This calculator estimates equal-payment repayment from the annual rate and term you enter. Actual rates, fees, and eligibility vary by product and borrower; check lender documentation and J-FLEC learning resources.
02
Down-payment effect
A larger entered down payment or trade-in reduces the financed principal, monthly estimate, and total-interest estimate. The calculator does not predict approval.
03
Comparing terms
With the same principal and rate assumption, a longer term generally lowers the scheduled monthly amount but can increase total interest. Confirm available terms with the lender.
04
Repayment and bonus months
The regular payment uses fixed-payment amortization over the entered term. An optional bonus-month amount is applied to principal in its scheduled month to show a possible earlier payoff.
05
Related Costs: Auto Tax, Insurance & Garage Certificate
The loan amount usually covers only the vehicle price. You should budget separately for automobile tax (jidousha-zei), environmental performance tax, weight tax, compulsory insurance (jibaiseki), and the garage certificate (shako shoumei).
06
Early Repayment (Kuriage Hensai)
If you have spare funds, early repayment (kuriage hensai) can reduce remaining interest costs. Some dealer loan products may charge an early-repayment fee, so check your contract terms first.
Frequently asked questions
How is the monthly payment calculated?
The loan amount (car price minus down payment and trade-in value) is amortized using the standard equal principal-and-interest loan formula.
What happens if I increase the down payment?
It lowers the principal used by this estimate, reducing the monthly amount and total-interest estimate. It does not predict approval.
What should I compare between products?
Check the effective annual rate, fees, ownership, early-repayment conditions, bonus-payment rules, and total repayment in writing.
