Break-even and cost-volume-profit maths as an API, computed locally and deterministically. The breakeven endpoint computes the break-even point of a product — the units you must sell to cover all costs, fixed costs ÷ (price − variable cost) — together with the break-even revenue, the contribution margin per unit and the contribution-margin ratio. The target endpoint computes the units and revenue needed to reach a target profit, (fixed costs + target profit) ÷ contribution margin. The margin-of-safety endpoint takes an actual sales level (in units or revenue) and returns the margin of safety — how far sales can fall before a loss — both in units and as a percentage, plus the profit at that level. Everything is computed locally and deterministically, so it is instant and private. Ideal for business, startup and finance app developers, pricing and product-planning tools, and small-business and accounting dashboards. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is cost-volume-profit analysis; for per-unit margin and markup pricing use a margin API.
