What is Investment Return Calculator?
The Investment Return Calculator helps you evaluate the profitability of any investment by computing the Return on Investment (ROI), annualized return, and net profit. Whether you are analyzing stocks, real estate, bonds, or any other asset, this calculator takes your purchase price, selling price, holding period, and additional costs (such as brokerage fees, taxes, and maintenance expenses) to give you a comprehensive picture of your investment performance. ROI is calculated as (Net Profit / Total Investment Cost) × 100, where net profit is the selling price minus the purchase price and all additional costs. The annualized return adjusts this total return to a per-year basis using the formula [(1 + ROI)^(1/years) - 1], which accounts for the compounding effect and allows you to compare investments held for different durations on an equal footing. Including additional costs in your calculation is crucial because fees and taxes can significantly erode your actual returns. Many investors overestimate their gains by ignoring transaction costs, capital gains tax, and other expenses. This calculator ensures you see the true net return. Use this tool to compare investment opportunities, evaluate past performance, or set realistic return expectations for future investments.
How to Use
- Enter the purchase price and selling price.
- Enter the holding period (years/months).
- Enter additional costs (fees, taxes) if any.
- Review the ROI, annualized return, and net profit.
Tips & Best Practices
- Always include all costs — brokerage fees, stamp duties, capital gains tax, and maintenance expenses — to get an accurate picture of your true return.
- Use annualized return rather than total ROI when comparing investments with different holding periods for a fair comparison.
- A positive ROI does not always mean a good investment — compare your annualized return against inflation and benchmark indices to assess relative performance.
- Track your investment returns periodically, not just at the time of sale, to identify underperforming assets early.
- Consider the opportunity cost: if your investment returned 3% annually but a savings account offered 4%, the real economic return was negative.

FAQ
What is ROI (Return on Investment)?
ROI is the ratio of net profit to investment cost. It is calculated as (Net Profit / Investment Cost) x 100.
How is annualized return calculated?
Annualized return adjusts the total return to a per-year basis, accounting for the compounding effect.
What is the difference between ROI and annualized return?
ROI is the total return over the entire holding period, while annualized return converts it to a yearly rate. Annualized return is more useful when comparing investments with different holding periods.
Why should I include additional costs in return calculations?
Including fees and taxes gives you the true net profit. Excluding these costs leads to an overestimation of your actual return.
Is my financial data stored?
No, all calculations are performed in your browser and no financial data is sent to or stored on any server.
Can this calculator handle negative returns?
Yes, if the selling price is lower than the purchase price, a negative ROI will be displayed showing the investment loss.
What is a good ROI?
A good ROI depends on the asset class and risk level. For stock markets, an average annual return of 7-10% is historically considered good. For real estate, 5-8% annual returns (including rental income) are typical. Always compare against inflation and risk-free rates.
Why should I use annualized return instead of total ROI?
Total ROI does not account for the time your money was invested. An investment earning 50% over 10 years is very different from one earning 50% in 1 year. Annualized return normalizes performance to a yearly basis for fair comparisons.
How do additional costs affect my return?
Additional costs directly reduce your net profit. For example, if you buy an asset for 10 million won and sell it for 12 million won but pay 500,000 won in fees, your true profit is 1.5 million won (15% ROI), not 2 million won (20%).
Can this calculator handle investments with negative returns?
Yes, if the selling price plus additional costs result in a loss, the calculator will display a negative ROI and net loss amount, helping you understand the magnitude of the investment loss.
Does this calculator account for dividends or rental income?
This calculator focuses on capital gains. To include dividends or rental income, add the total income received to the selling price before entering it, which will give you the total return including both capital gains and income.
What is the difference between nominal and real returns?
Nominal return is the raw percentage gain on your investment. Real return subtracts inflation, showing the actual increase in purchasing power. If your nominal return is 8% and inflation is 3%, your real return is approximately 5%.
