Amortization Calculator
Generate loan payment amortization tables dynamically. View monthly interest and principal breakdowns.
Loan Parameters
For long-term fixed loans, interest charges represent a significant markup on top of the original borrowed principal. Prepayments lower this ratio over time.

Understanding the Loan Amortization Schedule
An amortization schedule outlines each periodic payment on a fixed-rate loan over its entire lifespan. Every payment goes toward both interest charges (fee paid to the lender) and principal balance (the actual amount borrowed). By analyzing these curves, borrowers can see the precise "tipping point" where payments clear more principal than interest.
The Impact of Making Extra Payments
Prepayments represent extra money paid directly toward the loan's outstanding principal balance. By lowering the principal balance early, you decrease the amount of interest calculated in all future periods, accelerating your payoff date and saving thousands in interest costs.
