What is the break-even point?

The break-even point is the sales volume at which total revenue exactly equals total cost — no profit, no loss. Below it, you lose money on the period; above it, every additional unit contributes its full contribution margin to profit. It's the most common sanity check before launching a product, signing a lease, or hiring.

How do break-even, profit margin, and contribution margin differ?

Break-even is a volume (units or revenue). Profit margin is profit divided by revenue at a given volume. Contribution margin is the per-unit slice of revenue left after variable cost — the portion that "contributes" to covering fixed costs and, beyond break-even, to profit. The first answers "how much do I need to sell?", the second "how profitable was it?", and the third "how much does each sale help?".

What is contribution margin?

Contribution margin is price per unit minus variable cost per unit. If a coffee sells for $4.50 and costs $1.25 in beans, milk, and cup, the contribution margin is $3.25. Each cup contributes $3.25 toward paying off fixed costs; once the rent is covered, those $3.25/cup become profit.

What changes my break-even point?

Three levers, with predictable directions: higher fixed costs raise break-even (more to cover); higher price lowers it (each unit covers more); higher variable cost raises it (each unit covers less). Cutting variable cost and raising price work in the same direction — both expand the contribution margin.

When is break-even misleading?

Break-even assumes a single product, a constant variable cost, and step-free fixed costs over the period. It can mislead when (1) you sell a mix of products with different margins (a weighted average is needed), (2) fixed costs jump in steps as you scale (a second oven, another full-time hire), or (3) variable cost falls with volume (bulk-discount tiers).

How It Works

Formula

\text{Contribution Margin} = \text{Price} - \text{Variable Cost}

\text{Units} = \left\lceil \frac{\text{Fixed Costs}}{\text{Contribution Margin}} \right\rceil

\text{Revenue} = \text{Units} \times \text{Price}

Where

$\text{Fixed Costs}$: Total fixed overhead per period
$\text{Price}$: Selling price per unit
$\text{Variable Cost}$: Variable cost per unit
$\text{Contribution Margin}$: Price minus variable cost — what each unit contributes to fixed costs
$\text{Units}$: Whole units required to break even (ceiling of the ratio)

Subtract variable cost per unit from price to get the contribution margin — the per-unit cash that covers fixed overhead. Divide fixed costs by that margin to get the unit count, then round up because partial units don't ship. Multiplying by price gives the revenue figure.
