Three Biweekly Payment Strategies

1. True Biweekly Payment (26 Payments Per Year)

With this strategy, you make a payment every two weeks instead of once a month. Since there are 52 weeks in a year, you'll make 26 half-payments, which equals 13 full monthly payments annually instead of 12. This extra payment goes directly toward your principal balance.

How it works: Your monthly payment is divided by 2, and you pay that amount every 14 days. Over the course of a year, you naturally make one extra full payment.

Best for: Borrowers who get paid biweekly and want to align their loan payments with their paycheck schedule.

2. Half-Year Extra Payment (Semi-Annual)

This method involves making your regular monthly payments plus an additional half payment every six months (typically in June and December). You make 12 regular monthly payments plus 2 half-payments per year, totaling 13 full payments annually.

How it works: Continue your normal monthly payment schedule, but twice a year, add an extra payment equal to half your regular monthly amount.

Best for: Borrowers who receive bonuses, tax refunds, or have seasonal income fluctuations and prefer scheduled extra payments.

3. Annual Extra Payment

With this approach, you make 12 regular monthly payments plus one additional full payment once per year. This results in 13 full payments annually, identical in total to the other methods but concentrated in a single extra payment.

How it works: Make your regular monthly payment throughout the year, then make one additional full payment at a predetermined time (often when you receive a year-end bonus or tax refund).

Best for: Borrowers who receive annual bonuses or prefer to make one larger extra payment rather than multiple smaller ones.

Important Note: All three strategies result in making 13 full payments per year instead of 12, but they differ in timing and payment frequency. The true biweekly method typically saves slightly more interest because payments are applied to the principal more frequently throughout the year.

FAQ

Q: Why Doesn't "Payoff In" + "Time Saved" Add up Exactly to My Original Loan Term?

A: The week values shown are rounded down to the nearest whole week. For example, if the remaining days come out to 9 days, that displays as 1 week — the extra 2 days are still counted in the total days figure but aren't reflected in the week count. Add up the total days from both fields and you'll find they match your original loan term precisely.

Q: What's the Difference Between the Three Biweekly Options?

A: True Biweekly means you actually make a payment every 14 days — that's 26 payments per year instead of 24, which is where the savings come from. Half-Year Extra keeps your normal monthly payments but adds an extra half-payment every 6 months. Annual Extra does the same but adds one full extra payment once a year. All three reduce your total interest, just through different mechanisms.

Q: Why Does True Biweekly Save More Than the Other Two Options?

A: With True Biweekly, each payment reduces your principal balance every 14 days, so interest accrues on a lower balance more frequently throughout the year. The other two options make the same extra contribution annually but in larger, less frequent chunks — so interest has more time to accumulate between payments.

Q: How Is the Biweekly Interest Rate Calculated?

A: The annual rate is divided by 26 (not 24) to get the per-period rate. This reflects that there are 26 biweekly periods in a year, which is what makes True Biweekly genuinely different from just splitting your monthly payment in half.

Q: Why Does the Amortization Table Show $0.00 in Some Rows?

A: Once a loan is paid off under the biweekly plan, the remaining rows in the comparison table show $0.00 to indicate no further payments are needed — while the original schedule may still have months remaining. This makes the time savings easy to see at a glance.
