Which snorkeling tour expenses are fixed, and which move with sales?

Cost classification

Break-even is only useful if fixed costs stay fixed and sales-linked costs move with bookings. In the first operating year, fixed overhead keeps running through slow weather weeks, while fuel, gear upkeep, and booking fees rise with tour revenue.

Expense	Cost	Break-Even Treatment	Common Mistake
Dockage and Mooring Fees	Fixed	Include $2,200 per month before calculating required tour revenue.	Cutting it in slow weather weeks.
Commercial Marine Insurance	Fixed	Include $1,400 per month as recurring overhead from Month 1.	Treating insurance as optional when bookings dip.
Professional Permits and Licenses	Fixed	Include $350 per month across the operating period.	Spreading permits only across peak-season departures.
Boat Fuel and Oil	Variable	Model at 5.5% of revenue in the first operating year.	Using one flat monthly fuel bill.
Snorkel Gear Maintenance and Replacement	Variable	Model at 2.0% of revenue in the first operating year.	Ignoring wear from higher guest counts.
Credit Card and Booking Fees	Variable	Model at 3.0% of revenue because fees rise with paid bookings.	Putting payment fees below the line.
Marine Naturalist Guide Labor	Semi-variable	Start with 2.0 FTE in the first year, then add guide coverage as departures rise.	Treating all guide labor as fixed salary.
Marketing and Social Media Management	Semi-fixed	Use $1,800 per month until a larger seasonal campaign is added.	Assuming marketing rises smoothly with each booking.

How does break-even change from launch to full season for this snorkeling tour company?

Scenario table

Break-even improves as guest volume rises because dock, insurance, and staffing costs move slowly while revenue grows faster. By Year 2 the model covers overhead; by Year 5 it has a wider cushion.

Planning case only: these figures are model assumptions, not guarantees.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Launch case	$37.1K	$10.4K	$27.6K	72.1%	-$1K	Still below cushion, so break-even risk stays high in launch.
Base case	$50.7K	$13.5K	$29.3K	73.3%	$8K	Clears overhead and shows the first steady break-even cushion.
Full season case	$86.2K	$23.1K	$38.4K	73.2%	$25K	Best cushion, but higher crew and fuel still matter.

What pushes this snorkeling tour business below break-even?

Stress test

The base case is close, with about a $29K monthly cushion on roughly $371K of planned revenue. A 10% booking drop, 10% higher fixed costs, or heavier fuel and commission pressure can erase that fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change in bookings, fixed overhead, or commission mix.	$342K/month	$29K cushion	Base case stays barely above break-even.
Revenue shortfall	Monthly bookings fall 10% below plan.	$342K/month	$8K gap	A small demand slip turns profit into loss.
Fixed-cost increase	Fixed overhead rises 10% across dockage, insurance, and payroll.	$377K/month	$6K gap	Overhead creep moves break-even above plan revenue.
Margin pressure	Fuel and commission pressure rises from 195% to 245%.	$365K/month	$6K cushion	Higher variable costs squeeze contribution margin.
Combined pressure	Bookings fall 10% while fixed and variable pressure both rise.	$402K/month	$68K gap	Weak bookings, weather, and cost pressure push the business well below break-even.

Can you prove the snorkeling route will fill trips before you lock in the boat, dock, crew, and gear?

Founder checklist

Don’t lock in the boat, dock, and crew until Year 1 demand and cash cover the fixed load. The model needs 2,400 half-day reef guests, 850 sunset guests, 80 private charters, and a $709K cash floor before breakeven in Month 13.

1Booking proof3,330 trips

Verify the first-year route can carry 2,400 half-day reef guests, 850 sunset guests, and 80 private charters through real departures, not hopeful marketing.

2Fixed load$7.4K/mo

Check the fixed base at $2,200 dockage, $1,400 insurance, $1,800 marketing, $450 software, $1,200 storage, and $350 permits, because that cash leaves every month.

3Fee drag80.5% CM

Keep direct bookings high, because Year 1 direct costs are about 19.5% of revenue from fuel, gear upkeep, referral fees, and booking fees.

4Crew ramp5.0 FTE

Hold staffing to the Year 1 plan of one operations manager, one lead captain, two marine naturalist guide FTEs, and one customer service coordinator until actual departures support more payroll.

5Launch capex$241.5K

Pressure-test the opening spend on the $145K boat and $12K safety electronics before you buy, because the full launch package is a large cash call.

6Cash floor$709K

Plan for the Month 13 low point at $709K, because payback does not arrive until Month 49 and early cash gets tight before the model turns.
