Amortization Schedule Calculator
Generate a full month by month amortization schedule for any loan, with a year by year summary.
An amortization schedule lists every payment on a loan. It shows how much goes to interest and how much to principal.
Early payments are mostly interest. The balance tips toward principal over time.
How it works
Each month interest is charged on the remaining balance. The fixed payment covers it and the rest reduces the balance.
The yearly table summarizes the schedule. The full monthly table is below it.
The formula
Principal this month = payment - interest.
Tips
- Find the month where principal first exceeds interest. On a 30 year loan at 6% it is around year 19.
- Use the schedule to see exactly what a lump sum payment would skip.
