Remortgage Calculator

A Remortgage Calculator is a vital tool for homeowners looking to switch their existing mortgage to a new deal. Remortgaging can help you secure a lower interest rate, reduce monthly payments, release equity, or change the mortgage term. This calculator simplifies the process by allowing you to see potential savings and costs before committing to a new mortgage.

How to Use the Remortgage Calculator

To use the calculator effectively, input the following essential information:

1. Current Mortgage Balance – The remaining amount of your existing mortgage.
2. Current Interest Rate – The rate you’re paying on your current mortgage.
3. New Interest Rate – The proposed rate of the new mortgage deal.
4. Remaining Term – How many years left on your current mortgage.
5. New Term (Optional) – If you want to adjust the duration of the new mortgage.
6. Fees and Costs – Any fees associated with remortgaging (valuation, legal, or arrangement fees).

The calculator then estimates your new monthly payments, total interest savings, and overall cost of remortgaging.

Calculation Logic

The Remortgage Calculator uses the standard mortgage formula to calculate monthly payments:$$\text{Monthly Payment} = \frac{P \times r}{1 – (1 + r)^{-n}}$$Monthly Payment=1−(1+r)−nP×r​

Where:

• $P$P = principal (loan amount)
• $r$r = monthly interest rate (annual rate ÷ 12)
• $n$n = number of monthly payments (term × 12)

By comparing your current mortgage payments with the new projected payments, the calculator shows whether remortgaging is financially beneficial.

Practical Example

Suppose you have an existing mortgage of $250,000 at a 5% interest rate with 20 years remaining. A new deal offers a 4% interest rate.

• Current balance: $250,000
• Current rate: 5%
• New rate: 4%
• Remaining term: 20 years
• Fees: $1,500

Using the Remortgage Calculator, your monthly payment decreases from $1,650 to approximately $1,510. Over the remaining term, you could save around $34,800 in interest, even after accounting for fees.
