| Scenario | Loan Amount | Rate | Fee | Term | Months Before Repayment | Extra Payment |
|---|---|---|---|---|---|---|
| Undergraduate first year | $5,500.00 | 6.390% | 1.057% | 10 years | 54 | $0.00 |
| Graduate annual loan | $20,500.00 | 7.940% | 1.057% | 10 years | 30 | $25.00 |

Formula Used
Loan fee: Fee = Gross loan × Fee rate
Net amount received: Net = Gross loan − Fee
Daily interest: Daily interest = Principal × Annual rate ÷ 365.25
Interest before repayment: Pre-repayment interest = Daily interest × Waiting days
Standard monthly payment: M = P × r ÷ (1 − (1 + r)^−n)
Payment order: payment is applied to unpaid interest, current interest, and then principal.
Here, P is the repayment balance, r is the monthly interest rate,
and n is the number of monthly payments.

Federal Direct Unsubsidized Loan Planning Guide
Why This Loan Needs Careful Planning
A Federal Direct Unsubsidized Loan can help students cover education costs. It is different from a subsidized loan. Interest starts on the day funds are disbursed. The borrower is responsible for every dollar of that interest.
What the Calculator Measures
This calculator focuses on three cost layers. First, it estimates the origination fee. That fee reduces the cash sent to the school. Second, it estimates interest during school, grace, deferment, or waiting periods. Third, it builds a repayment schedule with monthly interest, principal reduction, and payoff time.
How Interest Changes the Balance
Unsubsidized loans are simple interest loans. That means interest is based on the current principal balance. It does not usually compound each day. However, unpaid interest can be capitalized at important points. Capitalization adds unpaid interest to principal. Future interest then uses the larger balance.
Testing Repayment Choices
The tool lets you test that risk. Enter months before repayment. Add any monthly interest payment you plan to make while enrolled. Then choose whether unpaid interest should capitalize. The results show starting repayment balance, total interest, total paid, and cost above the amount received.
Extra payments can change the story. Even a small extra amount may reduce payoff time. It may also lower total interest. This calculator compares the active plan with a no-extra baseline. That makes the saving easier to see.
Borrowing Less Can Help
Use the annual limit and aid gap fields for planning. They help compare the requested loan against expected school costs. They do not replace official award letters. They simply give a useful planning view.
Review several scenarios before borrowing. Try the full award amount first. Then test a smaller loan. Add expected part-time earnings or scholarships. A lower borrowed amount can reduce fees, interest, and future pressure after graduation each month later on.
Using the Output
The amortization table shows the monthly path. Early payments usually contain more interest. Later payments usually contain more principal. The chart makes that pattern clearer. Export the table to CSV for spreadsheets. Export the summary to PDF for records.
Important Reminder
This calculator is best for estimates. Real billing can change because of disbursement dates, repayment plan choices, servicing rules, and borrower actions. Always confirm exact terms with your loan servicer or official aid portal before making decisions.
Frequently Asked Questions
What is a Federal Direct Unsubsidized Loan?
It is a federal student loan where the borrower pays all interest. Interest starts when the loan is disbursed, even if payments are not due yet.
Does this calculator use fixed rates?
Yes. It treats the entered rate as fixed for the estimate. You can edit the rate to match the loan year shown in your official aid documents.
Why is the amount received lower than the loan?
The origination fee is deducted before funds are disbursed. You still repay the full borrowed amount, not only the cash received by the school.
What does capitalization mean?
Capitalization adds unpaid interest to the principal balance. After that, new interest is calculated on a larger amount, which can increase total cost.
Can I pay interest while in school?
Yes. Enter a monthly interest payment before repayment. The calculator reduces unpaid interest and may lower the amount capitalized later.
How do extra payments help?
Extra payments reduce principal faster after interest is covered. That can shorten the payoff timeline and reduce total interest paid.
Is this an official repayment quote?
No. It is an educational estimate. Your servicer or official student aid portal should be used for exact balances, billing rules, and payoff quotes.
Why include cost of attendance and other aid?
Those fields help compare requested borrowing with your remaining school cost. This supports better planning before accepting a loan amount.
