Cost classification

Break-even gets more reliable when sales-linked costs stay below revenue and monthly overhead is kept separate. In the first year, model $6,800 of fixed overhead plus about $18,542 of monthly wages before volume-based costs.

Expense	Cost	Break-Even Treatment	Common Mistake
Warehouse rent	Fixed	Include in the $6,800 monthly fixed overhead from Month 1 through Month 60.	Spreading rent across units sold and hiding the true monthly hurdle.
Software subscription fees	Fixed	Include as a recurring $900 monthly overhead item in the break-even base.	Treating the subscription as a one-time setup expense instead of monthly overhead.
Wholesale product purchases	Variable	Apply as 9.0% of first-year revenue, declining to 8.5% by the fifth year.	Using a flat dollar amount and missing stock needs as sales rise.
Payment processing fees	Variable	Apply as 3.0% of first-year revenue, declining to 2.5% by the fifth year.	Leaving card fees out of contribution margin.
Vehicle fuel and maintenance	Semi-variable	Model the usage-linked portion against sales activity; first-year assumption is 4.0% of revenue.	Treating fuel and route wear as fixed even when restocking trips increase.
Marketing for location acquisition	Variable	Apply as 3.0% of first-year revenue, declining to 2.5% by the fifth year.	Putting all location growth spend into fixed overhead.
Route driver wages	Semi-fixed	Include $3,750 per month in the first year, then step up as staffing rises to 1.5 FTE in the second year.	Treating restocking labor as fully fixed while route count grows.
Maintenance technician wages	Semi-fixed	Include about $2,083 per month in the first year, then step up as coverage moves from 0.5 FTE to 1.0 FTE in the second year.	Waiting to add labor until machine downtime already hurts sales.

How does break-even change from a lean route to a fuller vending machine route?

Scenario table

Break-even moves fast because fixed route costs stay high while sales scale with traffic. The lean case just covers overhead, the base case adds a cushion, and the fuller route turns that same cost base into strong profit.

Planning cases only; real results will move with site traffic, refill speed, and product mix.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean route build	$31.3k	$5.9k	$25.3k	81%	$0	Revenue is just enough to cover overhead, so small misses turn it negative.
Base route, Year 1 mix	$48.7k	$9.3k	$25.3k	81%	$14.1k	This has a clean cushion, so modest traffic dips still leave profit.
Full route, Year 3 mix	$160.2k	$29.0k	$37.6k	82%	$93.6k	This is well past break-even, but fuel, stocking, and site costs still need control.

What breaks the vending machine break-even plan?

Stress test

The base plan clears break-even, but the cushion gets thin fast if traffic weakens or costs drift up. At an 81% contribution margin, a 35% revenue drop, 15% higher fixed costs, or 24% variable expenses can erase most of it.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$31,300	$17,400 cushion	The base case works, but the buffer is not huge.
Revenue shortfall	Revenue falls 20% to about $38,950.	$31,300	$7,700 cushion	Still profitable, but the cushion nearly halves.
Fixed-cost rise	Fixed costs rise 15% to about $29,143.	$36,000	$12,700 cushion	Higher overhead pushes break-even up fast.
Margin squeeze	Variable expenses rise to 24.0% of sales.	$33,300	$15,400 cushion	Fees, shrink, or extra service trips can eat margin.
Combined pressure	Revenue falls 35%, variable expenses reach 24.0%, and fixed costs rise 15%.	$38,300	$6,700 gap	This can flip monthly profit to a loss.

What should a vending founder verify before buying machines and signing locations?

Founder checklist

The model only works if traffic, site access, and cash line up before you spend. With breakeven in Month 8 and minimum cash at $696K, delay machine buys and route hires until the sites and volume are real.

1Traffic Proof5.5k/4.5k visits

Verify weekday and weekend traffic against the Year 1 model of 5,500 weekday visitors and 4,500 weekend visitors, because break-even depends on real footfall, not hopeful placement.

2Fixed Load$25.3K/mo

Add the $6.8K fixed overhead to Year 1 wages and confirm the route can carry about $25.3K per month before you sign more sites.

3Margin Mix81% CM

Check that chips, soda, protein bars, and water can hold the Year 1 81% contribution margin after 9.0% product cost and 10.0% in other variable fees.

4Route Ramp20 units

Map restocks and repairs for the first 20 machines, because Year 1 staffing already assumes 1.0 route driver FTE and 0.5 maintenance FTE.

5Cash Buffer$696K

Keep at least $696K of cash through Month 8, because the model does not hit breakeven until Month 8 and Year 1 EBITDA is negative $15K.

6Launch ReadyBefore open

Lock written placement permission, cashless payment hardware, and wholesale supply terms before launch, because the first sale only counts if the machine can take payment and stay stocked.
