Farm Fuel Cost Calculator
What does fuel cost your farm? Estimate corn and soybean fuel costs per acre and for the whole farm. Compare tillage, hauling, irrigation, and propane drying with editable assumptions and dated regional fuel prices.

PLAN YOUR SEASON
Estimate corn and soybean fuel costs.
The Farm Fuel Calculator estimates fuel use and cost per acre and for the whole farm. Compare conventional, reduced tillage, and no-till starting programs, then adjust acreage, field operations, fertilizer application passes, hauling, irrigation, and grain drying to match your operation.
Enter your own supplier quotes or use the dated regional benchmarks. The historical comparison holds the farm plan fixed and changes only fuel prices, so it shows price impact rather than actual historical farm expenses.
Start with your acres. Refine the details.
Use Refine for a guided estimate or Details to edit fuel rates and individual operations. Print a report, export an editable Excel workbook, or save a scenario file to open later.
No account is required. Farm inputs stay in this browser page; saved scenario files stay on your computer. This is a fuel-only planning estimate. It excludes labor, repairs, ownership, fertilizer materials, electricity, commercial drying fees, and crop profitability.
THE MATH BEHIND THE ESTIMATE
Calculation methodology & assumptions
All fuel volumes use US gallons, areas use acres, and prices use nominal US dollars. Replace starting rates with measured fuel use when available; equipment, soil, depth, weather, and travel affect actual consumption.
- Fieldwork diesel per crop acre = sum of each activity’s gallons per acre per pass × passes × share of acres covered.
- Irrigation diesel per crop acre = seasonal gallons per irrigated acre × irrigated share. Enter your seasonal fuel rate; irrigation starts off.
- Hauling diesel per crop acre = yield × share hauled ÷ truck capacity × (2 × one-way miles ÷ round-trip MPG + idle hours per load × idle gallons per hour). Return travel is included; loads are continuous planning equivalents.
- Drying propane per crop acre = wet bushels per acre × share dried × moisture percentage points removed × propane gallons per bushel per point.
- Crop fuel cost per acre = (fieldwork + irrigation gallons) × farm diesel price + hauling gallons × road diesel price + drying gallons × propane price.
- Whole-farm fuel cost = sum of crop fuel cost per acre × crop acres. Divide by total crop acres for the acreage-weighted farm cost per acre.
Shares in these equations are fractions: 50% is 0.5. For example, an operation using 0.5 gallon per acre per pass over 1,000 acres, twice, at $4 per gallon costs $4,000. This is a calculation example, not a current price quote.
Price timing: Current prices applies one price per fuel across the season. By operation month prices each activity’s existing gallons using its allocated month in both comparison years. Edit operation months in Details; allocations must total 100%. Previous-year November tillage belongs to the following crop. Past gaps remain unavailable; future months in the selected season use the current quote and are labelled estimated. Current-month benchmarks are month to date. Saved seasonal scenarios retain their schedules and monthly prices.
Corn drying starts at 0.018 propane gallon per bushel per moisture point, using Iowa State drying guidance. Removing five points from 200 wet bushels per acre uses 18 gallons per acre at that rate. Actual dryer performance varies; soybean drying starts off and needs a suitable user-selected rate.

Chisel plowing and combining use project defaults. Grain-cart rates are derived from rounded farmdoc fuel-and-lubrication costs divided by $3.30; they are estimates rather than directly measured gallons. Tillage names identify editable starting programs, not formal conservation-practice classifications.

Farm fuel price history
Compare Illinois farm diesel, Midwest road diesel, Iowa propane, and Midwest regular gasoline. The tables below are available without JavaScript and use the same verified observations and monthly calculations as the interactive Price history chart. Gasoline is for history comparison only and does not enter farm cost estimates.
Snapshot checked . Coverage varies by fuel; the source table below gives the last observation date for each series. The snapshot month is month to date. A downloaded copy retains its bundled prices until you obtain a refreshed copy or enter a quote.

Monthly values are arithmetic means of available observations grouped by report week-ending or observation date. These calculated means are not EIA’s separately published monthly series. Missing observations remain unavailable (—); they are not interpolated or carried forward. Regional reports take precedence over dated national weekly references. † identifies a national weekly reference when no regional observation is available; it is not a regional monthly average.

Price sources & historical coverage
| Benchmark | Price basis | Observation dates | Source |
|---|---|---|---|
| Illinois farm diesel | Distributor asking prices, FOB. Not a delivered farm quote. | to , with gaps | USDA AMS source |
| Midwest road diesel | On-highway retail diesel, including taxes. | to , with gaps | EIA source |
| Iowa propane | Distributor asking prices, FOB. Iowa benchmark, not Illinois propane. | to , with gaps | USDA AMS source |
| Midwest regular gasoline | Regular, all formulations, retail including taxes. History comparison only. | to , with gaps | EIA source |
These regional benchmarks are not a delivered or contracted price for every farm. Illinois farm-diesel and Iowa propane reports supply October–December 2025 monthly values; retained national weekly references are not averaged into those months. Current-price comparisons apply the selected historical month’s price to the entire farm program. Operation-month comparisons use the editable activity schedule and approximate buying fuel when used; neither mode reconstructs actual farm purchases.
