When you decide to put up your own home business, you are most likely prepared to wear all the hats required to run a business. What if you're not? Then, you can always hire others to do what you can't. But what if you suddenly find out that you're out of funds? Don't fret. You can learn to get by while you're business is not yet in such a thumbthumping stage.

One of the most important aspect of business management is seeing whether all the money you've put into it are going down the drains or is actually growing. If you still don't get the drift, you have to know learn how to calculate your return on investment (ROI).

Now don't get all that jittery, if you want to know the profitability of your business, it's important that you know how to come up with the ROI figures.

Since it's hard to be an expert on this field, here is more or less the trouble, er, processes that you have to go through to conquer this one major business aspect:

1. Calculate all the costs associated with an investment.
2. Estimate or calculate your returns.
3. Establish a timeline for costs and returns.
4. Calculate annualized return of investment or APY.
