Releasing home equity: what it costs per month, and when it makes sense

Releasing home equity means borrowing money against your house. Your equity doesn't shrink; your debt grows.

Releasing €100,000 costs roughly €507 a month at 4.5% over thirty years on a repayment basis. For €50,000 that's €253 and for €30,000, €152.

Below are the amounts for every combination, the three ways of doing it, and the question that really matters: when does it make sense and when doesn't it.

What it costs per month

Repayment mortgage over thirty years, so you repay and your payment stays level:

Choose interest-only and you pay interest alone while the debt remains:

Interest-only is cheaper monthly and more expensive over the term, because you repay nothing. At the end the whole debt is still there.

What it costs in total

The monthly payment is the figure people look at. The total is the figure that matters.

Repayment over thirty years at 4.5%:

Borrowing a hundred thousand costs over eighty-two thousand in interest across thirty years. That isn't an argument against doing it; it's an argument for knowing what you're doing it for.

The three routes

Increasing your existing mortgage. Usually the cheapest, because you get the rate matching your risk band. That's exactly where loan to value comes in: borrowing more raises your LTV and can push you into a more expensive band.

A second mortgage. A separate loan with the same or another lender. Often a higher rate, since it ranks behind your first mortgage.

An equity-release mortgage. For homeowners from roughly sixty. You make no monthly payments; interest is added to the debt. Repayment happens on sale or death.

That third one needs separate explanation, because it works differently from what people assume.

How an equity-release mortgage works

No monthly payments sounds attractive. The price is that your debt grows every year, faster than most people expect.

On €100,000 released:

At 5% your debt doubles in roughly fourteen years. At 6%, twelve.

That needn't end badly, because your property value usually grows too. At a €450,000 property, €100,000 released at 5%, and 2% appreciation a year:

Equity keeps growing in this scenario, just more slowly than without the release. Set appreciation to zero and equity does fall, sharply.

That's the core of the trade-off: an equity-release mortgage is a bet that your property rises faster than your rate. At 5% interest and 2% appreciation you lose that bet a little every year; you just don't notice because the absolute figure keeps growing.

Most providers cap what you may release, depending on your age and property value, precisely to prevent the debt overtaking the value.

When it makes sense

Four situations where it adds up.

For renovation or energy improvements. The investment usually raises your property's value, and the interest is often deductible because the loan is used for the home. For consumption that deduction doesn't apply, which makes a considerable difference to your net payment.

To clear more expensive debt. Replacing a 10% consumer loan with a 4.5% mortgage is a direct saving. Do include the arrangement costs.

When you'd otherwise never use the equity. Someone of seventy-two with a paid-off house and a tight pension holds substantial wealth doing nothing. Equity release converts that into spendable income.

At a low rate over a long horizon. If your rate sits well below your expected real return, it can work out arithmetically. Calculate it rather than assuming it.

When it doesn't

Four situations where it goes wrong.

For consumption. A car, a trip, a boat. You pay interest for thirty years and the collateral is your home. At €30,000 for a car you're talking about €24,722 of interest across the term.

To invest. Borrowing to invest means losses count twice: your investment falls and your debt remains. That's a different order of risk from investing your own money.

When your payments are already tight. €507 a month extra is €507 a month less room, every month, for thirty years.

When you plan to move within a few years. You won't recoup the arrangement, valuation and advice costs.

Equity as a bridge to your state pension

For anyone following this series there's one application that looks logical and disappoints.

Three quarters of the wealth of non-millionaire Dutch households sits in the family home. The temptation to use that equity to bridge the years to state pension age is therefore strong.

Arithmetically it works poorly. Releasing €100,000 to cover seven bridge years costs:

Those payments come on top of your spending and therefore reduce exactly the room you were trying to create. You've received a hundred thousand and added six thousand a year of fixed costs, just as your income stopped.

An interest-only variant or equity release lowers that payment, but then your debt grows during a period when you have no income to carry it.

The honest conclusion: home equity is real wealth, but it's the least suitable wealth for financing early retirement. How to set up that calculation is in the article on your FIRE number.

The exception is selling and moving somewhere smaller. Then the equity is released without any interest cost, and that's the one route where property wealth genuinely becomes spendable.

How much can you release?

Two limits determine it.

Your property value. Your total mortgage may be at most a hundred percent of market value. At a €450,000 property with €200,000 outstanding, theoretical room is €250,000.

Your income. That's usually the binding limit. What you can borrow is calculated on assessable income, and after your pension date that's usually lower. That's exactly why equity-release mortgages exist: they assess differently.

With equity release the limit is mainly your age and property value, because the provider wants the accrued debt still covered on sale.

How Gylder fits in

Releasing equity changes two things at once: your outstanding balance and your monthly payment. Both are precisely what the property model tracks.

Gylder models your mortgage as it's actually built: multiple loan parts, each with its own repayment type, rate, term and penalty-free allowance. Release equity and it appears as an additional loan part with its own conditions.

Your property value moves between your own valuations using the official house-price index for your region. That keeps your equity right in the years you enter nothing, and shows what the release does to your net position.

And because your loan to value moves with it, you immediately see whether you're dropping below a threshold or shooting through one. Borrowing more can push you into a more expensive risk band, raising the rate on your entire mortgage rather than just the new part.

What this doesn't tell you

The rates are worked examples. What you pay depends on your risk band, your fixed-rate period and your lender. Get a quote.

Arrangement costs aren't included. Advice, valuation, notary and sometimes a fee. Expect several thousand euros paid on top or added to the loan.

Interest deductibility isn't included. Use the loan for your own home and interest is usually deductible, lowering your net payment. For consumption it isn't. That's tax territory and the rules change; look up the current treatment.

Appreciation is an assumption. The equity-release table shows how sensitive the outcome is to it.

This isn't advice. Using your home as collateral is a decision with thirty years of consequences. Have it calculated.

Frequently asked questions

What does releasing €30,000 cost? Roughly €152 a month on a repayment basis over thirty years at 4.5%, or €112 interest-only. Across the term you pay €24,722 of interest on the repayment option.

What does releasing €50,000 cost? Roughly €253 a month on repayment at 4.5%, or €188 interest-only. Total interest across thirty years: €41,203.

What does releasing €100,000 cost? Roughly €507 a month on repayment at 4.5%, or €375 interest-only. Total interest across thirty years: €82,407.

How much equity can I release? Up to a hundred percent of your property value, though in practice your income is the binding limit. After your pension date that income is usually lower, shrinking the room.

What is an equity-release mortgage? A mortgage without monthly payments where interest is added to the debt. Repayment happens on sale or death. At 5% the debt doubles in roughly fourteen years.

Is releasing equity sensible? For renovation or clearing more expensive debt, often yes. For consumption rarely, and to invest rarely. For bridging the years to state pension age it works poorly, because the payment removes exactly the room you wanted to create.
