Return On Investment Formula

Some money expert says, the smartest ROI formula is the rule of 72, which will also be discussed in this article. Just determine the invested years to 72 and the answer will be the required interest that your investment should earn.

Example, if you want to double your money in 5 years your investment should earn at least 14.4% per year. Your money will double due to compound interest.

Reverse the formula, if you are investing your money in an investment vehicle that earn 8% annually, how many years to wait to double your invested capital? (Formula: 8/72= 11years).

How to measure ROI?
An investor can measure ROI by analyzing the interests earn per annum or even in per month. Measuring the return of investment is very important to know when and where to invest your money.

Return On Investment Example

Some example, if you invest $1,000,000 in mutual fund bond fund type, and earn 5% per annum within 8 years, the return of invested capital is $477,455.44

If you invest $1,000,000 in government securities promising to earn 4.5% per year for 10 years. The return of investment is $552,969.42

Another example in business ROI
Operating Expense: $150,000
Total Assets Beginning of year: $380,000
Total Assets End of Year: $420,000
Average Investment in Assets: $400,000
Return on Total Assets: 37.5%

ROI Formula: To get the average investment asset, just add total assets beginning and end of year then divide by 2. That’s how we get $400,000. To get the possible ROI, just divide operating expense by the average investment in assets. That’s how we get 37.5%

The higher the risk the higher the return of your investment. Risks such as time frame or the number of years that your money is invested, world economic crisis, calamities, political issues and among other things that consider as “risk” in investing.

You can use rate of return calculator in other websites so that it is easy for you to analyze if you invest your money or not. Also, the rate of return doesn’t guarantee the best possible return of investment. Past performance of an investment vehicle doesn’t guarantee a good return on your investments.

Investments type that has guaranteed return investments are few, so be careful. In investing, there’s no such thing as “guarantee”. Some say, bonds are good type of investment but still, there is a risk involved. If there is a risk, there is no guarantee.

Do not be lured to quick return investment schemes, some example of an exciting investments are as follows;
Double your money in 2 days, possible high return on investment in few weeks. Return in invested capital will be given right away, duh? Just be smart enough.

Ask the financial expert or the registered financial planner about investing before you decide. They will help and guide you, unwise investing decision can cost you a lot. So be very careful and make your own research and investigation about the companies that offers financial products such as mutual funds or stock brokering.
