Cost classification

Break-even is reliable only if product, shipping, and processing expenses move with each sale while subscriptions and payroll sit in the fixed base. In the first operating year, payroll alone adds $13,125/month before growth hires.

Expense	Cost	Break-Even Treatment	Common Mistake
Raw Materials & Manufacturing	Variable	Apply 10.0% of first-year revenue; this moves with units sold from Month 1 through Month 60.	Treating bulk inventory buys as fixed margin and overstating contribution.
Packaging & Labeling	Variable	Apply 2.0% of first-year revenue; include bottles, labels, inserts, and pack materials.	Leaving labels and containers out of unit economics.
Fulfillment & Shipping Fees	Variable	Apply 6.0% of first-year revenue; model it against paid orders and shipped volume.	Burying shipping in overhead and overstating gross margin.
Payment Processing Fees	Variable	Apply 1.5% of first-year revenue; charge it only to completed paid orders.	Ignoring card fees until cash receipts are reconciled.
E-commerce Platform Subscription	Fixed	Include $500/month in fixed overhead from Month 1 through Month 60.	Spreading the subscription by unit too early.
Website Hosting & Maintenance	Fixed	Include $300/month in fixed overhead across the planning period.	Assuming hosting falls as a percent of sales without testing capacity limits.
Annual Marketing Budget	Semi-variable	Use $150,000 in the first year, and separate planned spend from customer acquisition cost at $35 per new customer.	Blending brand spend and acquisition spend into one flat overhead line.
Payroll	Semi-fixed	Start with $13,125/month in the first year, then step up as new roles begin in later model periods.	Modeling staff as fully variable when hiring happens in jumps.

How does break-even shift from a lean launch to base and full growth for car care products?

Scenario table

Break-even is mostly a fixed-cost problem here. Lean stays in the red, base sits on the line, and full growth only works when higher kit and subscription mix outpaces hiring, marketing, and the $797k cash trough.

Planning assumptions only; actual break-even will move with mix, shipping, and order volume.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$24.3k	$4.7k	$28.2k	80.5%	-$8.6k	Fixed costs outrun margin by about $8.6k.
Base case	$35.0k	$6.8k	$28.2k	80.5%	$0	This is the break-even line, so any slip turns loss.
Full growth case	$48.3k	$7.1k	$40.5k	85.4%	$0.8k	Higher margin helps, but the cushion stays thin.

What pushes this car care products plan past break-even?

Stress test

At the base case, the plan clears break-even, but a 15% sales miss, 10% fixed-cost creep, or a margin slide from 80.5% to 75.0% pushes it into the red. Watch CAC above $35, shipping above 6.0%, discounting, and slow repeat orders.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$35,000	$0 gap	Base case is at break-even.
Revenue shortfall	Revenue falls 15% to $29,750.	$35,000	$5,250 gap	A small demand miss removes the cushion.
Fixed-cost pressure	Fixed costs rise 10% to $30,993.	$38,500	$3,500 gap	Overhead creep pushes break-even above plan.
Margin pressure	Variable expenses rise to 25.0%, so margin drops to 75.0%.	$37,567	$2,567 gap	Freight and discounting weaken contribution.
Combined pressure	Revenue falls 15%, fixed costs rise 10%, and margin drops to 75.0%.	$41,324	$11,574 gap	The plan breaks fast if all three move.

What should a car care products founder verify before committing to bulk inventory, payroll, and paid traffic?

Founder checklist

Don’t lock in inventory, hires, or heavier ads until the model can carry the $797,000 minimum cash need through Month 14 break-even. Month 13 is the cash low point, so launch-month profit is not the test.

1Cash Runway$797K

Confirm cash covers the minimum need and survives the Month 13 trough, or the Month 14 break-even plan slips.

2Paid Demand$35 CAC

Check that the Year 1 marketing budget of $150,000 can buy customers near the $35 CAC, because paid traffic has to work before scale.

3Unit Margin80.5% CM

Verify raw materials, packaging, shipping, and payment fees stay near 19.5% of revenue, which leaves about 80.5% contribution margin (CM) before ads.

4Fixed Base$15.7K/mo

Make sure the monthly fixed base stays around $15,675 before ads and inventory, because any creep in software or admin pushes break-even out.

5Ops RampMonth 13

Stage the content, operations, and support hires after order volume proves out, since the model adds labor in Month 13 when cash is already tight.

6Repeat Lift25% of new

Confirm at least 25.0% of new customers come back, with a 6-month life and 0.4 orders per month, or later subscription demand will not show up on time.
