Rules & engine

Applicable period: Mathematical XIRR — not a scheme or tax-period rule
Rules last verified: 2026-10-29
Primary source: Excel-compatible XIRR (actual/365 day count)
Engine version: xirr-v1.0.0
Calculation convention: Solves 0 = Σ Cᵢ / (1+r)^((dᵢ−d₀)/365) via Newton with Brent fallback; d₀ = earliest cash-flow date

Known exclusions

Does not imply a unique economic return when multiple mathematical roots exist
Not investment advice; ignores taxes, loads, and fees unless entered as cash flows

Extended Internal Rate of Return (XIRR)

Enter dated cash flows — investments and SIPs as negative amounts, redemptions and current value as positive. Annualized XIRR uses actual day counts on a 365-day basis (Excel-compatible).
