Bulk Fuel Storage & Consumption Planner

Size your on-farm tanks based on peak seasonal consumption with reorder points

Enter your equipment fleet with daily hours and fuel consumption rates to calculate peak seasonal demand by fuel type (diesel, gasoline, DEF). Get recommended tank sizes, reorder points based on delivery lead times, and annual fuel cost projections for budget planning.

Pro Tip: Size your tank for peak week, not average annual consumption. Harvest might burn 3x your normal daily rate. Running out of fuel during harvest costs far more than a slightly oversized tank.

How It Works

  1. Build Your Fleet

    Add each piece of equipment with fuel type, gallons per hour consumption rate, daily operating hours during peak season, and active days per week.

  2. Set Delivery Parameters

    Enter your fuel delivery lead time (days), desired reserve days, and minimum delivery quantity. The calculator uses these for reorder point and tank sizing.

  3. Review Storage Plan

    See peak daily consumption by fuel type, recommended tank sizes, reorder points, and total season cost. DEF requirements are calculated automatically at 2.5% of diesel consumption.

Built For

  • Farmers sizing new bulk fuel tanks
  • Farm managers budgeting annual fuel costs
  • Operations planning fuel delivery logistics
  • Equipment dealers recommending fuel infrastructure

Assumptions

  • Fuel consumption rates are user-entered per piece of equipment and represent loaded operating conditions
  • DEF consumption is estimated at 2.5% of diesel consumption for Tier 4 Final engines
  • Peak daily consumption assumes all listed equipment operates simultaneously at the entered hours per day
  • Delivery lead time is constant and does not account for seasonal demand spikes at fuel suppliers
  • Tank sizing includes a reserve buffer based on user-entered safety days beyond delivery lead time
  • Fuel prices are constant over the planning period and do not account for seasonal price fluctuations

Limitations

  • Actual fuel consumption varies 15-30% from estimates based on load conditions, terrain, and operator behavior
  • Does not account for fuel degradation in storage — diesel can develop microbial growth and oxidation after 6-12 months
  • Tank sizing does not include fire code setback requirements, secondary containment, or spill prevention control and countermeasure (SPCC) plan requirements
  • Does not calculate fuel delivery economics (bulk pricing tiers, minimum delivery charges, split-load surcharges)
  • DEF storage requirements for heated or indoor storage in cold climates are not modeled (DEF freezes at 12 degrees F)
  • Does not address fuel filtration, vent sizing, or dispensing pump specifications for the recommended tank

Frequently Asked Questions

Size based on peak daily consumption × (delivery lead time + safety reserve days). If your fleet burns 200 gal/day peak and delivery takes 3 days with 2 days reserve, you need at least 1,000 gallons. Round up to the next standard tank size. This calculator does this math automatically based on your fleet data.
Add up every piece of equipment running during your busiest period - harvest typically drives the peak. A combine at 25 gal/hr plus two grain carts at 8 gal/hr plus trucks adds up fast. Enter your actual equipment to get an accurate peak daily number.
If running Tier 4 diesel equipment, yes. DEF consumption is roughly 2-3% of diesel consumption. The calculator estimates DEF needs at 2.5% of diesel automatically. DEF freezes at 12°F, so plan heated or indoor storage in cold climates.
Disclaimer: Fuel consumption estimates depend on equipment condition, load factors, and operating conditions. Actual consumption varies. Verify fuel storage requirements with your fuel supplier and local fire codes.
