Cost classification

Your Month 3 break-even only holds if fixed overhead, fixed payroll, and project-linked percentages stay separate. In the first year, base overhead is $5,350/month, while contract designer fees at 10% and marketing at 8% move with revenue.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent / Co-working Membership	Fixed	Include $2,500/month in baseline overhead before calculating required revenue.	Scaling rent with revenue instead of keeping it stable.
Design & Project Management Software Subscriptions	Fixed	Include $500/month as recurring overhead for the full model period.	Bundling fixed software with project-specific resource fees.
Founder and Year 1 Administrative Payroll	Fixed	Include $100,000/year for the founder and $22,500/year for 0.5 admin FTE in the first year.	Leaving owner labor out, then overstating break-even profit.
Contract Designer Fees	Variable	Apply 10% of revenue in the first year as project volume rises.	Treating contractor help as fixed monthly payroll.
Design Resource Subscriptions, Project-Specific	Variable	Apply 3% of revenue in the first year because usage follows client work.	Hiding project tools inside general software overhead.
Marketing & Digital Ad Spend	Variable	Apply 8% of revenue in the first year, separate from the annual marketing budget.	Treating all marketing as fixed when the model uses 8% of revenue.
Client Travel & Site Visit Expenses	Variable	Apply 4% of revenue in the first year for client visits and project activity.	Using one flat travel allowance across all sales levels.
Hiring Step-Ups Starting Month 13	Semi-fixed	Add payroll in blocks when roles start, including the junior designer and marketing specialist from Month 13.	Spreading future hires evenly across the first year.

How does break-even shift across lean, base, and full-service launch paths for this interior decorating business?

Scenario table

Lean overhead gives the fastest cushion, the base plan sits at Month 3 break-even, and the full-service path needs more revenue because staffing costs rise faster than margin.

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

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch	$20,744	$5,186	$13,683	75%	$1,875	Deferring the assistant keeps a small cushion above break-even.
Base plan	$20,744	$5,186	$15,558	75%	$0	Matches the model’s Month 3 break-even point.
Full-service growth plan	$85,320	$21,330	$39,933	75%	$24,057	Bigger packages can cover the heavier team if volume stays steady.

What breaks the break-even plan for an interior decorating studio?

Stress test

At about $20,744 a month, the base plan clears overhead, but it is sensitive to slow closes and cost creep. A 10% revenue dip, extra site visits, contractor overuse, or paid lead costs above the $250 Year 1 CAC can erase the cushion.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change from the base case.	$20,744/month	$0 gap	The base plan clears overhead, but slack is thin.
Revenue shortfall	Bookings fall 10%, cutting revenue to about $18,670/month.	$20,744/month	$1,556 gap	Slow approvals or fewer closes erase the cushion.
Fixed-cost increase	Fixed overhead rises 10% to about $17,114/month.	$22,818/month	$2,074 gap	More rent, software, or showroom spend pushes the floor up.
Margin pressure	Total variable costs rise from 25% to 30%.	$22,226/month	$1,482 gap	Extra site visits and contractor overuse cut contribution.
Combined pressure	Bookings fall 10% and variable costs rise to 30%.	$22,226/month	$2,938 gap	A booking dip plus margin creep makes the studio fragile.

Is your interior decorating business ready to carry break-even before you sign the lease, spend on samples, or hire?

Founder checklist

Use these gates before you make the big commitment. The model hits break-even in Month 3, but cash bottoms in Month 2, so the early plan has to fund the gap first.

1Client Volume8+ clients/mo

Verify you can land at least 8 average clients a month, or the same revenue mix from $95 consultations, $110 ad hoc work, $120 full design, and $130 project management.

2Fixed Load$5.35K/mo

Check that monthly fixed overhead stays at the modeled $5,350, including the $2,500 rent line, software, insurance, legal, utilities, supplies, samples, and hosting.

3Project Margin25%

Keep project-linked costs near 25% of revenue by collecting deposits before contractor, sample, and travel spend hits the job.

4Hire GateMonth 13

Delay the junior designer and marketing hire until revenue can carry the added payroll, because those roles start in Month 13 and raise the fixed load fast.

5Cash Cushion$881K

Hold at least the modeled minimum cash of $881,000, since the cash trough lands in Month 2 and the launch build totals $46,000.

6CAC Check$250 CAC

Test customer acquisition cost (CAC) near $250 before scaling the $25,000 Year 1 marketing budget, or paid demand will outrun early revenue.
