YielixCrop Break Even Yield and Price Calculator
Find the harvest yield or selling price needed to cover your entered crop costs. Adjust costs, expected yield and the paid share of harvest to see expected profit, margin and distance from break-even. Example values are illustrative; enter your own budget and price.
Quick Threshold Planning and Cost Scope
Use one yield and price scenario to ask how much harvest must be produced, or what selling price would cover the entered costs. Compare conservative and optimistic scenarios separately. Detailed Crop Profit budgeting uses editable enterprise cost lines and scenario totals; this tool uses two area-cost totals and one output-unit cost. Greenhouse ROI evaluates greenhouse investment and returns over time; a one-season crop threshold does not establish investment payback.
Fixed area costs can include allocated land rent, equipment depreciation and insurance. Variable area costs can include seed, fertilizer, crop protection and field operations. Include hired and unpaid labor, financing, taxes and storage if the intended budget must recover them. Nothing is added automatically: omitted costs remain excluded. Put each expense in one category only. Costs entered per area stay constant as the chart varies yield; only the saleable-output cost scales with paid quantity.
Marketable Harvest and Other Income
Harvest yield is measured before the marketable fraction is applied. At 80% marketable, 5 t/ha harvest supplies 4 t/ha of paid output. With the example costs, the harvest threshold rises to 800 ÷ (0.8 × 190) = 5.263158 t/ha; the price threshold becomes 10 + 800 ÷ 4 = 210/t. Use Harvest Loss Calculator to inform a loss assumption, and Grain Moisture Shrink for drying mass changes. Reconcile moisture, handling and rejection losses with your yield basis so the same loss is not deducted twice.
Other income is off by default, contributing an explicit zero. Enable it only for a defensible per-area amount, such as a known crop payment or by-product receipt. Keep payment conditions and timing in mind; speculative income can make a threshold misleading. At 200/ha other income with the original example, the harvest threshold is 600 ÷ 190 = 3.157895 t/ha and the price threshold is 10 + 600 ÷ 5 = 130/t.
Build a Defensible Yield and Cost Scenario
Start with measured field history and use Yield Estimator to explore a harvest scenario, rather than treating the threshold as a yield forecast. Use Seed Rate Calculator to estimate seed quantity, then multiply by your own seed price before including it in variable area costs. Check the published seed-rate and crop-rotation guides below when reviewing establishment and rotation assumptions.
Inputs Explained
- Fixed and variable area costs
- Finite costs from zero upward per hectare or acre. Include the costs you want this crop to recover; there is no preset budget ceiling, but amounts and converted results must remain safely displayable.
- Saleable-output costs and output price
- Finite amounts from zero upward per metric tonne or pound in the same currency. Output costs apply only to marketable output. Excessively large prices or converted currency results are rejected with a field error.
- Predicted harvest yield
- Finite mass per area from zero upward before losses; no agronomic maximum is assumed. A tonne means 1000 kg; pounds avoid assuming a crop-specific bushel weight.
- Marketable fraction
- Paid share of harvested output, greater than 0% and at most 100%.
- Other per-area income
- Off by default and explicitly zero in the model. When enabled, enter a non-negative amount or explicit zero.
How This Calculator Works
Formula
Area costs = fixed area costs + variable area costs- Both are held constant per area in this yield scenario, even if classified differently in your full enterprise budget.
Revenue = saleable yield × price + other income; costs = area costs + saleable yield × output cost- The chart and threshold cards use the same model. Its horizontal axis is harvested yield, not paid yield.
Saleable yield = harvest yield × marketable fraction- Apply both selling price and output-unit costs to the same paid quantity.
Profit = saleable yield × (price − output cost) + other income − fixed costs − variable area costs- All revenue and costs use the same area basis.
Break-even harvest yield = max(0, (area costs − other income) ÷ (marketable fraction × (price − output cost)))- Available only when price exceeds output-unit cost.
Break-even price = output cost + (area costs − other income) ÷ saleable yield- Available only for positive saleable yield. Negative thresholds are retained.
Profit margin = profit ÷ total revenue × 100- Total revenue includes enabled other income. Zero revenue makes margin unavailable.

Assumptions
- One crop and one production period on a consistent harvested-area basis; selling price, marketable fraction, other income and entered area costs stay constant while chart yield changes.
- Every saleable unit earns the same price and incurs the same output cost. Grade discounts, stepped fees and capacity constraints are not modeled automatically.
- Inputs use one currency; selecting a currency changes the label without exchange-rate conversion.
- Yield, marketability, price and costs are your scenario assumptions. Unit switching preserves physical quantities and full input precision.
Worked Example
300 fixed + 500 variable costs/ha, output cost 10/t, selling price 200/t, harvest yield 5 t/ha, 100% marketable, other income off
- Yield threshold
800 ÷ (200 − 10) = 4.210526 t/ha (4.2105263158 before display rounding). At that yield, revenue and costs both equal 842.105263/ha.
- Price threshold
10 + 800 ÷ 5 = 170/t
- Profit and margin
Revenue 1000/ha minus total costs 850/ha = 150/ha; margin = 15%.
Expected harvest is 0.7894736842 t/ha above break-even; price is 30/t above its threshold.
How to Interpret Your Results
| Condition | What It Means |
|---|---|
| Positive profit | Expected revenue covers the costs you included. Omitted costs are not recovered by this test. |
| Price at or below output cost | There is no finite break-even yield under this model, regardless of the independent price threshold. |
| Zero saleable yield | A selling-price threshold cannot be computed without a positive paid quantity. |
| Other income covers area costs | With positive unit contribution, break-even harvest yield is zero. If other income exceeds area costs, revenue already exceeds costs at zero harvest: the zero threshold is not a chart intersection. Equality gives an actual crossing at zero. A negative price threshold means included costs are already covered at a zero selling price; it is not a recommended negative sale price. |
| Positive distance from a threshold | Yield distance compares expected harvest with its threshold at the entered price; price distance compares the entered price with its threshold at the entered yield. These are separate what-if tests, not independent guarantees when yield and price both change. |
| Chart intersection outside the displayed range | The chart keeps a bounded useful yield domain around the current scenario. A distant crossing is explicitly disclosed and the threshold card remains available; the chart is not evidence that the distant yield is achievable. |
Limitations and Cautions
- This is a quick threshold calculation. Taxes, financing, labor, land rent, storage and insurance are included only if you enter them in costs. It does not predict crop yield or future prices.
- The model does not evaluate cash-flow timing, loan repayment schedules, multi-year investments, risk distributions or changing marginal costs. A positive margin is conditional on your scenario, rather than a guarantee of whole-farm profit.
- Contract moisture, quality premiums, buyer deductions and taxes require your own consistent net price and cost treatment. Do not count a fee in both a net selling price and output costs.
Common Mistakes to Avoid
Charging marketing costs to all harvested output
Use saleable output and avoid double counting the same cost in area costs.
