Which online pharmacy expenses are fixed and which move with sales?

Cost classification

Break-even is only reliable if fixed overhead, payroll steps, and transaction-linked costs stay separate. In this model, that discipline matters because break-even lands in Month 14.

Expense	Cost	Break-Even Treatment	Common Mistake
Platform Hosting & Maintenance	Fixed	Include $5,000 per month in fixed overhead from Month 1 through Month 60.	Spreading it across orders and making break-even look better at low volume.
Security & Compliance Software	Fixed	Include $2,500 per month in fixed overhead for the full model period.	Treating compliance software as optional when it is modeled as recurring monthly spend.
Office Rent & Warehouse Space	Fixed	Include $4,000 per month in fixed overhead while testing the sales needed to cover operations.	Linking warehouse space to each order instead of keeping it flat within the planning range.
Wholesale Medication Cost	Variable	Apply 12.0% of revenue in the first year, falling to 10.0% by the mature year.	Using one flat dollar amount and missing margin gains as the percentage declines.
Logistics & Shipping Fees	Variable	Apply 4.0% of revenue in the first year, falling to 3.0% by the mature year.	Treating all shipping as fixed monthly spend, which overstates loss at low sales and understates pressure at high sales.
Payment Processing Fees	Variable	Apply 2.5% of revenue in the first year, falling to 2.0% by the mature year.	Leaving card fees out of contribution margin, so each order looks too profitable.
Lead Pharmacist Payroll	Semi-fixed	Model by FTE: 1.0 in the first year, 1.5 in Year 3, and 2.0 in Years 4 and 5.	Assuming pharmacist coverage rises smoothly with orders instead of stepping up by headcount.
Marketing Spend Tied to CAC	Semi-variable	Use the $150,000 first-year budget with $50 CAC, then update acquisition volume as CAC declines.	Treating CAC and total marketing budget as the same flat monthly number.

How does break-even change from lean launch to full scale in an online pharmacy?

Scenario table

Break-even rises as AOV and margin improve, but it also moves up when staffing and marketing add fixed cost. Lean keeps the lowest cash risk; full scale needs the strongest sales run rate.

These are planning assumptions, not guaranteed results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$863K	$173K	$690K	80.0%	$0	Lowest hurdle, so launch discipline matters most.
Base growth case	$1.269M	$243K	$1.027M	80.9%	$0	Middle path; repeat orders must cover the bigger fixed base.
Full scale case	$1.662M	$300K	$1.361M	81.9%	$0	Best margin, but the highest sales bar and cash risk.

What breaks the online pharmacy break-even plan first?

Stress test

The base plan sits right on the line: $690K of fixed spend and an $863K break-even revenue target leave no cushion. A $10K revenue miss creates about an $8K operating gap, and added overhead or weaker repeat buying pushes the hurdle up fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$863K	$0 cushion	No cushion, so launch timing matters.
Revenue shortfall	Revenue lands $10K below the base break-even run rate.	$863K	$10K gap	Every $10K miss leaves about $8K uncovered.
Fixed-cost pressure	Monthly overhead adds $10K.	$988K	$125K gap	Added overhead lifts the hurdle by six figures.
Margin pressure	Variable expenses rise by 1 percentage point.	$873K	$10K gap	Small fee creep still moves the hurdle.
Combined pressure	Year 2 fixed spend reaches $1,027K while variable expenses improve to 19.1%.	$1.269M	$406K gap	If CAC stays above $50 or repeat orders stay under 0.8/month, this gap widens.

What should the founder verify before committing to inventory, payroll, and launch spend for the online pharmacy?

Founder checklist

Don’t lock in inventory, payroll, or launch spend until the first-year demand path can support break-even. In this model, the test is whether CAC stays near $50, repeat buying starts, and cash stays above the $171K floor through Month 14.

1Demand Proof$50 CAC, 30% repeat

Test paid demand first, because the Year 1 plan only works if CAC stays near $50 and repeat buyers reach 30% of new customers.

2Fixed Load$16.1K/mo overhead

The business already carries $5,000 hosting, $2,500 security software, $4,000 warehouse space, and the rest of the $16.1K monthly fixed load, so fund that before growth spend.

3Unit Margin80% CM

Here’s the quick math: wholesale at 12%, packaging at 1.5%, shipping at 4.0%, and payment fees at 2.5% leave about 80% contribution before payroll and rent.

4Staffing Ramp1 pharmacist + 1 tech

Keep Year 1 coverage at 1.0 FTE for the lead pharmacist and 1.0 FTE for the pharmacy technician, because fixed staffing must stay matched to order volume before you add more heads.

5Capex Stack$380K capex

Separate the $380K capex from monthly break-even math, since the $150K build, $30K system license, $40K hardware, $80K fulfillment setup, $15K security, $35K vehicle, $10K furniture, and $20K compliance setup all hit cash early.

6Cash Floor$171K, Month 14

Use Month 14 as the launch gate, and pause hiring or marketing if cash gets close to the $171K minimum, because that is where the model bottoms out.
