Break-even Analysis

Live result on the frontend

The Break-even Analysis calculator shows the sales volume at which a product stops losing money, how much room the business has above that point and how revenue and cost compare on either side of it.

What it calculates

A visitor enters monthly fixed costs, the variable cost and price of one unit and the units they expect to sell. The calculator returns:

• Break-even units and revenue — fixed costs divided by the contribution margin, shown as a whole number of units (rounded up) and as the matching revenue.
• Contribution margin — price minus variable cost, in dollars per unit and as a percentage of the price.
• Margin of safety — how far expected sales can drop, in units, revenue and percent, before profit reaches zero.
• Expected monthly profit — expected units times the unit margin, minus fixed costs; shown as a loss when negative.
• Revenue versus cost chart — paired bars at 0 to 2 times the break-even volume, with costs split into fixed and variable, and a safety gauge with a pin on the expected sales.

How it’s built

Four Number fields feed the PHP Code, which validates the margin (no break-even exists if the price does not exceed the variable cost) and builds every visual as plain HTML: nine bar pairs sized in percent, and a red/green gauge whose split point and pin are computed in PHP.

The PHP returns finished HTML strings (##chart## and ##safety##) that the Exit Layout drops in, next to display strings for the hero and metric cards. The default values give a break-even of 334 units and a $5,280 monthly profit.

Four Number fields: fixed costs, variable cost, price and expected units.

Contribution margin, break-even, margin of safety and the chart and gauge markup.
