Beyond the monthly bill: total cost of borrowing
- Financed amount = vehicle price minus down payment (and trade-in, if applicable).
- APR sets how expensive the loan is per year.
- Term length multiplies interest exposure: longer terms often reduce the payment but increase lifetime interest.
- Compare reducing balance vs flat in the main car-loan tool when a promotion uses flat wording.
Sample: 20% down, 60 months
- THB 600,000 car, THB 120,000 down → THB 480,000 financed.
- 3% APR, 60 months → about THB 8,500 - 9,000 / month (illustrative).
- Switching to 72 months with the same inputs usually lowers the monthly number—check whether the extra interest fits your plan.
Cheap payment ≠ automatically a good deal
- Promotional rates may come with shorter terms, specific stock, or bundled fees.
- Stretching the term reduces monthly stress but can increase total interest paid.
- Variable income households may want a lower payment ratio even if the “standard” table looks OK.
