Question

Why is a fixed interest rate almost always better than a variable interest rate

Answer 1

In general, if a lender expects the cash rate to rise, the fixed rate will usually be higher than the variable rate; on the other hand, if the expectation is for the cash rate to fall, the fixed rate will tend to be lower than the current variable rate.

Answer 2

A fixed interest rate will always be the same rate of interest throughout a period of time no matter the amount of borrowed money. A variable interest rate can change over time based on the amount of money borrowed.
