Which expenses are fixed and which move with sales for this paddle board rental model?

Cost classification

Break-even gets more reliable when recurring overhead stays fixed and sales-linked spend reduces contribution margin. The main risk is treating cleaning, repairs, utilities, or instructor labor as fully fixed when rental volume drives part of the spend.

Expense	Cost	Break-Even Treatment	Common Mistake
Property Lease ($20,000/month)	Fixed	Include the full monthly lease in the fixed overhead hurdle.	Spreading lease across rentals and hiding the true monthly target.
Insurance ($2,500/month)	Fixed	Include as recurring fixed overhead during the planning range.	Leaving it out because it does not track each rental.
Utilities ($4,000/month)	Semi-variable	Model a base monthly charge plus usage tied to operating activity.	Treating the full bill as fixed even when usage rises with traffic.
Cleaning Services ($2,500/month)	Semi-variable	Keep a base service level, then flex extra cleaning with rental volume.	Assuming cleaning never changes as guest and equipment use grows.
Security ($1,200/month)	Semi-fixed	Hold steady until hours, site coverage, or operating scale steps up.	Modeling security as a per-rental charge instead of a capacity step.
Marketing & Sales (7% of revenue in first year)	Variable	Deduct from revenue before calculating contribution margin.	Putting sales spend in fixed overhead and overstating margin per rental.
Activity Supplies & Maintenance (3% of revenue in first year)	Variable	Deduct as volume-linked operating spend tied to rentals and activities.	Treating repairs and supplies as fixed while usage drives wear.
Water Sports Instructor wages ($96,000/year in first year)	Semi-fixed	Include staffing in fixed overhead until schedule or FTE needs step up.	Assuming every instructor hour varies perfectly with each rental.

How does break-even change across lean, base, and full utilization?

Scenario table

Fixed costs stay near $815k a month, and variable costs are about 18% of revenue. CM ratio means the share left after variable costs, so moving from 45% to 70% utilization shifts the model from a loss to a clear cushion.

Planning assumptions only; actual break-even will move with demand, pricing, and staffing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean 45% utilization	$823k	$148k	$815k	82%	-$139k	About 17% below break-even, so coverage is weak.
Base 58% utilization	$1.06m	$192k	$815k	82%	$57k	About 7% above break-even, so the cushion is still thin.
Full 70% utilization	$1.28m	$231k	$815k	82%	$237k	About 29% above break-even, so the model has room.

What breaks the break-even plan for a paddle board rental?

Stress test

Here’s the quick math: about $1.695m in monthly revenue supports a $701k cushion over a $995k break-even. A 10% sales miss, a 10% fixed-cost jump, or a 5-point margin hit cuts that buffer fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$995k	$701k cushion	Healthy cushion in the base plan.
Revenue shortfall	Revenue falls 10%.	$995k	$531k cushion	Weak bookings cut the buffer fast.
Fixed-cost pressure	Fixed costs rise 10%.	$1.09m	$601k cushion	Higher lease, staffing, or insurance costs bite first.
Margin pressure	Variable expenses rise from 18% to 23%.	$1.06m	$636k cushion	Discounting, board damage, and weather cancellations eat margin.
Combined pressure	Revenue falls 10%, fixed costs rise 10%, and margin drops to 77%.	$1.16m	$361k cushion	The cushion shrinks hard, so one more miss gets dangerous.

Can this paddle board rental prove enough demand before you sign the access agreement and buy the fleet?

Founder checklist

Only sign the access agreement if you can prove paid rentals before the lease and fleet spend hit. The model shows break-even in Month 1, but cash still falls to a $742,000 minimum in Month 6, so demand, staffing, and board buys need to be tested first.

1Demand Proof$8K/yr

Verify nearby paid rentals can clear the rental-only revenue line before you lock the site, because a business stuck near $8,000 a year cannot carry the fixed base.

2Fixed Load$35.4K/mo

Check the monthly overhead stack from lease, tax, insurance, utilities, admin, IT, security, and cleaning, since that cost lands before a single board goes out.

3Margin Mix90% CM

Keep marketing at 7% and activity supplies plus maintenance at 3% so each rental leaves about 90% contribution margin to pay fixed costs.

4Staffing Ramp$96K/yr

Match Water Sports Instructor hours to real board use, because Year 1 pay starts at $96,000 and empty shifts break the math fast.

5Cash Cushion$742K

Hold enough cash to reach Month 6, when the model bottoms at $742,000, or the buildout can outrun the launch.

6Scale GateMonth 1

Only add more boards after the first operating month confirms the break-even pace, so you do not trap cash in inventory that sits idle.
