Equity Release Calculator: How Much Can You Release From Your Home?

Quick answer

Equity release (a lifetime mortgage) lets over-55s borrow against their home with no monthly repayments, but the interest rolls up and compounds: a £50,000 release at 6% roughly doubles to £100,610 owed in 12 years. It can be the right tool, but the compounding is the single number to understand first.

Estimate your release with the calculator above

Enter the current market value of your home and your age (or the age of the youngest homeowner if you own jointly), and the tool above estimates the lump sum you could release. Treat the figure as a starting point for a conversation, not a binding offer. The actual amount a lender will hand over depends on your health, your property type and the exact plan you choose.

What equity release actually is

Equity is simply the share of your home you truly own: the market value minus anything still owed on a mortgage. If your house is worth £350,000 and you have a £20,000 mortgage left, you hold £330,000 of equity. That money is locked up in bricks and mortar. Equity release lets you turn part of it into cash you can spend, without selling up and moving out.

For most people, equity release means a lifetime mortgage. You borrow a percentage of your home's value, the loan is secured against the property, and you keep living there for the rest of your life. Unlike a normal mortgage, you usually make no monthly repayments. Instead the interest is added to the loan each year and the whole balance is repaid when you die or move into long-term care, almost always from the sale of the house. The cash you receive is tax-free, because borrowing is not income.

The other, less common option is a home reversion plan, where you sell a share of your home to a provider for a lump sum but stay living there rent-free. This calculator focuses on lifetime mortgages, which make up the large majority of the UK market and tend to be what people mean when they search for an equity release calculator.

Lifetime mortgages: how much can you release?

The single biggest factor is your age. Lenders work out the maximum loan as a percentage of your property value, and that percentage climbs the older you are. The logic is blunt: the older you are when the plan starts, the fewer years interest has to roll up, so the lender can lend a bigger slice today.

As a rough guide used across the industry, the youngest qualifying borrowers (around 55) might release somewhere near a fifth of their home's value, while someone in their seventies could release around half, and the very oldest applicants more still. Some plans offer a higher percentage if you have certain health conditions or lifestyle factors, because they shorten the expected term of the loan. These are real bands lenders use, but the precise percentage varies by provider and plan, which is why this equity release calculator gives an estimate rather than a guaranteed sum.

The eligibility basics

• You usually need to be at least 55 (joint applicants are assessed on the younger person's age).
• Your property generally needs to be worth at least around £70,000.
• Any existing mortgage must be cleared, normally out of the money you release, so the lender has first charge on the property.
• The home must be your main residence and meet the lender's construction and condition criteria.

How this equity release calculator works

The maths behind the estimate is straightforward. The tool applies an age-based loan-to-value percentage to your property value:

Maximum release = property value × age-based percentage

So if the calculator is using, say, a 35% factor for your age and your home is worth £300,000, the estimated maximum is £300,000 × 0.35 = £105,000. You do not have to take the maximum. Many people release a smaller amount, or set up a drawdown plan where you take an initial sum and leave the rest in a reserve to dip into later, paying interest only on what you have actually drawn.

Because the figure scales with your home's value, an accurate valuation matters. The calculator uses the number you type in, so if you over-estimate what your property is worth, the result will be too high. When you apply for real, the lender sends a surveyor and lends against their valuation, not your optimism. If your home has a small outstanding mortgage, remember the release is gross: you must clear that debt first, so your usable cash is the released sum minus whatever you still owe. A quick check with our loan-to-value calculator can help you see how much of your home is already mortgaged before you start.

Worked example: Margaret, 70, in a £320,000 home

Margaret is 70, widowed, and owns her three-bed semi outright. It is valued at £320,000. She wants a lump sum to help her granddaughter with a house deposit and to replace a leaking roof. Her plan offers an age-70 loan-to-value of around 45%.

• Maximum release: £320,000 × 0.45 = £144,000
• Margaret decides she only needs £60,000 right now, so she takes that as an initial lump sum.
• She arranges a drawdown facility for the remaining headroom, so she can take more later if she needs it, without paying interest on it until she does.

Now the part people underestimate: how the balance grows. Lifetime mortgage interest is usually fixed and compounds, meaning each year's interest is charged on the previous balance plus the interest already added. Suppose Margaret's rate is a fixed 6% a year on her £60,000.

• After year 1, the balance is £60,000 × 1.06 = £63,600.
• After 5 years it is roughly £60,000 × 1.06⁵ = about £80,300.
• After 15 years it is roughly £60,000 × 1.06¹⁵ = about £143,800 — the original loan has more than doubled.

At 6%, a roll-up balance roughly doubles every 12 years. That is why the amount owed at the end can be far larger than the cash you took out. If you want to see how compounding bites over different rates and terms, our compound interest calculator shows the same effect on any starting balance.

A second, smaller scenario

Compare a 58-year-old couple with a £250,000 flat who release the maximum at a younger-age factor of around 25%. That is £250,000 × 0.25 = £62,500. Because they are younger, interest has decades to roll up, so even a modest loan can swell substantially before it is ever repaid. Releasing early and releasing the maximum are the two choices that erode the most inheritance.

How the debt rolls up over time

With most lifetime mortgages you owe nothing month to month, which is the appeal: the cash arrives and your outgoings do not change. The trade-off is that the debt quietly grows in the background. Two features built into modern plans soften this:

• No-negative-equity guarantee: a standard with plans approved by the Equity Release Council, this means you (or your estate) will never owe more than the home sells for, even if the balance has overtaken the value.
• Optional repayments: many current plans let you pay some or all of the interest each year, or make penalty-free voluntary payments up to a yearly limit. Doing this slows or stops the roll-up and protects more of your equity for your beneficiaries.

If keeping money for your family matters, paying the interest as you go turns a lifetime mortgage into something closer to an interest-only loan, and the balance need never grow at all.

Things to weigh up before releasing equity

Equity release is a long-term, often irreversible decision, so it pays to slow down. A few things genuinely worth thinking through:

• It reduces what you leave behind. Every pound released, plus the rolled-up interest, comes off your estate. That can shrink the inheritance your family receives. On the flip side, reducing the value of your estate can interact with inheritance tax planning — though using equity release purely to dodge IHT is rarely sensible without advice.
• It can affect means-tested benefits. Turning property (which is not counted) into cash or savings (which is) may reduce or remove Pension Credit, Council Tax Support or other means-tested help. Check before you release.
• Consider the alternatives first. Downsizing to a smaller home, a retirement interest-only mortgage, drawing more from a pension, or using existing savings may cost you far less in the long run. Compare the lifetime cost against a normal mortgage or a structured pension drawdown before committing.
• Early repayment charges can be steep if you pay the plan off ahead of time, for example because you decide to move and the new property is not eligible to port the loan.

Advice is not optional here. UK rules require you to take regulated financial advice before taking out equity release, and a solicitor must act for you. That is a protection, not a hurdle — an adviser will model the long-term cost against your goals.

Common mistakes people make with equity release

• Taking the maximum just because it is offered. The more you release and the earlier you do it, the more interest compounds. Borrow only what you actually need, and use a drawdown reserve for the rest.
• Forgetting interest compounds, not just adds. A 6% rate does not mean the debt grows by a fixed amount each year — it grows on the growing balance, which is why a loan can double in little more than a decade.
• Ignoring the effect on benefits. A lump sum sitting in a savings account can push you over the capital limits for means-tested benefits, costing you money the release was meant to provide.
• Assuming all plans are equal. Rates, drawdown flexibility, voluntary-payment limits and early repayment charges vary widely. The cheapest headline rate is not always the best plan for your circumstances.
• Treating an online estimate as an offer. This calculator and any other rely on the figures you enter. A surveyor's valuation, your health and the lender's criteria all change the final number.

Equity release applies UK-wide, so the headline mechanics are the same whether your home is in England, Scotland, Wales or Northern Ireland. The differences that bite are local: property values, conveyancing, and how a lump sum interacts with devolved support such as Council Tax Reduction. Your adviser and solicitor will factor in your nation's rules.
