Do not commit to the lease, opening stock, or first payroll ramp until the store can support Year 1 traffic, margin, and cash needs. If the traffic, conversion, and reorder rhythm are not measurable yet, break-even is still a guess.
1Demand proof100 Sat / 8.0%Verify the store can reach 100 Saturday visitors in Year 1 and hold 8.0% conversion, because that demand base has to support the lease and payroll before break-even is real.
2Lease load$3.9K/moCheck the lease against $3,500 rent plus $400 utilities, because this $3.9K monthly load starts on day one and does not wait for sales to ramp.
3Launch spend$83.0KFund the $83.0K opening spend for build-out, fixtures, inventory, POS, security, signage, website, office equipment, and launch marketing before reserve cash is touched.
4Contribution margin80.5% CMKeep the Year 1 mix near 40% bras, 30% panties, 20% nightwear, 5% shapewear, and 5% accessories, because about 80.5% stays after wholesale inventory, inbound shipping, processing, and sales commissions.
5Payroll ramp$11.25K/moMake sure the Year 1 team can handle fitting-room flow and weekend peaks at $11,250 per month of payroll, because 100 Saturday visitors can turn into lost sales when service slows.
6Cash cushion$466K minTrack opening cash against the $466K minimum and the Month 36 low point, because cash gets tight long before the 53-month payback window closes.
