The ROI calculator compares the amount invested with the total amount returned and estimates return on investment, net profit or loss, return multiple and approximate annualized ROI when a duration is entered. This calculator is provided by Hesapstan to help users understand return on investment and approximate annualized ROI more clearly.
What does this ROI calculator calculate?
This calculator compares the investment amount with the total amount returned. It then shows the ROI percentage, net profit or loss, total returned amount, original investment, return multiple and, when a duration is provided, an approximate annualized ROI.
- Calculates net profit or loss from the entered values.
- Shows ROI as a percentage of the original investment.
- Shows how many times the investment was returned as a return multiple.
- Classifies the result as profit, loss or break-even.
- Annualizes the return approximately when duration is entered.
This is a simplified ROI calculation. It does not automatically include taxes, commissions, inflation, risk, currency effects, separate dividends or multiple cash flows.
What is ROI?
ROI stands for Return on Investment. It measures how much profit or loss an investment generated compared with the amount originally invested.
For example, if you invest 100,000 TL and receive 125,000 TL in total, the net profit is 25,000 TL and the ROI is 25%. If the returned amount is lower than the investment amount, ROI becomes negative.
How is ROI calculated?
The formula used here is: ROI = (total returned amount − investment amount) / investment amount × 100. The returned amount should represent the total value that came back to you from the investment.
For a more realistic ROI, use a returned amount after direct selling costs, transaction fees or taxes if those costs are known. Otherwise the ROI may look better than the real outcome.
Net profit, ROI and return multiple
Net profit is the difference between the returned amount and the investment amount. ROI converts that difference into a percentage of the investment. Return multiple shows how many times the investment amount was returned.
- Net profit: the amount gained or lost in currency terms.
- ROI percentage: profit or loss relative to the investment amount.
- Return multiple: returned amount divided by investment amount.
- Status: profit, loss or break-even summary.
What does approximate annualized ROI mean?
When a duration is entered, the calculator converts the total return into an approximate annual rate. This helps compare investments with different holding periods.
A 20% total ROI over one year is very different from a 20% total ROI over five years. Annualizing the return makes the time dimension more visible.
Annualized ROI here is a simplified estimate. If there are multiple cash flows, additional contributions, withdrawals or periodic income, a method such as IRR may be more appropriate.
When is ROI useful?
ROI is useful for a first-level view of whether an investment gained or lost money. It is especially practical for simple cases with one initial investment and one final returned value.
- Checking the basic profitability of a small project.
- Measuring the result of buying and selling an asset.
- Comparing simple investment ideas at an early stage.
- Separating absolute profit from percentage return.
When is ROI not enough?
ROI does not measure every important part of an investment. Two investments may have the same ROI but very different risk, duration, liquidity, tax treatment and cash-flow timing.
- Use IRR when there are multiple cash inflows and outflows.
- Use NPV when the present value of future cash flows matters.
- Use payback period when recovery time is important.
- Compare with inflation if you need real return.
- Assess risk and volatility separately.
ROI vs IRR
ROI is a simple ratio based on investment amount and total returned amount. IRR is a more advanced method that considers the timing of cash flows.
If money is added or withdrawn at different dates, or if the investment generates periodic income, ROI alone can hide important details. In such cases, IRR or a full cash-flow analysis may be needed.
ROI, inflation and real return
This calculator shows nominal ROI. It does not automatically subtract inflation. In high-inflation environments, a positive nominal ROI may still be weak in terms of purchasing power.
For example, if an investment earns 30% but prices rise 40% over the same period, the purchasing-power result may be weaker than the nominal ROI suggests.
Taxes, fees and costs
The calculator does not ask for taxes or commissions separately. If you know those costs, use a returned amount after relevant costs for a more realistic ROI.
This calculator does not provide investment advice. It only calculates a mathematical return ratio from the values entered.
Frequently Asked Questions
How do you calculate ROI?
ROI is calculated by subtracting the investment amount from the total returned amount, dividing the result by the investment amount and multiplying by 100.
Is ROI the same as net profit?
No. Net profit is an amount of money; ROI is that profit or loss expressed as a percentage of the investment amount.
Is ROI always annual?
No. ROI is total return. If duration is entered, this calculator also estimates approximate annualized ROI.
Does this replace IRR?
No. IRR is more appropriate when there are multiple cash flows at different dates.
Are taxes, fees and inflation included?
No. Taxes, fees, inflation, risk and other costs are not automatically included.
