How home loan instalments work in Malaysia
A Malaysian housing loan is repaid using the reducing-balance method: interest each month is charged only on the outstanding balance, not the original loan. As you pay down the principal, the interest portion of each instalment shrinks and the principal portion grows — even though your monthly payment stays the same.
The monthly instalment formula
The fixed monthly instalment on a reducing-balance loan is:
- M = P × r × (1 + r)n ÷ ((1 + r)n − 1)
where P is the loan amount, r is the monthly interest rate (annual rate ÷ 12), and n is the number of monthly payments (years × 12).
Margin of finance and your down payment
The margin of finance (MOF) is the share of the property price the bank will lend. For your first two homes this is usually up to 90% (sometimes 95% with special schemes), which means a 10% down payment. From the third property onward the MOF typically drops to around 70%. On top of the down payment, budget for stamp duty on the transfer, loan stamp duty, and legal fees.
Interest rates: variable vs fixed
Most home loans in Malaysia are variable-rate, quoted as a spread over the bank's Standardised Base Rate (SBR) — for example "SBR + 0.45%". The SBR moves in step with Bank Negara's Overnight Policy Rate (OPR), so when the OPR rises or falls, your instalment follows. A minority of packages are fixed-rate (common for Islamic home financing), where the rate is locked for the tenure.
Worked example
You buy a home for RM500,000 with a 90% margin (RM450,000 loan), at 4.20% per year over 35 years.
- Monthly rate r = 4.20% ÷ 12 = 0.35%; number of payments n = 35 × 12 = 420
- Monthly instalment ≈ RM2,047
- Total repaid over 35 years ≈ RM859,700 → total interest ≈ RM409,700
- Down payment (10%) = RM50,000, before stamp duty and legal fees
Shortening the tenure or securing a lower rate cuts the total interest sharply — try changing the inputs above to compare.
How to use this calculator
- Choose By property price to enter the price and margin of finance (the loan is worked out for you), or By loan amount to type the loan directly.
- Enter the interest rate the bank quotes and your loan tenure in years.
- Read off your monthly instalment, total interest and total repayment.
- Open the amortisation schedule to see how much principal and interest you pay each year.
Home loan rates & recent changes
Housing loan pricing in Malaysia is tied to Bank Negara Malaysia's monetary policy:
- Standardised Base Rate (SBR): since 1 August 2022, all new retail floating-rate loans are pegged to the SBR, which is linked directly to the OPR. This replaced the older Base Rate (BR) system for new loans and makes it easier to compare packages between banks.
- OPR moves flow through to you: because most home loans are variable, an OPR change by Bank Negara raises or lowers your instalment. Always stress-test your budget against a higher rate before committing.

Frequently asked questions
How is my monthly home loan instalment calculated?
On the reducing-balance method: interest each month is charged on the outstanding balance, and the fixed instalment is set so the loan is fully paid off over the tenure. The formula is M = P × r × (1+r)ⁿ ÷ ((1+r)ⁿ − 1), where P is the loan, r the monthly rate, and n the number of months.
What is the margin of finance?
It's the percentage of the property price the bank will lend. For your first two residential properties it's usually up to 90%, so you pay a 10% down payment. From the third property onward it typically falls to around 70%. A higher margin means a smaller down payment but a larger loan and more total interest.
What is the maximum loan tenure?
Malaysian banks generally allow home loan tenures of up to 35 years, capped so the loan ends by age 70 (some go to 75). A longer tenure lowers the monthly instalment but increases the total interest you pay over the life of the loan.
Is the interest rate fixed or variable?
Most conventional home loans are variable-rate, priced as a spread over the Standardised Base Rate (SBR), so the instalment changes when Bank Negara moves the OPR. Some packages — often Islamic home financing — offer a fixed rate for the full tenure. This calculator assumes the rate you enter stays constant, so re-run it with a higher rate to stress-test.
Does this include MRTA, insurance or fees?
No. The figure is the pure principal-and-interest instalment. It does not include MRTA/MLTA mortgage insurance, fire insurance, legal fees, valuation, or stamp duty. Use our Stamp Duty & Legal Fees calculator to estimate the upfront transaction costs.
Can I reduce the total interest?
Yes. A lower interest rate, a shorter tenure, or making extra/lump-sum payments into the principal all reduce total interest. Many Malaysian loans are flexi or semi-flexi, letting you park extra cash to lower the interest charged while keeping access to the money.
