FAQ
How is the monthly payment calculated?
With monthly rate r (annual rate ÷ 12) and n payments: loan × r × (1 + r)^n ÷ ((1 + r)^n − 1). At 0% it is loan ÷ n. The calculation uses exact decimals instead of binary floating point and rounds to the smallest currency unit.
Why is the final payment different?
The payment and each month's interest are rounded to the cent (or yen), and the small differences add up. The final payment absorbs them so the balance ends at exactly 0.
Can it handle prepayments or extra payments?
No. It calculates level monthly payments only. Prepayments, extra or balloon payments, equal-principal repayment and rate changes are not included.
Notes & limitations
- What you enter is processed only on this page and is not sent to YUCTS servers.
- Prepayments (partial or full), extra payments, fees, guarantee charges, insurance and rate changes are not included.
- Lenders may round differently or charge interest by actual days, so real payments can differ slightly. Your loan contract and the lender's schedule are authoritative.
- The starting rate is only an example, not a current market rate.
