Save at 5.6% or Overpay Your Mortgage? The Real Numbers for UAE Homeowners

If you have a mortgage in the UAE and some spare cash, this autumn has handed you an unusual choice. Banks are suddenly paying savings rates that look close to the cost of a variable rate home loan. So should that bonus, or the money sitting in your current account, go into a high-interest savings account or towards your mortgage? The honest answer depends on three numbers: the rate on your loan, what the savings account really pays over a full year and the fee your bank charges for paying early. We worked through all three with this week's figures.

Why banks are suddenly paying 5.6%

UAE banks have been lending faster than they have been taking in deposits. According to Bloomberg figures reported by Enterprise AM, credit grew 18.1% in the second quarter of 2026 compared with a year earlier, while deposits grew about 14%. That pushed the banking system's loan-to-deposit ratio above 80%, from 77.7% in 2025.

When banks need deposits, they pay more for them. First Abu Dhabi Bank raised its savings campaign rate to 5.6%, up from 4% in its previous campaign, and Emirates NBD is reported to be advertising up to 5.5% on some larger new deposits. For savers, that is good news. For homeowners, it raises a fair question: if the bank will pay you 5.6%, is there any point in paying down a mortgage that costs about the same?

What the 5.6% offer actually pays

The details matter more than the headline. On FAB's iSave page, the 5.60% a year applies to new funds deposited from 1 September to 31 December 2026. Your starting point is your overall balance with FAB on 31 August 2026, so moving money between your own FAB accounts is unlikely to count as new. The account is only open to UAE residents with a valid Emirates ID.

Outside the campaign, the normal iSave rate is much lower: up to 2.465% a year on balances under AED 500,000. During the campaign, FAB pays its normal rate as usual and then tops it up to 5.60%, and it says the campaign will be settled within 45 days of 31 December 2026. The page does not say what campaign money earns after that date. Money from FAB's previous campaign kept earning 4%, so the real figure could turn out higher than the normal rate we use below. Interest is worked out on your average balance each month.

So the real question is not "what is the rate?" but "what will this money earn over the next twelve months?" Here is AED 100,000 of new money deposited on 20 October 2026:

Our calculation from FAB's published iSave terms on 19 October 2026, simple interest, ignoring compounding. It assumes the money is new to FAB, the balance stays under AED 500,000 and the money earns the normal rate after 31 December, which FAB's page does not confirm either way. Rates can change.

That is still a good return for cash you can reach any time. But over a full year it is closer to 3.1% than 5.6%, and that is the number to compare with your mortgage.

What your mortgage is costing you

Most UAE mortgages start with a fixed rate for one to five years and then move to a variable rate based on 3-month EIBOR plus a margin. As an example of today's pricing, FAB's mortgage page on 19 October showed:

• Fixed: 3.99% for one, two or three years, or 4.19% for five years, for customers who transfer their salary and take a FAB credit card. Without a salary transfer, 4.24% and 4.44%.
• After the fixed period: 3-month EIBOR plus 1.5% with a salary transfer, or plus 1.89% without, with a minimum rate of 1.99%.

The Central Bank of the UAE published 3-month EIBOR at 4.205% on 16 October 2026. Add a 1.5% margin and a variable loan costs about 5.705% a year. On FAB's margin, that is what a homeowner whose fixed period has ended would pay now. Margins differ by bank: HSBC listed 1.09% on 16 October, which works out at about 5.3%. Either way, it is well above the 3.1% the savings account earns over a year.

If you are not sure which rate you are on, your offer letter or your bank's app will show it, along with the date any fixed period ends. Our guide to fixed and variable rates explains how the two work.

AED 100,000 two ways: the 12-month maths

Take a homeowner who owes AED 1,000,000 with 20 years left and has AED 100,000 to spare. They can put it in savings or pay it off the loan and keep the same monthly payment, so the loan ends sooner. Here is what each choice is worth in the first year:

Our calculations: AED 1,000,000 outstanding over 240 months, monthly payment unchanged after the overpayment, rate held steady for the year. The 1% fee is an example; your own fee is set in your offer letter.

Two things stand out. On a variable rate, paying down the loan beats the savings account clearly, by about AED 1,800 to AED 2,800 in the first year alone, and it keeps saving you interest every year after that. On a 3.99% fixed rate with a fee to pay, the first year is roughly a tie. In that case the real difference is not the return, it is whether you can get the money back if you need it.

And the gap does not close quickly if rates fall. Even if EIBOR dropped by a full percentage point, the variable loan in our example would still cost about 4.7%, well above the normal savings rate of up to 2.465%.

The fee that can change the answer

Paying part of your mortgage early is called a partial settlement, and banks can charge for it. The Central Bank of the UAE caps the charge: its fee schedule under Regulation 29/2011 sets partial settlement charges at a maximum of 1% of the outstanding balance or AED 10,000, whichever is less. Within that cap, the exact fee, any free allowance and any minimum payment are set by your bank and written in your offer letter.

Some banks let you pay a slice of the loan each year for free. FAB, for example, says its mortgage allows partial settlement of up to 25% of the outstanding loan each year without fees during the variable rate period. Note the last part: that free allowance applies once the fixed period is over, not during it.

This is why the same AED 100,000 can be a clear win for one homeowner and a coin toss for another. Before you decide, find three things in your offer letter or ask your bank: the fee, whether there is a free annual allowance and whether it applies during your fixed period.

The middle path: save now, pay down later

Here is a detail that is easy to miss. For the 73 days from 20 October to 31 December, the savings account pays 5.60% while a variable mortgage costs about 5.705%. On AED 100,000, that is about AED 1,120 earned against about AED 1,140 of mortgage interest. The difference is around AED 20.

So if you are on a variable rate and not yet sure what to do, parking the money in savings until the end of December costs you almost nothing and keeps your options open. If nothing has changed by January, you can pay down the loan then. Two checks before you rely on this:

• The campaign terms. FAB says the campaign will be settled within 45 days of 31 December. Its iSave page lists no limits on withdrawals, but the 5.60% is subject to separate campaign terms and conditions, so read those before planning to move the money out in January.
• Your fee-free allowance. If your bank offers a free yearly allowance, ask when the year resets. Paying down just after it resets can save the fee.

On a fixed rate, the same idea works over a longer horizon. Keep the money where you can reach it, and plan to pay down the loan when your fixed period ends, especially if your bank allows free partial payments once you move to the variable rate.

Shorter loan or lower payment?

When you pay a lump sum off your mortgage, the bank will usually either keep your monthly payment the same and shorten the loan, or keep the end date and lower your payment. Ask which options your bank offers, because the difference over the life of the loan is large. Using the same AED 1,000,000 loan at 5.705% over 20 years:

Our calculations, assuming the rate stays at 5.705% for the whole loan. It will not, so treat these as a way to compare the two choices, not as a forecast.

Shortening the loan saves far more interest. Lowering the payment has its own uses, though. It frees up about AED 700 a month, and because banks count your monthly loan payments when they work out how much more you can borrow, a lower payment can help if you plan to buy a second property or need another loan later. Our article on how much you can borrow explains how that limit works.

When keeping the cash is the right call

The maths is only half of it. Money you pay into a mortgage is hard to get back: with a standard home loan, getting cash out again generally means applying to borrow more, with a new approval and new fees. Keep the cash, or at least part of it, if any of these apply to you:

• You do not have an emergency fund. A common rule of thumb is three to six months of essential spending in an account you can reach at once. Build that first.
• You may buy again soon. In Dubai, an expat buying a ready home needs about 28% of the price in cash once fees are added, as our down payment guide shows. If a move or a second property is likely in the next year or two, that cash is worth more in your hands.
• You are on a fixed rate and would pay a fee. As the table above shows, the first year is close to even, and flexibility tips the balance.
• You have dearer debt. If you carry a credit card balance or a personal loan at a higher rate than your mortgage, paying that off first saves more. It can also lift what banks will lend you, because the payments count against your income.

A five-step checklist

1. Find your rate and its end date. Check your offer letter or your bank's app for your current rate, whether it is fixed or variable and when it changes.
2. Find your partial settlement terms. Note the fee, any free yearly allowance, any minimum amount and whether payments are allowed during the fixed period.
3. Work out the real savings return. Use what the account pays over the next twelve months, including the rate after any campaign ends, not the headline rate.
4. Set your emergency fund aside first. Only compare the money you will not need at short notice.
5. Choose shorter loan or lower payment, and get it in writing. Ask the bank for the new payment schedule before you transfer the money.

If your fixed period is ending soon, the bigger saving may come from your rate rather than a lump sum. Our guide to refinancing your UAE mortgage shows how to compare your bank's new offer with a switch.
