A car instalment is small next to a house price, but it is counted monthly, against the same income, for as long as the agreement runs.
When you apply for a home loan, the car instalment you already pay is not a separate story. It is one of the debt obligations a lender has to consider alongside the proposed home-loan instalment. For this planning comparison, we measure both instalments against the same net income. In the illustration below, a RM945.75 car instalment removes about RM207,925 of home loan at 4.20% over 35 years, whether you plan at a 40% or a 60% debt service ratio (DSR). A shorter five-year car loan on the same amount saves interest but takes even more room while it runs. This guide shows the arithmetic, then looks at whether settling the car loan first, or changing the order of the two purchases, actually helps.
Why a car instalment shows up in a home-loan assessment
Bank Negara Malaysia's (BNM) responsible-financing measures of 18 November 2011 require financial institutions to assess a borrower's ability to afford a facility "based on a prudent debt service ratio", to look at income after statutory deductions for tax and EPF, and to "consider all debt obligations" in assessing affordability. BNM's 2016 statement on the same guidelines adds that lenders must establish that income after statutory deductions, expenditure on necessities and all other obligations can still meet the repayments, with buffers for living expenses and future rate increases. BNM does not publish a single DSR limit; each lender sets its own rules on which income and commitments it recognises.
For planning, PIDM publishes the simplest version of the test: DSR = total monthly debt commitments ÷ net monthly income, with net income meaning pay after EPF, SOCSO and PCB. PIDM advises keeping your DSR between 30% and 40%, and says banks generally accept a DSR below 60% across all commitments. Its own example makes the car-and-house link plain: a person earning RM4,500 net with an RM800 car loan and a RM1,600 home loan is at RM2,400 ÷ RM4,500 = 53.33%, and has only RM300 of monthly room left before 60%. Our DSR guide covers what counts as a commitment and how employment type changes the assessment.
Two features of a car loan matter here. It usually runs long: BNM's 2011 measures cap vehicle financing at nine years for applications received from 18 November 2011. And its instalment does not shrink as you pay it down, so the full RM945.75 stays in the commitments total until the final month. That is why how much car you can afford and how much house you can afford are one question asked twice.
Worked example: the same room, with and without the car
Assume a net income of RM5,000 a month and no other commitments. The car loan is the same hypothetical contract as our five, seven or nine years guide: RM81,000 at a 2.9% flat rate, which gives RM945.75 a month over nine years or RM1,545.75 a month over five. The home loan is priced at 4.20% a year on a reducing balance over 35 years, the maximum tenure for property financing that BNM set for applications made from 5 July 2013. Both rates are illustrations, not current offers. We convert the monthly room left under each DSR ceiling into the home loan that room could carry.
| Scenario | Car instalment | Room left at 40% (RM2,000.00) | Home loan at 40% | Room left at 60% (RM3,000.00) | Home loan at 60% |
|---|---|---|---|---|---|
| No car loan | RM0.00 | RM2,000.00 | RM439,704.94 | RM3,000.00 | RM659,557.41 |
| Nine-year car loan | RM945.75 | RM1,054.25 | RM231,779.47 | RM2,054.25 | RM451,631.94 |
| Five-year car loan | RM1,545.75 | RM454.25 | RM99,867.99 | RM1,454.25 | RM319,720.46 |
How the numbers are reached, using the nine-year row at 40%:
- Room under the ceiling: RM5,000 × 40% = RM2,000.00 of total monthly commitments. Subtract the car instalment: RM2,000.00 − RM945.75 = RM1,054.25 left for a home-loan instalment.
- Instalment per ringgit borrowed: at 4.20% a year the monthly rate is 0.35%. Over 420 months, each RM1 borrowed costs 0.0035 ÷ (1 − 1.0035−420) = RM0.004549 a month (shown rounded; the table uses the full value), so RM1,000 of monthly instalment supports about RM219,852 of loan.
- Home loan the room supports: RM1,054.25 ÷ the unrounded factor = RM231,779.47, the figure in the table. With no car loan the same arithmetic gives RM2,000.00 ÷ the unrounded factor = RM439,704.94. Dividing by the rounded 0.004549 instead gives RM231,754.23 and RM439,657.07, so carry the full factor when you recompute.
- Car instalments: nine years: (RM81,000 + RM81,000 × 2.9% × 9) ÷ 108 = RM945.75; five years: (RM81,000 + RM81,000 × 2.9% × 5) ÷ 60 = RM1,545.75.
Three things stand out. First, at this rate and tenure each RM100 of monthly instalment is worth about RM21,985 of home loan, so the nine-year car loan removes about RM207,925 of borrowing capacity at either ceiling. Second, the five-year loan removes about RM339,837, which is about RM131,911 more than the nine-year loan, even though it costs far less interest over its life; the trade is between total interest and room while the loan runs. Third, in this example the planning ceiling moves the answer more than the nine-year car instalment does: the gap between the 40% and 60% rows with the nine-year loan is RM219,852.47, which is why PIDM's 30% to 40% advice and its "below 60%" observation should not be mixed up.
These are planning figures on net income. A lender may use different income, add necessary expenditure and buffers, apply its own ceiling, and price the loan at a different rate or over a shorter tenure, for example because of your age at the end of the term. None of these rows is an approval or a maximum any bank will lend.
Does settling the car loan first help?
Settling removes the RM945.75 from your commitments, which in this illustration is worth about RM207,925 of home loan at either ceiling. But it costs cash, and the amount depends on the method in your agreement. Our early-settlement guide works the same RM81,000 loan under the Rule of 78 and under the reducing-balance method at the same effective rate; the figures below come from that page.
| Settle after | Months left | Instalments still scheduled | Rule of 78 settlement | Reducing-balance settlement (same EIR) |
|---|---|---|---|---|
| 2 years | 84 | RM79,443.00 | RM66,620.48 | RM66,190.43 |
| 3 years | 72 | RM68,094.00 | RM58,654.90 | RM58,173.88 |
| 5 years | 48 | RM45,396.00 | RM41,172.11 | RM40,803.86 |
The room freed is the same in every row, because the instalment is the same; what changes is the cash you hand over and how long the loan would have run anyway. After three years you would pay RM58,654.90 or RM58,173.88 to stop 72 instalments totalling RM68,094.00, and free RM945.75 a month of room. Before deciding, set that cash against three other uses: the deposit and transaction costs of the property, an emergency reserve, and any more expensive debt such as a credit-card balance. A loan that is close to its end is a weaker case for settling, since the room returns on its own within months; ask the lender how it treats a commitment that ends soon after the home loan starts, because practices differ. Figures exclude any charges in your own agreement and assume no arrears.
House first or car first?
A home loan is usually the larger and longer commitment, so the order matters mostly through time. Take the car loan first and RM945.75 of your room is spoken for during the years you are most likely to apply for a home loan. Take the home loan first and the car budget shrinks instead: on the RM439,704.94 loan in the no-car row, the RM2,000.00 home instalment uses the whole 40% ceiling, so a car would have to fit under a higher ceiling or wait for income growth. If the house matters more, work out the home instalment first with the home-loan calculator, then size the car to the room that is left. A larger car down payment is a third lever: it lowers the instalment without stretching the tenure.
What Kira's calculators assume
This guide uses PIDM's published figures on net income. Kira's tools use their own planning lines: the home-loan calculator applies a 35% planning line on gross income to the home instalment plus any commitments you enter, the DSR calculator shows a 70% reference, and the car-loan calculator prices a flat-rate instalment. All are planning views, not bank rules, and none of them issues an approval. If a bank's answer differs from any of these figures, the bank's assessment is the one that counts.
Once the DSR room is there, the next question is how much cash to put down: the home-loan down payment versus emergency fund guide compares three down payments on one RM500,000 home and the reserve each leaves behind.
Does a car loan reduce how much home loan I can get?
In planning terms, yes. BNM expects lenders to consider all existing debt obligations, so the car instalment sits in the same commitments total as the proposed home-loan instalment. In this guide's illustration, a RM945.75 instalment removes about RM207,925 of home loan at 4.20% over 35 years.
Should I settle my car loan before applying for a home loan?
Not automatically. Settling frees the instalment but uses cash you may need for the deposit and costs, and the settlement amount depends on the method in your agreement. Ask for a written settlement quotation and compare it with the room you would gain.
Is it better to buy a house or a car first?
Neither order suits everyone. A home loan is usually larger and runs longer, so a car loan taken first keeps part of your room occupied for up to nine years, while a car bought after the home loan has to fit the room the home instalment leaves. Work the numbers both ways before you commit.
Calculate with your own numbers
Indicative planning only; not an eligibility assessment, an offer or a guarantee of approval. Each lender applies its own income, commitment and pricing rules. Confirm figures with the bank before you commit to either purchase.
