Which expenses are fixed and which move with sales for this online business?

Cost classification

Break-even is only useful if fixed overhead, sales-linked fees, and scale-driven spend are kept separate. Mix them up, and Month 20 break-even can look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
E-commerce Platform Fees	Fixed	Include $2,000 monthly in fixed overhead from Month 1 through Month 60.	Treating the platform fee as order-based.
Legal & Accounting Services Retainer	Fixed	Include $1,200 monthly in overhead before calculating contribution coverage.	Leaving retainers out of monthly break-even.
Co-working Space Rent	Fixed	Include $1,500 monthly once committed, even if sales are slow.	Treating rent as optional after signing up.
Product Sourcing & Manufacturing	Variable	Apply as 8.0% of first-year revenue, then lower by year per the model.	Using gross revenue as if it were profit.
3PL Fulfillment & Packaging Materials	Variable	Apply as 4.0% of first-year revenue because fulfillment and packaging rise with orders.	Ignoring packaging and fulfillment drag.
Payment Processing Fees	Variable	Apply as 2.5% of first-year revenue, tied directly to sales volume.	Treating processor fees as fixed overhead.
Annual Marketing Budget	Semi-variable	Model $50,000 in the first year with $35 customer acquisition cost, then scale only with proven conversion.	Locking paid spend before conversion proof.
Wages and Contractor Roles	Semi-fixed	Start with Founder/CEO at $100,000 annual, then add specialist roles as revenue coverage improves.	Adding hires before contribution can carry payroll.

How does break-even shift from a lean launch to base and full-scale online operations?

Scenario table

Higher ad spend, tools, and payroll lift the monthly break-even bar even as the contribution margin improves. Here’s the quick math: the business needs more revenue to cover a bigger fixed base.

Planning assumptions only. Real results can shift with traffic, product mix, and hiring timing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch plan	$30.8k	$5.4k	$25.4k	82.5%	-$212k	Needs about $30.8k a month to break even.
Base year 2 plan	$47.8k	$7.9k	$39.5k	83.5%	-$12k	Month 20 is the crossover point, but cushion stays thin.
Full year 3 growth plan	$68.6k	$10.5k	$58.1k	84.7%	$1.1M	Scale clears break-even, so the model turns strongly positive.

What breaks the break-even plan if revenue slips or costs creep up?

Stress test

The base plan is at break-even, so there’s no cushion. A 10% revenue miss, a 10% fixed-cost jump, or a 3-point margin squeeze each push the model into a monthly loss fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$307,000	$0 cushion	No cushion means even a small miss hurts cash.
Revenue shortfall	Monthly revenue falls 10% from the base plan.	$307,000	$31,000 gap	That drop turns into about a $25,000 monthly loss.
Fixed-cost pressure	Fixed spend rises 10% from the $254,000 base.	$338,000	$31,000 gap	Overhead creep pushes break-even above the current run rate.
Margin pressure	Variable expenses rise 3 points, cutting contribution margin to 79.5%.	$320,000	$13,000 gap	Small cost slippage is enough to break the monthly plan.
Combined pressure	Revenue falls 10%, fixed spend rises 10%, and variable expenses rise 3 points.	$351,000	$75,000 gap	Together, these shocks create a steep loss and drain cash fast.

What should the founder verify before locking the $50K Year 1 marketing budget and early hires?

Founder checklist

Before you commit to paid scale, verify that CAC stays near $35, AOV holds near $64.98, and cash can carry the early loss period. If those three don’t hold, the business is not ready to scale.

1CAC Proof$35 CAC / $64.98 AOV

Verify paid acquisition can stay near $35 CAC while the Year 1 mix holds AOV near $64.98, or the $50K marketing budget will not buy enough demand.

2Fixed Load$14.7K/mo

Check the $6.4K monthly operating overhead plus the $100K founder salary, because break-even has to cover owner income before you add growth spend.

3Margin Stack82.5% CM

Track product sourcing at 8.0%, fulfillment at 4.0%, payment fees at 2.5%, and support at 3.0%, since those Year 1 costs leave an 82.5% contribution margin before fixed costs.

4Hiring RampMonth 13+

Keep Year 1 lean with founder time plus 0.5 FTE marketing and 0.5 FTE operations, then add support only when revenue can carry the Month 13 staffing ramp.

5Launch Spend$73K upfront

Fund the $73K one-time website, equipment, inventory, brand, laptop, photography, and SEO spend separately, so launch cash does not get confused with monthly break-even.

6Cash Runway$589K by Month 21

Plan for at least $589K of cash through Month 21, because EBITDA is -$212K in Year 1 and the model does not reach break-even until Month 20.
