Questions about Loan Calculator
What calculation method does this tool use?
The French amortization system, the most common for personal and mortgage loans, where the monthly payment stays fixed for the whole term.
Why is the payment fixed but the interest changes each month?
Because early on you pay more interest and less principal, and as the balance drops, each payment allocates more to principal and less to interest, even though the total payment amount doesn't change.
Can I see the breakdown of each payment?
Yes, the amortization table shows, payment by payment, how much goes to principal and how much to interest.
Is this simulation an actual loan?
No, it's just a reference simulation — the real terms of a loan (fees, insurance, variable rates) depend on each financial institution.
