Are variable rate loans ever a good idea?
Up to some degree, a higher or lower interest rate means a bit less or a bit more money in your pocket. If the interest rate gets too high, you may be in trouble. So you first look at the situation and ask yourself: At what interest rate would I be in trouble?  If this is a $20,000 student loan, then even a very high rate wouldn't be trouble. It would be unfortunate and unpleasant, but not fatal. For a $800,000 mortgage, that's different. Each percent more is $8,000 a year. Going from 3% to 10% would change the interest from $24,000 to $80,000 a year, which would be fatal for many people.  In a situation where you can afford increasing variable payments without problems you can go for it. If your variable rate would vary over time between 4% and 6% you would still be even. In that situation, go for variable (taking into account where you think interest rates will go in the future). For a mortgage, the security would likely be more important. (On the other hand, if your dad is a multi-millionaire who would help you out, then that big rate increase wouldn't be fatal, and you could go for a variable rate mortgage).  In some countries, you can cancel any loan contract when the interest rate is raised. So raising a variable mortgage interest rate would allow you to look elsewhere without early repayment penalties. Check out if that is the case for you.
