How this calculator works
There are 26 two-week periods in a year, so paying half your bill every two weeks adds up to 13 full payments instead of 12. The calculator models that as one-twelfth extra each month and compares payoff time and interest with the regular schedule.
Worked example
With the example values below: Paid off, 1 yr sooner (paying $170.32 every two weeks). Change any number above to run your own.

Why biweekly payments help
There are 52 weeks in a year, so paying half your monthly bill every two weeks means 26 half-payments, the same as 13 full monthly payments instead of 12. That one extra payment a year goes to principal and shortens the loan.
On $30,000 at 6.5% over 10 years, the regular payment is about $341. Paying half of that every two weeks pays the loan off roughly a year and a few months early and saves about $1,200 in interest.
How to set it up
Federal servicers bill monthly, and a payment that arrives early is often applied to the next due date rather than reducing principal. The simplest way to get the benefit is to pay your normal monthly amount plus one-twelfth extra each month, which is exactly what this calculator models.
If you do pay every two weeks, ask your servicer to apply any amount above the monthly bill to principal, and check that it isn't held until the due date.
Who benefits most
It won't help if you're on track for Public Service Loan Forgiveness, since the balance would be forgiven anyway.
- People paid every two weeks, who can match payments to paydays.
- Borrowers with higher-rate loans, where each extra dollar saves more.
- Anyone who wants to pay a bit extra without noticing it in their budget.
Avoid paid biweekly programs
Some companies charge enrollment or monthly fees to set up biweekly payments for you. You can get the same effect for free by adding one-twelfth to each monthly payment. For a bigger effect, combine it with extra principal; see the student loan payoff calculator.
Frequently asked questions
Do biweekly student loan payments save money?
Yes. Paying half your bill every two weeks adds one full payment a year, which goes to principal. On $30,000 at 6.5% over 10 years, that saves about $1,200 and finishes over a year early.
Can I make biweekly payments on federal student loans?
You can make payments whenever you like, but servicers bill monthly and may hold early payments until the due date. Adding one-twelfth extra to each monthly payment gets the same result more reliably.
How much sooner will I pay off my loan with biweekly payments?
Typically about a year sooner on a 10-year loan, and more on longer terms or higher rates.
Is biweekly the same as paying one extra payment a year?
Almost exactly. Twenty-six half-payments equal 13 full payments. Spreading the extra across the year saves slightly more interest than one lump sum at year-end.
Does paying biweekly affect my credit?
Not directly. What matters for credit is paying at least the full monthly amount by the due date every month.
