An in-house car loan is financing arranged by the car dealer itself rather than a bank. The dealer is the lender, so approval is fast, credit checks are light, and the loan doesn't show up in your Total Debt Servicing Ratio. That last point is why so many buyers sign one. The catch is the price of that convenience. As of June 2026, in-house schemes commonly charge a flat rate of 3.5% to 6% per annum, against roughly 2.78% at the banks, and they sit outside the Monetary Authority of Singapore's motor vehicle loan rules. On a S$60,000 used-car loan over seven years, that gap can mean S$10,000 or more in extra interest. This guide lays out the 2026 numbers, the fees dealers don't put on the poster, and the rare cases where in-house actually wins.
When you buy a car here, the money usually comes from one of two places. A bank or finance company lends it to you under a hire purchase agreement, or the dealer lends it directly through its own financing arm. The second route is what people mean by an in-house car loan, sometimes called dealer financing or seller financing.
The difference matters because of who sets the rules. A bank loan follows a fixed rulebook set by the regulator, so the rate, the maximum you can borrow and the tenure are broadly standardised across lenders. An in-house loan follows the dealer's own terms, which is why two dealers can quote wildly different rates for the same car. Before you sign either, it helps to understand a standard bank loan structure so you have a baseline to compare the dealer offer against.
Dealers advertise in-house financing on the flat rate, the same way banks do. A flat rate charges interest on your full original loan for the entire tenure, even as you pay the balance down, so the true cost is always higher than it looks. The figure that reflects what you really pay is the effective interest rate, or EIR.
As of June 2026, banks quote new-car flat rates from around 2.78% per annum, which works out to an EIR near 5.2%. In-house schemes commonly run 3.5% to 6% flat, pushing the EIR to roughly 6.5% to over 10%. Some dealers dangle teaser flat rates as low as 1.68% to win the sale, then claw the margin back through an inflated car price or add-on fees, so a low sticker rate is not proof of a cheap loan. Compare every offer on EIR, never the flat rate. We unpack why the two differ so much in our EIR glossary entry.

Banks and finance companies that lend for cars are regulated by the Monetary Authority of Singapore. That is why every bank caps your loan at 70% of the purchase price when the car's Open Market Value is S$20,000 or below, and at 60% when the OMV is higher, with a maximum tenure of seven years. These motor vehicle loan rules have applied since 2016.
Car dealers are not financial institutions, so MAS does not regulate their in-house schemes. In a 2025 Parliamentary reply, MAS confirmed dealers fall outside its motor vehicle loan rules and warned that unregulated schemes carry higher risks, including hidden charges and bigger losses if you default. The borrowing caps, the standardised disclosures and the consumer protections you get from a bank simply do not bind a dealer. For the underlying terms, see our entries on Open Market Value and the loan-to-value ratio.
A bank car loan counts towards your Total Debt Servicing Ratio, the rule that caps your total monthly debt repayments at 55% of gross income. An in-house loan does not, because the dealer isn't bound by the framework. To a buyer eyeing a property, that looks like free borrowing capacity: take the in-house car loan and your mortgage application stays clean.
That is exactly why it is dangerous. The TDSR exists to stop you over-borrowing, and stepping around it doesn't make the debt disappear, it just hides it from the next lender. If you stretch a car and a home loan at the same time, a single income shock can tip both into trouble. Before treating the loophole as a win, run your numbers through our personal budget calculator to see whether the combined repayments actually fit. The concept itself is worth understanding in full via our TDSR glossary entry.
Because dealers aren't bound by the 60/70% cap, some advertise schemes with little or no cash downpayment. The mechanics behind a few of these are what worried the regulator. MAS flagged a practice where a dealer inflates the invoice so a bank's percentage-based loan covers almost the whole real cost: if a car genuinely costs S$120,000 but the invoice reads S$170,000, a 70% loan of about S$119,000 leaves the buyer paying close to nothing upfront.
The problem is you have borrowed against a price the car never had. The day you drive off, you owe more than the car is worth, so you are in negative equity from the start. Sell or write off the car early and you still owe the gap. A low or zero downpayment is a financing red flag, not a discount. Run the genuine ownership cost first with our car cost calculator so you know the real price before any dealer maths is applied.
In-house loans layer on charges that banks usually don't. Industry write-ups put dealer administrative fees at around S$500 to S$600, rising on premium cars to roughly 1% of the financed amount or about S$1,200, whichever is higher. None of that shows up in the flat rate.
Watch the balloon, or deferred, payment scheme too. Here the car's expected PARF rebate is carved out of the loan upfront, which lowers your monthly instalment but leaves a large lump sum due at the end. It can suit a buyer with a clear plan to scrap the car, but if you can't fund the final payment, you've simply pushed the problem down the road. And because the interest is flat, paying the loan off early saves far less than you'd hope, since most of the interest is baked in from day one and an early settlement fee (commonly around 1% of the outstanding balance) often applies.
The flat-rate gap sounds small until you annualise it across a full tenure. Flat-rate interest is just loan amount times rate times years, so the difference scales directly with how long you borrow.
Take a S$60,000 loan over seven years, a realistic figure for a mid-life used car. At a bank's 2.98% flat rate you pay S$12,516 in interest. At an in-house 4.8% flat rate you pay S$20,160. That is S$7,644 more for the same car and the same tenure, before any admin fees or price markup. Push the in-house rate to 6% and the interest hits S$25,200, nearly double the bank figure.
For most buyers with a clean credit record, a bank car loan is cheaper, more transparent and better protected. In-house financing earns its place in a narrow set of cases. If you're buying an older used car the banks won't touch, a dealer scheme may be your only route to financing. If your credit history has dents that would see a bank reject you or price the loan punitively, a dealer that skips the credit check can get you on the road.
Even then, treat the dealer quote as a starting point, not the only option. Get a bank's EIR in writing first, then ask the dealer to match it rather than the flat rate. Read the full terms, ask what fees apply and what happens if you miss a payment, and never sign a zero-downpayment scheme without understanding the inflated-price mechanism behind it. If you're weighing the loan against the bigger picture of running a car, our guide to what a car really costs in Singapore puts the financing in context.
Usually no. As of June 2026, in-house dealer schemes commonly charge a flat rate of 3.5% to 6% per annum, against around 2.78% for new and 2.98% for used cars at the banks. Even a teaser rate as low as 1.68% is often offset by an inflated car price or extra fees, so the effective interest rate ends up higher. Compare every offer on EIR, not the flat rate.
No. Because car dealers are not regulated by MAS, their in-house loans sit outside the Total Debt Servicing Ratio framework, so they don't reduce the home loan you qualify for. That looks attractive, but it is a double-edged sword: the debt is still real, and bypassing the 55% cap makes it easy to over-borrow on a car and a mortgage at the same time.
No. Car dealers are not financial institutions, so MAS does not regulate their in-house financing, and the 60/70% loan-to-value cap and seven-year tenure limit do not apply to them. In a 2025 Parliamentary reply, MAS warned that unregulated schemes carry higher risks, including hidden charges and larger losses for borrowers who default, so consumer protection is weaker than with a bank.
Some dealers advertise schemes needing little or no cash upfront. MAS flagged a method where the invoice is inflated above the real price so a bank's percentage-based loan covers almost the entire genuine cost, leaving the buyer paying close to nothing. The danger is negative equity from day one: you owe more than the car is worth, and selling or writing it off early still leaves you with the shortfall.
