- • $200 Monthly Extra: Saves $95,000+ and 9-11 years on typical loans
- • Annual Bonuses: Applying tax refunds to principal can save $30,000+ in interest
- • Bi-weekly Payments: Making 26 half-payments yearly saves 4-6 years

Smart Amortization Strategies
Early Payment Power
Extra payments in the first 10 years have 3x more impact than later years. A $200 monthly extra payment can save $80,000+ in interest on a 30-year mortgage.
Bi-Weekly Strategy
Making 26 bi-weekly payments (half your monthly amount) instead of 12 monthly payments reduces loan term by 4-6 years and saves $40,000-60,000 in interest.
Windfall Application
Applying tax refunds, bonuses, or windfalls directly to principal can save $25,000-35,000 in interest. Even one-time $5,000 payments have massive long-term impact.
Rate vs Investment
If your loan rate is below 5%, consider investing extra payments instead. Historical market returns of 7-10% often exceed loan interest rates.
