This calculator is perfect for quick calculations. Enter any three of the following values and the calculator will compute the fourth:
This calculator helps you understand the impact of extra payments:
Ideal for students still in school or planning to attend:
The principal is the original amount of money you borrowed. This is the base amount on which interest is calculated. For example, if you borrow $30,000 for college, your principal is $30,000.
The interest rate is the percentage charged on your outstanding loan balance. Student loan interest rates can be fixed (stay the same over the loan's life) or variable (change over time based on market conditions). Federal student loans typically have fixed rates, while some private loans may have variable rates.
The grace period is a set amount of time after graduation (usually 6 months) before you must begin making payments on your student loans. For subsidized federal loans, interest doesn't accrue during this period. For unsubsidized loans, interest continues to accumulate.
Amortization is the process of gradually paying off a loan through regular payments. Each payment consists of two parts: principal and interest. Early in the loan term, more of your payment goes toward interest. As the loan matures, more goes toward principal.
Capitalization occurs when unpaid interest is added to your principal balance. This typically happens after the grace period ends or when you exit deferment or forbearance. Capitalization increases your principal, meaning you'll pay interest on a larger amount going forward.
| Feature | Subsidized Loans | Unsubsidized Loans |
|---|---|---|
| Based on Financial Need | Yes | No |
| Interest During School | Government pays | You pay (accrues) |
| Interest During Grace Period | Government pays | You pay (accrues) |
| Available to Graduate Students | No | Yes |
| Annual Loan Limits | Lower | Higher |
Federal student loans are provided by the U.S. Department of Education and offer several advantages over private loans, including lower fixed interest rates, income-driven repayment plans, and loan forgiveness programs. More than 90% of student debt in the U.S. is federal.
Direct Subsidized Loans: Available to undergraduate students with financial need. The government pays interest while you're in school at least half-time, during the grace period, and during deferment periods.
Direct Unsubsidized Loans: Available to undergraduate, graduate, and professional students regardless of financial need. Interest accrues from the moment the loan is disbursed.
Direct PLUS Loans: Available to graduate students and parents of dependent undergraduates. These have higher interest rates and require a credit check.
Direct Consolidation Loans: Allow you to combine multiple federal loans into a single loan with one monthly payment.
Private student loans come from banks, credit unions, and online lenders. They typically have higher interest rates than federal loans and offer fewer borrower protections. However, they can be useful when federal loans don't cover all educational costs.
Many states offer their own student loan programs through state agencies or non-profit organizations. These often include forgiveness programs for students who remain in-state after graduation, particularly for careers in teaching, nursing, or public service.
Federal student loans offer several repayment plans designed to fit different financial situations. Here's a comparison of the major options:
| Plan | Loan Length | Monthly Payment | Who Qualifies | Forgiveness? |
|---|---|---|---|---|
| Standard | 10 years | Fixed | All borrowers | No |
| Graduated | 10 years | Increases every 2 years | All borrowers | No |
| Extended | 25 years | Fixed or graduated | Loans over $30,000 | No |
| Income-Based (IBR) | 20-25 years | 10-15% of discretionary income | Partial financial hardship | Yes |
| Pay As You Earn (PAYE) | 20 years | 10% of discretionary income | New borrowers after 2007 | Yes |
| Revised PAYE | 20-25 years | 10% of discretionary income | Any Direct Loan borrower | Yes |
| Income-Contingent (ICR) | 25 years | 20% of discretionary income | Any Direct Loan borrower | Yes |
Note: Public Service Loan Forgiveness (PSLF) forgives remaining balances after 120 qualifying payments (10 years) for borrowers working full-time in public service jobs.
Even small extra payments can dramatically reduce your total interest and shorten your repayment period. Use our repayment calculator to see how much you could save by paying just $50 or $100 extra per month.
If you have unsubsidized loans, paying interest while still in school prevents it from capitalizing (being added to your principal balance) after graduation. This can save you significant money over time.
Many lenders offer a 0.25% interest rate reduction for enrolling in automatic payments. This small discount can add up over the life of your loan.
If you have private student loans with high interest rates and good credit, refinancing could lower your rate. However, never refinance federal loans into private ones, as you'll lose important borrower protections.
If you have multiple loans, consider the debt avalanche method: make minimum payments on all loans, then put any extra money toward the loan with the highest interest rate.
Tax refunds, bonuses, gifts, and other unexpected money can be used to make lump-sum payments that directly reduce your principal.
If your federal loan payments are unaffordable, an income-driven repayment plan can cap your payments at a percentage of your income. After 20-25 years, any remaining balance may be forgiven.
It's tempting to borrow the maximum amount offered, but remember that every dollar borrowed must be repaid with interest. Only borrow what you truly need for tuition, fees, and essential living expenses.
Not all student loans are created equal. Compare interest rates carefully. Even a 1% difference can mean thousands of dollars over the life of your loan.
Missing a student loan payment can damage your credit score and lead to default. If you're struggling, contact your loan servicer immediately to discuss options like deferment, forbearance, or income-driven repayment.
Take time to understand your repayment plan options. The default standard plan may not be the best fit for your financial situation.
Unpaid interest that capitalizes can significantly increase your loan balance. Pay interest during school and grace periods if possible to prevent this.
While refinancing can lower your interest rate, converting federal loans to private loans means losing access to income-driven repayment, forgiveness programs, and other federal protections.
If you work in public service, education, healthcare, or other qualifying fields, you may be eligible for loan forgiveness. Don't miss out on these opportunities.
Subsidized loans are based on financial need, and the government pays the interest while you're in school, during the grace period, and during deferment. Unsubsidized loans are available regardless of need, but interest accrues from the day the loan is disbursed, and you're responsible for paying it.
Student loan interest is typically calculated using a daily interest formula. The annual interest rate is divided by 365 to get the daily rate, which is then multiplied by your outstanding principal balance. Each month, the accumulated daily interest is charged, and any payment first goes toward interest before reducing principal.
Yes! All federal student loans and most private student loans allow penalty-free early repayment. There are no prepayment penalties on federal student loans, so you can pay as much extra as you want without any fees.
If you have federal loans and can't afford payments, you have several options: income-driven repayment plans, deferment, or forbearance. Income-driven plans cap payments based on your income and family size. Deferment and forbearance temporarily pause payments, but interest may continue to accrue.
Yes, you may be able to deduct up to $2,500 of student loan interest paid during the year, subject to income limits. The deduction phases out for single filers with modified adjusted gross income between $75,000 and $90,000, and for joint filers between $155,000 and $185,000.
A common rule of thumb is to keep total student loan debt below your expected first-year salary after graduation. Another guideline suggests that your monthly student loan payment shouldn't exceed 8-10% of your gross monthly income. Our projection calculator can help you estimate your future payments to make this assessment.
This depends on your interest rate and expected investment returns. Generally, if your student loan interest rate is higher than what you expect to earn from investments (after accounting for risk), paying off loans is better. However, you should always contribute enough to get any employer 401(k) match first, as that's essentially free money.
It's very difficult but not impossible. You must prove "undue hardship" in an adversarial proceeding, which requires showing that you cannot maintain a minimal standard of living, your hardship will persist for most of the repayment period, and you've made good-faith efforts to repay. Few bankruptcy filers succeed in discharging student loans.
The average federal student loan debt is approximately $37,000, though this varies significantly by degree type, institution, and state. Graduate and professional degrees often carry much higher debt loads. Overall, Americans owe more than $1.7 trillion in student loans.
You can change your federal student loan repayment plan at any time by contacting your loan servicer. There's no limit to how many times you can switch plans, though it's best to choose a plan that fits your long-term financial situation.
