Frequently Asked Questions about Mortgage & Loan Amortization Calculator

What is the difference between Equal Principal and Equal Installment?

Under 'Equal Principal' (Declining Balance), your principal payment is constant every month while interest decreases over time, making total monthly payments drop over time. Under 'Equal Installment' (EMI), your total monthly payment remains constant throughout the loan.

How does the Early Payoff calculator work?

When you pay extra principal each month, the loan principal reduces faster, resulting in lower interest charges in subsequent months and allowing you to pay off the loan years earlier.
