Frequently Asked Questions

How does paying extra principal reduce my mortgage term?

Extra payments reduce your unpaid principal balance directly. Because monthly mortgage interest is calculated strictly on remaining principal, lowering the balance immediately reduces the future interest charges.

Is it better to pay extra monthly or one lump sum annually?

Paying extra monthly usually saves more interest because the principal balance drops 12 times a year rather than waiting for an annual bonus payment.
