Common Questions & Guidance
Frequently asked questions regarding Amortization Calculator.
What is amortization?
Amortization is the process of spreading out a loan into a series of equal periodic payments. Although the payment stays the same, the ratio of interest to principal shifts, with interest dominating early payments and principal dominating later ones.
How does adding extra payments impact amortization?
Extra payments go directly to the principal balance. This reduces the total outstanding balance, causing less interest to accrue in subsequent months and shifting the amortization curve in your favor.
