Which garden center expenses are fixed, and which move with sales?

Cost classification

Break-even only works if each expense follows the right driver. Treat rent as fixed, product purchases as variable, and seasonal items like utilities as usage-linked, or Month 28 break-even can look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Rent Retail Space	Fixed	Use $4,500 per month as base overhead from Month 1 through Month 60.	Flexing rent with visitors instead of treating it as a monthly hurdle.
Store Manager Payroll	Semi-fixed	Model the $65,000 salary at 1.0 FTE as a staffing layer needed to operate the store.	Spreading salaried management across each sale as if it disappears when traffic dips.
Utilities	Semi-variable	Start with the $800 monthly base, then expect water and cooling pressure to rise in busy seasons.	Calling utilities fully fixed when plant care and weather can raise usage.
Wholesale Product Purchases	Variable	Apply the sales-based rate, starting at 12.0% in the first year and falling to 9.0% by Year 5.	Using 120% by mistake, or treating the $40,000 initial inventory stock as monthly overhead.
Packaging & Freight	Variable	Apply the sales-based rate, starting at 3.0% in the first year and falling to 2.0% by Year 5.	Burying shipping materials in fixed overhead and understating each added order.
Workshop Supplies	Variable	Tie supplies to workshop revenue, starting at 1.5% in the first year and falling to 1.0% by Year 5.	Budgeting supplies as a flat line even when workshop activity changes.
POS Transaction Fees	Variable	Apply 0.8% of sales in the first year, then 0.7% from Year 2 onward.	Ignoring small card fees because they look minor per ticket.

How does break-even change from a lean to a full garden center?

Scenario table

Lean breaks even at the lowest sales level because overhead is smallest. Base is the planning anchor, and full needs the most revenue because payroll climbs faster than margin.

Planning assumptions only; actual results will move with traffic, product mix, and wage pressure.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean footprint garden center	$29,952	$5,182	$24,770	82.7%	$0	Lowest sales hurdle; overhead stays lean.
Standard independent garden center	$34,827	$5,224	$29,603	85.0%	$0	Planning anchor; payroll growth lifts the target.
Expanded assortment garden center	$39,591	$5,028	$34,562	87.3%	$0	Best margin, but the larger staff keeps break-even high.

What breaks the garden center break-even plan?

Stress test

The plan breaks even at about $29,952 a month on $24,770 of fixed costs and an 82.7% contribution margin. A 10% sales dip, higher freight or payroll, or a 3-point margin squeeze quickly turns that into a monthly loss.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$29,952	$0 cushion	No cushion; any miss turns into loss.
Revenue shortfall	Monthly sales fall 10%.	$29,952	$2,477 gap	Bad weekends and weak plant traffic hit sales first.
Fixed-cost increase	Fixed costs rise 10%.	$32,947	$2,477 gap	Payroll, rent, and utilities move the line up.
Margin pressure	Contribution margin drops 3 points.	$31,079	$898 gap	Supplier freight and plant shrink squeeze the margin.
Combined pressure	Sales fall 10%, fixed costs rise 10%, and margin drops 3 points.	$34,187	$5,765 gap	All three together push cash burn fast.

What should you verify before signing a garden center lease and locking the launch plan?

Founder checklist

Treat this as a go/no-go test on the lease, launch spend, and staffing plan. If the site cannot handle water, irrigation, drainage, parking, loading, and visibility, or if cash cannot hold the $197K floor through Month 30, the Month 28 break-even target is too fragile to trust.

1Site fit$4.5K rent

Verify the lease can handle water access, irrigation, drainage, parking, loading, visibility, and zoning, because a weak site adds fixed cost without supporting traffic.

2Launch build$205K capex

Confirm you can fund the full build-out, fixtures, POS setup, initial inventory, delivery vehicle, signage, workshop equipment, and office equipment, because the launch bill totals $205,000 before trading starts.

3Cash floor$197K

Protect the minimum cash balance through Month 30, because the model bottoms out at about $197,000 and EBITDA stays negative in Year 1 and Year 2.

4Contribution82.7%

Check that Year 1 sales keep about 82.7% after wholesale purchases, packaging and freight, workshop supplies, and POS fees, because that spread must carry rent, wages, and marketing.

5Payroll load$17.5K/mo

Verify the Year 1 staffing plan for the manager, horticultural expert, retail staff, and part-time marketing help can stay near $17,500 a month, and delay nonessential hiring if Month 28 slips.

6Traffic proof110/day

Test the floor against about 110 visitors a day in Year 1, with 200 on Saturday and 150 on Sunday, because 12% conversion only works if staff can serve the weekend rush.
