Break-Even Analysis for CPG Products: How Many Units Do You Need?

Every CPG founder has been asked the question: “When do you break even?” It comes up in investor meetings, in board conversations, and in the quiet moments when you are staring at your bank balance wondering if the numbers will ever work. The frustrating part is that most founders answer this question using gut feeling or rough math that ignores half the costs involved in actually selling a physical product.

A proper break-even analysis for a CPG brand is not a single number. It varies by SKU, by channel, and by how you allocate your fixed costs. Get it right and you have a roadmap for when and how the business becomes self-sustaining. Get it wrong and you scale into a loss that gets deeper with every unit sold.

The textbook break-even formula is simple: divide your fixed costs by your contribution margin per unit. The result is the number of units you need to sell to cover all fixed expenses.

Simple enough. But the accuracy of this number depends entirely on whether your contribution margin per unit is calculated correctly. Most CPG founders use gross margin per unit instead of contribution margin — and the difference can double your actual break-even point.

To calculate a meaningful break-even, you need to build up the full variable cost per unit. This includes everything that scales directly with each unit sold.

The gross margin is $7.00 per unit, but the contribution margin is only $3.50 once you account for trade spend, freight, chargebacks, and distribution. Using the right number completely changes the break-even calculation.

Because contribution margin varies dramatically by channel, your break-even point is not a single number. A unit sold on Shopify contributes differently than a unit sold through a distributor into grocery. Running the analysis by channel reveals which channels help you break even and which ones work against you.

The channel with the lowest contribution margin per unit requires nearly three times the volume to break even compared to DTC. This does not mean you should avoid distributed retail — it means you need to understand the volume commitments each channel requires before expansion is financially viable.

The other half of the break-even equation is fixed costs, and most founders undercount them. Your fixed cost base is not just rent and salaries. It includes every expense that does not vary with each additional unit sold.

Commonly Overlooked Fixed Costs

Break-even is not just a number for your pitch deck. It is a decision-making tool that should inform how you allocate resources.

New Product Launches

Before launching a new SKU, calculate its contribution margin and estimate the incremental volume you can realistically achieve. If the SKU does not reach break-even contribution within 12 to 18 months — accounting for any incremental fixed costs it adds — it may not be worth the launch. Every underperforming SKU raises the break-even threshold for the rest of the portfolio.

Channel Expansion

Entering a new retail channel often comes with upfront costs: slotting fees, introductory trade spend, broker commissions, and new packaging requirements. Model the break-even for the channel specifically. How many months of expected velocity does it take to recover the launch investment and start contributing positively?

Pricing Decisions

When considering a price increase, model the impact on break-even volume. A 10% price increase on a $12 wholesale price adds $1.20 to contribution margin per unit. If fixed costs are $29,000, that drops break-even from 8,286 to 6,170 units — a 25% reduction. Even if you lose some volume from the price increase, you may come out ahead.

Static break-even is useful for planning, but the most actionable version is a rolling break-even tracker. Each month, calculate your actual blended contribution margin per unit (based on real channel mix and real costs, not projections) and divide into your actual fixed cost base. This gives you a monthly break-even target that reflects how your business is actually operating.

Track the gap between your actual unit sales and your break-even threshold. When that gap is narrowing, you are moving in the right direction. When it is widening, something has changed — fixed costs crept up, contribution margins compressed, or channel mix shifted — and you need to dig in before the trend becomes a crisis.
