Discounted-cash-flow investment-appraisal maths as an API, computed locally and deterministically. The npv endpoint computes the net present value of a project from an upfront outlay, a series of future net cash flows and a discount rate, NPV = −initial + Σ CFₜ/(1+r)ᵗ, and reports the present value of the inflows, the profitability index and a plain accept-or-reject decision. The irr endpoint solves the internal rate of return — the discount rate that makes the NPV zero — by robust bisection over the cash flows, the figure you compare against a hurdle rate. The payback endpoint computes both the simple payback period, when the cumulative cash flow first recovers the outlay, and the discounted payback period, which discounts each flow first. Cash flows are passed as a comma-separated list, one per period. Everything is computed locally and deterministically, so it is instant and private. Ideal for finance, corporate, fintech and project-management app developers, capital-budgeting and feasibility tools, and finance education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is capital budgeting; for loan amortization use a loan API and for CAGR and real returns an investment API.

API de Calculadora de Inversiones
Matemáticas de inversión y presupuesto de capital como API. El endpoint npv calcula el valor presente neto de una serie de flujos de efectivo a una tasa de descuento (el primer flujo suele ser la inversión inicial negativa). El endpoint irr encuentra la tasa interna de retorno —la tasa de descuento a la cual el valor presente neto es cero— mediante una búsqueda robusta por intervalos. El endpoint annuity resuelve una anualidad nivelada (ordinaria): dados la tasa, el número de períodos y cualquiera de los valores de pago, valor presente o valor futuro, devuelve los otros dos. El endpoint depreciation construye un cronograma completo año por año mediante los métodos de línea recta, saldo decreciente (cualquier factor, incluyendo doble saldo decreciente) o suma de dígitos de los años, sin depreciar por debajo del valor de rescate. Las tasas pueden ingresarse como porcentaje o fracción. Todo se calcula local y determinísticamente, por lo que es instantáneo y privado. Ideal para análisis de inversiones y presupuesto de capital, herramientas de contabilidad y finanzas corporativas, planificación empresarial y educación financiera. Cálculo local puro —sin clave, sin servicio de terceros, instantáneo. En vivo, nada se almacena. 5 endpoints. Esto son matemáticas de inversión y presupuesto de capital; para préstamos, hipotecas e interés compuesto, use una API de calculadora financiera.

CAGR & Returns API
Investment growth and return maths as an API, computed locally and deterministically. The cagr endpoint computes the compound annual growth rate, CAGR = (end/begin)^(1/years) − 1 — the single smoothed annual rate that compounds a starting value into an ending value — together with the total return and the growth multiple, so €1,000 growing to €2,000 over five years works out to about 14.87 %/yr. The future-value endpoint compounds a single lump sum, FV = PV·(1+r)^n, and the present-value endpoint discounts a future lump sum back to today, PV = FV/(1+r)^n. The annualize endpoint converts a total holding-period return over a span of years into an equivalent annual rate, and back the other way. The doubling-time endpoint gives the exact time for money to double, ln2/ln(1+r), alongside the Rule-of-72, Rule-of-70 and Rule-of-69.3 quick estimates — at 8 % money doubles in about nine years. Rates are decimals (0.07 = 7 %) except the doubling endpoint which takes a percentage. Everything is computed locally and deterministically, so it is instant and private. Ideal for fintech, investing, portfolio, robo-advisor, personal-finance and finance-education app developers, return-and-growth calculators, and dashboards. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 5 endpoints. These are single-sum growth and return metrics; for level-payment loans use a loan API and for regular-deposit savings a savings API.

API de Calculadora de Inflación
Matemáticas de economía de inflación como API, calculadas local y determinísticamente. El endpoint adjust expresa un valor a lo largo del tiempo de dos maneras: mediante una tasa de inflación anual durante un número de años, V = monto·(1+r)^años, o mediante una relación de índices de precios al consumidor, V = monto·IPC_fin/IPC_inicio, de modo que un precio antiguo pueda expresarse en dinero actual, con la inflación total del período. El endpoint real-rate calcula la tasa de interés o inversión real (ajustada por inflación) a partir de una tasa nominal y una tasa de inflación utilizando la ecuación de Fisher, 1 + real = (1 + nominal)/(1 + inflación), junto con la aproximación aproximada de nominal menos inflación. El endpoint purchasing-power muestra cómo la inflación erosiona el dinero con el tiempo: el poder adquisitivo futuro de una cantidad actual, monto/(1+r)^años, el valor perdido y la cantidad mayor necesaria para mantener el mismo poder adquisitivo. Las tasas pueden ingresarse como porcentaje o fracción y los montos en cualquier moneda. Todo se calcula local y determinísticamente, por lo que es instantáneo y privado. Ideal para desarrolladores de aplicaciones de finanzas personales, presupuestos, salarios, planificación de jubilación y economía, herramientas de costo de vida y rendimiento real, y educación financiera. Cálculo local puro: sin clave, sin servicio de terceros, instantáneo. En vivo, nada almacenado. 3 endpoints. Esto es ajuste por inflación; para pagos de préstamos use una API de préstamos y para crecimiento de inversiones una API de inversiones.

Bond Pricing API
Fixed-income bond maths as an API, computed locally and deterministically. The price endpoint computes a bond's price from its face value, coupon rate, yield to maturity, years to maturity and coupon frequency — Price = Σ coupon/(1+y)ᵗ + face/(1+y)ⁿ with y the periodic yield — and reports the clean price as a percent of par, the annual coupon, the current yield and whether the bond trades at a premium, discount or par. The yield endpoint inverts this, solving for the yield to maturity that matches a given market price by bisection, with the current yield. The duration endpoint computes the Macaulay duration (the cash-flow-weighted average time), the modified duration (which approximates the percent price change per 1 % yield move), the convexity and the DV01 (the price change per basis point). A zero-coupon bond is just coupon rate 0. Everything is computed locally and deterministically, so it is instant and private. Ideal for fintech, fixed-income, treasury and portfolio app developers, bond-analytics and risk tools, and finance education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is bond analytics; for option pricing use an options API and for NPV and IRR an NPV API.
