Methodology
This section explains the calculation logic, assumptions, and source material used to make the result more trustworthy and easier to verify.
EMI = P × r × (1+r)^n ÷ ((1+r)^n − 1)
P = principal · r = monthly rate (annual ÷ 12) · n = total months
For credit score markets: effective rate = base rate ± score tier adjustment.
These five markets use formal credit bureaus. The calculator applies a rate adjustment based on your score tier — verified against each bureau's published ranges.

EMI (Equated Monthly Instalment) is the fixed monthly payment you make to repay a loan. Each payment covers both principal and interest. Early instalments are weighted more towards interest; the principal share grows each month as the outstanding balance reduces.
EMI = P × r × (1+r)^n ÷ ((1+r)^n − 1), where P is the principal, r is the monthly interest rate (annual rate ÷ 12), and n is the number of monthly payments. This calculator uses the reducing balance method — the same method used by most regulated lenders.
Home loan, car loan, personal loan, and SME/business loan. Each type loads a typical rate range as a starting point — you can override with your lender's actual rate.

USA (FICO), Canada (Equifax/TransUnion), UK (Experian), Australia (Equifax AU), and Singapore (CBS). The calculator adjusts the effective rate based on your score tier — lower scores attract a rate premium, higher scores a discount.
The amortization schedule shows the month-by-month breakdown of each payment — how much goes to interest and how much reduces the principal. It also shows the remaining balance after each payment.
Flat rate calculates interest on the original principal for the entire tenure. Reducing balance calculates interest only on the outstanding amount each month. Reducing balance is significantly cheaper. This calculator uses reducing balance — verify which method your lender uses before signing.
