How this is calculated
Extras are applied to principal after the scheduled payment. Each saved month removes one period of interest accrual and shortens the schedule.
Frequently asked questions
- Will my lender apply extras to principal?
- Most lenders will, but some require explicit instruction. Always check with your lender that extra amounts go to principal.
