Which private island resort expenses are fixed, and which move with bookings?

Cost classification

Break-even gets reliable only when the $430,000 monthly overhead stays separate from booking-linked spend. Staffing adds $1.595 million in first-year semi-fixed labor, while food, amenities, and transfers move with guest revenue.

Expense	Cost	Break-Even Treatment	Common Mistake
Utilities & Infrastructure	Fixed	Include in the $430,000 monthly overhead from Month 1.	Treating desalination and power as optional.
Property Maintenance	Fixed	Plan as $80,000 per month before occupancy upside.	Waiting for failures instead of funding upkeep.
Marketing & Brand Mgmt	Semi-fixed	Use the $40,000 monthly baseline, then add campaign spikes.	Assuming marketing drops to zero in low season.
Security Services	Fixed	Include $60,000 monthly security services in overhead.	Flexing security too tightly with occupancy.
Gourmet Food & Beverage	Variable	Model at 6.0% of first-year revenue.	Burying chef payroll inside food spend.
Luxury Guest Amenities	Variable	Model at 1.5% of first-year revenue.	Treating welcome stock as pure overhead.
Logistics & Transport	Variable	Model at 7.0% of first-year revenue.	Ignoring boat fuel, transfers, and guest movement.
Staffing	Semi-fixed	Use $1.595 million in first-year payroll, then step up with service scale.	Flexing trained labor as if it moves per booking.

How does break-even change across lean, base, and full-service island resort scenarios?

Scenario table

From 45% to 72% occupancy, revenue rises, but staffing and guest-service costs rise too, so the break-even line barely moves. Lean has the tightest cushion; full-service has the widest.

Planning assumptions only; actual results will move with occupancy, guest mix, and service costs.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$2.96M	$518k	$562.9k	82.5%	$1.88M	Revenue sits above the ~$683k break-even mark, but the cushion is tight.
Base maturity case	$4.30M	$689k	$580.4k	84.0%	$3.03M	Revenue stays above the ~$691k mark, with a steadier cushion.
Full-service premium case	$5.10M	$750k	$599.2k	85.3%	$3.76M	Revenue clears the ~$702k mark and gives the widest cushion.

What breaks the break-even plan for this island resort?

Stress test

The base plan clears break-even, but the cushion narrows fast if occupancy softens or island logistics get pricier. The main watch-outs are weaker bookings, higher transport spend, and the Month 5 cash trough.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$682,323	$2,281,818 cushion	Base case clears break-even by a wide margin.
Revenue shortfall	Occupancy drops from 45.0% to 35.0%.	$682,323	$1,623,120 cushion	Weaker bookings cut revenue, but fixed costs still get covered.
Fixed-cost pressure	Monthly fixed costs rise to $599,167 as staffing expands.	$702,907	$2,261,234 cushion	Payroll and overhead growth lift the break-even bar, so cost control matters.
Margin pressure	Variable expenses stay at 17.5% instead of easing to 14.7%.	$726,263	$2,237,878 cushion	Higher service and logistics spend lowers contribution margin and pushes break-even up.
Combined pressure	Occupancy falls to 35.0%, fixed costs reach $599,167, and variable expenses stay at 17.5%.	$726,263	$1,579,181 cushion	A booking miss plus transport and maintenance pressure can pull cash toward the Month 5 low point.

What should you verify before you lock the island build?

Founder checklist

Before you lock major capex, prove the island can open with site control, guest transfer, utilities, and staffing all ready. The model shows breakeven in Month 1, but you still have to absorb a $14.15M build, $1.595M Year 1 payroll, and a Month 5 cash trough of -$1.2M.

1Site Control$14.15M build

Secure site control before any major capex, because the full island build totals $14.15M and you should not spend against an asset you do not control.

2Guest AccessBoat route

Confirm guest transfer routes and boat capacity now, since every arrival, supply run, and staff shift depends on that link.

3Utilities ReadyPower + water

Verify power generation, desalination, security, and emergency cover before launch; if one piece slips, service quality and room readiness drop fast.

4Staffing Ramp$1.595M/yr

Lock the Year 1 team and FTE ramp before build spend, because payroll is already about $1.595M a year.

5Demand Proof45% occupancy

Test bookings before you scale marketing spend, and price weekday and weekend stays by the four accommodation classes so the 45% Year 1 occupancy path is real.

6Unit Economics82.5% CM

At an 82.5% contribution margin, you need about $683K a month to cover the $562.9K fixed load, and that is separate from the $14.15M build and the Month 5 cash trough of -$1.2M.
