working Capital Ratio
Working capital is your cushion. It tells you how much runway you have before a bad year becomes a borrowing crisis — and right now, a lot of operations have less of it than they think.
Working capital is your current assets (cash, grain inventory, receivables) minus your current liabilities: operating line, accounts payable, anything due in the next twelve months. The ratio version divides current assets by current liabilities. You want that number above 1.0. Below it, you owe more short-term than you have liquid, and your lender is paying close attention.
Lenders are increasingly evaluating farms on collateral rather than income, according to the FDIC’s 2026 Risk Review. Your land is carrying more credit weight than it used to. If you’re rolling operating debt into term debt to get through this cycle, have that conversation with your lender now. I watched producers with stretched balance sheets work through it by coming in early and being straight about where they stood. The ones who lost their options were the ones who waited until they had none left.
5. Interest Expense Per Acre
This one has improved from the 2024 peak, but not enough to stop tracking it.
USDA FSA published May 2026 lending rates, and operating loan rates have come down marginally from the highs. They’re still elevated by any reasonable historical standard. Even a modest rate difference of a point or more runs well into the thousands on a mid-size operation, and every dollar of that shows up in your break-even math.
Know your rate. Know your operating line balance. Calculate what you’re paying per acre to carry the crop from input to harvest. If that number surprises you, go back to metric one and recalculate your all-in cost with it included.
What I’d Do Right Now
None of these numbers require a consultant or a spreadsheet model. They require two hours with your records and an honest look at where things stand.
Know your cost per acre. Put a plan together for how you want to have your new crop priced. Verify your APH is accurate before next season’s enrollment window closes. Calculate your working capital ratio before your banker does. And build interest expense into every field budget.
I started Farm4Profit because I believed the gap between what farmers know and what they need to know is closable. These five numbers are a start. The season is underway. Run the math before it runs you.
