Mortgage Calculator: Interest Only vs. Fixed Rate

Which option is right for you: an interest-only or fixed-rate loan?

With an interest-only loan, you can suspend principal payments periodically in order to deal with unexpected reductions in income. A fixed-rate mortgage, on the other hand, gives you the confidence of set monthly payments that will never change over the course of the loan.

Which mortgage is right for me?

If you are a professional who occasionally receives large bonuses or commissions and could use that cash to pay larger lump-sum payments toward the loan with lower monthly payments in between, then you could be an ideal candidate for an interest-only loan. Having the ability to determine the right and achievable amount of equity over the loan term is a great benefit.

However, as with many things, there are risks. If you have an interest-only loan and cannot stick to your financial plan and find you are unable to make the larger lump-sum payments, you could run into trouble and end up overpaying your desired amount of interest.
