Breaking Fixed Mortgage Calculator

Determining when your variable mortgage becomes cheaper than your fixed rate is crucial for making informed financial decisions. Our breaking fixed mortgage calculator helps you find the exact break-even point by comparing the costs of both mortgage types over time.

What is a Breaking Fixed Mortgage?

A breaking fixed mortgage is a type of mortgage where the fixed rate period can be ended early, typically after a certain number of years. This allows borrowers to switch to a variable rate mortgage if it becomes more favorable.

The "break point" is the time when the cumulative interest paid on the variable rate mortgage equals the cumulative interest paid on the fixed rate mortgage. After this point, the variable rate becomes cheaper.

Breaking fixed mortgages are popular among borrowers who want the security of a fixed rate for a certain period but also benefit from potential lower variable rates in the future.

How to Calculate Your Break Point

Calculating your break point involves comparing the interest costs of both mortgage types over time. Here's a simplified formula:

Break Point (in months) = (Fixed Interest Rate - Variable Interest Rate) × Loan Term / (Variable Interest Rate × 12)

This formula assumes you're comparing the same loan amount with the same term but different interest rates. The result gives you the number of months after which the variable rate becomes cheaper.

Step-by-Step Calculation

Determine your fixed interest rate and variable interest rate.
Calculate the monthly interest payments for both rates.
Sum the interest payments over time until they are equal.
The point where the cumulative interest payments are equal is your break point.

Example Calculation

Let's say you have a £200,000 mortgage with a 5-year fixed rate of 3.5% and a variable rate of 4.5%.

Using our calculator, you would find that the break point is approximately 3 years and 6 months. This means after 42 months, the variable rate mortgage becomes cheaper than the fixed rate mortgage.

Remember, this is a simplified example. Actual break points can vary based on additional factors like fees, loan terms, and market conditions.

Factors to Consider

When calculating your break point, consider these additional factors:

Early repayment charges: Some lenders charge fees for breaking a fixed rate early.
Inflation: Rising prices can affect the real value of your mortgage payments.
Market conditions: Variable rates can change based on economic factors.
Loan term: Longer loan terms may have different break points than shorter terms.
