Formula Used
Gross ending wealth = Final value + Income received
Net ending wealth = Final value + Income received - Fees paid - Taxes paid
Net total return = (Net ending wealth - Initial investment) / Initial investment
Annualized return = (Net ending wealth / Initial investment)1 / Years - 1
Real annualized return = ((1 + Annualized return) / (1 + Inflation rate)) - 1
Excess annualized return = Annualized return - Benchmark annual rate
This method is best for lump-sum investments without interim cash flows. Portfolios with many deposits or withdrawals usually need money-weighted return analysis.

Frequently Asked Questions
1. What does annualized return show?
It shows the yearly compounded growth rate that links your starting value to your ending value over the exact holding period. This helps compare investments held for different lengths of time.
2. How is annualized return different from total return?
Total return measures overall gain or loss across the full period. Annualized return converts that outcome into a yearly compounded rate, making comparisons more consistent across different holding periods.
3. Should I include dividends and other income?
Yes. Income distributions are part of investment performance. Enter them in the income field so the result reflects both market value changes and cash received during the holding period.
4. Why do fees and taxes matter here?
Fees and taxes reduce the net wealth you actually keep. Including them gives a more realistic view of investor experience, especially when comparing taxable and low-cost strategies.
5. What is real annualized return?
Real annualized return adjusts the nominal result for inflation. It estimates purchasing-power growth, which is useful when long holding periods make price-level changes more important.
6. Can this calculator handle many deposits and withdrawals?
Not accurately. This tool is designed for a single starting investment with no major interim cash flows. Portfolios with multiple contributions usually need money-weighted or internal-rate-of-return analysis.
7. Why might annualized return show N/A?
If net ending wealth is zero or negative, compounded annualization is not mathematically valid for fractional time exponents. The calculator still shows other useful performance measures in that case.
8. What does excess annualized return mean?
It is the difference between your calculated annualized return and the benchmark annual rate you entered. A positive figure suggests outperformance, while a negative figure suggests underperformance.
