Required monthly payment
$2,279.65
On a $320,000 loan at 7.24% with 312 months left, a biweekly schedule saves $87,309 of interest — but paying the same 13 payments a year yourself saves $86,298, so the schedule is worth $1,011 and the service charges $1,415.
Assumptions this tool makes. The biweekly schedule pays half the monthly payment every two weeks and accrues interest every two weeks at one twenty-sixth of the annual rate, which is how the schedule is usually administered. The do-it-yourself comparison adds one twelfth of the payment to each monthly payment and accrues interest monthly. The loan is fixed-rate; the payment is principal and interest only. Fees are taken as paid in cash at the start and at the beginning of each year of the window. The interest figures run to payoff, so they describe a loan held to the end; the balance figure describes a loan still outstanding at the end of the window.
A biweekly schedule does not save interest because it pays every two weeks. It saves interest because it pays thirteen monthly payments a year instead of twelve. Half a payment every two weeks is 26 halves, and 26 halves is 13 payments, so the extra payment arrives without the owner ever deciding to make one.
On the default figures the monthly payment is $2,279.65, so the biweekly payment is $1,139.83 and the year totals $29,635 against $27,356 on the monthly schedule. That $2,280 of extra principal every year compounds: the loan pays off in 21.1 years instead of 26, and the interest bill falls from $391,252 to $303,943. None of those numbers is in dispute, and the companies selling the service quote them accurately.
The same thirteen payments can be made on a monthly schedule, at no cost, by adding one twelfth of the payment to every payment. That produces the same extra principal in the same year, and the interest saved is $86,298 against the biweekly schedule's $87,309. The difference is $1,011 over 26 years, and it exists only because the biweekly schedule applies the extra money a couple of weeks earlier inside each month.
One thousand and eleven dollars is the entire value of the mechanism. A setup fee of $995 plus an annual fee consumes that value before the first year is out. Inside a five-year window the service is worth $75 of extra principal against $1,415 charged — a loss of $1,340, which is the number at the top of this page.
The one thing the fee genuinely buys is that the extra payment happens without the owner remembering it. That is a real service, and it is worth something to someone whose alternative is missing the extra payment every year. It is not worth anything to someone who can set a standing instruction at their own bank, which is the same automation with no fee and no third party holding the payment.
The Consumer Financial Protection Bureau's action against Nationwide Biweekly Administration did not turn on the size of the fee. It turned on what borrowers were told about it: that the advertised savings were not achievable on the schedule sold, and that the setup and annual charges were not disclosed the way the marketing presented them. The settlement came to $7,930,000.
That distinction matters when reading any page on this subject, including sales material. A claim that a biweekly schedule saves interest is arithmetically true and legally unremarkable. A claim that the service saves that interest is a different claim, and it is the one that has to be measured against the free substitute.
The fee structure in the case is the reason the inputs on this page default where they do: a setup fee of $995 and an annual fee between $84 and $101. A service priced differently moves the answer, which is why both fields are inputs rather than constants.
Three steps, none of which needs a third party. Divide the monthly payment by twelve and add that amount to the payment, either as a higher monthly payment or as a separate principal-only payment. Mark the extra as principal so the servicer does not apply it to the next instalment. Check once a year that the balance is falling faster than the original schedule said it would.
A borrower who cannot trust themselves to make the extra payment every year is in a different position, and the calculator is honest about that: it values the automation at zero because automation is not what it measures. What it measures is the arithmetic, and the arithmetic says the schedule is worth $1,011 while the service charges $1,415.
Yes, and the amount is large: $87,309 on the default loan, which pays off in 21.1 years instead of 26. The saving does not come from the two-week frequency, though. It comes from making 26 half-payments, which is 13 full payments a year instead of 12. Any method that produces 13 payments a year produces almost all of the saving.
Yes. Divide your monthly payment by twelve and add that amount to each payment, labelled as principal. That is the same 13 payments a year, and on the default figures it saves $86,298 against the biweekly schedule's $87,309. The $1,011 difference is the only thing the schedule adds, and the service charges more than that.
It does not change the arithmetic; it explains why the arithmetic is worth doing. The regulator's case against Nationwide Biweekly Administration concerned what borrowers were told about the savings and the fees, not the size of the fee itself, and it settled for $7,930,000. The page separates the two questions on purpose: what the schedule is worth, and what the service charges for it.
Most fixed-rate mortgages allow it without penalty, but the mechanics differ. Some servicers apply an unlabelled payment to the next instalment instead of to principal, which delays the benefit; a few require the extra amount to be sent separately with instructions. The annual statement is the check: if the balance is not falling faster than the original schedule, the extra money is not reaching principal.
In the arrangements the regulator examined, yes — the setup fee and the annual fee were taken from the borrower's account, which is part of why the case was brought. On this page both are inputs, so a service quoting a different structure can be tested. A setup fee alone with no annual charge changes the answer substantially, and so does an annual fee charged for 21 years instead of five.

Cluster us/mortgage · Unit us-mortgage-biweekly-payment-service-fee · Engine amortizing-loan / biweekly-fee · Method: The biweekly path pays half the monthly payment every two weeks, 26 times a year, and accrues interest at one twenty-sixth of the annual rate per period, so it makes 13 monthly payments a year instead of 12. The do-it-yourself path pays one twelfth of the monthly payment on top of every monthly payment under normal monthly accrual, which produces the same 13 payments a year. Both are run to payoff for the lifetime interest comparison, and to the end of the chosen window for the balance comparison. The service fee is the setup fee plus the annual fee multiplied by the number of years in the window. Principal repaid ahead of the monthly path is the difference between the remaining balances at the end of the window.
