Accurately calculate the annualized return of your portfolio. This tool uses the XIRR method to handle irregular deposits and withdrawals.

In the world of investing, understanding how much money you have actually made is often more complicated than it seems. While simple percentages work for fixed deposits or simple loans, the real world of investing involves moving parts: Systematic Investment Plans (SIPs), lump-sum injections during market dips, partial withdrawals for emergencies, and dividend reinvestments.
This is where the concept of Average Return, specifically calculated via XIRR (Extended Internal Rate of Return), becomes indispensable. The Calculatorbudy Average Return Calculator is designed to navigate these complexities, offering you a professional-grade metric to assess your portfolio's performance accurately. Whether you are tracking mutual funds, stock market portfolios, real estate cash flows, or small business returns, understanding your XIRR is the key to making informed financial decisions.
Many novice investors make the mistake of using the Absolute Return formula: ((Current Value - Cost) / Cost) * 100. While this tells you your total profit percentage, it completely ignores the factor of time.
Consider two investors:
If you look only at Absolute Return, both performed equally well. However, logically, Investor A performed significantly better because they achieved the result faster. To compare them fairly, you need an annualized metric. Furthermore, if Investor A added money halfway through the year, the calculation becomes even more difficult. This is why simple ROI is insufficient for modern portfolios.
You will often hear two terms thrown around in finance: CAGR (Compound Annual Growth Rate) and XIRR. Understanding the difference is crucial for using this calculator effectively.
CAGR is the smoothed annual rate of growth of an investment if it had grown at a steady rate each year. It is a theoretical number that describes the rate at which an investment would have grown if it had grown at a steady rate.
(Ending Value / Beginning Value)^(1 / Number of Years) - 1XIRR is the most accurate method for calculating returns when there are multiple transactions at different times. It assigns a "weight" to every cash flow based on the amount and the time it was invested.
The mathematics behind this Average Return Calculator is based on the Net Present Value (NPV) concept. The calculator attempts to find a single discount rate (r) that sets the sum of the present values of all your cash flows to zero.
The formula looks like this:
0 = Σ (Cash Flow_i) / (1 + r)^(d_i / 365)
Where:
Cash Flow_i is the amount of money deposited (negative) or withdrawn (positive).
d_i is the number of days from the first transaction to the date of the i-th transaction.
r is the XIRR (the rate we are solving for).
Because this equation is complex and cannot be solved with simple algebra, our tool uses an iterative algorithm (similar to the "Goal Seek" function in Excel) to find the exact rate that balances your equation. This ensures you get a result precise to two decimal places.
You start a SIP of $500 on the 1st of every month. After 1 year, you check your balance. To calculate your return, you cannot simply sum up your deposits. The first $500 has been working for you for 12 months, while the last $500 has only been invested for 1 month. Using the XIRR calculator, you can input every monthly date and amount to see your true annualized performance.
You invested $10,000 in stocks in January. The market crashed in June, so you added another $5,000. In December, you needed cash and withdrew $2,000. Today, your portfolio is worth $15,000.
This scenario involves irregular timing and bi-directional cash flow (money in and money out). This is the classic use case where XIRR is the only accurate metric.
You bought a rental property for $200,000 (Start Balance). You spent $10,000 on renovations (Deposit/Expense) three months later. You received rental income (Withdrawal/Income) of $1,500 monthly. Finally, you sold the property for $250,000 (End Balance). This calculator can determine the return on your real estate venture by treating expenses as deposits (negative flow) and rental income as withdrawals (positive flow).
Step 1: Set the Baseline. Enter the "Starting Balance Date" and "Starting Balance." If you are starting a new investment from zero, you can set the balance to 0, or enter your very first deposit here. Note that money you invest is typically treated as a negative cash flow in finance, but for ease of use, our calculator handles the logic for you—just enter positive numbers for balances.
Step 2: Add Your Movements. Scroll to the "Transactions" table.
- Select Deposit if you added money to the account.
- Select Withdraw if you took money out (or received a dividend payout).
- Enter the exact Date and Amount. Accuracy in dates is vital for XIRR.
Step 3: Close the Loop. Enter the "Ending Balance Date" (usually today's date) and the "Ending Balance" (current market value of your portfolio).
Step 4: Analyze Results. Hit "Calculate." You will see a percentage.
- Positive XIRR: Your money is growing. Compare this to inflation or a benchmark index (like the S&P 500).
- Negative XIRR: Your portfolio has shrunk in value relative to the capital invested.
This is rare but can happen if you held a large amount of money for a long time with zero growth, and then added a large deposit recently that grew slightly. However, usually, if (End Value + Withdrawals) > (Start Value + Deposits), your absolute return is positive. A negative XIRR usually implies a loss. Check your dates; if you accidentally swapped the start and end years, the math might invert.
XIRR is the Money-Weighted Return (MWRR). It is distinct from the Time-Weighted Return (TWRR), which fund managers often use to eliminate the effect of cash inflows/outflows. As an individual investor, MWRR (XIRR) is more personal to you because it reflects the timing of your specific decisions to buy or sell.
Yes! From a lender's perspective, the loan amount is the "Starting Balance" (money out), the repayments are "Withdrawals" (money in), and any outstanding balance is the "Ending Balance." The resulting XIRR represents the effective interest rate (APR) of the loan.
Yes. The underlying algorithm calculates the difference in days between transactions, so leap years (366 days) are naturally accounted for in the annualized calculation.
If you are analyzing a portfolio that already existed before the period you are checking, you must enter its value at the start date. If you are starting from scratch (e.g., opening a new account), you can set the Start Balance to 0 and enter your initial funding as the first "Deposit" in the transaction list.
While this calculator helps you measure performance, improving it requires strategy.
