Propane costs rarely arrive evenly across the year. Grain drying can spike fall expenses, livestock heat can peak in winter, and irrigation or standby power can raise summer demand. A useful propane budget turns seasonal work into gallons, delivery dates, and cash needs. It estimates each activity, prices several scenarios, and allows for weather and production changes. It also shows which gallons are contracted and which remain exposed to market prices. Propane can power grain dryers, irrigation engines, building heat, water heaters, generators, and flame weeders. Because these uses peak at different times, an annual total cannot guide purchasing or deliveries.
Review three years of delivery tickets, tank readings, dryer logs, and equipment hours when available. Match gallons with acres, bushels, crop moisture, weather, and animal numbers so unusual seasons do not distort the forecast.
Adjust past use for added acres, new barns, larger dryers, irrigation changes, or a standby generator. New equipment may lower demand, so use current machine data instead of applying an old fuel rate.
Divide demand by season. Grain drying often creates a concentrated harvest load, while livestock and greenhouse heating create a longer winter draw. This shows when storage, deliveries, and cash matter most.
Build mild, normal, and severe weather cases. Cold raises building-heating demand, while wet or cool harvest conditions can increase the moisture removed from grain. The severe case reveals the fuel and cash buffer needed during difficult conditions.
For heaters, irrigation engines, and generators, multiply expected hours by measured or rated fuel use. Compare the result with delivery history; a large mismatch may reveal weak records, maintenance problems, or shared loads.
Add a reserve after estimating each use. Farms with distant suppliers, weather-sensitive livestock, or heavy harvest demand need more room. The reserve must stay within approved storage limits.
Gas-fired grain dryers may use 0.015 to 0.025 gallons per bushel for each moisture point removed. Iowa State has used 0.018 gallon as an average estimate, although dryer design and weather change actual use.
Drying 100,000 bushels of corn by eight moisture points at 0.018 gallon per bushel-point requires about 14,400 gallons. At $2 per gallon, fuel costs $28,800; at $2.50, it costs $36,000. That $7,200 difference shows why farms should test several prices. A budget based on one optimistic quote may leave too little operating cash if prices rise before harvest.
Estimate livestock, greenhouse, shop, and water-heating demand from recent gallons. Adjust for insulation, animal numbers, thermostat settings, and expected cold. Weekly readings can separate base use from cold-weather spikes.
Use a local delivered quote, then test lower and higher prices. In March 2026, EIA residential averages were about $2.19 per gallon in the Midwest and $3.57 on the East Coast; farm prices can differ. Regional averages are useful for context, not final budgeting. Supplier contracts, delivery distance, volume, taxes, and tank ownership can all change the farm’s delivered price.
Suppliers may offer early fills, fixed prices, caps, prebuy plans, or market pricing. A prebuy improves certainty but can require early cash, while market pricing leaves more exposure. The right choice depends on cash flow and risk tolerance. A farm may contract its expected base demand while leaving a smaller share open for changing weather or production.
Include electricity for dryer fans, tank rental, delivery fees, inspections, burner service, and interest on operating funds. For grain, compare on-farm drying with elevator charges, shrink, hauling, storage plans, and harvest delays. The lowest propane price does not always create the lowest production cost. A cheaper supplier with slow deliveries may cause dryer downtime when the farm needs fuel most.
List each tank by location, ownership, connected equipment, and usable capacity. Tank level, cold weather, and simultaneous demand affect performance, so nameplate size alone is not enough. A farm may have enough annual storage but still lack capacity during a busy week. Compare tank capacity with the highest expected daily use and the supplier’s delivery lead time.
An early fill places fuel on the farm before harvest or winter demand rises. Propane does not face gasoline-style aging, and PERC notes that early-fill programs may improve cost certainty and readiness. An early fill still ties up cash. Compare the price benefit with financing costs and the value of having fuel available before the first major seasonal load.
Give the supplier expected gallons and timing before the season starts. Discuss weekends, remote tanks, poor roads, and overlapping equipment loads. Agree on monitoring and reordering. A scheduled delivery plan can reduce emergency calls. It also gives the supplier time to prepare for a farm that may use thousands of gallons during a short harvest period.
Delivery trucks need safe access during rain, snow, mud, and harvest traffic. Clear vegetation, protect tanks from vehicles, mark hazards, and repair weak lanes or pads. Poor access can create a farm-level shortage even when the supplier has plenty of propane. Include road, gate, or tank-pad repairs in the seasonal budget when access has caused past delays.
Review tank ownership, contract volume, minimum deliveries, emergency service, and restrictions. Another company may not be allowed to fill a leased tank, so confirm backup options early. Ask what happens when actual use exceeds contracted gallons. The answer may affect pricing, delivery priority, or whether the farm must buy added fuel at the current market rate.
Budget for service before high-use periods. Burners, regulators, dryers, piping, valves, heaters, and controls must work correctly. PERC publishes farm safety guidance for crop dryers and confinement barns. Maintenance also supports accurate budgeting. A poorly adjusted burner or damaged component can waste fuel and make actual consumption exceed the planned number.
A seasonal propane budget must show when payment occurs. A summer prebuy may require cash before grain sales, while market-priced deliveries can create large harvest bills. Match payments with the operating line, livestock receipts, crop sales, and cash. Separate contracted gallons from unpriced gallons to show remaining market risk. Record delivery charges, tank rent, and finance costs separately so the true seasonal expense stays visible. Update the cash forecast during high-use months. Changes in harvested bushels, incoming grain moisture, cold weather, irrigation hours, or tank levels can move the budget quickly. When actual use exceeds the high-case forecast, revise delivery timing and working-capital needs immediately.
First, reduce waste. Maintain dryers and burners, seal heated buildings, repair controls, and avoid heating empty areas. Track propane per bushel, animal space, irrigation hour, or greenhouse square foot. Second, spread purchasing decisions across time. Early fills and contract options can reduce dependence on one price date. EIA’s 2025–2026 data also show that propane prices moved during the heating season, which supports testing more than one price in the budget. Third, compare propane cost with the value it protects. Timely drying can reduce spoilage and delays, while dependable heat protects animals and water systems. The cheapest plan fails when it creates operating risk.
Create one worksheet connecting farm activities, gallons, dates, prices, tank capacity, deliveries, and cash payments. Use farm records first, extension benchmarks second, and broad averages last. Review the plan with the manager, lender, supplier, and service provider. Confirm contract volumes, tank ownership, access, monitoring, service dates, emergency contacts, and unpriced demand. A strong propane budget does not predict every cold front or wet harvest. It gives the farm enough fuel, storage, cash, and decision room to respond when conditions change. After the season, compare forecast gallons, delivered gallons, average price, and cost per production unit so the next budget starts with better numbers.
