Calculator guide

Understanding Corn Production Scenario Comparison Calculator

Comparing two corn scenarios only works when production, revenue, variable cost, fixed-cost allocation, and break-even price stay paired by scenario.

Calculate production Acres multiplied by market yield gives saleable bushels for each scenario.
Calculate revenue Scenario B has more bushels but a lower entered price.
Calculate variable costs The variable-cost rate is applied to planted acres.
Subtract variable and fixed costs Both scenarios absorb the same fixed-cost allocation.

Calculation method

How the calculation works

Calculate production, revenue, variable cost, shared fixed-cost allocation, contribution, and break-even price independently for two corn scenarios. Calculate each scenario independently, subtract variable and shared fixed cost from revenue, then subtract Scenario A contribution from Scenario B contribution.

Detailed calculation process

Compare corn scenario contribution and break-even prices

The default compares 500 acres at 185 bu/acre and $4.70/bu with 500 acres at 200 bu/acre and $4.45/bu, using $690/acre versus $740/acre variable cost and $120,000 shared fixed cost.

General formula: Q_A = a_A y_AQ_B = a_B y_BR_A = Q_A p_AR_B = Q_B p_BV_A = a_A c_AV_B = a_B c_BK_A = R_A-V_A-FK_B = R_B-V_B-FD = K_B-K_ABE_A = (V_A+F)/Q_ABE_B = (V_B+F)/Q_B Each scenario first turns acres and yield into bushels, then bushels and price into revenue. Variable cost is acre-based. The same fixed-cost allocation is subtracted from each scenario before comparing the contribution difference.

What each symbol means

a_A, a_B Scenario planted acres (acres).
y_A, y_B Market yield (bushels/acre).
p_A, p_B Market price ($/bushel).
c_A, c_B Variable cost ($/acre).
F Shared fixed cost allocated to either scenario ($).
K_A, K_B, D, BE Contribution after fixed cost, contribution difference, and break-even price ($, $/bushel).

Worked substitution with the default inputs

1. Calculate production Q_A = 500 x 185 = 92,500 buQ_B = 500 x 200 = 100,000 bu Acres multiplied by market yield gives saleable bushels for each scenario.
2. Calculate revenue R_A = 92,500 x 4.70 = $434,750R_B = 100,000 x 4.45 = $445,000 Scenario B has more bushels but a lower entered price.
3. Calculate variable costs V_A = 500 x 690 = $345,000V_B = 500 x 740 = $370,000 The variable-cost rate is applied to planted acres.
4. Subtract variable and fixed costs K_A = 434,750 - 345,000 - 120,000 = -$30,250K_B = 445,000 - 370,000 - 120,000 = -$45,000 Both scenarios absorb the same fixed-cost allocation.
5. Reconcile difference and break-even prices D = -45,000 - (-30,250) = -$14,750BE_A = 465,000/92,500 = $5.027/buBE_B = 490,000/100,000 = $4.900/bu The default says Scenario B contributes $14,750 less, while its larger production lowers its break-even price.

The default Scenario B contribution is $14,750 below Scenario A, with break-even prices of $5.027/bu for A and $4.900/bu for B.

Worked situations

Practical examples

  • The default compares 500 acres at 185 bu/acre and $4.70/bu with 500 acres at 200 bu/acre and $4.45/bu, using $690/acre versus $740/acre variable cost and $120,000 shared fixed cost.
  • The default Scenario B contribution is $14,750 below Scenario A, with break-even prices of $5.027/bu for A and $4.900/bu for B.

Better inputs

Useful tips

  • Keep acres, yield, price, and variable cost paired within Scenario A or Scenario B instead of mixing assumptions across columns.
  • Use the same fixed-cost allocation basis for both scenarios so the contribution difference reflects operating assumptions.
  • Enter yield in bushels per acre and price in dollars per bushel, then stress-test them separately because they can move in opposite directions.

Before relying on the result

Limitations and common mistakes

  • Moisture, basis, drying, storage, crop insurance, rent, hedging, financing, taxes, and quality discounts are excluded.
  • Shared fixed cost is allocated once to each scenario.
  • Break-even price assumes all modeled bushels are marketable.

Reference

Key terms

Contribution after fixed cost
Revenue less variable cost and the entered fixed-cost allocation.
Break-even price
Price per bushel needed to cover variable plus fixed cost.
Scenario delta
Scenario B contribution minus Scenario A contribution.

Important note

Calculated from the entered field and production values. Confirm seed-lot data, equipment calibration, labels, local conditions, and applicable agronomic guidance.

Frequently asked questions

Why can contribution be negative?

The entered revenue is not enough to cover variable cost plus shared fixed cost.

Why does B have a lower break-even price?

B spreads higher total cost over more bushels.

Is fixed cost split between A and B?

No. The same allocation is applied to each standalone scenario.

Does this include crop insurance?

Only if you include it in the entered costs.
