Which expenses stay fixed and which move with sales in an eco-friendly stationery business?

Cost classification

Break-even gets noisy when sales-linked costs are mixed with fixed overhead. In the first year, variable costs equal 17.5% of revenue before payroll and fixed overhead, so unit margin must carry the monthly base.

Expense	Cost	Break-Even Treatment	Common Mistake
Raw Materials & Ethical Manufacturing	Variable	Use 10.0% of revenue in the first year.	Treating recycled inputs as fixed overhead.
Sustainable Packaging & Fulfillment	Variable	Use 3.0% of revenue in the first year.	Ignoring packaging waste and replacement material.
E-commerce Platform & Payment Fees	Variable	Use 2.0% of revenue in the first year.	Leaving payment fees out of unit margin.
Third-Party Logistics & Shipping	Variable	Use 2.5% of revenue in the first year.	Averaging freight too low across order sizes.
Website Hosting & Maintenance	Fixed	Include $250 per month from Month 1.	Tying hosting expense to sales volume.
Software Subscriptions	Fixed	Include $300 per month from Month 1.	Missing subscription creep as tools are added.
Utilities & Internet	Semi-variable	Model the $200 monthly base, plus usage if tracked separately.	Treating every dollar as fixed.
Salaried Hires	Semi-fixed	Step payroll up by role and year as hiring starts.	Hiring before revenue covers the added payroll.

How does break-even shift from a lean launch to full capacity?

Scenario table

Lean keeps payroll lighter, so the sales bar stays lower. As marketing and staff build in Year 3 and Year 5, fixed costs rise faster than margin gains, so the monthly break-even point moves up.

Planning assumptions only; actual results can move with order mix, ad costs, and payroll timing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case (Year 1)	$162,000	$28,350	$134,000	82.5%	-$350	Very close to break-even, but a small miss still loses money.
Managed ramp case (Year 3)	$405,000	$58,725	$346,000	85.5%	$275	Small cushion here, yet higher payroll keeps the floor high.
Full capacity case (Year 5)	$497,000	$54,670	$442,000	89.0%	$330	Best cushion in the set, but fixed costs still demand steady sales.

What pushes this stationery plan below break-even?

Stress test

Base plan is tight. A 15% sales dip leaves about a $24K gap, and a 5-point margin hit or a 15% fixed-cost rise pushes break-even to $173K-$187K. If both hit together, it climbs to about $199K.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$162K	$0 gap	Stays viable only at the base break-even line.
Revenue shortfall	Monthly sales fall 15%.	$162K	$24K gap	A modest demand miss turns into a monthly loss.
Fixed-cost increase	Fixed overhead rises 15%.	$187K	$25K gap	Rent, payroll, or admin creep lifts the bar fast.
Margin pressure	Variable expenses rise 5 points.	$173K	$11K gap	Packaging, freight, or sourcing pressure hits margin first.
Combined pressure	Sales fall 15%, fixed costs rise 15%, and variable expenses rise 5 points.	$199K	$37K gap	Small misses stack up and push the plan below break-even.

What should an eco-friendly stationery founder verify before signing the lease and buying the first inventory lot?

Founder checklist

Before you lease, hire, or buy inventory, prove the business can carry the costs that push breakeven out. If the $162K monthly sales path, $30 CAC, and $409K cash need do not hold up, slow the commitment.

1Sales path$162K/mo

Verify the order plan can reach about $162K in monthly sales, because breakeven is not believable if demand stalls before Month 34.

2Inventory turn$25K

Make sure the first $25K inventory order sells through at list price, because markdowns would trap cash and slow payback.

3Lease load$10.1K/mo

Check that launch overhead stays near $10.1K a month before growth hires, or rent and base payroll will eat the margin early.

4CAC budget$30 CAC

Budget the first $40K of marketing against a $30 CAC, which buys about 1,333 new customers if the channel holds.

5Order mix1.2→2.0 units/order

Verify the basket can move from 1.2 to 2.0 products per order while packaging, fulfillment, and fees stay near 5.5% of revenue in Year 1 and 3.0% by Year 5.

6Cash cushion$409K

Keep at least the $409K minimum cash cushion, and do not add the Year 2 marketing hire until margin coverage is clear.
