How to Think About This Calculation
Understand standard amortization schedules for personal, auto, or student loans.
Core methodology
- 1.Acquire the total principal amount borrowed.
- 2.Convert the annual interest rate to a periodic monthly interest rate.
- 3.Calculate the exact monthly payment that ensures the balance reaches zero at the term limit.
Professional tips
- Making extra principal-only payments early in the loan dramatically reduces total interest costs over time.
- Check for pre-payment penalties before deciding to settle a loan early.
Common pitfalls
- Confusing nominal annual interest rate (APR) with periodic monthly compounding rate.
- Assuming payments are split equally between principal and interest throughout the term.
