Which expenses stay fixed and which move with sales for this seafood truck?

Cost classification

Break-even is only useful if each expense is treated the right way. In the first year, fixed overhead and payroll set the monthly hurdle, while food, fees, supplies, and service-day costs move with volume.

Expense	Cost	Break-Even Treatment	Common Mistake
Lease payment	Fixed	Use $20,000 per month in break-even because it stays stable across the monthly planning range.	Lowering it when sales are slow instead of modeling the full monthly commitment.
Utilities, insurance, permits, maintenance, cleaning, marketing, and POS subscriptions	Fixed	Use $9,800 per month combined: $3,000 utilities, $2,000 insurance, $800 permits, $700 maintenance, $1,500 cleaning, $1,200 marketing, and $600 POS.	Spreading these across orders and hiding the true fixed overhead hurdle.
Year 1 payroll	Fixed	Treat payroll as $57,500 per month for Year 1 break-even unless staffing flexes by shift.	Calling all labor variable even when salaries are scheduled before sales happen.
Seafood and other inventory COGS	Variable	Model first-year COGS at 15.0% of sales, based on 10.0% beverage COGS plus 5.0% food and cigar COGS in the assumptions.	Treating inventory as fixed just because it is bought before service.
Credit card processing fees	Variable	Use 2.8% of first-year sales because processing fees rise directly with card revenue.	Putting fees in fixed overhead and overstating margin at higher volume.
Guest supplies and amenities	Variable	Use 1.5% of first-year sales for napkins, service items, and guest-facing supplies tied to order volume.	Ignoring small per-order items that add up during busy service days.
Fuel, ice, packaging, and hourly event labor	Semi-variable	Split the base operating need from the part that rises with service days, orders, or events.	Modeling every service-day expense as fixed and missing the cash drag from busier weeks.
Added crew or commissary capacity	Semi-fixed	Add these in steps when volume requires more staffing coverage or prep capacity.	Assuming capacity expands smoothly instead of jumping when the operation outgrows the current setup.

How does break-even change from lean to base to full seafood truck operation?

Scenario table

Break-even improves as the truck shifts from a lean route test to repeat demand and then to full event volume. Higher revenue and a stronger margin help fixed costs get covered sooner, so the cushion widens in the base and full cases.

Planning only: these figures are model-based assumptions, not a guarantee of actual results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean route-density test	$184.6k	$35.6k	$87.3k	80.7%	$61.7k	This is the stress test; weak route density would lift break-even fast.
Base repeat-demand test	$364.2k	$65.2k	$98.8k	82.1%	$200.2k	This is the working target; repeat demand gives a cleaner break-even cushion.
Full event-capacity test	$501.8k	$82.8k	$110.2k	83.5%	$308.8k	This is the scale case; staffing and event load need to hold to keep the cushion wide.

What breaks the seafood truck’s break-even plan if demand, costs, or margin move the wrong way?

Stress test

The first-year plan clears break-even, but the cushion can shrink fast if weekday volume softens or food and labor costs creep up. Here’s the quick math: demand is the main risk, then overhead, then waste and other variable costs.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$108,200	$76,400 cushion	Healthy cushion, but weekday volume still matters.
Revenue shortfall	Revenue drops 15% from the Year 1 run-rate.	$108,200	$48,700 cushion	Weak weekday covers would cut the buffer first.
Fixed-cost increase	Fixed monthly costs rise 10%.	$119,000	$65,600 cushion	Higher overhead bites fast because rent and labor are fixed.
Margin pressure	Variable expenses rise from 19.3% to 24.3%, so contribution margin falls to 75.7%.	$115,300	$69,300 cushion	Seafood waste, fuel, and ice creep can eat the margin.
Combined pressure	Revenue drops 15%, fixed costs rise 10%, and margin falls to 75.7%.	$134,100	$22,800 cushion	If volume, overhead, and waste all slip, the buffer gets thin.

Will this seafood truck hit break-even before you sign the lease, hire staff, and buy inventory?

Founder checklist

Do not lock the lease or major spend until the model shows about $108.2K in monthly Year 1 revenue. Month 3 is the first break-even gate, so pricing, staffing, and inventory all have to hold before fixed costs lock in.

1Demand Proof$108.2K/mo

Verify route stops and weekend pricing can really support about $108.2K in monthly Year 1 revenue, with $120 midweek AOV and $180 weekend AOV doing the heavy lifting.

2Fixed Load$29.8K/mo

Keep fixed non-payroll overhead near $29.8K a month, and do not add a bigger lease or software stack until traffic covers it.

3Contribution Margin81% CM

Check food cost, supplies, and card fees leave about 81% contribution margin, because that is what covers the $87.3K monthly fixed load at the break-even target.

4Prep Capacity$57.5K/mo

Size payroll to the $57.5K monthly Year 1 cap, and confirm the truck can keep up on cold holding, hot holding, ice, and prep without slowing service.

5Cash Cushion$46K

Hold at least the modeled $46K cash floor through Month 10, because that is when cash hits its low point before the ramp starts to pay off.

6Launch BookingsMonth 3

Lock supplier coverage and delay major inventory buys until launch-week demand is booked, because Month 3 is the first break-even gate and unbooked stock burns cash.
