Fixed vs variable: what if?

Compare fixing your rate for a few years with staying variable, using your own guess for where rates go after the fixed period.

Your own guess. Used for both options.

What these numbers mean
  • The big number is the difference in total interest between fixing first (A) and staying variable (B), on your rate guesses.
  • Repayment for the fixed years shows each option at its starting rate. Balance after shows what is still owed when the fixed period ends.
  • Repayment after uses the rate you guessed for the rest of the term.
  • Nobody knows future rates, and break costs can apply to fixed loans.

Good to know

  • Both options switch to the rate you expect when the fixed period ends, and the balance left is spread over the rest of the term.
  • Rates can move any way, at any time. Your guess is only a guess.
  • Break costs can apply if you pay off or change a fixed loan early. Fees are not included.
  • This is a guide only, not a quote, an offer of finance, a borrowing limit or financial, legal or tax advice.
