Break-Even Calculator

Break-Even Units = Fixed Costs / (Price per Unit - Variable Cost per Unit). Break-Even Revenue = Break-Even Units x Price.

Contribution margin is revenue left after variable costs; it covers fixed costs first and then produces profit. Higher margins mean faster profitability.

There is no break-even — every unit loses money before fixed costs. Raise price, cut variable cost, or rethink the product.

Fixed costs stay the same no matter how many units you make or sell — rent, salaries, insurance, and software subscriptions all cost the same whether you sell ten units or ten thousand. Variable costs scale with each unit produced, so materials, packaging, shipping, and payment processing rise and fall with volume. The distinction matters because break-even math treats them very differently: fixed costs are the lump sum you must cover, while variable costs are subtracted from each sale to find your contribution margin. Misclassifying a cost throws off the whole result, so put one-off recurring overhead in the fixed box and per-sale costs in the variable box. Enter your fixed costs, variable cost per unit, and price above, and the calculator separates them correctly to give you accurate break-even units and revenue.

A contribution margin ratio is the share of every sales dollar left after variable costs, available to cover fixed costs and produce profit. There is no universal target — it varies widely by industry. Software and digital products often run 70% to 90% because each extra sale costs almost nothing, while retail and food businesses may sit at 20% to 40% because materials eat a large slice of each sale. The useful rule is comparative: a higher ratio means you reach break-even on fewer units and absorb slow months more easily, while a thin ratio forces high volume just to cover overhead. If your ratio looks low, you can raise price or trim per-unit cost to improve it. This calculator shows your contribution margin per unit and the ratio as a percentage the moment you enter your numbers.

There are three levers, and break-even responds to all of them. First, cut fixed costs — lower rent, fewer subscriptions, or leaner staffing shrinks the total you must cover, dropping break-even units directly. Second, raise your price, which widens the contribution margin on every unit so each sale chips away at fixed costs faster. Third, reduce variable cost per unit by sourcing cheaper materials, negotiating supplier rates, or cutting packaging and shipping, which also widens the margin. Price and variable cost are usually the most powerful because they compound across every unit sold, while fixed-cost reductions help only up to their fixed amount. The smartest move is to test combinations rather than one change in isolation. Adjust your fixed costs, variable cost, and price above and watch the break-even point recalculate instantly so you can find the mix that works.

Selling at 150% or 200% of break-even means your volume is one and a half or two times the number of units needed to cover all costs. Once you pass break-even, every additional unit contributes its full contribution margin straight to profit, because fixed costs are already paid off at the break-even line. That is why upside scenarios look dramatic: doubling volume does not merely double profit, it can multiply it many times over since there is no profit at all until the line is cleared. The flip side appears at 50% of break-even, where falling short leaves a real loss. This calculator models all four levels — 50%, 100%, 150%, and 200% — showing units, revenue, total costs, and the resulting profit or loss for each. Enter your figures above to see how sharply profit builds as you sell beyond the break-even point.

Yes, the same cost-volume-profit logic works for services — you just redefine the unit. Instead of a physical product, your unit might be one billable hour, one client engagement, one subscription, or one job completed. Set the price to what you charge per unit of service, the variable cost to whatever you spend delivering one more unit such as contractor pay, software seats, or travel, and fixed costs to your standing overhead like office rent and salaried staff. The calculator then tells you how many sessions, projects, or subscribers you need to cover costs and turn a profit. The main caveat is that some service variable costs blur into fixed costs, so classify carefully for an accurate result. Enter your per-unit price, variable cost, and fixed costs above to find the break-even point for your service.
