What is Reducing Balance Mortgage?
Ипотека, при которой проценты начисляются на остаток основного долга, снижающийся с каждым платежом, по мере погашения кредита процентная составляющая уменьшается.
Description
In a reducing balance mortgage, each monthly payment includes both principal and interest. As the principal is gradually repaid, the interest portion (calculated on the remaining balance) decreases. This contrasts with a flat-rate mortgage where interest is calculated on the original loan amount throughout the term, regardless of how much principal has been repaid.
For a AED 1.5 million mortgage at 5% over 25 years on a reducing balance basis, the monthly payment is approximately AED 8,770. In month one, about AED 6,250 goes to interest and AED 2,520 to principal. By year 15, the split reverses, more goes to principal than interest. The total interest paid over 25 years is approximately AED 1.13 million. On a flat-rate basis at the same 5%, total interest would be AED 1.875 million, 65% more expensive.
Формула
Monthly Payment = P × [r(1+r)^n] / [(1+r)^n − 1], where P = principal, r = monthly rate, n = total monthsHow to interpret
The reducing balance method means your early payments are mostly interest, with relatively little going to principal reduction. This is why overpaying in the early years of a mortgage has an outsized impact on total interest paid. Even a small additional monthly payment applied to principal in years one through five can save tens of thousands in interest over a 25-year term.
When comparing mortgage offers, always request the effective annual rate and a full amortization schedule rather than focusing on the headline rate. Two loans with the same rate but different fee structures can have materially different total costs over the loan lifetime.

All UAE banks now use reducing balance for mortgage calculations, as mandated by the UAE Central Bank. However, advertised rates and actual effective rates can differ. Always request the effective annual rate (EAR) and a full amortization schedule before signing. Islamic financing products (Ijara, Murabaha) use different structures but the economic effect is similar.
Frequently asked questions
A mortgage where interest is calculated on the outstanding principal balance, which decreases with each payment, resulting in progressively lower interest charges over the loan term.
The standard formula is: Monthly Payment = P × [r(1+r)^n] / [(1+r)^n − 1], where P = principal, r = monthly rate, n = total months. Applying it consistently lets you compare projects on a like-for-like basis, which is the point of the metric.
