How to Use This Tool
Enter your loan details including amount, interest rate, and term. Specify the extra payment amount and when you plan to start prepaying. Choose a prepayment method—monthly, lump sum, or annual—and click Calculate to see how much time and interest you can save.
Formula and Logic
This calculator uses the standard amortization formula to compute monthly payments. It then simulates each payment period, applying extra payments according to your selected method. The logic tracks balance reduction, interest accrual, and total costs to determine the new payoff date and savings.
Practical Notes
- Local market variation: Prepayment benefits can differ based on regional interest rates and property values.
- Closing cost components: Consider refinancing costs if switching to a lower rate instead of prepaying.
- Rental yield benchmarks: For investors, compare prepayment savings against potential rental income growth.
- Financing options: Explore bi-weekly payments or recasting loans as alternatives to lump-sum prepayments.
