Which drugstore expenses are fixed, and which move with sales?

Cost classification

If you tag every expense as variable, Month 3 break-even can look safer than it is. Keep fixed overhead, revenue-linked fees, and staffing steps separate so the model shows the real sales level needed to cover operations.

Expense	Cost	Break-Even Treatment	Common Mistake
Store Rent	Fixed	Include $7,500 per month in fixed overhead from Month 1 through Month 60.	Tying rent to sales instead of treating it as a monthly commitment.
Pharmacist payroll	Fixed	Include the $130,000 annual salary at 1.0 FTE in the first year.	Treating required pharmacist coverage as optional labor.
Pharmacy Technician payroll	Semi-fixed	Model staffing in steps as FTE rises from 1.0 in the first year to 2.0 by the third year.	Ignoring staffing steps and spreading labor smoothly across sales.
Retail Associate payroll	Semi-variable	Scale with traffic and store hours as FTE rises from 1.0 to 2.5 over the model.	Burying store-floor labor inside general payroll.
Utilities	Semi-variable	Start with the $800 monthly base, then review usage pressure as visits and hours grow.	Assuming utilities are fully sales-driven.
Pharmacy Supply Costs	Variable	Apply 4.0% of revenue in the first year, falling to 3.0% by the fifth year.	Putting supply usage into fixed overhead.
Payment Processing Fees	Variable	Apply 2.5% of revenue in the first year, falling to 2.0% by the fifth year.	Forgetting that card fees rise with sales volume.
Marketing & Branding	Fixed	Include $1,000 per month as recurring fixed overhead.	Mixing recurring brand spend with sales promotions.

How does break-even change as the drugstore moves from lean launch to base scale and full staffing?

Scenario table

Break-even climbs as fixed payroll steps up, even while the margin stays strong, because more staff adds cost faster than variable savings help. The lean case tests the lease, the base case tests hiring, and the full case tests capacity.

Planning case figures use model assumptions, so they help test rent, staffing, and traffic, not guarantee results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$115.4k	$12.7k	$33.7k	89.0%	$69.0k	Good for lease testing; sales clear break-even.
Base scale case	$227.7k	$22.1k	$42.1k	90.3%	$163.5k	Best for a hiring plan; cushion widens.
Full mature case	$439.5k	$37.4k	$46.6k	91.5%	$355.5k	Best for capacity planning; fixed costs are covered with room left.

What breaks this drugstore’s break-even cushion first?

Stress test

The plan breaks first if traffic slips, payroll grows before sales, or shrinkage and promotions run hot. With Year 1 fixed costs near $33,700 a month and an 89.0% contribution margin, the store has room, but a thin one, if reimbursement or vendor setup slows.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$37,900	$74,600 cushion	Year 1 sales clear break-even, but the cushion can shrink fast.
Revenue shortfall	Year 1 sales drop 20% to about $90,000.	$37,900	$52,100 cushion	Traffic softness cuts cushion by about $22,500.
Fixed-cost increase	Fixed costs rise 10% to about $37,100 a month.	$41,700	$70,800 cushion	Extra rent, payroll, or support staff pushes the floor higher.
Margin pressure	Listed variable expenses rise from 11.0% to 16.0%.	$40,100	$72,400 cushion	Shrink, fees, or promotions can erode margin faster than expected.
Combined pressure	Sales fall 20%, fixed costs rise 10%, and variable expenses rise to 16.0%.	$44,200	$45,800 cushion	Lower traffic, higher overhead, and margin loss deserve a cash check.

What should a drugstore founder verify before signing the lease and placing opening orders?

Founder checklist

Do not sign the lease or place opening orders until the store can carry $33.7K in monthly fixed cost and still match the Year 1 demand path. The model reaches breakeven in Month 3, but only if traffic, basket size, and staffing hold up.

1Lease Load$33.7K/mo

Check that $7,500 rent plus Year 1 payroll and store overhead stay inside this monthly fixed load, because higher occupancy cost pushes breakeven out fast.

2Traffic Base80/100/50

Test observed traffic against 80 weekday visitors, 100 on Saturday, and 50 on Sunday, because the store needs that flow before the lease starts to bite.

3Basket Value$104.94/order

Confirm a 45.0% visitor-to-buyer rate and 1.8 units per order, because that mix has to produce about $104.94 per order to support the model.

4Margin Stack89.0% CM

Verify that supply, shrinkage, processing, and promo costs still leave about 89.0% contribution margin, so each sale has room to cover fixed cost.

5Launch Team4.0 FTE

Lock the pharmacist, technician, retail associate, and store manager before opening, because the launch plan assumes full coverage from Month 1.

6Cash Buffer$785K

Hold at least the Month 2 cash floor and stage the $185K buildout, because renovation, equipment, opening inventory, and early shrinkage hit before breakeven.
