Which fertilizer store expenses are fixed, semi-fixed, semi-variable, or tied to sales?

Cost classification

Break-even gets useful only when each expense behaves the way the model says it does. Here, rent sets the monthly floor, payroll steps up with staffing, and product costs move with sales.

Expense	Cost	Break-Even Treatment	Common Mistake
Store Lease/Rent	Fixed	Include $3,500 per month in overhead from Month 1 through Month 60.	Treating rent as flexible after the lease is signed.
Store Manager	Semi-fixed	Include $5,000 per month based on the $60,000 annual salary and 1.0 FTE.	Ignoring the salary floor when monthly sales are slow.
Horticultural Expert	Semi-fixed	Model staffing in steps, starting at 0.5 FTE in the first year and rising later.	Staffing ahead of traffic before buyer conversion supports it.
Utilities	Semi-variable	Use the $400 monthly base, then watch usage pressure as store traffic rises.	Underbudgeting seasonal load for lighting, water, and climate control.
Wholesale Product Purchases	Variable	Apply 14.0% of first-year sales as the product purchase burden.	Confusing inventory buys with gross profit.
Packaging and Handling	Variable	Apply 2.0% of first-year sales because bags, labels, and handling rise with orders.	Leaving small order-linked costs out of margin.
Payment Processing Fees	Variable	Apply 1.5% of first-year sales for card and checkout fees.	Ignoring card mix when more buyers pay electronically.
Marketing Campaign Spend	Variable	Apply 2.5% of first-year sales as demand spend tied to revenue growth.	Cutting demand spend too early and then missing traffic targets.

How does break-even shift from a lean to a full fertilizer store setup?

Scenario table

More traffic, higher conversion, and more units per order lift revenue faster than rent and payroll, so break-even gets easier as the store scales. The base case is the pivot, and the model reaches break-even around Month 26.

Planning figures are model assumptions, not guarantees.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean store, Year 1	$9.3k	$1.9k	$14.7k	80.0%	-$7.2k	Still below break-even; fixed payroll and rent outrun sales.
Base store, Year 2	$20.1k	$3.9k	$17.3k	80.8%	-$1.0k	This is the pivot point; the model reaches break-even around Month 26.
Full store, Year 3	$39.3k	$7.2k	$19.2k	81.6%	$12.9k	Clear cushion; profit can absorb normal traffic swings.

What breaks the break-even plan for a fertilizer store?

Stress test

Year 1 sales are about $113,000, so the plan is already roughly $71,000 below break-even. The biggest risks are slower traffic, weaker conversion, higher wholesale costs, and payroll or rent rising before Month 26.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$184,000	$71,000 gap	Year 1 sales still sit below break-even.
Revenue shortfall	First-year conversion slips from 12% to 10% as weekday traffic weakens.	$184,000	$88,000 gap	A sales miss widens the cash gap fast.
Fixed-cost increase	Monthly overhead rises by $1,000 from payroll or rent creep.	$199,000	$86,000 gap	Extra overhead pushes break-even much higher.
Margin pressure	Contribution margin slips from 80% to 79% as wholesale purchases run above 14% of sales.	$186,000	$73,000 gap	Even a 1-point margin drop lifts break-even.
Combined pressure	Monthly overhead rises by $1,000 and contribution margin slips to 79%.	$201,000	$88,000 gap	This is the tightest case and leaves little cushion.

Can this fertilizer store prove enough traffic, ticket size, and cash runway before you sign the lease?

Founder checklist

No, not yet. At 410 weekly visitors, 12% conversion, and a $43.80 AOV, first-pass monthly sales are about $9.3K, which is below the $14.7K fixed load.

1Traffic Base410/wk

Verify the store can draw 410 weekly visitors in Year 1, because that is the traffic base the lease must support.

2Buyer Rate12%

Hold visitor-to-buyer conversion at 12% or better, since weaker conversion cuts orders faster than rent can flex.

3Ticket Size$43.80

Check that the Year 1 mix and 1.5-unit basket produce about $43.80 per order, because ticket size sets sales per customer.

4Supply Cost80% CM

Keep wholesale buying near 14% and packaging at 2%, plus processing and marketing at 4%, so contribution margin stays near 80% before fixed costs.

5Fixed Load$14.7K/mo

Hold Year 1 overhead near $14.7K a month before owner pay, and do not add Retail Associate 2 until repeat demand is visible in Month 19.

6Cash Runway$567K

Fund the $25K build-out, $10K fixtures, $15K inventory, and $30K van while keeping cash above the $567K minimum in Month 28, and treat Month 26 as the break-even target.
