Frequently asked questions
How is the monthly payment calculated?
The calculator uses the fixed-annuity formula: payment = principal × monthly rate ÷ (1 − (1 + monthly rate)^−months), keeping the installment constant for the whole term.
Will the results match my bank exactly?
The math is exact for a fixed-payment loan, but banks may add admin fees or insurance, or use a different profit method — always check the bank’s official offer.
What does the amortization schedule show?
For every month it shows how your payment splits between interest and principal. Early payments are mostly interest; over time the principal share grows until the balance reaches zero.
Is the interest simple or compound?
Payments are computed on the remaining monthly balance — the standard method for fixed-installment bank loans.
