Car Loan Rates Singapore: Compare Flat Rates, Fees and EIR
Compare a car loan on the same borrowed amount, repayment term and fee basis. A low flat-rate headline can lose to a higher rate once compulsory fees are included. EIR helps compare the timing of payments; total dollars and cash reserves still matter.
Collect a dated written quote and repayment schedule first. Use the car loan calculator for a whole purchase or the COE funding calculator for a separate COE amount. If COE is included in the car price, do not fund or count it twice.
Read the rate definition before calculating
Flat rate: interest uses original principal for the full term. For S$100,000 at 2.28% flat over five years, interest is S$100,000 × 2.28% × 5 = S$11,400. Repayments total S$111,400; divide by 60 to get the unrounded monthly instalment.
Reducing balance: interest uses the unpaid balance. A nominal annual rate charged monthly uses annual rate ÷ 12. A compounded annual effective rate uses (1 + annual rate)1/12 − 1. Confirm the convention behind an APR or EIR label with the lender.
Fee-inclusive annual EIR: treat required upfront loan fees as reducing net funding; solve the monthly rate that discounts instalments back to that funding, then annualise as (1 + monthly rate)12 − 1. The examples below use equal monthly payments starting one month after funding. Compare quotes using the same convention and included charges. EIR is not an estimate of early-exit cost.
Replace a generic market range with dated comparable quotes
An advertised rate can depend on lender, vehicle, amount, term, promotions and required add-ons. This page provides hypothetical arithmetic, not a live rate table. Ask each lender to complete the same worksheet:
- Identity and scope: lender, agreement type, quote date, expiry and whether it finances a purchase or COE renewal.
- Funding: purchase price, cash contribution, principal actually advanced, and any compulsory charges paid separately or added to the loan.
- Repayments: rate definition, fee basis, number of instalments, first payment date, monthly amount and any final balloon.
- Cost: sum of payments, interest, fees, annual EIR definition and which charges that EIR includes.
- Exit: written settlement illustrations for the dates you might sell, including rebates, notice, redemption and administrative charges.
Compare mandatory insurance or add-ons on the same cover and price basis. If an offer changes the car's cash price or removes a discount, include that difference in the purchase decision as well as the loan fee comparison.
Worked example: the lower rate costs S$500 more
Both hypothetical offers advance S$100,000 for 60 equal monthly payments. Fees are paid upfront; there is no balloon or early exit. Displayed instalments are rounded, while totals use the unrounded schedule.
| Quote component | Offer A | Offer B |
|---|---|---|
| Flat annual rate | 2.28% | 2.18% |
| Upfront loan fee | S$0 | S$1,000 |
| Monthly instalment | S$1,856.67 | S$1,848.33 |
| Full-term interest | S$11,400 | S$10,900 |
| Repayments + fees | S$111,400 | S$111,900 |
| Fee-inclusive annual EIR | 4.42% | 4.66% |
B saves S$500 interest but charges S$1,000 more upfront: it costs S$500 more across the full term. Its monthly payment is lower by S$8.33, but its fee-inclusive EIR is higher. Reproduce this in the COE calculator with amount S$100,000, contribution 0%, five years, flat rate and the stated fee; this is an arithmetic illustration, not evidence that zero contribution is permitted.
Lower monthly payment can still mean more total interest
Keep S$100,000 principal and 2.28% flat fixed, with no fees. Extending from five to seven years changes the figures below:
| Measure | 5 years | 7 years |
|---|---|---|
| Number of instalments | 60 | 84 |
| Monthly instalment | S$1,856.67 | S$1,380.48 |
| Total interest | S$11,400 | S$15,960 |
| Total repayments | S$111,400 | S$115,960 |
| Annual EIR | 4.42% | 4.38% |
Monthly payments fall S$476.19, while interest rises S$4,560. The annualised EIR falls slightly because payment timing changes. That does not make the seven-year loan cheaper in dollars. Choose a term that fits both cash capacity and the ownership plan.
Separate purchase rules, lender approval and exit debt
For financial-institution motor vehicle purchase loans, the MAS framework sets maximum loan-to-value at 70% when applicable OMV is S$20,000 or less, and 60% above S$20,000, with a maximum seven-year tenure. The purchase-price basis includes taxes and COE; OMV determines the band, not the financed purchase price. Lenders can approve less. See MAS's published framework.
MOT's 4 February 2026 statement confirms that financial-institution vehicle loans follow MAS restrictions and warns that alternative dealer financing falls outside MAS regulation. Identify the contract and lender before treating a dealer's low-downpayment package as equivalent to a bank loan.
A COE renewal funding quote needs its own written eligibility and terms. The COE calculator does not approve a loan or apply purchase-loan caps automatically. Match the repayment end date with the actual COE expiry; confirm whether a further renewal is possible under LTA's renewal rules.
If sale is likely before maturity, compare payments made plus quoted settlement and fees through that date. Do not subtract a guessed pro-rata interest refund from a full-term total. Gross sale proceeds minus settlement can be negative; use the sale and settlement cash worksheet.
Price the cash reserve before choosing financing
Write down the cash contribution, fees and first payment due at collection, then reserve money for insurance, tax, repairs and income disruption. Principal repayment is a cash outflow; interest and fees are financing cost. Your cash contribution belongs in the purchase funding total, not in loan interest.
Paying cash saves future financing charges but reduces liquid reserves. Borrowing preserves some cash while creating fixed payments and a potential settlement gap. An uncertain investment return is not a guaranteed offset to the loan. Compare both routes in the loan-versus-cash decision guide and stress-test the whole monthly car burden.
Four gates before accepting the quote
- Comparable contract: same principal, term, dates, price and included fees; identify any balloon or financed add-on.
- Cost understood: reconcile repayments and charges, calculate EIR consistently, and compare full-term dollars.
- Cash capacity: pay initial cash and routine costs while retaining a household buffer through an income dip.
- Exit funded: obtain dated settlement illustrations and test lower sale proceeds; resolve any loan term beyond COE expiry.
If the quote cannot pass these gates, obtain clarification or reduce the purchase commitment before signing. The full-quote checklist and early-settlement guide provide the next worksheets.
FAQ
Can I double a flat rate to get EIR?
Use the actual cash flows instead. The effective rate depends on payment frequency, term and fees. This guide compounds the solved monthly repayment rate over 12 months; a fixed flat-rate multiplier cannot reproduce every quote.
Is the lowest advertised rate the cheapest loan?
Compare the same amount and term, compulsory fees, repayments and settlement costs at your planned exit. A lower flat rate with a larger fee can cost more overall.
Does a lower instalment mean a lower borrowing cost?
No. Extending the term can reduce monthly payments while increasing total interest. Check both monthly capacity and full-term dollars, then obtain an early-settlement quote if you expect to exit sooner.
Do purchase-loan limits establish COE renewal loan eligibility?
No. Identify the lender, agreement type and purpose. Purchase-loan rules and a COE renewal funding quote are not interchangeable; ask for the applicable requirements and terms in writing.
