Return on Investment Calculator

Calculate your return on investment (ROI), the net gain or loss, and the final-value multiple by comparing what you invested with what it is worth at the end.

Results depend only on the initial investment and final value you enter.

Your investment

Enter the amount initially invested. It must be greater than zero, because ROI divides by it.

Enter the investment's final value, including any proceeds you want to count. Zero is allowed, and a value below the initial investment gives a negative ROI.

Display format only. Amounts are not converted between currencies.

  • Sold: enter the total proceeds received.
  • Not sold: enter the estimated ending value.
  • Count income or distributions only once, and do not double-count what the ending value already includes.
  • Fees, taxes and other costs are not detected; reflect them in your inputs.

How the ROI Formula Works

G = F − I ROI (%) = (G / I) × 100 = ((F − I) / I) × 100 Return Multiple = F / I

I is the initial investment, F is the final investment value or total proceeds, and G is the net gain or loss. The initial investment must be greater than zero so the division is defined.

  1. Enter the original amount invested.
  2. Enter the final value or total proceeds to compare.
  3. Subtract the original investment from the final value.
  4. Divide that gain or loss by the original investment.
  5. Multiply by 100 to express ROI as a percentage.
  6. Divide the final value by the initial investment for the return multiple.
  7. Read the result as a gain, break-even or loss.

A positive ROI means the final value is higher than the initial investment; a negative ROI means it is lower. The calculation does not independently account for taxes, inflation, fees or the timing of cash flows unless those effects are already in the values you enter.

Total ROI is not annualized return. A 30% total ROI over one year and a 30% total ROI over five years are the same total percentage but very different in time, so they do not have the same annual performance. To compare investments held for different periods, use a separate annualized-return calculation.

What Is Return on Investment?

Return on investment is a percentage that compares the net gain or loss on an investment with the amount originally invested. It relates the initial investment to the final value or total proceeds used in the calculation. ROI is only as complete as the numbers entered: it does not automatically account for fees, taxes, inflation or the timing of cash flows.

How to Use the Return on Investment Calculator

  • Initial Investment: the amount originally invested. It must be above zero.
  • Final Investment Value: the ending value or total proceeds. Zero is allowed.
  • Display Currency: symbol and number format only.

How to Calculate ROI

First find the net gain or loss: final value minus initial investment. Then divide it by the initial investment and multiply by 100: ROI = ((F − I) / I) × 100. Taking the gain or loss first gives the amount; dividing by the initial investment turns it into a percentage of what you put in. This matches the formula the calculator runs.

ROI Calculation Example

Suppose you invest $10,000 and the final value is $13,000. Costs and taxes not separately accounted for are excluded, the measurement period is unspecified, and the currency is USD.

G = 13,000 − 10,000 = 3,000 ROI = 3,000 / 10,000 × 100 = 30% Return Multiple = 13,000 / 10,000 = 1.30×

The net gain is $3,000, total ROI is 30% and the return multiple is 1.30×. In this simplified comparison the ending value is 30% higher than the initial investment. Because no period is given, this is not an annualized return.

What Does a Positive ROI Mean?

A positive ROI means the final value you entered is greater than the initial investment. For example, $10,000 growing to $12,000 is a net gain of $2,000 and an ROI of 20%. That is not necessarily after-tax profit or a complete measure of performance.

What Does a Negative ROI Mean?

A negative ROI means the final value is lower than the initial investment. For example, $10,000 falling to $8,000 is a net loss of $2,000 and an ROI of −20%. A final value of zero gives −100% under the simplified model. The calculator keeps the negative sign and never describes a loss as a zero return.

What Is the Difference Between ROI and Annualized Return?

Total ROI measures the overall change from initial investment to final value without regard to how long the investment was held. Annualized return expresses a compounded yearly rate over a stated holding period. Two investments with identical total ROI can have very different annualized returns if their holding periods differ. This calculator does not compute annualized return; see the Annualized Return Calculator below.

What Is the Difference Between ROI and Profit?

Profit or gain is a monetary amount; ROI states that amount as a percentage of the original investment. In the example, $3,000 is the gain and 30% is the ROI. Here, profit means the entered final value minus the initial investment, before any costs or taxes not already reflected in those inputs.

What Does a Return Multiple Mean?

The return multiple compares final value with initial investment. A 1.3× multiple means the final value is 1.3 times the initial amount, which corresponds to a 30% total ROI here. The multiple is a ratio and ROI is a percentage change, so they are not interchangeable labels: a 1.0× multiple means 0% ROI.

What This ROI Calculator Includes and Excludes

It compares one initial investment with one final value or proceeds figure. It does not automatically model:

  • investment fees;
  • taxes;
  • inflation;
  • dividends or distributions not included in the final value entered;
  • recurring deposits;
  • multiple cash flows at different dates;
  • withdrawals during the period;
  • currency conversion;
  • risk or volatility;
  • annualized return;
  • market valuation accuracy.

If an investment has substantial cash flows or costs not reflected in the two inputs, you need a more detailed model.

How to Interpret Your ROI Results

Total ROI is the overall percentage change, net gain or loss is the amount, and the return multiple is the ratio of final to initial value. A gain, a break-even outcome and a loss are different results, and none of them measures risk. A meaningful comparison between investments may also consider holding period, liquidity, volatility, taxes and fees. The calculator does not give individual investment recommendations.

Frequently asked questions

What is a Return on Investment Calculator?

It calculates ROI as the net gain or loss divided by the initial investment, multiplied by 100.

How do I calculate ROI?

ROI = (Final Value − Initial Investment) / Initial Investment × 100. The initial investment must be greater than zero.

What is a good ROI?

There is no universally good ROI. It depends on the type of investment, the measurement period, risk, fees, taxes, liquidity and the benchmark you compare against.

Can ROI be negative?

Yes. ROI is negative when the final value is lower than the initial investment. A final value of zero gives −100% in this simplified model.

What is the difference between ROI and profit?

Profit or loss is a monetary amount. ROI expresses that amount as a percentage of the initial investment.

What is the difference between ROI and annualized return?

Total ROI measures the cumulative return over the whole period. Annualized return accounts for the length of time and states performance as a yearly rate under an appropriate model.

Does ROI include taxes and fees?

Not automatically. This calculator does not account for taxes or fees; they must be reflected in the values you enter or handled in a more detailed calculation.

Can ROI be -100%?

Yes. A final value of zero against a positive initial investment gives −100% ROI under the simplified formula.

Can ROI exceed 100%?

Yes, when the final value is more than twice the initial investment. For example, $10,000 growing to $25,000 gives a 150% total ROI before any costs or taxes not accounted for.

Does this calculator account for how long I held an investment?

No. It calculates total ROI and uses no holding period. To compare investments held for different lengths of time, calculate annualized return separately.
