Cost classification

Break-even works only if fixed overhead and sales-linked costs are separated. Rent and software set the monthly hurdle; driver pay, packaging, spoilage, and marketing CAC change the margin on each order.

Expense	Cost	Break-Even Treatment	Common Mistake
Warehouse Rent	Fixed	Adds $10,000 per month to the overhead hurdle from Month 1 through Month 60.	Spreading rent across orders too early.
Software Licenses (Core Platform)	Fixed	Adds $3,000 per month before any order volume is counted.	Modeling core software as per-order spend.
Salaried Payroll	Semi-fixed	Starts at $46,250 per month in the first year, then rises as full-time equivalent headcount grows.	Treating all payroll as fully variable.
Warehouse Staff	Semi-fixed	Picker-packer labor sits here, scaling from 2.0 full-time equivalents in the first year to 8.0 in Year 5.	Forcing labor to move with every order.
Delivery Driver Per-Order Pay	Variable	Reduces contribution margin by 8.0% of revenue in the first year.	Treating driver pay as all fixed.
Packaging & Supplies	Variable	Reduces contribution margin by 3.0% of revenue in the first year.	Forgetting bags, labels, and order supplies.
Spoilage & Shrinkage	Variable	Reduces contribution margin by 4.0% of revenue in the first year.	Ignoring produce loss and inventory shrink.
Marketing Spend	Semi-variable	Uses a $150,000 first-year budget with a $30 customer acquisition cost, so growth spend ties back to new customers.	Calling CAC-free growth free.

How does break-even move across lean, base, and full-scale grocery plans?

Scenario table

Break-even rises as the model shifts from lean to full scale because fixed costs grow faster than the contribution margin cushion. The business still clears overhead in each case, but the full-scale plan leaves less room for weak order density or slower repeat buying.

These are planning assumptions built from the model inputs, not guaranteed results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean grocery launch	$94,970	$16,620	$78,350	82.5%	$0	Lowest hurdle, so small demand dips can erase the cushion.
Base grocery plan	$130,479	$21,921	$108,558	83.2%	$0	Midpoint case; contribution covers overhead, but the buffer stays modest.
Full-scale grocery rollout	$169,754	$26,821	$142,933	84.2%	$0	Highest fixed load, so break-even depends more on dense routes and fast repeat buying.

What breaks the online grocery break-even plan first?

Stress test

At the current model, break-even sits near $94,970 a month on an 82.5% contribution margin. A 10% sales miss, higher spoilage, or a 10% overhead jump pushes the store negative.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$94,970	$0 gap	No cushion, so any miss hits profit fast.
Revenue shortfall	Monthly revenue falls 10% below plan.	$94,970	$9,497 gap	That miss creates about a $7,835 operating loss.
Fixed-cost increase	Fixed monthly costs rise 10% to $86,185.	$104,467	$9,497 gap	Higher overhead needs more sales just to stand still.
Margin pressure	Spoilage and shrinkage rise from 4.0% to 6.0%.	$97,329	$2,359 gap	Waste pressure adds cost without adding revenue.
Combined pressure	Fixed costs rise 10% and variable expense load rises 5 points.	$111,206	$16,236 gap	Demand softness and margin leak push break-even much higher.

What should the founder verify before signing the warehouse lease and launch build?

Founder checklist

Test demand against the fixed-cost base before you lock in space, staff, and vehicles. The model breaks even in Month 6, but cash bottoms at $173K in Month 7, so weak early orders or high CAC can still sink the plan.

1Order densityMonth 6

Prove one delivery zone can reach break-even by Month 6 before you sign the $10,000 monthly warehouse lease or scale ads past the $30 CAC target, because thin demand makes every stop more expensive.

2Shrink control4.0%

Confirm supplier terms and cold-chain handling before stocking fresh produce, dairy, and frozen items, since Year 1 spoilage and shrinkage are already 4.0% of revenue.

3Unit margin17.5%

Keep packaging at 3.0%, payment fees at 2.5%, and driver pay at 8.0%, because those Year 1 variable costs total 17.5% before other overhead.

4Payroll load$46.25K/mo

Stage hiring before fixed payroll goes above $46,250 per month, since Year 1 salaried labor already covers the founder, operations, technology, customer service, warehouse, and drivers.

5Platform stack$3K/mo

Verify the order system can handle volume before you add the $3,000 monthly license stack, because software is fixed overhead that only pays back if orders flow cleanly.

6Cash floor$173K

Hold at least $173,000 of cash while funding the $680,000 launch build, because the model still hits its low point in Month 7 even with breakeven in Month 6.
