XIRR Calculator - Extended Internal Rate of Return for Irregular Cash Flows
Standard Compound Annual Growth Rate (CAGR) calculations only work for a single, one-time investment. If you invest via SIPs, inject lump sums during market corrections, or withdraw funds randomly, standard math fails. Extended Internal Rate of Return (XIRR) is the institutional standard for measuring the true annualized performance of a portfolio with multiple, irregular cash flows.
XIRR Calculator
Calculate your portfolio's annualized return based on irregular cash flows.
Disclaimer: XIRR is a complex mathematical measure of your annualized return. Ensure that you include your final current portfolio value as a "Sell" transaction at today's date to get an accurate return estimate. The calculations are for illustrative purposes.
How to Use the XIRR Calculator
Because XIRR relies on exact dates and cash flows, data entry must be precise. Follow these steps to diagnose your true portfolio yield:
Step 1: Record Your Initial Investment: Click the calendar icon to enter the exact Date of your very first investment. Set the Type to “Buy (Investment)” and enter the Amount.
Step 2: Add Subsequent Transactions: Click the + Add Transaction button to log every subsequent SIP, lump sum addition, or partial withdrawal.
Select “Buy” for money going into the portfolio.
Select “Sell” for money withdrawn from the portfolio.
Step 3: The Critical Final Step (Current Value): To see your return as of today, you must tell the calculator what the portfolio is currently worth. Add one final transaction with today’s date, set the Type to “Sell”, and enter the total current market value of those assets.
Understanding Your Results: Once all cash flows are entered, the Calculated XIRR instantly reveals your true annualized yield. Note: If you forget to add your current portfolio value as a final “Sell” transaction, the calculator will show a massive negative return (e.g., -99.00%), as it assumes you lost all your money
What is XIRR and Why is It the Ultimate Portfolio Metric?
An XIRR calculator (Extended Internal Rate of Return calculator) is a specialized financial tool built to compute the true annualized rate of return for a series of cash flows occurring at irregular time intervals. In real-world investing, people rarely make a single one-time deposit and walk away. Instead, they invest periodically via SIPs, add lump sums when markets dip, pull cash out for emergencies, and receive dividends. Because every transaction happens on a different date, standard return metrics fail. XIRR normalizes these disjointed data points to give you an accurate, unified annualized performance percentage.
Unlike simple interest, XIRR cannot be solved with a basic algebraic formula. It requires an iterative financial modeling algorithm (like the Newton-Raphson method) to find the exact rate ($r$) that brings the Net Present Value (NPV) of all cash flows to exactly zero.
The XIRR Equation (Solving for NPV = 0):
What the variables mean:
- r = XIRR (The annualized rate of return the algorithm is solving for)
- Ci = The cash flow amount for the i-th transaction. (Investments are negative cash outflows; withdrawals and current portfolio value are positive cash inflows).
- di = The exact date of the i-th transaction
- d1 = The date of the very first investment
Note: Because this equation calculates daily compounding for irregular intervals, the calculator runs hundreds of trial-and-error iterations per second to find the exact rate (r) that balances the equation.
The XIRR Equation (Solving for NPV = 0):
0 = ∑ [ Ci / (1 + r)(di - d1)/365 ]
XIRR vs. CAGR: When to Use Which Calculation Method
Choosing the wrong performance metric can lead to a false understanding of your portfolio’s actual health:
CAGR (Compound Annual Growth Rate): Only tracks a single starting point and a single ending point over flat, unbroken yearly blocks. It works perfectly for a standalone fixed deposit or a single one-time lumpsum investment, but it cannot process any transactions made in between.
XIRR: Tracks every single transaction alongside its exact timestamp. If you run a monthly SIP or frequently buy and sell stocks, XIRR is the only metric that accurately reflects the time-weighted performance of your deployed capital.
Why XIRR is Mandatory for Portfolio Construction
For serious wealth accumulation, tracking your XIRR is a mandatory diagnostic practice.
Accurate Goal Tracking: When building a comprehensive portfolio architecture, you assign a “Required Rate of Return” to your milestones. XIRR is the only metric that accurately confirms whether your mutual funds and stocks are actually hitting those necessary targets after accounting for all your deposits and withdrawals.
Evaluating Mutual Fund Performance: Mutual fund fact sheets display point-to-point CAGR, but your personal return will differ drastically based on when you deployed your capital. XIRR strips away the marketing numbers and reveals your exact, personalized yield.
Asset Allocation Rebalancing: By running an XIRR calculation on individual asset classes (e.g., your debt portfolio vs. your equity portfolio), you can make mathematically sound decisions on where to trim profits and where to allocate future capital.

FAQ
Why does my XIRR show 0.00% or an error value?
XIRR requires both cash inflows (investments) and cash outflows (withdrawals or current valuations) to calculate a rate of return. If you only enter 'Buy' entries without adding a final simulated 'Sell' entry representing your current portfolio market value, the math cannot resolve and will show zero
Why is XIRR used instead of CAGR for mutual fund SIPs?
An SIP spreads investments across different dates, meaning your first installment compounds for a longer duration than your tenth installment. CAGR cannot handle multiple entry points, whereas XIRR weighs each transaction date separately to calculate an accurate annualized return.
Can XIRR be negative?
Yes. If your current portfolio market value or total redemptions are lower than the total amount of capital you invested over the timeline, your net return is negative, and the calculator will display a negative XIRR percentage
How do absolute return and XIRR differ?
Absolute return calculates your simple total gain percentage without factoring in the time it took to earn it. XIRR factors in the exact time elements, showing you what your money earned on an annualized basis, making it easier to compare against benchmarks like the Nifty 50
