This calculator provides an estimate of your monthly mortgage repayments based on the information entered. The figures are for illustrative purposes only, your actual payments may differ, and this does not constitute a mortgage offer.

Potential Property Value

£0

Based on 4.5x your household income plus your deposit, you could potentially purchase a property of this value.

Mortgage Amount
£0

Based on your income, this is the amount lenders may be willing to let you borrow. Actual offers may vary.

How is this calculated?
Lenders typically offer 4-5 times your annual income. We've calculated this by taking your income of £0 and multiplying it by 4.5. Some lenders may offer more or less depending on your circumstances.
Monthly Repayment
£0

Your estimated monthly payment based on the interest rate and mortgage term you entered. Increase your deposit or term to lower this.

How is this calculated?
Monthly repayments are calculated using the standard mortgage amortisation formula, which accounts for both interest charges and principal reduction over the loan term.
Loan to Value
0%

LTV is the percentage of the property value you're borrowing. Lower LTVs are considered less risky and may secure better rates.

How is this calculated?
LTV is calculated by dividing the loan amount by the property value and multiplying by 100. For example, borrowing £90k on a £100k property gives an LTV of 90%. Increase your deposit to lower your LTV.

What affects the amount I pay each month on my mortgage?

Your monthly repayments depend on the loan amount, interest rate, mortgage type, and the length of your term. Even small changes to these factors can significantly impact what you pay. Use our mortgage repayment calculator above.

With a repayment mortgage, you pay off both the interest and the loan amount each month. With interest-only, you only pay the interest – meaning the full loan must still be repaid at the end of the term. Most buyers choose repayment for long-term security.

Yes. If you’re on a variable or tracker rate, your payments can increase or decrease as interest rates move. If you’re on a fixed rate, your payments stay the same for the duration of your deal.

Potentially. You may be able to extend your mortgage term, switch to a lower interest rate, or remortgage to a more affordable deal. A GoMortgage adviser can help compare the best options.

Overpaying can reduce both the interest you pay overall and the length of your mortgage term. Many lenders allow a set amount of overpayments each year without penalty – it’s always worth checking your agreement.

Contact your lender as soon as possible — they may offer temporary payment support such as reduced payments or switching to interest-only. You can also speak with GoMortgage for help exploring refinancing or more manageable deals.
