Which soda blasting expenses stay fixed, and which move with sales?

Cost classification

Break-even is reliable only when steady overhead, job-linked inputs, and step-up crew costs are separated. Here’s the quick math: small classification errors can move the Month 6 break-even target.

Expense	Cost	Break-Even Treatment	Common Mistake
Equipment Storage Yard Rent	Fixed	Include $2,500 per month before launch and through the planning range.	Burying rent in job pricing instead of overhead.
Commercial General Liability Insurance	Fixed	Treat $1,200 per month as required monthly overhead.	Tying the full policy charge to one large job.
Vehicle Insurance and Registration	Semi-fixed	Use $850 per month until another truck changes fleet capacity.	Modeling it as purely job-driven fuel spend.
Sodium Bicarbonate Media	Variable	Apply 14.0% of revenue in the first year, declining to 12.0% by Year 5.	Using a flat dollar amount despite more billable blasting hours.
Fuel and Consumable Parts	Variable	Apply 6.0% of revenue in the first year, declining to 5.0% by Year 5.	Forgetting travel and wear rise with field jobs.
Waste Disposal Fees	Variable	Apply 3.0% of revenue in the first year, declining to 2.0% by Year 5.	Leaving disposal out of margin on messy removal work.
Technician Payroll	Semi-fixed	Model crew pay in steps as technician headcount grows from 2.0 FTE in Year 1.	Assuming labor scales perfectly by the hour.
Marketing	Semi-variable	Use the $15,000 first-year budget and $450 customer acquisition cost together.	Treating ads as fixed while ignoring acquisition volume.

How does break-even shift from lean to full booking levels for a baking soda blasting service?

Scenario table

The lean case is close to break-even, with only a small cushion after fixed costs. As bigger jobs fill the month, contribution rises faster than overhead, so the profit gap opens up fast.

These are planning assumptions, not guarantees, so actual results will move with job mix, routing, and site conditions.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean project mix	$35,100	$9,700	$24,100	72.4%	$1,300	Very close to break-even, with little cushion.
Base blended book	$48,750	$13,406	$24,100	72.5%	$11,244	Comfortable profit, but still watch job mix.
Full industrial-heavy book	$70,200	$19,300	$24,100	72.5%	$26,800	Strong cushion, with break-even well behind you.

What breaks the break-even plan for a baking soda blasting service?

Stress test

The base plan clears break-even, but the cushion gets tight if bookings slow or overhead creeps up. Watch long travel, wasted media, insurance jumps, and hiring before work is booked.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$33,241	$15,509 cushion	Solid cushion at the base run rate.
Revenue shortfall	Monthly revenue falls 20% to $39,000.	$33,241	$5,759 cushion	Slower bookings cut the buffer fast.
Fixed-cost increase	Fixed overhead rises 10% to $26,510 a month.	$36,566	$12,184 cushion	Extra overhead lifts the break-even bar.
Margin pressure	Variable expenses rise to 32.5% of revenue.	$35,704	$13,046 cushion	Fuel, media waste, and repairs squeeze margin.
Combined pressure	Revenue falls 20%, variable expenses rise to 32.5%, and fixed costs rise 10%.	$39,274	$274 gap	This mix flips the month into a small loss.

What should you verify before buying the first truck and blasting rig?

Founder checklist

Don’t buy the truck and second-rig plan until you can show 11 to 12 average projects a month at the Year 1 mix. The model hits break-even in Month 6, but only if fixed costs stay on plan and cash never drops below the $740K floor.

1Demand Proof11-12/mo

Verify you can book at least 11 to 12 average projects each month, because the Year 1 mix only works if the blended project value holds near $2,923.

2Fixed Load$22.9K/mo

Verify the $5.6K in monthly overhead plus about $207K in Year 1 payroll stays funded, since that is the fixed load before any job variable costs.

3Contribution Margin72.5% CM

Verify media, fuel, repairs, and disposal stay near 27.5% of revenue, so each dollar billed still leaves enough to cover the fixed base.

4Crew RampMonth 6

Verify the first truck, compressor, and crew can stay busy before you add the second truck and blasting unit in Month 6.

5Cash Reserve$740K

Verify you can cover the $128K opening capex and the extra $79.5K in Month 6 while still staying above the minimum cash trough.

6Launch Demand$450 CAC

Verify local marketing can win customers at roughly $450 each inside the $15K Year 1 budget before you hire more staff or add equipment.
