How Making Two Extra Mortgage Payments a Year Cuts Your Loan Short
What happens when you pay an extra mortgage payment twice a year
When you make two extra payments toward your mortgage principal each year, you shorten the life of your loan and reduce the total interest you pay. Most people do this by splitting one regular monthly payment in half and sending it twice a month, or by sending one full extra payment every six months. The money goes directly to principal—the amount you actually borrowed—not to interest or escrow.
The math is straightforward: if your regular payment is $1,200 and you send an extra $1,200 twice a year, you've paid $2,400 more toward principal than your loan agreement requires. Over 30 years, this compounds. You'll pay off the loan years earlier and save tens of thousands in interest, depending on your loan amount and rate.
The catch is that this only works if your lender actually applies the extra payment to principal. Some lenders hold extra payments in escrow or apply them to next month's regular payment instead. Before you start, contact your mortgage servicer and ask exactly how they handle extra principal payments—get the answer in writing.
Key Takeaways
- Two extra mortgage payments per year go directly to principal, not interest, which shortens your loan term by several years.
- Your lender must agree to apply extra payments to principal; some servicers hold them or apply them to your next regular payment instead.
- The total interest you save depends on your loan balance, interest rate, and how early you pay it off—typically $30,000 to $100,000+ over the life of a 30-year loan.
- You can send extra payments as two lump sums per year, or split your regular payment in half and send it twice monthly.
- Extra payments are voluntary and optional; you cannot be forced to make them, and missing them does not affect your credit or loan status.
How to set up extra payments with your servicer
Call your mortgage servicer—the company that collects your monthly payment, not necessarily the bank that originated the loan—and ask for their procedure for extra principal payments. Some servicers have an online portal where you can schedule them yourself. Others require a written request or a phone call each time.
When you contact them, ask three specific things: (1) Can you send extra payments online, by mail, or by phone? (2) Do they charge a fee for extra payments? (3) Will they confirm in writing that the extra payment goes to principal, not to your next month's regular payment? Write down the name and date of the person you spoke with, and keep any written confirmation they send.
Some servicers require you to send extra payments separately from your regular payment—using a different check, account, or payment method—so the system doesn't confuse it with your regular installment. Others let you combine them. Ask which method your servicer uses, because sending it the wrong way can cause delays or misapplication.
The real savings: how much interest you actually avoid
The amount you save depends on three factors: your loan balance, your interest rate, and how many years earlier you pay off the loan. On a $300,000 loan at 6% interest over 30 years, two extra payments per year can save you roughly $60,000 to $80,000 in interest and cut 5 to 7 years off your loan. On a $500,000 loan at the same rate, the savings climb to $100,000 or more.
The higher your interest rate, the more you save by paying early. A loan at 7% interest saves more per extra payment than a loan at 4% interest, because you're avoiding more interest expense. Conversely, if you have a very low rate—say 2.5%—the savings are smaller, though still real.
You can calculate your own savings using an online mortgage payoff calculator. Enter your current loan balance, interest rate, remaining term, and the amount of extra principal you plan to send. The calculator will show you the new payoff date and total interest paid. This gives you a concrete number to decide whether the extra payments fit your budget.
When extra payments make sense for your situation
Extra mortgage payments work best if you have stable income, an emergency fund already in place, and no high-interest debt like credit cards. If you're living paycheck to paycheck or carrying credit card balances above 5%, paying down the credit card first usually makes more financial sense—credit card interest is almost always higher than mortgage interest.
Extra payments also make sense if you plan to stay in the home long enough to benefit from the early payoff. If you might sell or refinance within five years, the savings shrink because you won't hold the loan long enough to recoup the benefit. On the other hand, if you're in your home for the long term and want to own it free and clear before retirement, extra payments can be a reliable way to reach that goal.
If you receive a bonus, tax refund, or inheritance, sending part of it as an extra mortgage payment is a low-risk way to use unexpected money. You're not locking it away—you can still access your home equity through a line of credit if you need it—but you're reducing the debt you carry and the interest you owe.
The difference between biweekly payments and two extra annual payments
Biweekly payment plans—where you send half your monthly payment every two weeks instead of one full payment monthly—are sometimes marketed as a way to make an extra payment per year. This is technically true: 26 biweekly payments equal 13 monthly payments, so you do send one extra payment's worth of money per year. However, biweekly plans often come with setup fees, and some lenders charge a fee every time you make a payment.
Sending two lump-sum extra payments per year is simpler and cheaper. You control the timing, you avoid recurring fees, and you can skip a payment if your budget tightens without penalty. The math is the same—you're still sending extra principal twice yearly—but you have more flexibility and lower costs.
If your lender offers a biweekly program with no fees, it can work fine. But read the terms carefully. Some biweekly servicers hold your payments in escrow for weeks before applying them, which delays the benefit. Others charge $300 to $500 to set up the plan. For most people, simply sending two extra payments on your own schedule is cheaper and faster.
What to watch out for: common mistakes and traps
The biggest mistake is assuming your extra payment goes to principal when it actually goes to your next month's regular payment or sits in escrow. This happens more often than it should. Always get written confirmation from your servicer before you send the first extra payment, and check your statement after each extra payment to verify it reduced your principal balance, not just your next payment due.
Another trap is making extra payments while carrying high-interest debt elsewhere. If you're paying 18% on a credit card and 5% on your mortgage, sending money to the mortgage first is mathematically backward. Pay down the credit card first, then move to extra mortgage payments.
Some servicers charge a fee for extra payments or for paying off your loan early—called a prepayment penalty. This is less common now, but it still exists on some loans. Check your mortgage note or call your servicer to ask whether a prepayment penalty applies to your loan. If it does, calculate whether the interest you save still exceeds the penalty before you commit to extra payments.
How extra payments affect your taxes and home equity
Paying down your mortgage faster reduces the mortgage interest you can deduct on your taxes. If you itemize deductions, this means a smaller deduction each year. However, for most homeowners, the standard deduction is larger than itemized deductions anyway, so this tax effect is small or zero. Talk to a tax professional if you itemize and want to understand the exact impact on your return.
Extra mortgage payments increase your home equity—the difference between what your home is worth and what you owe on it. This is good for your financial security, but it does not immediately affect your credit score or borrowing power. Lenders look at your loan-to-value ratio (how much you owe compared to the home's value), and paying down principal improves that ratio over time.
If you ever need to borrow against your home through a home equity line of credit or refinance, having paid down principal gives you more options and better rates. But this is a long-term benefit, not an immediate one.
Frequently Asked Questions
Can I make extra mortgage payments without my lender's permission?
Yes, you can send extra money to your mortgage servicer anytime. However, you must specify that it should go to principal, not to your next regular payment. Without that instruction, the servicer may apply it incorrectly. Always include a note with your payment or call ahead to confirm how the extra payment will be handled.
What if I can't afford two extra payments every year?
You don't have to make them every year or on a fixed schedule. Send extra payments only when you have the money—after a bonus, tax refund, or when your budget allows. Even one extra payment per year reduces your loan term and interest. Consistency matters less than actually sending the money when you can.
Will making extra payments hurt my credit score?
No. Paying down your loan faster does not hurt your credit. In fact, it can help slightly over time by improving your credit utilization ratio (the amount of available credit you're using). Your credit score is based on payment history, credit mix, and other factors—not on how fast you pay off a loan.
Can I get my extra payment back if I need the money?
Once you send an extra payment to principal, it reduces your loan balance permanently. You cannot withdraw it like money from a savings account. However, you can borrow against your home equity through a home equity line of credit or refinance if you need cash. This is why extra payments work best when you have an emergency fund separate from your home.
Does making extra payments affect my ability to refinance?
No. Refinancing is based on your current loan balance, interest rate, home value, and credit score—not on whether you've made extra payments. In fact, having paid down principal can help you refinance on better terms because you owe less and your loan-to-value ratio is lower.
