- how to calculate ROI

Return on investment is a very popular measurement because of its simplicity and usefulness. As ROI is calculated in percentage, it's easy to compare the results of many different investments. Consequently, you are able to choose the most beneficial one. If you are involved in trade, you may also need profit margin calculator, which lets you calculate every variable in the sales process. If you want to find your sale price or, inversely, the cost you bear, you should use markup calculator.

The ROI formula is based on two pieces of information - the gain from investment and the cost of investment. The relationship is as follows:

`ROI = (G-C)/C`

Where:

`G`

- gain from investment`C`

- cost of investment

If you have `2 000`

invested and your gain from investment amounts to `5200`

, the equation will be:

`ROI = (5200-2000) / 2000 = 160%`

Although ROI calculator bases its calculation on the same formula, the usage of it is much easier and faster. It's enough only to type invested amount and returned amount to get your estimated ROI. You can also use the return on investment calculator the other way round - plug in the initial principal and the percentage of estimated profit to find out what amount of money you can expect to earn.
