How Does the Loan Calculator Work?
This loan calculator estimates the periodic payment required to repay a loan based on the amount borrowed, interest rate and repayment term. It also estimates total interest, borrowing costs and the remaining balance over time.
Loan Payment Formula
For a standard reducing-balance loan, P represents the principal, r represents the interest rate for each payment period and n represents the total number of payments.
Why Make Extra Loan Payments?
Additional principal payments can reduce the outstanding balance faster. Depending on the loan agreement, this can reduce the amount of future interest charged and may shorten the repayment period.
