A complete financial-calculation suite: amortizing loan/mortgage schedules, compound-interest and savings projections, net present value (NPV), internal rate of return (IRR) and return on investment (ROI). Deterministic pure math, currency-agnostic, no database and nothing stored - the same input always returns the same numbers.
