Which jam production expenses are fixed, and which move with each jar sold?

Cost classification

Break-even only works if jar-level spend stays below gross profit and fixed overhead stays separate. Treat fruit, jars, labels, labor, freight, and sales fees as unit-driven before testing Month 2 break-even.

Expense	Cost	Break-Even Treatment	Common Mistake
Fruit raw material	Variable	Apply $0.40 to $0.60 per jar based on flavor.	Using one average fruit rate for all recipes.
Glass jar and lid	Variable	Apply $0.20 per jar sold.	Treating packaging as overhead instead of per-sale spend.
Custom label printing	Variable	Apply $0.08 per jar sold.	Leaving labels out of contribution margin.
Direct production labor	Variable	Apply $0.10 to $0.15 per jar based on product.	Mixing jar labor with salaried production payroll.
Commercial kitchen rent	Fixed	Carry $2,500 per month in fixed overhead.	Dividing rent by current jars and calling it variable.
Office supplies and utilities	Semi-variable	Use the $250 monthly base, then review usage as volume rises.	Assuming every utility dollar scales with jar count.
Shipping and logistics	Variable	Apply 4.0% of first-year revenue.	Modeling freight as fixed overhead.
Founder and production salaries	Semi-fixed	Use $152,000 annual first-year payroll, then step up staffing as planned.	Spreading salaries across jars like direct labor.

How does break-even shift from lean to base to full jam production?

Scenario table

As output scales, fixed costs spread over more jars and the break-even gap widens. The lean plan sits closest to the line, while the base and full plans build more cushion if demand stays real.

Planning view only: these figures use model assumptions, so they show direction, not a guarantee.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean jam plan, Year 1	$36,438	$6,993	$16,167	80.8%	$13,278	Near break-even; cushion is about $16.4k.
Base jam plan, Year 3	$82,323	$14,711	$23,283	82.1%	$44,329	Healthy cushion; fixed costs are well covered.
Full jam plan, Year 5	$138,250	$23,043	$25,333	83.3%	$89,874	Strong cushion; add labor only after demand holds.

What breaks the break-even plan for a jam maker?

Stress test

At the current plan, monthly revenue of $36,438 leaves a $16,431 cushion above the $20,007 break-even point. The biggest risks are a 10% sales miss, a $1,000 rise in overhead, and any squeeze in contribution margin from fruit, jars, freight, or labor.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change in sales, overhead, or margin.	$20,007	$16,431 cushion	Healthy cushion, but launch execution still matters.
Revenue shortfall	Monthly revenue falls 10% to $32,794.	$20,007	$12,787 cushion	A 10% miss still clears break-even, but the buffer shrinks fast.
Fixed-cost pressure	Monthly overhead rises by $1,000.	$21,245	$15,193 cushion	Extra overhead lifts the break-even line by $1,238.
Margin pressure	Contribution margin drops 1 point as fruit, jar, label, freight, or utility costs rise.	$20,259	$16,179 cushion	Small cost inflation can move break-even fast.
Combined pressure	Monthly revenue falls 10%, overhead rises $1,000, and contribution margin drops 1 point.	$21,514	$11,280 cushion	This is the tightest case, so price, yield, and sell-through need control.

What should the founder verify before locking in kitchen space and the first big spend?

Founder checklist

Don’t lock kitchen space, equipment, or hiring until demand, pricing, and cash line up with the model. Break-even is early on paper, but the business still needs 47,000 Year 1 jars and a $1.171M minimum cash cushion in Month 2.

1Demand Proof47,000 jars

Verify Year 1 sell-through can clear 47,000 jars across the five lines before you sign a long kitchen lease, because weak demand makes the rent drag show up fast.

2Rent Load$2,500/mo

Check that the monthly kitchen rent fits with the rest of fixed overhead, since the business also carries $3,500 a month before one jar ships.

3Margin Floor$7.62/jar

Price-check the first-year mix inside the $8.50 to $11.50 range and keep contribution near the model, which works out to about $7.62 per jar before fixed costs.

4Supply Lock$17K stock

Secure fruit, sweetener, jar, lid, and label suppliers before buying inventory, because the $10,000 raw stock and $7,000 packaging buy only work if supply is steady.

5Staffing Gate$152K payroll

Hold the Year 1 labor plan at the current three roles until monthly revenue clears the $20,007 break-even point with cushion, so payroll does not outrun sales.

6Cash Cushion$1.171M

Confirm you can fund the $35,000 cooker and filler buy, the $18,000 capping and labeling machine, and the $22,000 launch stack without stressing the Month 2 cash floor.
