Which dental evacuator supplier expenses are fixed, and which move with sales?

Cost classification

Break-even works only if fixed overhead, unit product costs, and sales-linked fees sit in the right buckets. Include recurring overhead, subtract true variable costs, and keep the $685,000 launch capex out of operating break-even.

Expense Cost Break-Even Treatment Common Mistake
Warehouse and Office Rent Fixed Include $12,000 per month in overhead from Month 1. Don’t bury rent inside product margin.
Cloud CRM and ERP Subscription Fixed Include $1,500 per month in recurring overhead. Don’t wait until the sales ramp to add it.
Sales Commissions Variable Subtract 4.0% of first-year revenue before contribution margin. Don’t treat commissions as base payroll.
E-commerce Payment Processing Variable Subtract 2.5% of first-year revenue with transaction fees. Don’t ignore card fees on reorder sales.
Product Inputs and Warranty Reserves Variable Assign materials, motors, filters, packaging, labor, and reserves per unit. Don’t average hardware and consumables blindly.
Trade Show and Event Fees Semi-fixed Model $5,000 per month, then review before each spend level. Don’t assume events scale smoothly with sales.
Customer Support Lead Staffing Semi-variable Tie staffing to installed base, warranty claims, and support load. Don’t wait until returns rise to add coverage.

How does break-even shift from a lean launch floor to a full-scale supply model?

Scenario table

Higher revenue lifts cushion faster than costs rise. The lean case sits at break-even, the base case has a healthy buffer, and the full case only works if demand actually scales.

Planning assumptions only; they show modeled break-even, not guaranteed clinic demand.
Scenario Monthly Revenue Variable Costs Fixed Costs CM Ratio Operating Profit Break-Even Signal
Lean launch floor $101k $24k $76.8k 75.9% $0 At the threshold; any miss creates loss.
Year 1 base case $214k $52k $76.8k 75.7% $85k About $113k above break-even, so there’s room.
Year 5 scale case $951k $207k $118k 78.2% $626k Big cushion, but only if scale lands.

What pushes this dental supply plan past break-even?

Stress test

The base case clears break-even by a wide margin, but the cushion shrinks fast if clinic reorders slow, hardware gets discounted, or freight and warranty costs rise. A 20% revenue drop still works, but the combined case gets tight.

Stress Case Changed Assumption Break-Even Revenue Revenue Gap Risk Signal
Current plan No change. $101k $113k cushion Base case clears break-even with room to spare.
Revenue shortfall Monthly revenue falls 20%. $101k $70k cushion Sales still cover break-even, but the cushion drops fast.
Fixed-cost pressure Fixed costs rise 10%. $111k $103k cushion Higher overhead makes volume growth more important.
Margin pressure Contribution margin falls 3 points. $105k $109k cushion Discounting or freight pressure lifts the break-even line.
Combined pressure Revenue falls 20%, fixed costs rise 10%, and margin falls 3 points. $116k $55k cushion This is the tightest case, so reorders and margins need fast repair.

What should you verify before you lock inventory, rent, and launch spend for a dental suction supplier?

Founder checklist

Break-even looks reachable in Month 2, but only if you prove clinic demand, line up suppliers, and keep launch build separate from operating cash. The model carries about $685K of launch capex and a $76.8K monthly fixed base, so early orders have to show up fast.

1Clinic Demand$13.5K/mo

Validate clinic orders before you lock $13.5K a month of search and event spend, because break-even depends on paying for real demand, not impressions.

2MOQ Fit1,500 / 250K / 1,000 / 2,500 / 400

Match supplier minimums to Year 1 volume so stock follows the forecast instead of trapping cash in slow-moving inventory.

3Lead TimesBefore launch

Map supplier lead times now and make sure finished goods land before launch, or the Month 2 break-even target slips.

4Unit Margin79.5% CM

Check that a $1,250 system still leaves about 79.5% contribution margin after unit cost and sales and payment fees, because that margin funds the fixed base.

5Fixed Load$76.8K/mo

The monthly fixed base is about $76.8K once you include rent, software, insurance, marketing, events, lab supplies, and Year 1 payroll, so the lease and hiring plan need to clear it fast.

6Cash Reserve$1.033M / 4 FTE

Protect cash through the Month 2 low point and scale support to 4 FTE before warranty and replacement volume rises, or service delays will eat margin.
