Early Repayment Calculator Guide
This calculator helps you evaluate the impact of making an early lump-sum payment on your loan. Enter your original loan details and the amount you plan to prepay to see how much interest you can save.
Two repayment methods are available: "Reduce Term" keeps your monthly payment the same but shortens the loan duration, while "Reduce Payment" keeps the original term but lowers your monthly payment.
Early Repayment Calculation Formula
Reduce Term Mode: 1. Calculate remaining principal based on payments made 2. New Principal = Remaining Principal - Early Payment Amount 3. Keep original monthly payment, calculate new term 4. New Total Interest = Monthly Payment × New Term - New Principal 5. Interest Saved = Original Total Interest - New Total Interest 6. Years Saved = Original Remaining Term - New Term Reduce Payment Mode: 1. Calculate remaining principal 2. New Principal = Remaining Principal - Early Payment Amount 3. Keep original remaining term, recalculate monthly payment 4. New Monthly Payment = New Principal × r × (1+r)^n / [(1+r)^n - 1] 5. Interest Saved = Original Total Interest - New Total Interest
