How equity release works
The most common form of equity release is a lifetime mortgage: a loan secured against your home that you don't have to repay until you die or move into permanent long-term care. You keep full ownership of your home, and you can take the money as a single lump sum or in smaller amounts over time through a drawdown facility. A less common alternative, a home reversion plan, works differently: you sell all or part of your home to a provider at less than its market value, in exchange for a cash sum and the right to live there rent-free for life.
With most lifetime mortgages, you don't make any monthly repayments. Instead, interest is added to the loan each year and rolls up, meaning next year's interest is charged on the interest as well as the amount you originally released. Some providers offer interest-only or partial-payment versions, where paying some or all of the interest each month slows this growth considerably.
How much could you release?
How much you can release depends mainly on your age and your property's value, because lenders base their maximum loan-to-value on how long they expect interest to roll up before the loan is likely to be repaid. There's no single official rate table for this, the way there is for Income Tax bands or National Insurance thresholds: every lender sets its own figures, and they move with market interest rates. The ranges below are a broad illustration compiled from published UK provider rate cards, not a specific quote.
| Age of youngest homeowner | Illustrative % of property value |
|---|---|
| 55 to 59 | 20% to 30% |
| 60 to 64 | 25% to 35% |
| 65 to 69 | 30% to 40% |
| 70 to 74 | 35% to 45% |
| 75 to 79 | 40% to 50% |
| 80 to 84 | 45% to 55% |
| 85 and over | 50% to 58% |
Broad illustration only. Real offers vary by lender, current interest rates, property type, and sometimes health and lifestyle underwriting.
How rolled-up interest grows
Because interest compounds every year, a lifetime mortgage balance can grow faster than it first appears. Age UK's own guidance gives a useful example: a £20,000 loan can roughly double in around 11 years at a fixed rate of 6.5% a year. The longer the term and the higher the rate, the faster this happens, which is why it's worth projecting the balance forward, not just looking at the amount released today.
No negative equity guarantee and other protections
Every lifetime mortgage from an Equity Release Council member comes with a no negative equity guarantee: when your home is eventually sold, neither you nor your estate will ever have to repay more than it sells for, even if rolled-up interest has technically grown the debt beyond that. Council members must also let you make penalty-free voluntary repayments, guarantee your right to stay in your home for life, and waive early repayment charges if you need to move permanently into care. Always check a specific plan meets these standards before proceeding.

Frequently asked questions
Is this the same as a lifetime mortgage calculator?
Yes. A lifetime mortgage is simply the most common type of equity release, so a lifetime mortgage calculator and an equity release calculator are generally covering the same ground, and this tool works for either search. It doesn't cover home reversion plans, the less common alternative, which work differently since they involve selling part of your home rather than borrowing against it.
Do I need to provide personal details to use this calculator?
No. This calculator runs entirely in your browser: you don't need to enter your name, contact details, or any identifying information, and nothing you type into it is saved, sent anywhere, or used to generate leads for equity release providers. It's built to give you a private, no personal data starting estimate before you speak to a regulated adviser, not to collect your details.
How much equity could I release from my home?
It depends on your age, your property's value, and the individual lender's own terms; there's no single official rate table for this, unlike Income Tax or National Insurance bands. As a very broad illustration, homeowners in their late 50s can typically release somewhere around a fifth to a third of their property's value, rising to around half or more from their mid-70s onwards, because lenders factor in life expectancy. Use the estimate tool above for a rough range based on your own age and property value, but treat it as a starting point, not a quote.
Why does the amount I can release depend on my age?
Most equity release is a lifetime mortgage, which isn't usually repaid until you die or move into permanent long-term care. Lenders base how much they'll lend on how long they expect interest to roll up before the loan is likely to be repaid, so an older applicant, with a shorter remaining life expectancy on average, can typically borrow a higher percentage of their home's value than a younger one.
How does interest work on a lifetime mortgage?
With the most common type, a roll-up lifetime mortgage, you don't make any monthly repayments. Instead, interest is added to the loan each year and then charged interest itself the following year, known as compounding. This means the debt can grow quickly: Age UK's own guidance gives the example of a £20,000 loan roughly doubling in around 11 years at a fixed rate of 6.5% a year. Some lenders offer interest-only or partial-payment versions instead, where paying some or all of the interest each month slows this growth.
Could I end up owing more than my home is worth?
Not if your plan carries a no negative equity guarantee, a standard included with every lifetime mortgage from an Equity Release Council member. It means that when your home is eventually sold, neither you nor your estate will ever have to repay more than it sells for, even if rolled-up interest has technically grown the debt beyond that figure. Always check this guarantee applies before taking out any plan.
Do I have to get financial advice to take out equity release?
Yes. Unlike a standard loan calculator, equity release is a regulated product, and UK law requires you to take advice from an FCA-authorised equity release adviser before any provider can offer you a plan. This calculator gives you a starting estimate to bring to that conversation; it isn't a substitute for it.
Is the money I release from equity release taxable?
No. The cash you receive from equity release is tax-free, whether taken as a lump sum or in smaller amounts. However, it can affect your entitlement to means-tested benefits such as Pension Credit and Council Tax Reduction, and it reduces the value of your estate for inheritance purposes, so it's worth checking both before going ahead.
What's the difference between a lifetime mortgage and a home reversion plan?
A lifetime mortgage is a loan secured against your home; you keep full ownership, and interest rolls up until the loan is repaid from your estate. A home reversion plan is different: you sell all or part of your home to a reversion company at less than its market value, in exchange for a cash lump sum, and you keep the right to live there rent-free for life. Lifetime mortgages are far more common, and this calculator's roll-up projection only models a lifetime mortgage, not a home reversion plan.
Can I make repayments to reduce how much interest builds up?
Often, yes. Equity Release Council standards give customers the right to make penalty-free voluntary repayments, subject to the lender's own limits, and paying even some of the interest each month can significantly slow how quickly the balance grows compared with letting it fully roll up. This calculator's roll-up projection assumes no repayments are made, so it shows the fastest-growing, worst-case path; ask a prospective lender about their specific voluntary repayment terms.
Methodology and assumptions
This calculator assumes:
- The illustrative range tool uses broad, wide age bands compiled from published UK lifetime mortgage provider rate cards. It is not a quote, and does not use any official government table, because none exists for this figure.
- The roll-up projection assumes a standard roll-up lifetime mortgage, with a fixed interest rate for the whole term and no repayments made, so interest compounds annually on the full balance every year.
- If you enter an assumed property growth rate, it is applied evenly every year; real property values do not grow smoothly and can fall as well as rise.
- Neither tool models health or lifestyle-based "enhanced" terms, drawdown facilities, home reversion plans, or fees, all of which can change the figures a real lender offers.
- All figures are rounded to the nearest penny.
