<p>To Chocoholic --
It is true that the proportion of payments going toward interest is always higher in the early years of an amortized loan, but it is NOT true that the figure is always 75% -- the percentage depends on the length of the loan and the interest rate. The longer the loan term and higher the interest rate, the higher the percentage going to interest. So with a 30 year loan for $200K at 7% interest, the first payments have 87% of the money going toward interest; if the interest rate was 5%, the percentage would be only 77%; if it was a 15 year note at 5% interest, the percentage for the first payment is only 52% -- which is the same as it would be in year 16 of the 30-year loan with the same interest rate. The issue isn't how close you are to the beginning of the loan; it is how close you are to the end. </p>
<p>So, lets take a hypothetical 30-year, $200,000 loan at 7% - the first payment breaks down as follows:
Principal: $ 163.94 Interest: $ 1166.67 - total monthly payment: $1330.60</p>
<p>At the end of the 15th year, the balance owed on the loan is $ 147,570.68. The homeowner has paid out $187,546.61 in interest; if that loan is maintained, the homeowner will pay out an additional $91,471.19
in interest over the life of the loan.</p>
<p>In the first month of year #16 (when there is 15 years left), the breakdown of the payment will be:
Principal: $ 467.05 Interest: $ 863.55 (65% of the payment)</p>
<p>Lets say that the homoeowner now decides to refinance to get a lower interest rate - with closing costs, the new loan is for $150,000. The homeowner chooses a 15 year note, with a 5% interest rate. With the refinance, the monthly payment goes down to $1,186.19</p>
<p>For the first payment - the breakdown between principal and interst is as follows:
Principal: $ 561.19 Interest: $ 625.00 (52%)</p>
<p>As you can see, with the refinance for the 15 year note, the homeowner is now paying almost $100 MORE toward principal with the first payment - AND the monthly payment is $144 less - more money in the homeowners pocket. </p>
<p>The balance of interest that would be paid over the life of the new loan is $63,514.28 - a savings in interest of almost $28,000 over the remaining 15 years. If you add in the value of the lower payments - a net out-of-pocket savings of almost $26,000 -- the refinance saves the homeowner $54,000 over the life of the loan. </p>
<hr>
<p>This really isn't rocket science. Any loan with lower interest and equivalent or shorter term is going to save money over the higher interest loan - the problem is simply that a lot of people opt to refinance in a way that extends the loan term. </p>
<p>Obviously, it gets more complicated because people rarely refinance exactly in the middle of the loan term -- so the typical homeowner with a 30 year mortgage, 7 years into their first loan, may have a harder question when contemplating whether to opt for a 30 year or 15 year mortgage on a refinance. Plus there are other issues depending on the age and family circumstances of the homeowner -- and tax bracket. </p>
<p>But again -- all the homeowner really has to do is print out the amortization schedule for the current note compared with the new note - and do a little bit of math to figure out where the savings come in. </p>
<p>I do agree with everyone who says that we should all be looking at the numbers carefully -- you particularly want to look at the numbers that show the total amount you will pay over the life of the loan. I just don't believe that it is all that complex to figure out. The people here who are involved in finance probably do have clients who don't do the math in the first place - the people who want to run out and refinance every couple of years to get the advantage of every drop in rates - but I'm hoping that those of us who are trying to juggle college tuition and our retirement plans in the mix are going to take the time to look at the big picture.</p>
