How Biweekly Payments Work
Making biweekly payments means you pay half your monthly payment every 2 weeks, resulting in 26 payments per year (52 weeks ÷ 2). This equals 13 full payments per year, helping you pay off your loan faster and save on interest.
Paying off a mortgage is one of the most significant financial journeys for any homeowner. With traditional monthly payments, you’re often paying tens or even hundreds of thousands in interest over the life of your loan. But what if a simple adjustment to your payment schedule could shave years off your loan term and save you thousands in interest? That’s exactly what our Biweekly Mortgage Payment Calculator is designed to help you uncover.
Whether you’re a first-time homebuyer or refinancing your current mortgage, this tool offers a smart way to visualize the real benefits of switching to a biweekly payment schedule — without doing any complicated math yourself.
How to Use the Biweekly Mortgage Calculator
Our intuitive calculator guides you through just four simple steps. Here’s how you can use it:
Step 1: Enter the Loan Amount
Input the original loan amount you borrowed or plan to borrow. For example, if your mortgage is $300,000, type in 300000.
Step 2: Add the Interest Rate
Enter the annual interest rate (APR) of your mortgage. This value is usually provided by your lender and looks like 5.5, 6.75, etc.
Step 3: Input the Loan Term in Years
This is the duration of your loan. Common options are 15, 20, or 30 years.
Step 4: Select the Loan Start Date
Pick the date when your loan officially begins or began. The calculator will use this to estimate your payoff date under a biweekly payment plan.
Step 5: Click “Calculate”
Once you’ve entered all fields, hit the Calculate button. The progress bar will animate, and in a few seconds, you’ll see your full results.
Step 6 (Optional): Reset, Copy or Share
You can reset the form, copy results to clipboard, or share the outcome with others via the provided buttons.
