Average Return Calculator
Calculate average investment returns for cash flow scenarios (XIRR / Money-Weighted Rate of Return) and multi-period holding durations (Geometric Mean / CAGR).
Average Return Calculator
The Average Return Calculator can calculate an average return for two different scenarios. The first is based on cash flows, and the second calculates a cumulative and average return of multiple investment returns with different holding periods.
• Cash Flow (XIRR): Calculate the annualized money-weighted return considering the exact calendar dates of deposits and withdrawals.
• Multi-Period (CAGR): Compute cumulative geometric mean return across distinct holding periods of varying lengths.
Average Return Based on Cash Flow
This calculator estimates the average annual return of an entire account based on the starting and ending balances as well as the dates and amounts of deposits or withdrawals.

Cumulative Cash Inflow vs. Portfolio Balance
Understanding Average Investment Returns: XIRR vs. CAGR
Evaluating the performance of an investment portfolio requires choosing the appropriate rate of return metric. Because investors frequently deposit and withdraw money at irregular dates, simple arithmetic averages can produce misleading results.
Money-Weighted Return (XIRR)
XIRR calculates the exact annualized internal rate of return for portfolios with irregular cash inflows and outflows. It reflects the personal investor experience by weighting returns based on when more or less money was in the market.
Geometric Mean (CAGR)
The Compound Annual Growth Rate measures the smoothed annual rate at which an investment grows over multiple holding periods, accounting for the compounding effect of gains and losses.
Arithmetic vs. Geometric
A simple arithmetic average overestimates long-term compound growth. For instance, a +50% gain followed by a -50% loss yields an arithmetic mean of 0%, but an actual cumulative loss of -25%.

How to Use the Average Return Calculator
- 1 Select your calculation scenario: "Cash Flow (XIRR)" for irregular deposits/withdrawals, or "Multi-Period Return" for consecutive holding periods.
- 2 For Cash Flow: enter your starting balance & date, ending portfolio balance & date, and add any intermediate deposit/withdrawal transactions.
- 3 For Multi-Period: enter the return percentage and holding duration (years and months) for each consecutive period.
- 4 Click "Calculate" to view the annualized average return (XIRR / CAGR), total cumulative gain, net invested capital, and growth chart.
Average Return Calculator — Frequently Asked Questions
Q1 What is the difference between Money-Weighted Return (XIRR) and Time-Weighted Return (TWR)? ▾
Money-Weighted Return (XIRR) measures the personal rate of return by accounting for the timing and size of cash deposits and withdrawals. Time-Weighted Return (TWR / Geometric Mean) isolates pure portfolio investment performance by neutralizing the distortionary effect of external cash flows.
Q2 Why is Geometric Mean (CAGR) better than Arithmetic Average for investment returns? ▾
Arithmetic average fails to account for compounding and volatility drag. For example, a +50% gain followed by a -50% loss yields an arithmetic average of 0%, but the actual cumulative investor capital suffers a 25% net loss.
Q3 What is an XIRR calculation and when is it used? ▾
XIRR (Extended Internal Rate of Return) computes the annualized rate of return for a series of irregular cash flows occurring at specific calendar dates. It is the gold standard for evaluating real-world brokerage and retirement accounts.
Q4 How do deposits and withdrawals affect my money-weighted rate of return? ▾
Depositing large sums right before a market rally substantially boosts your money-weighted return because more capital participates in the uptrend. Conversely, depositing right before a market dip drags down money-weighted performance.
Q5 How is cumulative total return compounded across multiple holding periods? ▾
Cumulative total return is calculated by chaining period multipliers: (1 + R_cum) = (1 + R_1) × (1 + R_2) × ... × (1 + R_n). The annualized CAGR is then derived using the total combined holding time in years.
