How the Biweekly Hack Works
Instead of making 12 full monthly payments per year, a biweekly mortgage schedule involves paying exactly half of your monthly payment every two weeks. Because there are 52 weeks in a calendar year, this results in 26 half-payments.
26 half-payments equals exactly 13 full monthly payments. By simply matching your mortgage obligations to your biweekly paycheck, you are secretly submitting an entire month of extra principal payments to the lender every single year without feeling the burden.
Applying an extra principal payment every year drastically reduces the underlying compounding interest. It guarantees to shave multiple years off your loan term and often averts tens of thousands of dollars in interest charges.
Frequently Asked Questions
Most lenders legally permit biweekly payments, but some may try to charge you 'setup fees' for automatic third-party biweekly processors. Never pay for this! You can replicate the exact same math manually by simply making one extra principal-only payment each year.
No. Your property tax and insurance escrows will simply build a larger cushion. The critical math is ensuring your lender applies the extra funds directly to your Principal Balance, not to future interest.
