Is a biweekly payment plan always better than monthly payments?

A true biweekly plan usually leads to faster payoff and lower total interest because you effectively make one extra payment per year. However, whether a paid service is worth it depends on the fees. If you can achieve the same effect on your own without paying fees, you may prefer a DIY approach.

Can I set up biweekly payments directly with my lender?

Many lenders will let you split your payment into biweekly drafts or make extra principal payments without a third-party service. Check with your lender first—if they support it for free or a modest fee, you may not need a separate biweekly company.

Does this calculator handle partial years or early payoff due to sale/refi?

It assumes you carry the loan for the full term under each payment plan. If you expect to move or refinance sooner, your actual savings will be smaller. You can still use the results as a rough upper bound on potential savings.

What if the biweekly service only drafts biweekly but pays the lender monthly?

If the service simply holds your payments and remits a single monthly payment, you may not get the full benefit of a true biweekly schedule. Ask the provider exactly how and when they forward payments to your lender and consider a DIY extra-payment strategy instead.

Should I prioritize a biweekly plan over paying down higher-interest debt?

Not usually. If you have higher-interest debt (such as credit cards or personal loans), it often makes more sense to pay that down first. Use a biweekly or extra-payment strategy where it fits within a broader debt- and savings plan.

Biweekly Mortgage Service vs DIY

Compare biweekly payment interest savings to the fees charged by a biweekly payment service to see if it’s worth paying for.

Results

Monthly payment (P&I): $1,896
Biweekly payment (P&I): $875
Total interest (monthly plan): $382,633
Total interest (biweekly plan): $382,312
Interest saved with biweekly: $322
Biweekly service fees: $100
Net savings after fees: $222

How to use this calculator

Enter your mortgage loan amount, annual interest rate (APR), and term in years to establish the baseline monthly payment and interest.
Enter the biweekly payment service setup fee (a one-time charge) and any monthly service fee the company plans to charge.
The calculator computes the standard monthly payment, biweekly payment amount, total interest under both plans, and the raw interest saved by switching to biweekly.
It then calculates the total fees you would pay to the biweekly service over the period modeled and subtracts those fees from the interest savings.
Review the net savings after fees to decide whether paying a biweekly service is worthwhile or whether you’d rather replicate the effect for free by managing extra payments yourself.

Inputs explained

Loan amount: The mortgage principal you owe or plan to borrow. This is the balance on which we calculate your standard payment and simulate monthly vs biweekly schedules.
Annual interest rate (APR %): The fixed annual percentage rate on your mortgage. We convert this to a monthly rate and a biweekly equivalent to simulate both payment schedules consistently.
Term (years): The length of the mortgage in years (commonly 15, 20, or 30). This determines how many monthly or biweekly payments are modeled in the baseline schedule.
Service setup fee: A one-time fee charged by the biweekly payment service to enroll or set up your plan. Some companies charge a significant upfront amount; others may charge none.
Service monthly fee: The recurring fee charged every month by the biweekly service to process your payments. This may be a small flat fee or a percentage; enter the flat monthly amount you will pay.

How it works

We start by computing the standard monthly principal-and-interest payment for your loan amount, APR, and term in years using the fixed-rate amortization formula.

We then simulate a conventional monthly payment plan across the entire term, tracking total interest paid over the life of the loan when you make one payment per month.

Next, we model a biweekly payment plan that makes 26 half-payments per year (roughly every two weeks). Because there are 26 half-payments instead of 24, this schedule effectively makes one extra full payment per year, which reduces the loan balance faster and cuts interest.

From the biweekly simulation, we calculate the total interest paid under the biweekly plan and compare it to the total interest under the standard monthly plan to find your interest savings before fees.

We add up the biweekly service’s setup fee and any ongoing monthly fees over the life of the plan, then subtract these fees from your interest savings to compute net savings. A positive net savings means the service still saves you money after fees; a negative value means the fees outweigh the interest benefit and you’d be better off self-managing a similar strategy.

Formula

Monthly plan:\nMonthly rate r = APR ÷ 12\nNumber of payments N = Term years × 12\nMonthly payment = L × [r(1 + r)^N] ÷ [(1 + r)^N − 1]\nSimulate amortization month by month to find total interest.\n\nBiweekly plan (conceptual):\nBiweekly rate ≈ APR ÷ 26\nBiweekly payment ≈ Monthly payment ÷ 2\n26 biweekly payments per year → roughly one extra full payment annually.\nSimulate biweekly amortization to find total interest and payoff timing.\n\nInterest saved = Total interest (monthly) − Total interest (biweekly)\nTotal fees = Setup fee + (Monthly service fee × number of months modeled)\nNet savings = Interest saved − Total fees

When to use it

Evaluating marketing claims from biweekly mortgage companies that promise big savings by automatically splitting your payment into half-payments every two weeks.
Deciding whether to sign up for a paid biweekly program or simply make one extra principal payment per year yourself or set up your own biweekly schedule via your bank.
Comparing different fee structures by adjusting setup and monthly fees to see at what point the biweekly service’s cost wipes out its interest savings.
Helping borrowers understand that the main benefit of biweekly payments comes from effectively making one extra payment per year—not from any special magic offered by third-party companies.
Using net savings estimates as part of a broader conversation about debt payoff strategies and whether to prioritize prepayments, refinancing, or investing extra cash.

Tips & cautions

In many cases you can replicate the benefits of a biweekly plan by making one extra full payment per year or by adding a fixed extra amount to each monthly payment—without paying service fees.
Some lenders allow you to set up a true biweekly payment schedule directly with them at little or no charge. Check with your lender before paying a third party.
Watch out for services that merely hold your payments and remit them monthly while still charging you biweekly—this may not generate the same interest savings as a true biweekly application of funds.
If you plan to refinance or sell the home well before the end of the term, your actual savings from biweekly payments will differ; consider how long you realistically expect to keep the mortgage.
Ensure that any extra or more frequent payments are applied to principal, not just held in a suspense account, so you actually reduce the balance and interest charges.
Assumes a fixed-rate mortgage and a full-term comparison. Adjustable-rate mortgages or loans paid off early due to refinance or sale will have different real-world savings.
Models a standard biweekly pattern with 26 half-payments per year; variations in exact timing, partial months, or lender-specific posting rules may slightly alter actual interest results.
Does not include taxes, insurance, or PMI; it focuses solely on principal and interest when calculating payment and interest savings.
Treats service fees as simple upfront and monthly charges; it does not model complex fee schedules or percentage-based fees tied to payment amounts.
Uses a simplified amortization model for comparability; lender calculations may differ slightly due to rounding, day-count conventions, and exact posting dates.

Worked examples

Example 1: Moderate loan with small service fees

Loan amount = $300,000; APR = 6.5%; term = 30 years.
Biweekly service setup fee = $100; service monthly fee = $3.
The biweekly schedule may save several thousand dollars in interest over the life of the loan compared to monthly payments.
Subtract total service fees over the term from the interest savings to see whether the biweekly program still yields a meaningful net benefit.

Example 2: High fees erasing biweekly benefit

Increase service fees—e.g., setup fee = $395 and monthly fee = $10.
Re-run the calculator and observe that total fees now approach or exceed the gross interest savings from the biweekly schedule.
Interpretation: in this scenario, paying for the service could yield little or no net savings compared to staying monthly or self-managing extra payments.

Example 3: DIY alternative

Use this calculator’s interest-savings estimate without fees as a benchmark.
Consider setting up your own extra-payment plan that mimics biweekly payments (for example, adding 1/12 of a monthly payment as extra each month).
Compare this DIY approach—with zero service fees—to the paid biweekly service’s net savings to decide which makes more sense.
