The problem

Founders and FP&A teams need a defensible break-even point, but spreadsheet CVP formulas are easy to mis-key and the result rarely echoes the assumptions behind it.

The local-first solution

This plugin computes the textbook cost-volume-profit identities as exact in-browser arithmetic over the price, costs, target profit, and volume you enter, citing each formula and echoing every input back so a typo cannot silently mis-compute. Nothing is uploaded to any cloud.

What it does

Break-even units and break-even revenue (exact, plus rounded up to a whole unit)

Contribution margin per unit, contribution-margin ratio, and variable-cost ratio

Units and revenue required to reach a target operating profit

Margin of safety in units, revenue, and percent when a current volume is given

Degree of operating leverage at your current volume

Operating profit and total cost at any volume you specify

Honest scope

Every figure is exact closed-form CVP arithmetic on your own inputs, with no fit or lookup. It assumes a single product (or fixed sales mix), linear cost behavior, and pre-tax profit with no inventory timing, taxes, or time value of money - a break-even point is a planning figure under those assumptions, not financial advice or a guarantee of results.

Garrison, Noreen & Brewer (2018). Managerial Accounting, 16th ed., Ch. 5 - Cost-Volume-Profit Relationships: contribution margin = Sales - Variable expenses; units to attain a target profit = (Fixed costs + Target profit) / Unit contribution margin.

Garrison, Noreen & Brewer (2018), Ch. 5 - Degree of operating leverage = Contribution margin / Net operating income; it is the percentage change in operating income for a given percentage change in sales (undefined at the break-even point).
Horngren, Datar & Rajan (2015), Ch. 3 - Contribution margin ratio (contribution margin percentage) = Contribution margin per unit / Selling price = 1 - (Variable cost per unit / Selling price); break-even revenue = Fixed costs / Contribution margin ratio.
