What is a Biweekly Mortgage Payment?

Biweekly mortgage payments involve making half your monthly payment every two weeks. Since there are 52 weeks in a year, you make 26 half-payments (equivalent to 13 full monthly payments) instead of 12.

This simple change means you make one extra monthly payment per year, which can shave years off your mortgage and save tens of thousands in interest—all without feeling like you're paying more.

Why Biweekly Payments Work

The magic is in that extra payment. Here's what happens:

  • 12 Monthly Payments: 12 Ă— monthly amount per year.
  • 26 Biweekly Payments: 26 Ă— half-monthly amount = 13 monthly equivalents.
  • Result: One full extra payment per year goes straight to principal.

That extra principal payment compounds over time, dramatically reducing your balance and the interest calculated on it.

Who Uses Biweekly Payments?

  • Biweekly Paid Workers – payments align with paycheck schedule.
  • Early Payoff Seekers – wanting to eliminate mortgage debt faster.
  • Interest Savers – looking to reduce total interest paid.
  • Budget Simplifiers – prefer smaller, more frequent payments.
  • Equity Builders – wanting to build home equity faster.

Setting Up Biweekly Payments

  • Check if your lender offers a biweekly payment program.
  • Ask about fees—some charge setup or per-payment fees.
  • Alternative: Make one extra principal payment yourself each year.
  • Or: Divide your monthly payment by 12 and add that to each payment.
  • Ensure extra payments go to principal, not escrow or future payments.

Frequently Asked Questions

How much can I save with biweekly payments?
On a $350,000, 30-year mortgage at 6.5%, biweekly payments save about $90,000 in interest and pay off the loan 5+ years early. Savings increase with larger loans, higher rates, and longer terms.
Are there fees for biweekly payment programs?
Some lenders charge setup fees ($200-400) and per-payment fees ($2-5). Do the math—fees can eat into savings. Consider DIY alternatives like making one extra payment per year yourself.
Do biweekly payments improve my credit score?
Not directly. Credit scores reflect payment history, not payment frequency. However, faster payoff reduces debt-to-income ratio and eliminates a major obligation, which indirectly helps creditworthiness.
Can I set up biweekly payments myself?
Yes! Options: 1) Make half payments every two weeks if your lender allows. 2) Make one extra principal payment annually. 3) Add 1/12 of your payment to each monthly payment. All achieve similar results.
What if my lender doesn't offer biweekly payments?
Use the DIY approach: Calculate your monthly payment, divide by 12, and add that amount to each payment. Example: $2,000/month Ă· 12 = $167. Pay $2,167 monthly. Same result, no fees.
Should I pay biweekly or just make one extra payment per year?
Mathematically similar. Biweekly spreads the extra payment throughout the year, slightly reducing interest. One annual extra payment is simpler. Choose based on your discipline and lender options.
Do biweekly payments reduce my monthly payment?
No. Your contractual monthly payment stays the same. Biweekly just means you pay half that amount every two weeks. The "extra" 26th payment goes toward principal reduction.
Can I switch back to monthly payments later?
Usually yes, though some lender programs have commitments. DIY approaches (self-managed extra payments) offer maximum flexibility—you control when and how much extra to pay.
When should I start biweekly payments?
The sooner the better. Starting at loan origination maximizes savings. Starting later still helps but with less total impact. Even beginning 5 years into a 30-year loan can save years and thousands.
Are biweekly payments worth it for short-term loans?
Less dramatic on 15-year loans but still beneficial. The biggest impact is on 30-year mortgages where compound interest has decades to work. Even then, shaving 1-2 years off a 15-year loan saves significant interest.
Can I combine biweekly payments with extra principal payments?
Absolutely! This is a powerful combination. Biweekly gives you the base acceleration, and additional principal payments turbocharge it. Even $50-100 extra monthly with biweekly payments creates substantial savings.
Do all lenders apply biweekly payments immediately?
Not always. Some hold biweekly payments until the full monthly amount is received, negating the benefit. Ensure your lender applies payments as received or use the DIY approach for guaranteed results.
