Cost classification

Break-even in Month 13 only holds if fixed payroll and facility overhead stay separate from revenue-linked inputs. If you blend 4.0% feed, 2.0% packaging, 8.0% power, and the $25,000 lease, the revenue target gets distorted.

Expense	Cost	Break-Even Treatment	Common Mistake
Facility Lease/Mortgage	Fixed	Carry $25,000/month as recurring overhead before contribution margin.	Blending lease with revenue-linked growing inputs.
First-Year Core Payroll	Fixed	Use $35,833/month for Month 1 staffing before output-based margin.	Treating trained core staff as optional volume spend.
Fish Feed & Seeds	Variable	Model at 4.0% of first-year revenue.	Ignoring feed and seed pressure when yield rises.
Packaging Materials	Variable	Model at 2.0% of first-year revenue.	Holding packaging flat while harvest volume grows.
Electricity for Lighting and Climate Control	Semi-variable	Model the usage-linked portion at 8.0% of first-year revenue.	Assuming power falls fully when sales dip.
Sales & Delivery Logistics	Variable	Model at 5.0% of first-year revenue.	Letting delivery routes erode contribution margin.
Maintenance & Repairs	Semi-fixed	Start with the $3,500/month baseline and step it up with equipment scale.	Treating repairs as smooth monthly spend forever.
Professional Services	Fixed	Carry $1,200/month for accounting and legal support.	Burying required compliance planning outside overhead.

How does break-even change as the farm moves from a lean 0.5-hectare start to base and full scale?

Scenario table

Scale helps because revenue rises faster than fixed cost load, so the cushion widens from a lean monthly loss to solid profit at base and full size. The catch is simple: these gains assume the modeled harvest mix sells as planned.

These are planning assumptions, not guarantees, and results depend on selling the modeled harvest mix.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean start, 0.5 hectare	$793k	$151k	$733k	81.0%	($91k)	Still below break-even, so cost control matters.
Base plan, 1.0 hectare	$1.65m	$305k	$894k	81.5%	$448k	Break-even is covered, with a real cushion.
Full scale, 1.5 hectare	$2.56m	$461k	$958k	82.0%	$1.14m	Strong cushion if the harvest mix sells as planned.

What breaks first if sales slip or costs run hotter?

Stress test

Base first-year revenue is about $793k/month against a $905k break-even, so there’s no launch cushion. A 10% sales miss, a 10% overhead jump, or a move from 19% to 24% variable expense all push the model deeper into loss.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	Revenue stays at about $793k/month.	$905k	$112k gap	No cushion at launch.
Revenue shortfall	Revenue drops 10% to about $713k/month.	$905k	$192k gap	A small sales miss turns the loss sharply worse.
Fixed-cost pressure	Monthly overhead rises 10% to about $807k.	$996k	$203k gap	Lease and staffing pressure push the hurdle higher.
Margin pressure	Variable expenses rise from 19% to 24% of sales.	$965k	$172k gap	Electricity, feed, and delivery costs eat the margin fast.
Combined pressure	Revenue falls 10% and variable expenses rise to 24%.	$965k	$252k gap	This two-sided shock leaves the plan well below break-even.

What should you verify before signing the lease and buying the vertical aquaponics system?

Founder checklist

The model reaches break-even in Month 13, but only if the site, buyers, and cash are real before you commit. If any one of those is soft, the gap to profit widens fast.

1Lease load$25K/mo

Verify the building can carry the Month 1 facility cost before you sign, because this fixed payment hits before revenue does.

2Power margin81% CM

Check utility capacity and energy use together, since electricity is 8% of revenue and the Year 1 variable stack leaves about 81% contribution margin before fixed costs.

3Water backupPre-stock

Test water access, filtration, recirculation, and backup systems before stocking fish, because a startup failure here can stop harvests and damage the launch.

4Buyer demand$793K/mo

Secure buyers for specialty lettuce mix, arugula, basil, cilantro, and tilapia before you count first-year sales, or the break-even case is too optimistic.

5Route test5% rev

Run delivery routes and pack-out tests before scaling, because logistics only stay near 5% of revenue when route density and handoffs work.

6Cash runway-$3.4M

Hold enough working capital for the first-year gap and staffing ramp, since minimum cash bottoms at about negative $3.4M in Month 13 and early expansion to 10 hectares is too risky.
