1. Forgetting Time Value of Money
As an advisor, the time value of money must be applied to every calculation, and any calculation that does not take this into account is not accurate. Every dollar has a value that increases over time, or in other words, accrues interest. A common blind spot for financial advisors and clients is forgetting to account for this interest. Time value might seem minor with interest rates as low as they are, but when a cumulative sum is plugged into a calculation it loses all accuracy because the interest value is lost. Interest rates vary depending on the scenario—whether money is being socked away into savings, paid in premiums to an insurance policy, or otherwise—but they are always necessary to include. Regular calculators don’t do a good job of applying the time value of money, which is why interest rates are often overlooked by advisors but Truth Concepts software makes the calculations of interest rates simple and makes the projections you show your client accurate.2. Having Unequal Time Frames
It is all too easy to fall into the trap of comparing mortgage illustration periods with unequal time frames. As with any scientific experiment, when comparing two things you must have only one variable. Often advisors make the mistake of comparing 15 and 30-year mortgages without adjusting the time frames to equal each other—a common mistake to make. When comparing mortgages, you already have a variable, so all other components must be the same to get an accurate comparison. In simple terms, that means these mortgages must be compared over the same time frame—the simplest being a 15-year mortgage over 30 years compared to a 30-year mortgage over 30 years. When advisors compare rates at unequal time frames, the data will be skewed.3. Ignoring Opportunity Cost
Opportunity cost is closely linked to the time value of money, which can be boiled down to this: opportunity cost is the loss of a potential opportunity by taking another one. In typical financial planning, the opportunity cost is not often factored into discussions, or at least not in a way that reveals the whole truth. As with every choice, the possibility of another choice is ruled out. When it comes to investing your money, opportunity cost can be everything—what is the opportunity cost of fees and taxes on the growth of many stock market oriented investments? What is the cost of taking out a loan with the bank rather than borrowing against your whole life’s cash value at the insurance company (or vice versa)? TC software makes it simple to map out multiple options for your client, and Truth Training shows you how through a three-day intensive course.4. Not Understanding How Interest Rates Work
Interest rates are one of the most commonly misunderstood financial concepts, which is how banks are able to make large profits off of seemingly low rates. As a financial advisor it is crucial to understand the true nature of interest rates, so you can best demonstrate the principals to your clients. When assessing the difference between two rates, borrowing at 3% and investing at 9% may not seem too different—only a difference of 6%, right? Unfortunately, that’s the catch; banks and other companies depend on this misconception when the margin of increase is truly a 200% markup. When working with interest rates, converting the rates to dollars can help in understanding their true nature. For example, if your client were to take out a loan of $100,000 at a 4% interest rate and invest that same amount at 5%, you can quickly see that the difference is not 1% but 25%. Learning to understand the truth behind interest rates can keep more money in your client’s pocket instead of the bank’s. Using the TC calculators make it simple to calculate these differences without needing a specific formula.
Figure 1 In this example we have shown 4%, the amount borrowed, as the present value. The future value of 5% is the amount invested. One year is the control. The difference is 25%, or a quarter increase from 4%.

Figure 2 This example serves to show the difference between a 4% rate and a 5% rate on the same amount of money over time. One percent makes quite the difference in this scenario–doesn’t look like 1% now, does it?
