Which expenses stay fixed, and which move with sales in an indoor plant shop?

Cost classification

Break-even lands in Month 14 only if overhead, inventory replenishment, and staffing step-ups are separated. Treating payroll or spoilage like rent can make the shop look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Store Rent	Fixed	Use $4,000 per month as base overhead from Month 1 through Month 60.	Allocating rent per plant sold instead of holding it steady.
Business Insurance	Fixed	Use $150 per month as a stable operating expense.	Dropping insurance from break-even because it feels small.
POS & Operational Software	Fixed	Use $200 per month as recurring store systems overhead.	Mixing monthly software with one-time setup spending.
Utilities	Semi-variable	Start with $450 per month, then adjust if plant care, lighting, or foot traffic drive usage higher.	Treating all utility spend as fixed when sales volume changes store use.
Product COGS	Variable	Model at 10.0% of product revenue so replenishment moves with unit sales.	Burying spoilage or markdowns inside rent or payroll.
Workshop Materials	Variable	Model at 2.0% of workshop ticket revenue so materials scale with attendance.	Using one flat monthly supply budget even as ticket volume rises.
Payment Processing Fees	Variable	Model at 1.5% of revenue because fees rise with card sales.	Forgetting fees on planters, accessories, and workshop tickets.
Payroll	Semi-fixed	Treat first year payroll as overhead at about $15,521 per month, then step it up when staffing hours increase.	Modeling every labor dollar as variable with each sale.

How does break-even shift from a lean to a full indoor plant store?

Scenario table

Sales grow from the lean to full case, but variable costs stay at 18.5%, so the contribution margin holds at 81.5%. Higher fixed payroll lifts break-even sales from about $25.5k to $27.3k a month.

Planning assumptions only: these scenario figures help size break-even risk, but they do not guarantee future results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean plant shop	$20.4k	$3.8k	$20.8k	81.5%	-$4.2k	About $5.1k below break-even.
Base plant shop	$35.2k	$6.5k	$21.5k	81.5%	$7.2k	About $8.8k above break-even.
Full plant shop	$53.2k	$9.8k	$22.2k	81.5%	$21.1k	About $25.9k above break-even.

How much can slower foot traffic or higher overhead push break-even out?

Stress test

Year 1 sits near $255k in monthly break-even revenue on about $208k of overhead and an 81.5% contribution margin. A 10% sales miss, $20k more overhead, or margin slip to 78.5% can push break-even out fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$255k	$0 gap	Sales cover fixed overhead at plan.
Revenue shortfall	Sales run 10% below break-even.	$255k	$21k gap	Missed weekly sales targets widen the cash gap.
Fixed-cost pressure	Monthly overhead rises by $20k.	$280k	$25k gap	Payroll or rent growth pushes break-even higher.
Margin pressure	Variable costs rise from 18.5% to 21.5%.	$265k	$10k gap	More shrink or markdowns cut contribution fast.
Combined pressure	Sales run 10% below plan and monthly overhead rises by $20k.	$280k	$48k gap	Weak traffic plus heavier overhead can break the plan.

Can this indoor plant store support the lease, hiring, and inventory build before you commit?

Founder checklist

Not yet. The model shows about $245K in Year 1 revenue, -$79K EBITDA, breakeven in Month 14, and a cash low near $794K in Month 24, so the lease only works if demand, staffing, and inventory turn faster than the base plan.

1Sales path$255K/mo

A lease only works if the site can support a $255K/mo sales path; the model’s Year 5 run rate is only about $94.2K/mo, so foot traffic alone won’t close the gap.

2Staffing load$186.3K/yr

Year 1 wages are about $186.3K before rent and utilities, so add people only when sales can pay for the team, not just the space.

3Margin mix81.5% CM

With 12.0% in product and workshop COGS plus 6.5% in variable spend, you keep about 81.5% contribution margin, so spoilage and markdowns have to stay tight.

4Launch volume250/208/333/42

Year 1 demand means about 250 plants, 208 pots, 333 accessories, and 42 workshop tickets each month, so inventory buys and shelf space must match that pace.

5Cash cushionMonth 24

Cash bottoms near $794K in Month 24, so you need that reserve in place before opening or the breakeven date can slide.

6Go-liveMonth 14

Use the 5.0% promo budget to drive store visits and repeat buyers, and do not open until watering, lighting, receiving, pest checks, markdown rules, POS, delivery, repotting, workshops, spoilage tracking, and supplier terms are ready.
