1. Enter loan amount (principal). 2. Enter annual interest rate and term in years. 3. Click Calculate amortization. 4. Review monthly payment, total interest, and the period-by-period schedule.
Worked example
Example: a $300,000 loan at 6% for 30 years gives a fixed monthly payment near $1,799 with early payments mostly interest and later payments mostly principal.
How it works
Builds a full amortization schedule from loan amount, annual interest rate, and term. Shows monthly payment plus principal and interest split for each period.
Limitations
Schedule assumes fixed rate and on-time payments. Extra principal, escrow changes, and ARM adjustments are not modeled.
Privacy and file handling
Your data stays on your device and is not uploaded.
Formula or method
Monthly payment uses standard fixed-rate amortization; each period applies interest to the remaining balance and allocates the remainder to principal.
