Break-Even Calculator API

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.

Moldova Inflation & CPI API
Official consumer-price inflation for the Republic of Moldova — sourced live from the National Bureau of Statistics of Moldova via its public PxWeb statbank (tables PRE012600, PRE012200 and PRE012800). The cpi endpoint returns the latest reported month with headline year-on-year inflation and the month-on-month price change. The series endpoint returns the monthly history of year-on-year and month-on-month inflation, parameterised by the number of months. The groups endpoint breaks the latest month down across the major divisions — food goods, non-food goods and services — each with its year-on-year rate, showing where price pressure sits. The core endpoint returns Moldova's core-inflation measures, computed by excluding volatile components such as food, energy and regulated prices, each with year-on-year and month-on-month change — the gauges central banks watch for underlying trend. All figures are published directly by the statistics bureau, not modelled, and refreshed from source behind a short server-side cache with keep-warm. Ideal for macro and emerging-market dashboards, CIS and EU-candidate economics trackers, cost-of-living and monetary-policy tools, and fintech needing a clean structured inflation feed for a market the big aggregators rarely cover at monthly resolution. Live keyless upstream. 5 endpoints.
