Student Loan Payoff Date Calculator
This calculator returns the date you will make your final student loan payment. Enter your balance, rate, and monthly payment to see your debt-free date and total interest paid. On a $28,000 balance at 5.5% with $310 per month, payoff falls roughly nine years out with over $5,000 in interest. Even a small payment increase pulls that date closer.

This payment is below the of interest the balance accrues each month, so the debt grows instead of shrinking.
Of this month's payment, comes off the principal and covers interest.
Interest accrues daily, so the number on a payoff quote is only good for the day it was issued — ask your servicer for a dated 10-day payoff quote before you send a final payment.
Why Your Payoff Balance Differs from Your Statement Balance
Interest on student loans accrues daily using the formula: principal multiplied by annual rate divided by 365.25. On a $28,000 balance at 5.5%, that is approximately $4.21 per day. Between the date your servicer generates a statement and the date your payoff check clears, additional interest accumulates. This is why a payoff quote—a servicer-provided figure that includes interest through a specific future date—is always higher than the balance shown on your last statement.
Borrowers on student-loan forums report frustration when they send what they believe is a final payment only to receive a bill for a few dollars of residual interest. The standard advice is to request a payoff quote from your servicer dated a few days past your expected payment arrival. This calculator models daily accrual so you can anticipate the difference, but the payoff quote remains the binding number. If you are within two months of paying off, request that quote before sending a lump sum.
Daily Interest and the Payoff Timeline
Early in your repayment, most of each monthly payment goes to interest. On a $28,000 loan at 5.5%, month-one interest is roughly $128 (illustrative), meaning only $182 of a $310 payment reduces principal. By the final year, nearly the entire payment goes to principal because the balance—and therefore daily interest—has shrunk. This front-loading of interest is standard amortization, and it explains why extra payments early in the loan save more than extra payments late.
The calculator displays a month-by-month breakdown showing the interest-to-principal split. Use it to identify the period where accelerating payments delivers the greatest return. Even rounding up your payment—$310 to $350, for instance—shifts the payoff date forward and reduces total interest. For a structured extra-payment plan, see the extra-payment calculator. To compare multi-loan payoff strategies, try the avalanche-vs-snowball tool. The total-cost calculator shows the lifetime price tag in full.
This calculator uses standard amortization. Your actual payoff amount may differ due to accrued interest, fees, or servicer processing time. Always request a payoff quote.
