#pricing

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.

Pricing and profitability maths as an API. The margin endpoint solves the relationships between unit cost, selling price, gross margin (a percentage of the price), markup (a percentage of the cost) and profit — give it any two of these and it works out all the rest. Price a product from a target margin, find the true margin of an existing price, convert a markup into a margin (they are not the same — the same price always has a lower margin than markup), or back out a cost from a price and markup. The breakeven endpoint computes how many units, and how much revenue, you need to sell to cover your fixed costs, given a unit price and a variable cost per unit, and returns the contribution margin and contribution-margin ratio. Negative results are reported honestly so a loss-making price is obvious. Everything is computed locally and deterministically, so it is instant and private. Ideal for e-commerce and retail pricing, quoting and sales tooling, finance and FP&A, marketplaces and POS systems, and unit-economics modelling. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is pricing maths; for everyday percentage operations use a percentage API and for loan and interest maths use a finance-calculator API.
