Loan Summary

Monthly Payment: $345.12
Total Interest: $11,414.40
Total Cost: $41,414.40
Payoff Date: MM/YYYY
Loan Payment Formula:
PMT = P × (r(1+r)^n) / ((1+r)^n - 1)
Where:
PMT = Monthly payment amount
P = Principal loan amount ($30,000 in example)
r = Monthly interest rate (annual rate ÷ 12 → 6.8% ÷ 12 = 0.5667%)
n = Total number of payments (loan term × 12 → 10 × 12 = 120)
Example Calculation:
For a $30,000 loan at 6.8% over 10 years:
Monthly rate (r) = 6.8% ÷ 12 = 0.005667
PMT = 30,000 × (0.005667 × (1+0.005667)^120) / ((1+0.005667)^120 - 1)
PMT = 30,000 × (0.005667 × 1.967) / (1.967 - 1) = $345.12

Student Loan Projection Calculator

Estimate your loan balance and repayment obligation after graduation.

Do you pay interest during school years?

Loan Projection

Total Loan at Graduation: $43,456.20
Monthly Payment: $500.23
Total Interest: $16,571.60
Total Cost: $60,027.80
Payoff Date: MM/YYYY
Projection Calculation Method:
The projection calculator estimates your total loan balance at graduation by:
1. Adding annual loan amounts to your current balance
2. Accruing interest during school years (unless you pay interest)
3. Accruing interest during grace period (unless you pay interest)
4. Calculating standard repayment based on final balance

Same monthly payment formula used for repayment period:
PMT = P × (r(1+r)^n) / ((1+r)^n - 1)
Example Scenario:
Current balance: $20,000
Annual borrowing: $10,000 for 2 years
Interest rate: 6.8% (not paid during school)
Grace period: 6 months
Repayment term: 10 years
Total at graduation: $43,456.20
Monthly payment: $500.23

Overview of Student Loans in the U.S.

In the United States, student loans are primarily offered by either government programs or private lenders. Most student loan debt comes from federal and state-backed programs, which often include benefits like subsidized interest and flexible repayment terms. Subsidized loans allow students to defer interest payments while in school, making them more affordable than private options. Additionally, federal loans usually have lower interest rates and don’t require a cosigner—just proof of enrollment. Because of these advantages, over 90% of all student debt in the U.S. comes from federal loans.

Before You Borrow – Consider Other Financial Aid

Before turning to student loans, students should explore alternative funding options:

  • Grants and Scholarships: These do not need to be repaid and can cover partial or full education costs.

  • Work-Study Programs: Offer part-time jobs for students with financial need.

  • Personal Savings or Income: Using available funds early can reduce the amount needed in loans.

Loans should be a last resort after maximizing all other available aid sources.

Types of Student Loans

Federal Student Loans

The U.S. Department of Education provides several loan programs with favorable terms:

Direct Subsidized & Unsubsidized Loans (Stafford Loans)

  • Subsidized: Based on financial need (EFC), interest is covered while in school and during a 6-month grace period after graduation.

  • Unsubsidized: Not need-based. Interest begins accruing immediately upon loan disbursement.

Direct PLUS Loans

Available to graduate students or parents of dependent undergrads. Requires a credit check and can fund the gap between the cost of attendance and other financial aid. These loans have higher interest rates and a 4% origination fee.

Direct Consolidation Loans

Combine multiple federal student loans into one. Benefits include:

  • A single monthly payment

  • Extended repayment terms

  • Access to income-driven plans
    However, consolidation can result in paying more interest over time and may eliminate certain borrower benefits.

State-Based Student Loans

Each state runs its own student loan programs through agencies or nonprofit partners. These vary widely and may include:

  • Special forgiveness programs (e.g., for teachers or nurses)

  • Requirements to remain in-state after graduation

  • Earlier deadlines than federal aid
    Students should check with their state’s higher education office to learn about available aid.

Private Student Loans

Private loans come from banks, credit unions, or lending institutions. Key features include:

  • Credit-based approval (often needing a cosigner)

  • No subsidy—interest accrues from day one

  • Typically higher, sometimes variable, interest rates
    Private loans are often used to cover costs not met by federal aid. Some institutions offer school-sponsored loans with slightly better terms. These loans are not eligible for federal forgiveness programs but can offer:

  • Fast approval and funding

  • Tax-deductible interest in some cases

  • Flexible usage requirements

Student Loan Repayment Plans

Paying back student loans can be difficult, especially for recent grads. Federal loans offer multiple repayment options designed to ease the burden:

 

PlanTermMonthly PaymentEligibilityForgiveness
Standard10 yearsFixed paymentsAll borrowersNo
Graduated10 yearsStarts low, increases every 2 yearsAll borrowersNo
ExtendedUp to 25 yearsLower paymentsFederal loan balance of $30,000+No
Income-Based Repayment (IBR)20–25 years10–15% of discretionary incomeMust demonstrate financial needYes
Pay As You Earn (PAYE)20 years10% of discretionary incomeFirst loan after Oct. 2007Yes
Revised PAYE (REPAYE)20–25 years10% of discretionary incomeAll Direct Loan borrowersYes
Income-Contingent Repayment (ICR)25 yearsLesser of 20% of income or fixed planAll Direct Loan borrowersYes
Income-Sensitive Repayment10 yearsBased on incomeFFEL borrowersNo

Note: Public service employees may qualify for loan forgiveness after 10 years of eligible payments under certain plans. Forgiveness may not be tax-exempt unless specified.

Most borrowers are placed on the Standard Repayment Plan by default. Regardless of the plan, federal and private student loans allow penalty-free early repayment, enabling borrowers to reduce interest costs over time.
