Creating a household budget using the traditional pen‐and‐paper method has almost become the thing of the past. Today, more and more people are turning to more sophisticated ways to make their budgeting tasks a lot faster and easier. One of the best tools in effectively planning a family budget is a household budget spreadsheet software program, which is widely available on the Internet nowadays.
The first consideration is how clear and accurate the Excel formulas are. The keys here are easy accessibility and logical flow of the formulas. That means they should be either directly coded in the spreadsheet cells or written in an accessible VBA module, open to the user to view and change. Both of these approaches provide the ability to audit and test the formulas without requiring complex actions on the end user‘s part.
First, databases are still tricky for some people to understand. While relational databases can be thought of as tables that have several indexes, this is more than many people want to deal with. Second, the collaboration tools are tough to learn and use. Look at how many people still use Lotus Notes for email and not much else. And since most of us are comfortable with email, using it as the transportation system isn‘t all that taxing. Until the day comes when three people are working on the same spreadsheet and make conflicting changes.
Producing an income and expenditure statement using single entry bookkeeping is little more than making two lists of financial transactions. Those lists being one of sales income received from sales invoices or receipts issued to customers and the other of purchase expenditure being from purchase invoices received from suppliers. To record sales income it would not normally be sufficient to simply add up the total of the invoices as such a summation does not leave an audit trail of the items which have been included. A written list of sales invoices does provide an audit trail.
The fourth component to look for in a real estate investment spreadsheet is the ability to input growth rates. Instead of manually keying in different numbers, say for utility costs or rental rates, simply changing a periodic growth rate is much faster and easier. Most good investment models will allow the user to change the important input factors via growth rate variables. This substantially reduces the time to analyze different scenarios and allows the spreadsheet model to be semi‐automated.
Also, how long is your investment horizon? Is it really that important to you to project out to 30 years or is 3‐5 years sufficient along with a terminal value that represents the expected NPV beyond 5 years? Usually this latter approach works best and looks the most credible to potential investors. There are numerous ways to calculate terminal value including multiples, current market values projected forward, and round guesstimates. Obviously these decisions are affected by your personal preference and the type of investment for which you‘re calculating present value.
