  • The age of the youngest homeowner (they must be at least 55 years old)
  • Your postcode

With our equity release calculators, only your property details are required for you to see how much you could release from a RIO mortgage. Once you’ve filled in the information, your RIO equity release calculator results are shown instantly in an easy-to-read table.

You can also find personalised calculations for all other eligible equity release plans when you use smartER, an innovative equity release tool that provides real-time calculations across the entire market.

An introduction to retirement interest only mortgages

Retirement interest only mortgages (RIOs) are specifically designed to help homeowners whose current interest only mortgages are coming to an end and who wish to carry their lending into retirement. RIOs offer an alternative to standard equity release plans, where disposable income is available to meet regular lifetime monthly payments.

RIOs work in the same way as an interest only mortgage, whereby the accruing interest on the amount borrowed is repaid each month. The main difference is that RIOs have no end date or fixed term. As a result, RIOs and interest-only mortgages differ in the way the loan is repaid.

With a conventional interest-only mortgage, the balance is repaid at the end of the term agreed with the lender. With a RIO mortgage, the balance is repaid when you die or move into long term care. This is the same as a lifetime mortgage.

RIO mortgages are typically offered by life insurance companies such as Legal & General, specialist RIO lenders like LiveMore and Hodge, plus building societies such as Nationwide. It’s important to remember that RIOs are residential mortgages. This means that you must pass the lender’s income and affordability checks to qualify, and your home may be repossessed if you don’t keep up your monthly interest repayments.
