XIRR Calculator
Calculate Extended Internal Rate of Return online. Compute annualized returns for irregular cash flows with zero server uploads.
What is the XIRR Calculator?
The ToolboxDock XIRR Calculator is a free, 100% browser-based financial utility that calculates money metrics directly in client-side RAM with zero server transfers. It provides instant mathematical modeling for loans, investments, taxes, and amortization schedules while ensuring complete confidentiality of your sensitive financial data.
Evaluating investment performance with multiple, irregular transaction dates requires Extended Internal Rate of Return (XIRR). Standard CAGR assumes single lump-sum investments, whereas XIRR accounts for exact transaction dates.
Our online XIRR calculator computes annualized returns for systematic investment plans (SIPs), recurring deposits, and multi-stage portfolio cash flows with 100% client-side execution.
Financial Calculation Inputs
- Supported Inputs: Principal balances, interest rates, compounding schedules, and tenures.
- Precision Model: High-precision IEEE-754 floating-point arithmetic with decimal rounding.
- Data Privacy: Zero cloud logs. Figures are calculated locally in your browser memory.
Output & Schedule Breakdown
- Visual Analytics: Month-by-month schedules, dynamic charts, and cash flow summaries.
- Currency Support: Multi-currency symbol formatting (USD, EUR, GBP, INR, JPY, CAD, AUD).
- Access Guarantee: 100% unlocked with zero limits, subscriptions, or forced account creation.

XIRR Mathematical Formula
Solves for discount rate r such that the sum of discounted cash flows equals zero across exact transaction dates d_i.
Core XIRR Calculator Inputs & Terminology
Extended Internal Rate of Return is the annual rate of growth that equates the net present value of irregular cash flows to zero.
Negative values represent cash invested (outflows), while positive values represent cash received (inflows or current value).
CAGR measures point-to-point lump-sum growth, whereas XIRR measures annualized growth across recurring or irregular investments.
