Car finance rates in Thailand (2026)
Car loans in Thailand typically run about flat 2.5–4.5% p.a. (about 5–9% reducing balance). Rates are usually quoted as a flat rate, so the effective reducing-balance cost is higher.
These are reference figures for 2026 - always confirm the current rate and the effective (reducing-balance) APR with the lender before you commit.
Where to get a car loan in Thailand
Commonly used providers include Toyota Leasing, Siam Kubota, KBank, SCB and Krungthai. Rates and terms vary by lender, your credit profile, and whether you are buying new or used - it pays to compare at least two or three offers.
Deposit and loan term
Deposit requirements vary by lender. Loan terms run up to about 84 months. A bigger deposit and a shorter term both cut the total interest you pay - use the calculator above to see the trade-off for your own numbers.
Worked example
For every ฿100,000 financed at 4.50% over 5 years:
- Monthly installment: ฿1,864
- Total repaid: ฿111,858
- Total interest: ฿11,858
Scale to your financed amount, and remember a bigger deposit and shorter term lower the total interest.
How to pay less interest on your car loan
- Put down a larger deposit - it reduces both the monthly payment and the total interest.
- Pick the shortest term you can comfortably afford; a longer term lowers the monthly cost but raises the total.
- Compare the effective reducing-balance rate, not a headline flat rate - a flat rate looks cheaper than it really is.
- A stronger credit profile usually earns a lower rate, so it is worth checking before you apply.
