Frequently asked questions

How is the monthly payment calculated?

With the standard amortization (EMI) formula M = P·r·(1 + r)ⁿ / ((1 + r)ⁿ − 1), where P is the loan amount, r the monthly interest rate (annual rate ÷ 12) and n the number of monthly payments.

Why is most of the early payment interest?

Interest is charged on the outstanding balance, which is highest at the start. As the balance falls, more of each fixed payment goes to principal.
