Which sweet potato farm expenses are fixed and which move with sales?

Cost classification

For this farm, break-even gets fragile if revenue-linked crop costs are treated as fixed or step labor is treated as fully variable. Land and facilities set the monthly floor; inputs, packaging, freight, and commissions shape contribution margin.

Expense	Cost	Break-Even Treatment	Common Mistake
Land lease	Fixed	Use hectares times monthly lease rate. In the first year, that is 20 hectares × $150, or $3,000 per month.	Modeling rent per pound sold instead of as a monthly capacity charge.
Facility lease for curing, storage, and packing	Fixed	Include $5,000 per month in fixed overhead from Month 1 through the forecast period.	Leaving the facility out until harvest, even though the lease starts before sales.
Utilities for facilities	Semi-variable	Start with the $1,500 monthly base, then stress-test usage risk during curing, storage, and packing months.	Treating the full utility bill as fixed when higher handling volume can lift usage.
Farm inputs	Variable	Use 10.0% of first-year revenue for slips, fertilizers, crop protection, water, and fuel.	Budgeting inputs as a flat annual amount while revenue and cultivated area scale.
Packaging materials	Variable	Use 3.0% of first-year revenue because packaging moves with packed and sold crop volume.	Forgetting that fresh-market sales need more packaging as volumes rise.
Logistics and cold storage	Variable	Use 5.0% of first-year revenue for freight and cold storage tied to shipment volume.	Counting freight as overhead instead of a selling-volume expense.
Sales commissions and marketing	Variable	Use 2.0% of first-year revenue because this line scales with sales activity.	Keeping commissions fixed, which overstates margin as revenue grows.
Seasonal farm workers	Semi-fixed	Model labor in FTE steps: 5.0 in the first year, rising to 9.0 by Year 5.	Spreading labor evenly per pound instead of adding workers when acreage steps up.

How does break-even shift as sweet potato acres, loss, and price mix move from lean to full scale?

Scenario table

Here’s the quick math: Year 1 prices run from $0.60 to $1.60 per pound, so the mix matters as much as acres. As loss falls from 80% to 72%, fixed overhead gets covered and the farm moves from below break-even to above it.

Planning numbers only; actual results will move with yield, pricing, and sales timing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Year 1, 20 hectares	$4.06M	$813k	$7.24M	80.0%	-$3.99M	Below threshold; fixed costs still outrun cash generation.
Base Year 4, 50 hectares	$11.98M	$2.22M	$9.42M	81.5%	$347k	Near threshold; the mix almost covers fixed overhead.
Full Year 5, 60 hectares	$15.11M	$2.72M	$10.05M	82.0%	$2.34M	Above threshold; pricing and mix leave a cushion.

What breaks the break-even plan first for this sweet potato farm?

Stress test

Here’s the quick math: Year 4 revenue is $1.198M, estimated fixed costs are about $843k, and break-even revenue lands near $1.034M. That leaves only a $164k cushion, so a 10% sales slip or a 5-point margin hit can erase it fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$1.034M	$164k cushion	Current plan clears break-even, but the cushion is thin.
Revenue shortfall	Revenue falls 10% from weaker fresh-market pricing and lower packout.	$1.034M	$44k cushion	A small sales dip almost wipes out the buffer.
Fixed-cost increase	Fixed overhead rises 10% across labor, storage, and admin.	$1.138M	$60k cushion	Overhead inflation cuts the cushion fast.
Margin pressure	Contribution margin falls 5 points to 76.5% from freight, storage loss, and sales pressure.	$1.101M	$97k cushion	A 5-point margin squeeze leaves little room.
Combined pressure	Revenue falls 10%, fixed costs rise 10%, and margin falls to 76.5%.	$1.212M	$133k gap	Three hits together push the farm below break-even.

What should a sweet potato farm verify before leasing more land and buying storage?

Founder checklist

Only commit after the land and irrigation check out, and after buyers can cover the Year 1 break-even test. The farm also needs storage ready for Month 9 and Month 10 harvest and enough cash to ride the Month 21 low point.

1Soil Check$3K/mo

Verify soil quality and irrigation access before signing the lease, and budget about $3K a month for 20 hectares so land cost does not outrun the crop.

2Buyer Demand$9.045M Y1

Line up fresh, processing, organic, and specialty buyers before you count the Year 1 break-even revenue test, because harvest cash only works if orders are already in place.

3Fixed Load$603K/mo

Compare committed sales to the fixed monthly overhead before you add more land or storage, or the farm will carry too much cash burn.

4Margin Check80% CM

Keep the contribution margin, the share left after variable costs, near 80%, so inputs, packaging, freight, and sales costs still leave room for fixed costs.

5Harvest ReadyMonth 9-10 / 50 FTE

Have curing, storage, and packing ready before the Month 9 and Month 10 harvest, and line up about 50 seasonal full-time equivalent (FTE) workers in Year 1 so the crop moves fast.

6Cash Cushion-$1.234M

Hold enough reserve for the Month 21 cash trough, and delay storage expansion if buyer commitments do not cover the fixed monthly overhead.
