How prepayments work

Extra principal reduces the outstanding balance immediately, reducing future interest accrual. The schedule shortens unless the lender re-amortizes differently.

Monthly vs annual prepayments

Adding a small monthly amount can rival one large yearly prepayment in total savings; model both for your situation.

Penalties and fees

Some loans charge prepayment penalties. Check your loan contract before making extra payments.

Checklist

  • Check prepayment clauses
  • Model monthly + annual extras
  • Confirm lenderโ€™s re-amortization policy
