Return on Investment and ROI

Learn about ROI, the return on investments with M1 Finance

What is the definition of return on investment?

The ROI definition is the financial gain or profitability percentage from an investment over a period of time. The return on investment is used in finance to compare the efficiency of different investments. It is also used in business to compare the profitability of such things as equipment and services and in real estate to compare the performance of real estate investments.

This is a measurement of how well an investment performs in relation to its cost, and it is expressed as a ratio. ROI, IRR and ROR are three measurements that let you analyze the performance of an investment over time. The ROI looks at investment’s growth from beginning to end. The internal rate of return or IRR looks at the investment’s annual growth rate. The rate of return or ROR is the net value of discounted cash flows on an investment after inflation.

What does ROI stand for?

ROI stands for the return on investment of the investment that you are analyzing. The calculation is used to determine the profitability of an investment. You compare the gain or loss of an investment with the original amount that you paid to invest in it. It is a measurement that allows you to calculate a return on a stock.

You can also change the formula for different uses. It is used in personal finance and by companies to compare different potential investments. The ROI formula allows you to evaluate the efficiency of various investments over equal periods of time. It can be used to evaluate investments when you are researching a financial plan for retirement or for building wealth. Finally, you can use it to assess your investments when you need to make changes in your portfolio.


You should know key factors when you are determining what investments to include or alter in your portfolio. Staying informed about the market and researching online can help in becoming more financial savvy.

The inflation rate fell to 1.8% earlier this year, which increases the likelihood that the Federal Reserve will cut interest rates this year. Between 1914 and 2019, the average U.S. inflation rate was 3.26%. In the earlier part of  this year, the S&P 500 has had returns of 15.35%, whereas the year before it, it had returns of -6.24%.

How to calculate ROI: The formula

To calculate the return on investment for what you invest in, you simply divide the net profit that you have made by the investment’s cost. You then multiply that amount by 100 to get a percentage as follows:

ROI = (Net Profit/Cost of Investment) x 100

The net profit is equal to the current value of an investment minus its cost:

Net profit = Current value- Cost of investment

To get a more accurate calculation, change the formula by taking into account the taxes that are deducted and any fees that you have paid. For stocks, take into account the transaction costs and dividend payouts for a more precise calculation of the return.

With real estate investments, you should take into account your rental income, taxes, insurance, and maintenance costs when you are calculating the costs. For gains, make sure that you include rental income that you earn for your investment property. For company investments, you should account for the costs and time that went into the investment, including cash payments and employee time and costs.

When you are trying to find different types of investments, compare the ROI of each one. If an investment has a negative ROI or you find other options that have a higher one, forgo the investment. You can use a calculator to calculate the ROI.

You will also want to pay attention to the length of time that an investment was held when comparing its ROI to another investment. For example, John Doe buys $1,000 worth of shares in company A and sells them two years later for $4,000. He calculates the return on investment as follows:

($400/$1,000) x 100 = 40%

John then buys shares from company B for $5,000 and sells them in five years for $7,500. John uses the ROI formula as follows:

($2,500/$5,000) x 100 = 50%

It would appear that John’s investment in company B had a higher return on investment. However, when you take the length of time into account, the result is different. For company A, you can divide the 40% by two years to find that it had an annual return of 20%. By contrast, company B’s return is divided by five years, showing that the annual return was 10%. This means that John’s investment in company A actually performed better.

Investment risk

As risk increases, the potential for higher returns also goes up. Stocks are considered risky when the company that issues them lacks stability. Young investors are able to take more risks on while people who are closer to retirement tend to be averse to risk.

You can minimize the risk in your portfolio by diversifying, but this does not protect against a decline in your portfolio’s value. This involves investing in a variety of different sectors and asset classes over a long period of time. When you invest, you need to stay informed and to monitor your investments’ performance. You should take a long-term view of the market when you monitor them.


The return on investment offers several benefits. It is used for short-term investments because the formula gives you the information that you need with an easier calculation and interpretation. It is also a popular calculation because it can be used across many different fields. Finally, it can help investors to determine the best options for investment purposes according to their needs and abilities to tolerate risk.


There are also some limitations to the ROI. The results can be skewed because they are many. When you look at investments, use the same inputs for greater accuracy. The calculation can be improved by deducting taxes and fees to obtain a more accurate result.

For the net profit of an investment, a company would need to track exactly how much cash went into the project and the time spent by employees working on it. ROI calculation does not account for time and is risky for long-term investments. The longer an investment time horizon, the more difficult it may be to accurately predict earnings, costs, rate of inflation or tax rate.

Rate of Return (ROR)

The rate of return definition is the net loss or net gain of an investment during a specific period of time. You express it by using a percentage of the investment’s initial cost. Gains are the income that you receive from the investment in addition to any capital gains that you realize when you sell it.

The ROR is also referred to as an investment’s basic growth rate. When you take into account inflation and the time value of money inflation, it is the net of the discounted cash flows that you receive on an investment after inflation. The discounted cash flow is a specific type of valuation that can be used to estimate an investment’s value. You can use it to measure growth between two different periods of time.

The formula is used as follows:

ROR = (current value – original value / original value) x 100

It is used to evaluate the growth of our investment, but it does not account for inflation.

For stock rates of return, the prices rise and fall depending on the company’s earnings, the interest rates and the state of the economy. For real estate rates of return, there are many costs, including the interest rates that you pay on a mortgage loan.

To calculate the ROR for a real estate investment, take the sales price after deducting the closing costs, capital gains taxes and improvement costs. From that, subtract the original price after adding in the closing costs, divide by the purchase price and multiply that amount by 100%.

Internal Rate of Return (IRR)

The internal rate of return monitors the performance of an investment over the long term or against market indexes such as the S&P 500. It is also called the economic rate of return or discounted cash flow rate of return.

The internal rate of return looks at the investment’s annual growth rate performance and expected cash flow and is calculated using the following formula:

t = The number of time periods

Ct = The cash inflow during period t

C0 = The total initial costs of the investment

r = The discount rate

​The net present value or NPV accounts for inflation in the value of money over time. The net present value is the difference between the current value of the inflows and the current value of the outflows during a specific time period.

The discount rate is used to determine the present value of future cash flows. It is the interest rate used in discounted cash flow or DCF analysis. It takes into account the time frame of a project when it is used with the ROI. The IRR should be used as one indicator of performance and should be used in conjunction with other types of analyses to determine whether an investment is worthwhile.

An attractive investment will have a higher internal rate of return number. Financial calculators and spreadsheet programs simplify the IRR calculation.

The ROI, IRR and ROR can all help you to determine whether you should invest in a particular investment or instead choose a different one. When you invest through M1 Finance, you can let M1 find the investments that will fit your needs.
