Thanks for the explanation. What you are talking about as notional income really is not notional. It is actual, but has been reinvested rather than paid out. Accordingly, it affects the cost of inventory or the purchase price of fixed assets, depending on how you’ve determined you will treat securities held for investment.
As we dive deeper into this topic, and your questions get more specific, you may start to realize that Manager is not optimized for investment accounting. Can it be done? Yes. Is it convenient? Perhaps not. The answers will depend on the types of investments you make, how long you hold them, what your reinvestment practices are, etc.
The first question to consider is whether a double-entry accounting system, centered as it is around recording classical accounting concepts of assets, liabilities, equity, income, and expenses, is the best way to monitor investments. The program’s inventory capabilities are designed primarily to monitor purchase and sale of goods, including calculation of cost of goods sold, profit margins, and such. They are not ideal for monitoring capital gains. Fixed asset capabilities are designed around purchase and depreciation over time of capital assets used in a business, not (hopefully) appreciation of securities and recording of dividend or interest income, especially when reinvested in an account. In the end, you must ask yourself what you are getting for the expenditure of time and energy that you do not already get via reports from your brokerage. It is entirely possible there would be no marginal benefit for you.
Now, I expect other active forum members will weigh in with entirely different perspectives. And those will be equally valid for their situations. Some of them may have quite specific advice. I know there are several forum members who use the program for tracking investments. Let’s see what they have to say.
