Cost classification

Break-even gets more reliable when lease and payroll stay separate from payouts, processing, marketing, and card fees. This matters because the model does not reach break-even until Month 39.

Expense	Cost	Break-Even Treatment	Common Mistake
Commercial Lease & Utilities, $4,500 per month	Fixed	Include the full monthly amount before calculating unit or order volume needed to break even.	Treating rent as flexible when visitor traffic is still ramping.
Store Supplies & Maintenance, $250 per month	Semi-fixed	Keep the base amount fixed, then review it when store traffic, fixtures, or maintenance needs step up.	Letting small store expenses drift without a trigger point.
Sales Associate payroll, $32,000 annual salary per FTE	Semi-fixed	Model staffing in FTE steps as coverage expands from 1.0 FTE in the first year to 3.0 FTE in the mature year.	Adding labor too early before weekday traffic supports it.
Curation Specialist payroll, $38,000 annual salary per FTE	Semi-fixed	Treat sorting and merchandising labor as capacity-driven payroll, not as a free back-office task.	Assuming donated or sourced items sort themselves.
Consignment Payouts, 2.5% of revenue in the first year	Variable	Apply the payout rate to sales, with the rate rising to 6.5% by the mature year.	Using gross sales as margin without paying consignors.
Direct Item Processing, 4.7% of revenue in the first year	Variable	Charge processing against each sale to cover handling, tagging, cleaning, and item prep.	Treating sorting labor and item prep as free.
Marketing & Advertising, 5.0% of revenue in the first year	Variable	Scale marketing with sales, then reduce the rate to 3.0% by the mature year as repeat customers grow.	Ignoring markdown-driven marketing pressure when inventory slows.
Payment Processing Fees, 2.5% of revenue	Variable	Deduct card fees from every card-based sale before measuring contribution margin.	Ignoring card fees and overstating break-even margin.

How does break-even shift across lean, base, and full thrift store setups?

Scenario table

More staff and more processing push both fixed and variable costs up, so break-even sales rise from lean to full. CM ratio is the share left after variable costs, and the model reaches break-even in Month 39 because early losses and ramp-up use cash first.

Planning assumptions only; actual results will move with traffic, pricing, inventory mix, and staffing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean owner-led launch	$240K	$35K	$205K	85.3%	$0	Lowest overhead, but traffic still has to hold.
Base staffed store	$290K	$42K	$247K	85.4%	$0	Month 39 is the break-even checkpoint.
Full merchandising build	$328K	$54K	$274K	83.6%	$0	Highest overhead, so sales need the most cushion.

What breaks the thrift store break-even plan?

Stress test

The base break-even line is $240K in Year 1. Traffic losses, higher fixed costs, and thinner margins each push that line higher, and the combined case opens a much wider cash gap.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$240K	$0 cushion	This is the minimum sales floor.
Revenue shortfall	Sales fall 10% to $216K.	$240K	$24K gap	A small traffic drop creates a fast hole.
Fixed-cost pressure	Fixed expenses rise 10% from the base case.	$264K	$24K gap	Rent or payroll creep pushes the floor up.
Margin pressure	Contribution margin compresses by 3 points.	$249K	$9K gap	More markdowns or paid marketing shrink the buffer.
Combined pressure	Sales fall 10%, fixed costs rise 10%, and margin falls 3 points.	$287K	$47K gap	Weak weekday traffic and higher costs can break the plan.

Can you prove a thrift store can clear break-even before you sign the lease and buy the fixtures?

Founder checklist

Before you commit, test whether Year 1 traffic, a 10.0% visitor-to-buyer rate, and a $51 basket can cover a fixed load near $20.5K a month. The model does not reach break-even until Month 39, so the cash plan has to survive the early loss period.

1Foot traffic670/wk

Check that local traffic can support the Year 1 visitor plan of 60 Monday through 180 Saturday, because weak traffic kills break-even before pricing does.

2Buyer rate10.0%

Test whether 1 in 10 visitors will buy; that conversion rate drives about 290 orders a month at Year 1 traffic.

3Average basket$51 AOV

Confirm the Year 1 mix of 50% clothing, 30% home goods, 15% furniture, and 5% consigned items really lands near a $51 average order value (AOV).

4Contribution margin85.3% CM

After 7.2% COGS and 7.5% variable spend, only 14.7% of sales is left before fixed costs, so margin control has to stay tight.

5Staffing load3.5 FTE, $20.5K/mo

Verify the opening team, led by the owner, manager, one associate, and half-time curation, can handle sorting and floor coverage without adding labor too early.

6Runway reserve$286K

Hold at least this much cash, because minimum cash lands in Month 43, break-even lands in Month 39, and the plan needs to absorb the $87.5K launch spend first.
