Could biweekly mortgage payments save you money?

Paying off your mortgage early can save you thousands in interest payments and cancel your debt years ahead of schedule. One of the simplest ways to pay down your mortgage sooner is by making biweekly or bimonthly mortgage payments rather than a standard monthly payment. Biweekly and bimonthly payment plans differ slightly, but both can help you build equity faster while paying off your mortgage debt earlier.

With a bimonthly program, your mortgage payment is divided into two and applied twice a month. For example, you might make your payments on the 1st and 15th of each month, for 24 total payments each year.

A biweekly mortgage splits a monthly mortgage payment into 26 equal installments that are made every other week on a set day, such as a Friday. Because most months have more than four weeks, twice a year, you’ll make three payments in a calendar month instead of two (for example, when a month has five Fridays). Making 26 payments a year equals making 13 monthly payments instead of 12.

Although both result in more frequent payments, only biweekly mortgages cut the loan term and substantially reduce the amount of interest paid. Bimonthly payments provide minimal interest savings and do not shorten the loan term.

Bimonthly mortgage payments work one of two ways:

A biweekly mortgage also splits your monthly mortgage payments in half, but applies them every other week. That works out to 26 payments a year, equal to 13 monthly payments. That extra payment reduces the term of the loan and the total interest you pay on it.

Like bimonthly payments, making installments biweekly can help your cash flow by breaking up your payment into two smaller chunks, rather than taking the full amount at once. But this method requires planning, since there will be two months when you’ll have to make three payments. Depending on how often you’re paid, a third payment could affect your budget.

Another benefit to paying biweekly or bimonthly is that you may not have to get a new loan. Some banks and mortgage lenders allow you to convert your monthly installment to biweekly payments, although there may be enrollment and transaction fees. 

Biweekly mortgage payments offer the advantage of paying down your loan faster and with less interest, but other strategies provide the same benefits.

For example, you can speed up your amortization by making an additional principal payment each month. Typically, these payments can be made by specifying “additional principal payment” and can be made online, by phone, or by noting it on your loan coupon. If you’re enrolled in auto pay, you can set up regular additional principal payments through your account online or by contacting your bank or lender. Depending on the extra payment’s size, it could reduce your principal and build equity more quickly than biweekly payments.

The main advantage to making an extra principal payment each month is that you can scale back if needed. So if you run into a financial emergency, you can stop making the additional payments until the matter is resolved.

Choosing biweekly payments or making extra principal payments can help you pay off your loan faster and save on interest. This table shows how much time and money you could save on a $350,000 mortgage at 5.89% interest compared with traditional monthly payments:

By making biweekly mortgage payments, you can save more than $86,000 in interest payments and pay off the debt six years sooner. Adding $200 of extra principal to a standard monthly payment shortens the loan by the same amount of time, but provides nearly $6,000 more in interest savings.

Choose a shorter-term mortgage. Another strategy to consider is a 15- or 20-year mortgage. Your mortgage payments will be higher, but you’ll pay off your house faster, and shorter-term mortgages often feature lower interest rates, saving you even more money.

The main drawback to a shorter loan is that you’re locked into a bigger mortgage payment. If something unexpected happens—maybe you lose your job or have an emergency medical expense—you still have to make that big payment. Unless you have an emergency fund to fall back on, you may find yourself scrambling to make ends meet.

Another way to accomplish the same goal is to get a 30-year mortgage but make payments as though it’s a 15-year loan. You’ll need to calculate how much additional principal to add to your monthly payment to meet your desired payoff date. Making additional principal payments can help you pay off your house faster while still maintaining the flexibility to stop making the extra payments if needed.

Refinance to a shorter term. Just because you signed on to a 30-year mortgage doesn’t mean you need to stick with it. If you’re only a few years in, refinancing your mortgage to a shorter term could still save you thousands—especially if rates are lower than when you got your loan. Keep in mind that refinancing typically involves hefty closing costs, so run the numbers first to determine whether taking out a new loan makes sense.

Make principal payments with windfalls. Most mortgage loans allow you to make additional principal payments at any time. If you can’t commit to regular extra payments, consider earmarking any windfalls—such as bonuses or tax refunds—for principal payments whenever they occur.

This method won’t pay down your debt as quickly, and you won’t have an easily predicted end date for your mortgage, but you can still save money on interest and shave some time off the life of the loan.

Your mortgage will likely cost you a lot of money over time, but you can reduce how much you pay overall. Biweekly mortgage payments are an easy way to expedite loan repayment and pay less interest with little or no effect on your budget. And you may be able to switch to biweekly payments with your current 30-year mortgage—just watch out for fees.

Bimonthly payments are similar to biweekly payments, but differ in the number of payments and how often they are applied. They can save you a bit in interest, but the term of the loan remains the same. The benefit mainly lies in making two smaller payments rather than one big one each month, which can help with budgeting.

An alternative is to make additional principal payments, whether monthly, quarterly, or once a year. The key is to be consistent. Steady additional payments could lop years off your mortgage and save you thousands of hard-earned dollars, making home sweet home that much sweeter.
