Equity Release Interest Rates Explained

Interest is the beating heart of any equity release decision. Unlike a normal mortgage, where you chip away at the balance every month, a lifetime mortgage usually lets the interest roll up and compound, so the rate you are charged, and how you manage it, matters enormously over the decades a plan may run. A difference of even half a percentage point can add up to tens of thousands of pounds.

This guide explains how equity release interest rates actually work: why they are fixed for life, what drives the figure you are offered, how compounding turns a modest rate into a large debt, and the practical levers you can pull to keep the cost down. Get this right and equity release can be a sensible tool; misunderstand it and it becomes an expensive surprise for your heirs.

How equity release rates work

The defining feature of a lifetime mortgage rate is that it is fixed for the life of the loan. Equity Release Council standards require this: your rate is set at outset and never changes, giving you total certainty about how the balance will grow (a small number of plans use a capped variable rate instead, with a ceiling it can never breach). Because you typically make no monthly repayments, that fixed rate is applied to a balance that grows each year: the interest you do not pay is added to what you owe.

This is very different from a residential mortgage, where a fixed rate lasts only a few years before you remortgage. With equity release the rate you agree today could still be running in thirty years’ time. That certainty is valuable, but it cuts both ways: if market rates fall after you take out your plan, you do not automatically benefit, and switching to a cheaper deal may trigger an early-repayment charge.

It is worth being clear about why lenders can offer a rate fixed for so long when ordinary mortgage lenders cannot. Equity release providers typically fund their lending with very long-dated assets, the kind held by annuity and pension businesses, matched to liabilities decades into the future, so a loan that runs for thirty years suits them rather than frightens them. That structural fit is part of why the market exists at all, and why the rates, while higher than a mainstream mortgage, are far lower than any unsecured borrowing an older homeowner could otherwise access.

What drives your rate

Several factors shape the rate a lender offers you. The wider interest-rate environment sets the baseline, equity release rates broadly track long-term gilt yields and the general cost of borrowing. On top of that, lenders look at your loan-to-value (releasing a smaller percentage of your home usually earns a lower rate), your age, the type and value of your property, and whether you qualify for an enhanced plan on health grounds. In 2026, typical rates sit broadly in the 6% to 7.5% region, though the range is wide.

The loan-to-value point is one many people miss. Lenders reserve their sharpest rates for those borrowing a conservative slice of their home’s value, because a smaller loan has more headroom before the rolled-up debt approaches the property’s worth. Push towards the maximum you are allowed and the rate usually creeps up to reflect the greater risk. So the choice of how much to release and the rate you pay are linked: borrowing less can be cheaper twice over, once on the smaller balance and again on the keener rate. It is a neat illustration of why the headline figures in a comparison table only tell part of the story.

The power of compounding

Compounding is what makes equity release costs grow, and why the headline rate deserves such attention. Because unpaid interest is added to the loan, the following year’s interest is charged on a bigger balance. A handy shortcut is the “rule of 72”: divide 72 by the interest rate to estimate how many years it takes the debt to double. At 6.5%, that is roughly eleven years; at 7.5%, under ten. The table shows how the same £100,000 loan grows at two different rates, with no repayments made.

The gap between the two columns is the cost of a rate that is just 1.5 percentage points higher, well over £180,000 after twenty-five years on the same starting loan. That is why shopping around and structuring the plan well matters so much, and why this sits naturally alongside broader estate and inheritance tax planning.

Notice, too, how the growth accelerates. In the early years the balance climbs gently; by the later rows it is leaping upward, because compounding feeds on itself. This is why equity release tends to look most attractive when the expected term is shorter, later in life, or where health suggests a briefer horizon, and why taking it very early, then living for another three decades, is precisely the scenario where the numbers can turn uncomfortable. Time is not neutral here; it is the single biggest lever on the eventual cost, and it works against you the longer the plan runs.

AER, MER and how it is quoted

You may see rates quoted in two ways. The MER (monthly equivalent rate) is the rate applied each month; the AER (annual equivalent rate) shows the true yearly cost once monthly compounding is taken into account, and is always slightly higher than the headline monthly figure annualised. When comparing plans, make sure you are comparing like with like, ideally the AER, because a plan quoting a lower monthly rate is not necessarily cheaper once compounding is included. Your adviser’s illustration will spell this out clearly.

The frequency of compounding matters more than it first appears. A plan that adds interest monthly costs a shade more than one that adds it annually at the same nominal rate, because the balance it charges against ticks up twelve times a year rather than once. The difference is small in any single year but, stretched over decades, it compounds along with everything else. This is another reason not to be dazzled by a low-looking monthly figure: the regulated illustration you receive is required to show the total amount payable over a range of scenarios, and that total is the number worth fixing your attention on.

Ways to manage the cost

A fixed, compounding rate does not mean you are powerless. There are several practical ways to keep the total cost down, and using them together can save a substantial sum over the life of the plan.

• 1

  Choose drawdown over a big lump sum

  Take money in stages so interest only builds on what you have actually withdrawn, not on cash sitting unused.

• 2

  Make voluntary repayments

  Council-standard plans let you repay a set percentage each year penalty-free; even covering the monthly interest keeps the balance flat.

• 3

  Release only what you need

  A smaller loan compounds more slowly and protects more of your estate.

• 4

  Secure the lowest rate you qualify for

  A lower loan-to-value or an enhanced plan on health grounds can meaningfully cut the rate.

• 5

  Review the plan over time

  If rates fall sharply, switching may be worthwhile, but weigh any early-repayment charge first.

Comparing deals

The equity release market has dozens of plans, and the cheapest headline rate is not always the best fit, flexibility on voluntary repayments, the size of the drawdown reserve, and early-repayment terms all matter. A whole-of-market adviser can compare across lenders rather than a single provider’s range, which is where much of the value of advice lies. It is worth reading whether a financial adviser is worth it when weighing the cost of advice against the potential saving.

A slightly higher rate can occasionally be the better buy. A plan charging a fraction more but offering a generous penalty-free repayment allowance, a larger reserve, or gentler early-repayment terms may cost you far less in practice than a rock-bottom rate that locks you in rigidly. The right comparison weighs the whole package against how you actually expect to use it, whether you intend to service the interest, whether you might repay early, and how likely you are to move house. That is judgement, not arithmetic, and it is precisely the part a good adviser earns their fee on.

Getting advice

Regulated advice is legally required before you take out any equity release plan, and given how much the rate and structure affect the long-term cost, that requirement is a genuine protection. An adviser will compare rates across the market, model how the debt grows under different scenarios, and check that equity release beats the alternatives for you. Vetted Wealth matches you, at no cost, with an independently vetted, FCA-regulated specialist, in Devon, Cornwall or wherever you live.

This is information, not personal advice. Equity release is a long-term commitment: the interest compounds, it reduces the value of your estate, and it may affect your entitlement to means-tested benefits. Property values, and the equity remaining in your home, can fall as well as rise.
