What is the difference between a fixed and variable mortgage?

A fixed-rate mortgage keeps the same interest rate for your term, giving you more predictable payments. A variable-rate mortgage is tied to your lender’s prime rate, so it can change during the term. Fixed gives you more certainty, while variable gives you more movement. The right choice depends on your budget, plans, and comfort with change. 

When choosing a mortgage, start with your comfort level

Choose predictability if you need it

Some people sleep better knowing their mortgage rate and payment will stay the same for the term. If that is you, fixed might e the way to go.

Leave room for change if you can

Your down payment matters, but it is not the only cash you will need. Closing costs, moving costs, taxes, and home setup costs can add up quickly.

Think about your actual life

The “best” mortgage rate is not just the lowest number on a page. It is the one that fits your payment, plans, risk comfort, and future decisions.

How fixed mortgages work

A fixed-rate mortgage keeps your interest rate the same for your mortgage term, making payments easier to predict and budget for. Fixed mortgage rates can help protect you from rate increases, but your rate will not automatically drop if rates fall, and penalties may apply if you break your mortgage early.

How variable mortgages work

A variable-rate mortgage can change during your term because it is tied to your lender’s prime rate. If prime moves, your mortgage rate may move too. Your payment may change, or the amount going toward interest may change. Variable mortgage rates can fit if your budget has room and you are comfortable with changes.

What you should consider before choosing a mortgage type

  • How tight is your monthly budget?

    If a higher payment would make things uncomfortable, fixed may feel safer.

  • How long do you plan to stay in the home?

    If you may move before the term ends, ask about penalties, portability, and flexibility.

  • How do you feel when rates change?

    Some people can handle the ups and downs. Some people absolutely hate them. Be honest with yourself.

  • Do you have savings to absorb a change?

    Payment increases due to a variable rate may be easier to manage if you have a cushion you can rely on.

  • Are you considering the full mortgage?

    Rate matters. So do prepayment options, penalties, payment frequency, portability, and advice.

  • Are you buying or renewing?

    First-time buyers may value stability. Renewing homeowners may be open to change.

How payments can change with a variable rate

With a variable-rate mortgage, your payment may change when rates move, depending on how your mortgage is set up. If payments stay the same while rates rise, more may go toward interest and less toward your mortgage balance. Before choosing a variable mortgage rate, ask about payment changes, trigger rates, and switching to a fixed rate.
