Which boutique expenses stay fixed, and which move with sales at break-even?

Cost classification

At Month 29, break-even depends on separating true overhead from sales-driven costs. If a fixed rent bill gets modeled like inventory, or payroll gets treated as fully variable, the break-even target will look cleaner than cash reality.

Expense	Cost	Break-Even Treatment	Common Mistake
Store Rent	Fixed	Carry $4,500/month through break-even; it does not fall when sales dip.	Reducing rent as a percentage of sales.
Utilities	Semi-fixed	Start with the $350/month baseline, then review when store hours expand.	Ignoring longer hours during busier periods.
Wholesale Inventory Purchases	Variable	Use 15.0% of sales in the first break-even year; this is an operating margin input, not tax treatment.	Treating inventory as fixed overhead.
Shipping and Import Duties	Variable	Apply 2.2% of sales in the first break-even year, tied to product volume.	Leaving landed product costs below gross margin.
Payment Processing Fees	Variable	Apply 2.6% of sales in the first break-even year because fees rise with transactions.	Forgetting fees on card-heavy sales.
Marketing and Advertising	Variable	Model 7.2% of sales in the first break-even year, then test if traffic still converts.	Cutting spend without lowering visitor growth.
Store Manager	Fixed	Carry $4,000/month from the $48,000 annual salary across the planning range.	Linking manager pay to each sale.
Sales Associate	Semi-fixed	Use about $6,667/month in the first break-even year: $32,000 salary × 2.5 FTE ÷ 12.	Treating 2.5 FTE as fully flexible by day.

How does break-even change across lean, base, and full boutique formats?

Scenario table

The gap is mostly payroll and overhead. Lean clears break-even at about $20.7k a month, base at about $23.0k, and the full staffed store at about $31.0k, so lease timing should wait until traffic, conversion, and basket size support the higher floor.

Planning figures only. Actual break-even will move with traffic, conversion, basket size, and wage mix.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean pop-up launch	$20,705	$6,170	$14,535	70.2%	$0	Lowest overhead, but the sales floor is still tough.
Base storefront	$22,960	$6,842	$16,118	70.2%	$0	This is the core plan and lines up with the Month 29 break-even point.
Full staffed store	$30,984	$8,366	$22,618	73.0%	$0	This only works if traffic, conversion, and average order value support the higher sales floor.

What breaks the boutique break-even plan if sales slip or costs rise?

Stress test

The boutique is tight at the base plan, and it gets fragile fast if weekday traffic softens or markdowns rise. A 10% sales dip leaves about a $2.3k monthly gap, while higher payroll or occupancy can push the break-even target much higher.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$30,984	$0 gap	No cushion if sales land below plan.
Revenue shortfall	Monthly sales fall 10% to $27,886.	$30,984	$2,260 gap	Weak weekday traffic creates an immediate cash shortfall.
Fixed-cost pressure	Fixed costs rise 10% to $24,880.	$34,082	$3,098 gap	Rent, staffing, and overhead can outrun sales fast.
Margin pressure	Contribution margin falls to 70% from markdowns or higher card fees.	$32,311	$1,327 gap	Discounting and fees eat each sale.
Combined pressure	Sales fall 10%, margin drops to 70%, and fixed costs rise 10%.	$35,543	$5,360 gap	Slow traffic plus higher payroll can break the model.

Can you prove the boutique clears break-even before you sign the lease?

Founder checklist

Check the lease, buy plan, and staffing against the break-even math before you commit. If the boutique can’t clear about $31K a month and still survive the Month 33 cash trough, the space is too early.

1Launch traffic15-45/day

Verify the shop can draw 15 Monday visitors, 35 Friday visitors, 45 Saturday visitors, and 30 Sunday visitors so the lease is tied to real footfall.

2Buyer rate8.5% to 12.0%

Check that visitor-to-buyer conversion can rise from 8.5% in Year 1 to 12.0% in Year 3, because weak conversion makes the sales target miss fast.

3Margin mix73.0% CM

Keep the mix near 35% dresses, 25% tops, 20% outerwear, 12% jewelry, and 8% handbags so Year 3 variable load stays near 27.0% and contribution margin holds.

4Break-even$31K/mo

Test whether monthly sales can cover the fixed rent and payroll load; if they can’t reach about $31K, Month 29 break-even will slip.

5Staff rampM1/M7/M13

Start the manager in Month 1, the stylist in Month 7, and weekend staff in Month 13 so payroll grows with demand instead of ahead of it.

6Cash cushion$92K / $493K

Plan for $92K of launch spend and a $493K minimum cash need in Month 33, because the opening buildout and slow ramp can drain cash before profits turn.
