How Extra Payments Work
What are extra payments? Additional amounts beyond your required monthly payment that go directly to reducing your loan principal, saving you interest.
Impact of Extra Payments:
- Reduce total interest paid over life of loan
- Shorten loan term (pay off years earlier)
- Build equity faster
- Save thousands to tens of thousands in interest
Common Extra Payment Strategies:
- Round Up: Pay $2,000 instead of $1,897.22
- 13th Payment: Make one extra full payment per year
- Biweekly Payments: Pay half your monthly payment every 2 weeks (26 payments = 13 months)
- Windfall Payments: Apply tax refunds, bonuses, or gifts to principal
- Percentage Increase: Pay 10-20% more each month
Example: On a $300k 30-year loan at 6.5%, paying just $200 extra per month saves $94,000 in interest and pays off the loan 7 years earlier.
