Weighing your debt basically consists of figuring out what the average rate is you are paying. This works great if you have a primary mortgage plus a HELOC (Home Equity Line of Credit) or a secondary mortgage.
The first step is to add up your debt. For example, you have a $200,000 primary mortgage at 5.875% and a HELOC with a balance of $100,000 with a rate of 7.25%. Your total debt is $300,000.
The next step is to divide your primary mortgage of $200,000 by your total debt of $300,000. This will produce .67, which you will then multiply by your primary mortgage rate of 5.875% which equals 3.94%.
The third step is to do the same process with your HELOC. Divide $100,000 by $300,000 which will produce .33. Multiply .33 by 7.25 and you get 2.39%.
Now, you will add 2.39 plus 3.94 and you get 6.33. So, you are paying an average of 6.33% on both mortgages.
