Does your lender allow biweekly mortgage payments?
Some mortgage servicers accept biweekly payments and apply each half-payment as it arrives, some only accept full monthly payments, and some offer a biweekly program that may come with a fee. The only way to know is to ask your servicer directly. If they do not support biweekly payments, you can usually get most of the same benefit by sending extra money marked for principal.
This guide covers what to ask, what to watch for with third-party biweekly services, and how to make sure extra money actually reduces your loan.
Start with your servicer, not your original lender
The company you send payments to is your loan servicer. It may not be the lender that made the loan, because loans and servicing rights are often transferred. Your servicer’s rules decide how payments are handled, so check your latest statement or online account for their name and contact details.
Look for a section on payment options, automatic payments, or extra principal payments. If the answer is not clear, call or send a secure message and ask the questions below.
Questions to ask
- Do you accept half-payments every two weeks? Ask whether each half-payment is applied to the loan when received, or held until a full monthly payment has arrived.
- Is there a fee? Ask about any setup fee, per-payment fee, or charge for an official biweekly program.
- How are extra payments applied? Ask whether money above your regular payment goes to principal automatically, or whether you need to label it as a principal payment.
- Is there a prepayment penalty? Your loan documents will say whether paying ahead triggers any charge. Ask the servicer to confirm.
- Will paying extra change my required payment? On most fixed-rate loans, extra principal shortens the loan rather than lowering the monthly amount, but confirm how your servicer treats it.
Why it matters if payments are held
If your servicer holds each half-payment in a suspense or unapplied account until the other half arrives, your loan is still paid monthly. You get no timing benefit, and until enough money has built up, the extra does not reduce your balance. In some cases the extra amount is applied only once a year, which behaves like making one extra monthly payment annually.
That still saves money, but less than a true biweekly plan. Our calculator includes both approaches, so you can see how much the difference is worth on your own loan before you decide whether it is worth paying for a program.
Be careful with third-party biweekly services
Some companies offer to manage biweekly payments for you. They collect half of your payment every two weeks, then pay your servicer. Before you sign up for any of these services, read the terms closely:
- Fees. Setup fees and per-payment fees reduce your savings. Compare any fee with the savings figure from the calculator, and remember the fee is paid whether or not you keep the plan for the full term.
- When your money is sent. A service may hold your payments and forward them monthly or once a year. Your money may sit with them rather than reducing your loan.
- Who is responsible if a payment is late. Your servicer only sees what arrives from the service. If a payment is forwarded late, it is still your loan.
- Whether you need them at all. You can usually send extra principal yourself at no cost, which can produce similar savings.
How to pay extra principal yourself
If biweekly payments are not available, or not worth a fee, you can add extra money yourself. Common choices are one extra monthly payment a year, or one-twelfth of a payment added to each monthly payment. When you pay, use the servicer’s option for an additional principal payment, or include a note that the extra is for principal only. Then check your next statement to confirm the balance dropped by the extra amount.
Worked example: what the payment method is worth
For example, suppose you have a hypothetical $250,000, 30-year fixed-rate loan at 6%, with a monthly payment of $1,498.88 and total interest of $289,593.37 if paid monthly for the full term. Using the same math as our calculator:
| How payments are applied | Interest saved | Time saved |
|---|---|---|
| Each $749.44 half-payment applied when it arrives (true biweekly) | $62,029.08 | 65 months |
| Extra applied once a year (one extra monthly payment) | $59,102.40 | 63 months |
If a half-payment is simply held and applied as one regular monthly payment, with no extra, there is no saving at all compared with the $1,498.88 monthly schedule. If a service charges fees, subtract them from these figures to see what the plan would really be worth to you.
Common questions
Will my servicer think a half-payment is late?
It can happen if half-payments are not part of an approved arrangement. Until your servicer confirms in writing how half-payments are handled, keep paying at least the full monthly amount by the due date.
Is a biweekly program from my own servicer better than a third-party one?
It may be simpler, because there is no middle company handling your money, but check for fees either way and confirm when payments are applied.
The takeaway
Ask your servicer whether half-payments are applied when they arrive, whether there is a fee, and how to send extra money to principal. Be cautious with third-party biweekly services: their fees and payment timing can cut into the savings, and you can usually pay extra principal yourself for free. Whatever method you use, confirm on your statements that the extra money reduced your balance.
