How to Use the Amortization Calculator
Generate a complete loan payment schedule showing how each payment splits between principal and interest. See how extra payments can save thousands in interest and years off your loan. This complements our mortgage calculator and loan calculator.
Understanding the Schedule
Early payments are mostly interest; later payments are mostly principal. This is why extra payments early in the loan term have the biggest impact on total interest paid.
Extra Payment Strategy
- Even small extra payments add up significantly over time
- Bi-weekly payments (26 half-payments) equal 13 monthly payments per year
- Apply extra payments to principal, not future payments
- Check for prepayment penalties before paying extra
