An equity release calculator works very differently from a standard mortgage or remortgage calculator, with each using a completely different set of criteria. For example, when calculating residential mortgages, lenders use a range of criteria to calculate how much they will lend you. This includes your income, age, and credit history. Interest rates are typically based on the amount you want to borrow against the value of your home – which is known as the loan-to-value (LTV). Generally, the higher the LTV, the higher the interest rate. With our online equity release calculators, the amount you can borrow is calculated using the age of the youngest applicant, the property value and, in some cases, your postcode and property type. The older you are, the higher the LTV becomes and the larger the maximum equity release will be. Residential mortgage calculators also require you to pass individual lenders affordability criteria and credit checks. With an equity release calculator, no personal details such as these are required: your income and credit status are not typically part of the final calculation.
