The Annual Percentage Rate (APR) was created with good intentions to make complicated things if not simple, then at least simpler. It even works in many cases! Unfortunately, it also fails in just as many other cases, which sort of devaluates it as a universally reliable tool.

The APR looks a lot like an interest rate, because it is also a percentage. However, it is quite a different parameter. The APR is the sum of the interest rate and a theoretical percentage rate derived from other then the interest, fees associated with a mortgage: points, pre-paid interest, origination fees, attorney and notary fees, closing agent’s document preparation fees, PMI. Third party services, such as appraisals or credit reports, are not included. The purpose of this rate is to summarize all the costs of a mortgage into one number and help a potential borrower make a more informed choice. The borrower should be able to compare mortgages by comparing their APRs. Ideally, a mortgage with the APR of, say, 6.25% should be a better deal than a mortgage with a 7% APR, implying that the latter’s closing costs are higher. The APR is usually higher than the quoted interest rate, but it does not influence your real monthly payments.

It immediately gives one the overall idea of the costs involved. Read the rest of this article »
