Loan Summary
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)
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
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)
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:
Plan | Term | Monthly Payment | Eligibility | Forgiveness |
---|---|---|---|---|
Standard | 10 years | Fixed payments | All borrowers | No |
Graduated | 10 years | Starts low, increases every 2 years | All borrowers | No |
Extended | Up to 25 years | Lower payments | Federal loan balance of $30,000+ | No |
Income-Based Repayment (IBR) | 20–25 years | 10–15% of discretionary income | Must demonstrate financial need | Yes |
Pay As You Earn (PAYE) | 20 years | 10% of discretionary income | First loan after Oct. 2007 | Yes |
Revised PAYE (REPAYE) | 20–25 years | 10% of discretionary income | All Direct Loan borrowers | Yes |
Income-Contingent Repayment (ICR) | 25 years | Lesser of 20% of income or fixed plan | All Direct Loan borrowers | Yes |
Income-Sensitive Repayment | 10 years | Based on income | FFEL borrowers | No |
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.
