The DBS car loan calculator tells you a monthly figure in seconds, but the number only makes sense once you know what feeds it. Three inputs do the heavy lifting: how much you can actually borrow (capped by law at 60% or 70% of the price), the flat interest rate DBS quotes (from around 2.78% p.a. as of June 2026), and the tenure you pick (up to 7 years). Get those right and the calculator output matches what you sign for. Get them wrong and you under-budget the downpayment. This guide walks through each input, shows the maths behind a sample loan, and explains why the effective rate you really pay is almost double the headline.
DBS runs two related tools on its site: a car loan calculator that works backwards from your budget, and a monthly instalment calculator that works forwards from a loan amount. Both need the same three numbers. The loan amount, the flat interest rate, and the repayment period in years.
The trap is the loan amount. People type in the full car price, but Singapore law won't let a bank lend you that much. Your maximum loan is set by the car's Open Market Value, and the rest is a cash downpayment you pay upfront. So before you touch any rate, settle how much you can borrow. Our car cost calculator helps you see the full ownership bill, not just the loan slice.
The borrowing limit isn't DBS policy, it's a Monetary Authority of Singapore rule that every bank and finance company follows. It has been in force since 27 May 2016 and is tied to the car's Open Market Value, which is the value Singapore Customs assesses before taxes.
If the OMV is S$20,000 or below, you can borrow up to 70% of the purchase price. If the OMV is above S$20,000, the cap drops to 60%. Most new mass-market cars in Singapore sit above that OMV line once you factor in current values, so plan for the 60% cap unless you've confirmed otherwise. The remaining 30% to 40% is your cash downpayment. For the definitions behind these terms, see our glossary entries on Open Market Value and the loan-to-value ratio.
| Car's OMV | Max you can borrow | Min cash downpayment | Max tenure |
|---|---|---|---|
| S$20,000 or below | 70% of purchase price | 30% | 7 years |
| Above S$20,000 | 60% of purchase price | 40% | 7 years |
DBS car loans use flat-rate interest, the same as every other bank here. Flat rate charges interest on the full original loan for the entire tenure, even though you're steadily paying the balance down. That's why the rate looks low but costs more than it seems.
The formula is simple. Total interest equals loan amount, times the flat rate, times the number of years. Add that to the loan, divide by the number of months, and you have your instalment.
Say you buy a car priced at S$150,000 with an OMV above S$20,000, so you borrow the 60% maximum of S$90,000 over 7 years at a flat 2.78% p.a.
The flat rate is for marketing. The effective interest rate (EIR) is what you actually pay, because it accounts for the shrinking balance. On a typical DBS car loan a 2.78% flat rate works out to an EIR of roughly 5.19% p.a. as of June 2026, and the greener 2.48% flat rate sits around 4.65% EIR.
Always compare loans on EIR, never flat rate, since the gap is consistent across banks and the flat figure flatters every lender equally. We break the concept down in our EIR glossary entry. The same logic applies to almost any bank loan in Singapore.
| Lender | Flat rate p.a. | EIR p.a. | Max tenure |
|---|---|---|---|
| DBS (petrol/diesel) | from 2.78% | around 5.19% | 7 years |
| DBS Green Car Loan (EV/hybrid) | from 2.48% | around 4.65% | 7 years |
| OCBC | from 2.78% | around 5.19% | 7 years |
| UOB | from 2.78% | around 5.19% | 7 years |
| Hong Leong (used car) | from 3.08% | around 6.68% | 7 years |
Seven years is the legal ceiling, but used cars carry an extra rule: the loan must end before the car turns 10 years old. Buy a 5-year-old used car and your maximum tenure is 5 years, not 7. The DBS calculator won't stop you entering 7, so check the car's age yourself.
DBS also runs a Green Car Loan for electric and hybrid vehicles at a lower flat rate (from 2.48% p.a. as of June 2026), often paired with a small cash rebate. If you're weighing a longer tenure against a shorter one, a longer term lowers the monthly figure but raises total interest, since flat-rate interest scales directly with the number of years. Run both through the calculator before deciding.
The instalment the calculator shows is the loan only. Annual road tax, insurance, parking, ERP, fuel or charging, and servicing aren't in it, and together they often rival the loan repayment. Build the full picture so the monthly figure you commit to is the real one.
It's also worth comparing the dealer's in-house financing against DBS directly. Dealers sometimes bundle a higher rate into an attractive sticker price. Get the DBS quote, run it through the calculator, then ask the dealer to match the EIR rather than the flat rate.

It uses the flat rate you enter, which for DBS starts around 2.78% per annum for petrol and diesel cars and from 2.48% for the Green Car Loan, both as of June 2026. The flat rate translates to a higher effective rate (EIR) of roughly 5.19% and 4.65% respectively, since interest is charged on the full original loan throughout the tenure.
DBS follows the MAS cap. You can borrow up to 70% of the purchase price if the car's Open Market Value is S$20,000 or below, and up to 60% if the OMV is above S$20,000. The rest is a cash downpayment, so on most new cars expect to pay 40% upfront. The maximum tenure is 7 years.
No. The calculator shows only the loan instalment. Road tax, insurance, parking, ERP, fuel or charging, and maintenance are separate and can add several hundred dollars a month. Use a full car cost calculator alongside the loan figure to budget for the real monthly outlay.
You can, but the savings are limited because car loans use flat-rate interest computed on the full loan upfront. DBS applies an early redemption fee, commonly around 1% of the outstanding balance, alongside an interest rebate adjustment. Check the exact figures in your loan agreement before settling early, as the net benefit is often smaller than borrowers expect.
