Secured Loan Calculator FAQ
Everything you need to know about secured loans, loan-to-value, and repayment structures in the UK.
A secured loan is a loan that is secured against an asset, most commonly a homeowner’s property. Because the lender has the security of the property, secured loans typically allow for larger borrowing amounts and longer terms than unsecured personal loans, but the property can be repossessed if repayments are not kept up.
Loan-to-value is the loan amount expressed as a percentage of the property’s value. It is calculated by dividing the loan amount by the property value and multiplying by 100. Lenders use LTV to assess risk, and a lower LTV generally means access to more competitive interest rates.
A second charge mortgage is a type of secured loan. It sits behind an existing first mortgage on the property, meaning the first mortgage lender is repaid first if the property is sold or repossessed. Secured loans and second charge mortgages are often used interchangeably to describe the same type of borrowing.
With capital & interest repayment, each monthly payment reduces both the loan balance and the interest owed, so the loan is fully repaid by the end of the term. With interest-only repayment, monthly payments cover only the interest, and the original loan amount remains owed in full until it is repaid separately, often through the sale of the property.
It is often possible to get a secured loan with a lower credit score than would be accepted for an unsecured loan, because the lender has the security of the property. However, a lower credit score typically results in a higher interest rate being offered, reflecting the increased risk to the lender.
Missing repayments on a secured loan can result in additional fees, damage to your credit rating, and ultimately repossession of the property used as security, since the loan is legally tied to that asset. Anyone struggling with repayments should contact their lender as early as possible to discuss options.
