Which airport shuttle expenses are fixed, and which rise with ride sales?

Cost classification

Break-even works only if fixed overhead, step-up spending, and per-ride charges are split cleanly. Keep the $320,000 one-time setup outside monthly break-even overhead.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent	Fixed	Include $3,500 per month from Month 1 through Month 60.	Spreading rent across rides and hiding true baseline overhead.
Business Insurance	Fixed	Include $800 per month as recurring overhead.	Treating insurance as a per-trip charge when it does not scale with each ride.
Year 1 wages	Fixed	Include about $58,333 per month before volume-based expenses.	Using annual payroll totals without converting to monthly break-even load.
Year 1 buyer and seller marketing	Semi-fixed	Model $37,500 per month, then step it up as the budget increases.	Calling all marketing variable because CAC is tracked per buyer or seller.
Payment Gateway Fees	Variable	Apply 2.5% in the first year to transaction-driven revenue.	Putting payment fees in fixed overhead and overstating contribution margin.
Cloud Infrastructure per transaction	Variable	Apply 1.0% in the first year because usage follows transaction volume.	Budgeting cloud spend as flat while ride volume grows.
Driver Incentives	Variable	Apply 4.0% in the first year as a ride-volume-driven expense.	Ignoring incentive spend when testing whether new demand is profitable.
Customer Support per ride	Variable	Apply 2.0% in the first year because support workload follows completed rides.	Counting only support salaries and missing per-ride service load.

How does break-even shift from a lean airport shuttle launch to a full route schedule?

Scenario table

Ride density drives break-even here: lean utilization misses fixed cost coverage, the base case is near flat, and full utilization creates a solid cushion. Airport access, route density, and repeat business demand decide which case you hit.

Planning assumptions only; actual results depend on airport access, route density, and repeat demand.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean case	$82,125	$7,802	$103,433	90.5%	-$29,110	At 50 rides/day, losses still run.
Base case	$114,975	$10,923	$103,433	90.5%	$619	Around 70 rides/day is the break-even line.
Full utilization case	$147,825	$14,043	$103,433	90.5%	$30,349	At 90 rides/day, profit has clear cushion.

What breaks first if airport shuttle bookings slip or costs climb?

Stress test

The base case has only about a $619 cushion, so this plan is thin. A 10% booking miss, a 10% fixed-cost hike, or higher driver and support costs can push it into loss fast; target $131,435 revenue before scaling.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$114,356	$619 cushion	Thin cushion; one miss flips it.
Revenue shortfall	Monthly revenue falls 10% to $103,478.	$113,263	$9,785 gap	Weak hotel and corporate demand turns profit negative.
Fixed-cost increase	Fixed costs rise 10% to $113,776.	$124,699	$9,724 gap	Insurance and overhead creep wipe out cushion.
Margin pressure	Variable expenses rise to 125% of base.	$117,805	$2,830 gap	Driver incentive pressure eats the last cushion.
Combined pressure	Revenue falls 10%, fixed costs rise 10%, and variable expenses rise to 125% of base.	$126,711	$23,233 gap	All three pressures create a fast monthly loss.

What should you verify before you lease vehicles and hire staff?

Founder checklist

Verify airport access, real demand, and unit economics before you lock in fixed costs. The model only works if ride volume, CAC, and coverage hold up before Month 15 cash pressure and Month 16 break-even.

1Airport demand70/day

Confirm pickup rules and enough riders to support about 70 rides a day at a $54.75 average fare, or the break-even case falls apart fast.

2Ride margin49% CM

Check that each ride still leaves about $5.01 after commission, gateway, cloud, driver incentives, and support, because that margin funds the fixed burn.

3Fixed burn$65.9K/mo

Use a real insurance quote before relying on the $800 monthly placeholder, and do not add more fixed payroll until utilization can carry this burn.

4Coverage24/7

Test driver coverage for first-wave and late-night arrivals, because missed early or red-eye flights mean lost rides you cannot easily win back.

5CAC plan$30 / $1.5K

Validate buyer CAC near $30 and seller CAC near $1,500 in Year 1 before you stage the $450,000 marketing budget, or growth will be too expensive.

6Cash cushion$177K

Keep the cash reserve because the trough hits Month 15, and do not treat Month 16 break-even as guaranteed when Year 1 EBITDA is still negative.
