Mortgage Repayment Calculator

How will interest rates affect your mortgage?

The Bank of England (BOE) base rate, which currently sits at 3%, is the key interest rate in the UK and is important as it influences many other interest rates in the UK, most notably interest rates on savings and mortgages. When the BOE changes the base rate it has significant implications for the UK mortgage market. A rise in interest rates will inevitably result in an equivalent increase in monthly mortgage payments for customers with variable rate mortgages or tracker mortgages. In time, even fixed-rate mortgage customers will see their mortgage payments change, once their fixed-rate period comes to an end.

Step 1 - How to use our free mortgage calculator

To get started enter the original details of your mortgage and then enter the interest rate increase or decrease.

If you are on a variable rate or tracker mortgage:

  1. Enter the original mortgage loan amount borrowed when you took out your current mortgage (i.e 200,000)
  2. Select whether your mortgage type is repayment or interest-only
  3. Enter the number of years remaining on your mortgage (the term) when you took out your existing mortgage
  4. Enter the current mortgage rate that you are paying, in the box titled “current rate” (i.e. 2%)
  5. Input the increase in the interest rate you want to use. For example, if you want to see how a rise of 1% in the mortgage rate (i.e from 2% to 3%) would affect your repayments enter “1”in the box titled “Change”. If you want to see the impact in a drop in interest rates then enter a negative number.
  6. Click “Calculate”

Your results - The calculator will tell you the impact on your monthly mortgage payments. Just make sure that the “Current payment “matches your existing monthly mortgage payments.

If you are on a fixed-rate mortgage:

If you have a fixed-rate mortgage your mortgage repayments won’t immediately change when there is a change in the Bank of England base rate, for example. However, when you come to remortgage at the end of your fixed-rate period the new interest rate you secure is likely to be different. To see the potential change in your monthly mortgage payments when you come off your fixed-rate mortgage deal follow these steps:

  1. Enter the original mortgage loan amount borrowed when you took out your current mortgage (i.e 200,000)
  2. Select whether your mortgage type is repayment or interest-only
  3. Enter the number of years remaining on your mortgage (the term) when you took out your existing mortgage
  4. Enter the current mortgage rate that you are paying in the box titled “current rate” (i.e. 2%)
  5. In the “Change” box enter the difference between the Bank of England base rate, for example, at the time you took out your current fixed-rate mortgage and what the interest rate is predicted to be in the future when you need to remortgage. The chart in our article on remortgaging shows the latest market prediction of where the Bank of England base rate will be over the next five years. If we assume that the BOE base rate at the time you took out your mortgage was 0.1% and that the market anticipates the base rate will reach 4.8% in 2023, when you need to remortgage, you would set the “Change” field as 4.7% (4.8% - 0.1%).
  6. Click “Calculate”

Your results - The calculator will give you a good estimate of your potential new monthly mortgage payments, given changes in mortgage rates. Just make sure that the “Current payment “matches your existing monthly mortgage payment.

The Bank of England’s base rate is currently 3% and market predictions are that mortgage rates could rise over the next two years to be near 5%. So if you currently have a variable rate mortgage or are coming to the end of your fixed-rate mortgage in the next 6 months I would strongly recommend you speak to an independent mortgage adviser as soon as possible to see if you are able to lock-in a better fixed-rate mortgage deal now.
