What is an Offset Mortgage?

An offset mortgage links your savings account to your mortgage. The balance in your savings account is used to “offset” the amount you owe on your mortgage, reducing the interest you pay. For example, if you have a £200,000 mortgage and £50,000 in your offset account, you’ll only pay interest on £150,000.

How to Use the Offset Mortgage Calculator

  1. Enter your initial mortgage amount
  2. Input the interest rate
  3. Specify the loan term
  4. Add the current balance in your offset account
  5. Include any regular monthly deposits to your offset account

The calculator will then show you:

  • Total interest saved over the loan term
  • Reduction in loan term (if you maintain regular payments)
  • New monthly payments (if you choose to reduce them)

Benefits of an Offset Mortgage

  1. Lower Interest Payments: You only pay interest on the difference between your mortgage balance and savings.
  2. Flexibility: Access your savings anytime without penalty.
  3. Potential Tax Advantages: Instead of earning taxable interest on savings, you save on mortgage interest.
  4. Faster Repayment: Maintain regular payments to pay off your mortgage earlier.

How the Calculation Works

The calculator uses the following formula to determine your savings:

Interest Saved = (Mortgage Balance - Offset Balance) * Interest Rate

It then computes the cumulative effect over the loan term, accounting for regular deposits to your offset account.

Maximizing Your Offset Mortgage

To get the most out of your offset mortgage:

  • Keep as much money as possible in your offset account
  • Consider directing your salary into the offset account
  • Use credit cards for monthly expenses, paying the balance in full from the offset account
