What is Amortization Schedule?
An amortization schedule is a structured plan that details each payment over time. It shows principal paid interest charged remaining balance and cumulative totals. Schedules help borrowers understand repayment progress evaluate costs make informed adjustments and track the impact of extra payments. Clear tables reveal how loans decline monthly and when payoff occurs. This guidance improves budgeting and financial decisions.

Frequently Asked Questions
1) How are monthly payments calculated?

The standard formula uses the monthly rate and total number of months to produce a fully amortizing payment that reduces the balance to zero at term.

2) Can I enter a custom payment?

Yes you can override the monthly payment. If the amount is too low to cover interest the calculator will request a higher value.

3) When do recurring extras start?

Recurring extras begin at the month number you select and continue every month thereafter until the loan is paid off.

4) How is one time extra handled?

The one time extra is applied entirely to principal in the selected month which shortens the term and reduces total interest.

5) Why does the last payment differ?

The last payment is adjusted so the remaining balance reaches zero which may make it smaller than the standard payment.

6) What if the interest rate is zero?

If the rate is zero the payment equals principal divided by months and every dollar goes to principal.

7) Why do totals use cents rounding?

Lenders work in cents so each month interest and principal are rounded to two decimals which can slightly adjust the final month.

8) Can I export the schedule?

Yes use the Export Schedule as CSV button to download a spreadsheet friendly file of the entire amortization table.
