Frequently Asked Questions

What is an amortization schedule?

An amortization schedule is a complete table of periodic loan payments showing the breakdown of each payment into principal and interest. It also shows the remaining balance after each payment, giving you a full picture of how your loan is paid off over time.

How do extra payments affect amortization?

Extra principal payments reduce your remaining balance immediately, which cuts the interest charged in all future periods. A single extra $200 payment in year 1 of a 30-year mortgage can save more than $1,000 in total interest because the savings compound over the remaining term.

How does bi-weekly payment save money?

Bi-weekly payments mean 26 half-payments per year, which equals 13 full monthly payments instead of 12. That one extra payment per year goes entirely to principal, reducing your balance faster and saving significant interest.

How many years can bi-weekly payments save?

On a typical 30-year mortgage, bi-weekly payments can shave off approximately 4-6 years and save tens of thousands in interest. The exact savings depend on your loan amount and interest rate.
