How to Use This Student Loan Calculator

Step-by-Step Guide

Follow these steps to compare repayment plans and find your optimal strategy

1

Enter Your Student Loans

Add each of your student loans individually with the current balance, interest rate, and loan type (subsidized, unsubsidized, PLUS, or private). You can find this information on your loan servicer's website or at StudentAid.gov for federal loans. Click "Add Loan" to include multiple loans.

2

Choose a Repayment Plan

Select your preferred repayment plan from the dropdown. For income-driven plans, enter your annual income, family size, and tax filing status so the calculator can estimate your monthly payment based on discretionary income formulas.

3

Configure Forgiveness Options

Toggle PSLF if you work for a qualifying public service employer, or Teacher Loan Forgiveness if you teach in a qualifying school. Set the forgiveness timeline to see how each option affects your total cost and the amount that could be forgiven.

4

Compare Plans and Total Costs

Review the plan comparison panel to see monthly payments, payoff timelines, total interest, and forgiveness amounts side by side. Click on any plan to view its detailed breakdown. Add extra monthly payments to see how accelerated payoff affects each plan.

Understanding Your Results

What each metric in the plan comparison means

Monthly Payment

The amount you pay each month under the selected plan. For income-driven plans, this is based on your current income and may change annually as your income is recertified. Standard plan payments are fixed for the life of the loan.

Payoff Time

The total number of months or years until your loan is fully repaid or forgiven. Standard plans are 10 years, extended plans up to 25 years, and IDR plans can extend to 20-25 years before forgiveness kicks in.

Total Interest

The cumulative interest paid over the life of the loan. Longer repayment terms and lower monthly payments result in more total interest. IDR plans often have the highest total interest because of extended timelines, but forgiveness can offset this.

Forgiven Amount

The remaining balance forgiven after completing the required number of payments. Under PSLF, this amount is tax-free. Under IDR forgiveness (20-25 years), the forgiven amount may be treated as taxable income, which could result in a significant tax bill in the year of forgiveness.

Understanding Student Loan Repayment Plans

Federal student loans offer multiple repayment plans, each designed for different financial situations. Choosing the right plan can mean the difference between manageable payments and financial strain, or between paying tens of thousands in interest and qualifying for loan forgiveness. Understanding how each plan calculates your monthly payment is essential to making an informed decision.

Standard Repayment Plan (10 Years)

The Standard Repayment Plan is the default for all federal student loans. It divides your total balance into 120 equal monthly payments over 10 years. Your payment is fixed and includes both principal and interest from the first month. This plan results in the lowest total interest cost of any repayment option because the repayment period is shortest. For a $30,000 loan at 5% interest, the standard monthly payment is approximately $318, and you pay about $8,184 in total interest. The standard plan is ideal if you can afford the payments and want to minimize your total cost.

Graduated Repayment Plan (10 Years)

The Graduated Repayment Plan also has a 10-year term, but payments start low and increase every two years. Initial payments may be as low as interest-only, then rise to cover both principal and interest. This plan is designed for borrowers who expect their income to increase steadily over time, such as recent graduates entering professions with predictable salary growth. The downside is that you pay more total interest than the standard plan because you are paying less principal in the early years. For a $30,000 loan at 5%, total interest might be $10,000-$11,000 compared to $8,184 on standard.

Extended Repayment Plan (25 Years)

The Extended Repayment Plan stretches payments over 25 years with either fixed or graduated payment amounts. You must have more than $30,000 in outstanding Direct Loans to qualify. Monthly payments are significantly lower than the standard plan, but total interest is dramatically higher due to the extended term. For a $50,000 loan at 5%, the extended plan drops the monthly payment from about $530 to $290, but total interest increases from $13,640 to approximately $37,500. This plan makes sense only if you cannot afford standard payments and do not qualify for income-driven plans.

Income-Driven Repayment (IDR) Plans

Income-driven repayment plans base your monthly payment on your income and family size rather than your loan balance. There are four main IDR plans: Income-Based Repayment (IBR) caps payments at 10-15% of discretionary income with forgiveness after 20-25 years. Pay As You Earn (PAYE) caps payments at 10% of discretionary income with forgiveness after 20 years, but is only available to newer borrowers. SAVE (formerly REPAYE) sets payments at 5-10% of discretionary income with the most generous income protection and no interest capitalization. Income-Contingent Repayment (ICR) uses the lesser of 20% of discretionary income or a 12-year fixed payment, with forgiveness after 25 years. For most borrowers, SAVE offers the lowest payments and best terms, making it the default recommendation for income-driven repayment.

Federal vs Private Student Loans

Federal Student Loans

Federal student loans are issued by the U.S. Department of Education and come with significant borrower protections that private loans do not offer. Interest rates are set by Congress and are fixed for the life of the loan, currently ranging from about 5-8% depending on the loan type. Federal loans offer access to all income-driven repayment plans, deferment and forbearance options during financial hardship, and eligibility for forgiveness programs like PSLF.

Direct Subsidized Loans are available only to undergraduates with demonstrated financial need. The government pays interest while you are in school, during the 6-month grace period after leaving school, and during deferment periods. Direct Unsubsidized Loans are available to all students regardless of need, but interest accrues from disbursement. Direct PLUS Loans are available to graduate students and parents of undergraduates, carry higher interest rates, and require a credit check (though the criteria are more lenient than private loans).

Private Student Loans

Private student loans are offered by banks, credit unions, and online lenders. Interest rates can be fixed or variable and are based on your credit score and income (or your cosigner's). Rates for well-qualified borrowers may be lower than federal loan rates, but borrowers with limited credit history may face rates of 10% or higher. Private loans typically require a creditworthy cosigner for students without established credit.

The key disadvantage of private loans is the lack of federal protections. Private loans are not eligible for income-driven repayment plans, PSLF, or other federal forgiveness programs. Deferment and forbearance options are limited and vary by lender. If you experience financial hardship, your options are significantly more restricted with private loans. For this reason, financial advisors strongly recommend exhausting federal loan options before turning to private lenders. Private loans should be considered supplemental funding for costs that exceed federal loan limits.

Student Loan Forgiveness Programs

Student loan forgiveness programs can eliminate some or all of your remaining balance after meeting specific requirements. Understanding the available programs and their eligibility criteria is critical because the right combination of repayment plan and forgiveness program can save you tens or even hundreds of thousands of dollars.

Public Service Loan Forgiveness (PSLF)

PSLF forgives the remaining balance on Direct Loans after 120 qualifying monthly payments (10 years) made while working full-time for a qualifying public service employer. Qualifying employers include federal, state, local, and tribal government organizations, 501(c)(3) nonprofit organizations, and certain other nonprofit entities that provide qualifying public services. You must be enrolled in an income-driven repayment plan (or the standard 10-year plan, though this would leave nothing to forgive). The amount forgiven under PSLF is not treated as taxable income, making it one of the most valuable forgiveness programs available. Submit your Employment Certification Form annually to track your qualifying payments.

Income-Driven Repayment Forgiveness

All income-driven repayment plans offer forgiveness of the remaining balance after 20-25 years of qualifying payments, depending on the specific plan. Under IBR for new borrowers and PAYE, forgiveness comes after 20 years. Under ICR and IBR for older borrowers, forgiveness comes after 25 years. The SAVE plan offers forgiveness after as few as 10 years for borrowers with small original balances. Unlike PSLF, the forgiven amount under IDR forgiveness has historically been treated as taxable income, meaning you could owe income tax on the forgiven balance. However, through 2025, there is a temporary exemption making IDR forgiveness tax-free at the federal level.

Teacher Loan Forgiveness

Teachers who work full-time for five consecutive years at a low-income school or educational service agency may qualify for forgiveness of up to $17,500 on Direct Loans. Highly qualified math, science, and special education teachers can receive the full $17,500, while other teachers qualify for up to $5,000. This program can be combined with PSLF — you can use Teacher Loan Forgiveness for the first five years and then continue toward PSLF for the remaining five years. The forgiven amount is not taxable income.

Strategies to Pay Off Student Loans Faster

Repayment Acceleration Methods

  • Avalanche method. Pay minimums on all loans and direct extra money toward the loan with the highest interest rate. Once that loan is paid off, roll the payment into the next-highest-rate loan. This method minimizes total interest paid and is mathematically optimal.
  • Snowball method. Pay minimums on all loans and direct extra money toward the smallest balance first. Once paid off, roll that payment into the next-smallest balance. While not mathematically optimal, the psychological wins from eliminating individual loans can help maintain motivation.
  • Make extra payments consistently. Even $50-$100 extra per month can shave years off your repayment timeline. When making extra payments, specify that they should be applied to principal, not advanced toward future payments. Most servicers allow you to set this preference online.
  • Use windfalls strategically. Apply tax refunds, bonuses, and other unexpected money toward your student loans. A single $3,000 tax refund applied to principal can save you $1,500 or more in interest over the life of the loan.

Refinancing and Other Strategies

  • Refinancing private loans. If you have good credit and stable income, refinancing private student loans can lower your interest rate significantly. Unlike federal loans, you do not lose any special protections by refinancing private loans. Compare rates from multiple lenders, as rate offers can vary by 2-3% for the same borrower.
  • Federal loan refinancing trade-offs. Refinancing federal loans into private loans can lower your rate, but you permanently lose IDR plans, PSLF eligibility, deferment options, and all other federal protections. Only consider this if you have a high income, excellent credit, no interest in forgiveness, and can secure a rate at least 1-2% lower.
  • Employer repayment assistance. A growing number of employers offer student loan repayment as a benefit, typically $100-$300 per month. Ask your HR department if this benefit is available. Under current tax law, employers can contribute up to $5,250 per year toward employee student loans tax-free.
  • Student loan interest deduction. You can deduct up to $2,500 in student loan interest annually on your federal tax return, even if you do not itemize. This deduction phases out at higher income levels ($75,000-$90,000 for single filers), but for qualifying borrowers, it provides meaningful tax savings that can be redirected toward extra loan payments.

Frequently Asked Questions

What is the difference between subsidized and unsubsidized student loans?

Subsidized loans are available to undergraduate students with demonstrated financial need, and the federal government pays the interest while you are enrolled at least half-time, during the grace period, and during deferment. Unsubsidized loans are available to both undergraduate and graduate students regardless of financial need, but interest accrues from the day the loan is disbursed. This means unsubsidized loans cost more over time because interest accumulates during school and capitalizes (is added to the principal) when repayment begins.

How do income-driven repayment plans work?

Income-driven repayment (IDR) plans set your monthly payment as a percentage of your discretionary income, typically 10-20%, rather than basing it on your loan balance. Discretionary income is calculated as the difference between your adjusted gross income and 150% of the federal poverty guideline for your family size and state. If your income is low enough, your payment can be as low as $0 per month. After 20-25 years of qualifying payments (depending on the plan), any remaining balance is forgiven, though the forgiven amount may be taxable as income.

What is Public Service Loan Forgiveness (PSLF)?

PSLF forgives the remaining balance on your Direct Loans after you make 120 qualifying monthly payments (10 years) while working full-time for a qualifying employer, which includes government organizations at any level, 501(c)(3) nonprofits, and certain other public service organizations. You must be on an income-driven repayment plan or the standard 10-year plan to qualify. Unlike IDR forgiveness, the amount forgiven under PSLF is not taxable as income. The program has become more accessible since the 2022 reforms that loosened some eligibility requirements.

Should I refinance my federal student loans?

Refinancing federal student loans into a private loan can lower your interest rate, potentially saving thousands in interest, but you permanently lose access to federal benefits including income-driven repayment plans, PSLF eligibility, deferment and forbearance options, and any future federal forgiveness programs. Refinancing generally makes sense only if you have a stable, high income, excellent credit, no plans to use IDR or PSLF, and can secure a significantly lower rate. If there is any chance you might need federal protections, keep your federal loans as they are.

What happens to student loans during deferment or forbearance?

During deferment, you temporarily stop making payments. On subsidized loans, the government continues paying the interest, so your balance does not grow. On unsubsidized loans and PLUS loans, interest continues to accrue and capitalizes when deferment ends, increasing your total balance. Forbearance also pauses payments, but interest accrues on all loan types. Forbearance is easier to qualify for but costs more in the long run. Both options are meant for temporary financial hardship and should not be used as a long-term strategy because the accruing interest can significantly increase your total repayment amount.

How is interest capitalized on student loans?

Interest capitalization occurs when unpaid accrued interest is added to your principal balance, and you then start paying interest on the larger amount. This happens at specific events: when you enter repayment after the grace period, when deferment or forbearance ends, when you leave an IDR plan, or when you consolidate. For example, if you have a $30,000 loan that accrues $3,000 in interest during school, capitalization increases your principal to $33,000, and all future interest is calculated on this higher amount. This compounding effect can add thousands to your total repayment cost.

Can I change my repayment plan after I start paying?

Yes, you can change your federal student loan repayment plan at any time by contacting your loan servicer. There is no fee to switch plans, and you can switch as often as needed. However, switching plans can have consequences: if you move from an IDR plan to a standard plan, any progress toward IDR forgiveness resets. If you switch between IDR plans, your qualifying payment count may or may not transfer depending on the specific plans involved. Switching from standard to an IDR plan does not reset your PSLF payment count if those payments were qualifying.

What is the SAVE plan and how does it work?

The SAVE (Saving on a Valuable Education) plan replaced the REPAYE plan and is the newest income-driven repayment option. SAVE calculates payments at 5% of discretionary income for undergraduate loans and 10% for graduate loans, using an updated formula that protects more of your income. Unlike other IDR plans, unpaid interest does not capitalize under SAVE, meaning your balance will not grow if your payment does not cover the monthly interest. Borrowers with original balances of $12,000 or less receive forgiveness after just 10 years of payments, with each additional $1,000 borrowed adding one year.
