Which expenses are fixed and which move with sales in a maternity clothing store?

Cost classification

Break-even only works if each expense lands in the right bucket. Put wholesale, packaging, marketing, and shipping below sales, but keep rent and core admin fees in fixed overhead so the Month 26 break-even is not overstated.

Expense	Cost	Break-Even Treatment	Common Mistake
Apparel Wholesale Cost	Variable	Apply as 10.0% of sales in the first year, falling to 8.0% by Year 5.	Treating the initial inventory purchase as monthly fixed overhead.
Packaging Materials	Variable	Apply as 1.0% of sales in the first year, falling to 0.6% by Year 5.	Putting boxes, mailers, and inserts into office supplies.
Digital Marketing Spend	Variable	Apply as 4.0% of sales in the first year, falling to 2.0% by Year 5.	Locking ad spend as fixed even when traffic changes.
Fulfillment & Shipping	Variable	Apply as 2.5% of sales in the first year, falling to 1.5% by Year 5.	Leaving shipping out of contribution margin.
Warehouse Office Rent	Fixed	Use $1,500/month as fixed overhead across Month 1 to Month 60.	Scaling rent with units sold instead of space needs.
Platform, Software, Hosting, Insurance, Supplies, Legal and Accounting	Fixed	Use $1,650/month as recurring fixed overhead before break-even contribution.	Spreading admin subscriptions across each order like variable fees.
Utilities	Semi-variable	Model the $250/month base, then review if warehouse activity pushes usage higher.	Treating every utility dollar as sales-linked.
Store Payroll	Semi-fixed	Model staffing in steps as roles are added or full-time equivalents increase.	Assuming payroll rises smoothly with each order.

How does break-even change from a lean launch to a fully staffed maternity clothing store?

Scenario table

Higher staffing lifts fixed costs faster than margin improves, so the break-even target rises from about $160K in lean mode to $361K in the full case. The main driver is payroll, not a small change in product margin.

Planning figures only; actual break-even will move with traffic, mix, and staffing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean opening setup	$160K	$28K	$132K	82.5%	$0	Lower payroll helps, but sales still need to hold near $160K.
Core Year 3 setup	$299K	$45K	$255K	85.1%	$0	This is the middle case; overhead clears only near $299K.
Full Year 5 support setup	$361K	$44K	$317K	87.9%	$0	More support staff raises the bar, so traffic must scale hard.

What breaks this maternity clothing store’s break-even plan first?

Stress test

The plan is tight at $299K a month, with no cushion. A 10% sales dip leaves about a $29K gap, while a 10% overhead jump or a 5-point margin drop pushes break-even to about $329K or $318K.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$299K	$0 cushion	Base case sits right on break-even.
Revenue shortfall	Revenue runs 10% below plan.	$299K	$29K gap	Slower foot traffic can flip profit to loss.
Fixed-cost pressure	Fixed overhead rises 10%.	$329K	$30K gap	Overhead creep pushes the store off plan.
Margin pressure	Contribution margin falls 5 points to 80.1%.	$318K	$19K gap	Markdowns, returns, or shipping pressure squeeze margin.
Combined pressure	Revenue falls 10%, fixed costs rise 10%, and margin slips to 80.1%.	$350K	$80K gap	Lower traffic, markdowns, and higher overhead widen the gap fast.

What should you prove before signing the lease and stocking the store?

Founder checklist

Do not lock in rent, inventory, or hires until the store can turn visits into buyers and carry the lean $13.2K monthly load. The model does not reach break-even until Month 26, so cash and conversion are the real gates.

1Demand proof1.5%→3.5%

Confirm the store can lift visitor-to-buyer conversion from the first-year level to the Year 3 level before you take on fixed rent.

2Fixed load$13.2K/mo

Keep monthly overhead near the Year 1 lean load until sales can support a bigger cost base without forcing early losses.

3Unit margin82.5% CM

Track markdowns and returns each week, because Year 1 leaves about 82.5% contribution before fixed costs if pricing and mix hold.

4Inventory mix$25K buy

Tie the first inventory order to the $25K plan and the dresses, tops bottoms, postpartum wear, and trimester box mix so cash goes into the right stock.

5Hiring ramp$117.5K→$265K

Phase hiring, because annual payroll moves from $117.5K in Year 1 to $265K in Year 3 and can outrun demand fast.

6Cash runway$540K

Keep at least $540K of cash for the operating ramp, and keep the $63K startup setup separate because break-even does not land until Month 26.
