Student Loan Repayment Plans Compared

With the average student loan borrower owing over $37,000, choosing the right repayment plan can save you thousands of dollars — or cost you thousands more in interest. The federal student loan system offers several repayment options, and the best choice depends on your income, career trajectory, and financial goals.

Here’s a detailed comparison of every federal student loan repayment plan so you can make an informed decision.

How Student Loan Interest Works

Before comparing plans, it’s essential to understand how interest accrues on student loans, because this is what makes certain plans far more expensive than others.

Simple Daily Interest

Federal student loans use simple daily interest. Each day, interest accrues based on this formula:

Daily interest = (Outstanding principal balance x Interest rate) / 365.25

For a $30,000 loan at 5.5% interest:

• Daily interest = ($30,000 x 0.055) / 365.25 = $4.51 per day
• Monthly interest = $4.51 x 30 = $135.37

If your monthly payment is $300, only $164.63 goes toward principal in the first month. The rest covers interest.

The Impact of Payment Size

This is the critical concept: the less you pay each month, the more interest accumulates, and the more you pay over the life of the loan. Plans with lower monthly payments almost always result in higher total costs because you’re paying interest for a longer period and reducing principal more slowly.

The Standard Repayment Plan

How It Works

• Monthly payment: Fixed amount calculated to pay off the loan in exactly 10 years (120 payments)
• Term: 10 years
• Minimum payment: $50/month

Example: $30,000 at 5.5%

• Monthly payment: $326
• Total paid over 10 years: $39,086
• Total interest: $9,086

Who It’s Best For

The Standard plan is the best option for borrowers who can afford the monthly payment. It minimizes total interest paid and gets you out of debt in 10 years. This is the default plan — if you don’t choose otherwise, this is what you’ll be enrolled in.

The Extended Repayment Plan

How It Works

• Monthly payment: Fixed or graduated amount over a longer term
• Term: Up to 25 years
• Eligibility: Must owe more than $30,000 in Direct Loans
• Payment: Can be fixed or graduated

Example: $30,000 at 5.5% (Fixed Extended)

• Monthly payment: $184
• Total paid over 25 years: $55,200
• Total interest: $25,200

The Trade-Off

The monthly payment drops by $142 compared to the Standard plan, but you pay $16,114 more in total interest. That’s the price of stretching the repayment period from 10 to 25 years.

Who It’s Best For

Borrowers who need a lower monthly payment than the Standard plan offers but earn too much for income-driven plans. It’s a straightforward way to reduce your monthly obligation, though you should understand the long-term cost.

The Graduated Repayment Plan

How It Works

• Monthly payment: Starts low and increases every two years
• Term: 10 years
• Payment increases: Every 24 months, payments increase by a set amount
• Initial payment: Can be as low as the interest-only amount

Example: $30,000 at 5.5%

• Starting payment: approximately $188
• Ending payment: approximately $564
• Total paid over 10 years: approximately $41,400
• Total interest: approximately $11,400

The Theory

The Graduated plan assumes your income will grow over time. You pay less when you’re starting your career and more as your earning power increases. Payments are still structured to pay off the loan in 10 years.

Who It’s Best For

Early-career professionals who expect significant salary growth. Medical residents, lawyers starting at firms, or anyone in a field with a steep earnings trajectory may benefit from the lower initial payments. Use our Paycheck Calculator to estimate your net income at different salary levels.

However, if your income doesn’t grow as expected, the increasing payments can become a burden. And you pay about $2,300 more in interest compared to the Standard plan because less principal is paid in the early years.

Income-Driven Repayment Plans

Income-driven repayment (IDR) plans tie your monthly payment to your income and family size. There are several variants — use our income-based repayment calculator to estimate your payment under each one.

SAVE Plan (Saving on a Valuable Education)

This is the newest IDR plan, replacing the older REPAYE plan:

• Payment: 5% of discretionary income for undergraduate loans, 10% for graduate loans
• Discretionary income: Income above 225% of the federal poverty line
• Term: 20 years (undergraduate) or 25 years (graduate)
• Forgiveness: Remaining balance forgiven after the term
• Interest benefit: If your payment doesn’t cover interest, the government covers the difference (no interest capitalization)

IBR (Income-Based Repayment)

• Payment: 10% of discretionary income (new borrowers after July 2014) or 15% (older borrowers)
• Discretionary income: Income above 150% of poverty line
• Term: 20 years (new borrowers) or 25 years (older borrowers)
• Forgiveness: Remaining balance forgiven after the term

PAYE (Pay As You Earn)

• Payment: 10% of discretionary income
• Discretionary income: Income above 150% of poverty line
• Term: 20 years
• Cap: Payment never exceeds what you’d pay on Standard plan
• Eligibility: Must be a new borrower as of Oct 1, 2007

ICR (Income-Contingent Repayment)

• Payment: 20% of discretionary income or fixed payment over 12 years, whichever is less
• Term: 25 years
• Note: This is the least favorable IDR plan and is primarily used by Parent PLUS borrowers (after consolidation)

IDR Example: $30,000 at 5.5%, $45,000 Income

Under the SAVE plan for an undergraduate borrower:

• Poverty line (single): approximately $15,650
• 225% of poverty line: $35,213
• Discretionary income: $45,000 - $35,213 = $9,788
• Annual payment: $9,788 x 5% = $489
• Monthly payment: approximately $41

That’s dramatically lower than the Standard plan’s $326, but you’ll be paying for up to 20 years, and interest accumulates rapidly at that payment level.

Comparing Total Costs

Here’s a side-by-side comparison for a $30,000 loan at 5.5%:

Plan	Monthly Payment	Term	Total Paid	Total Interest
Standard	$326	10 years	$39,086	$9,086
Extended (Fixed)	$184	25 years	$55,200	$25,200
Graduated	$188–$564	10 years	$41,400	$11,400
SAVE ($45K income)	$41+	20 years	Varies*	Varies*

*IDR total cost depends heavily on income growth. If your income rises significantly, payments increase and you may pay off the loan before forgiveness. If income stays low, you may pay far less than the balance — but the forgiven amount may be taxable income.

Forgiveness and Tax Implications

Under IDR plans, any remaining balance after the repayment period (20 or 25 years) is forgiven. Under current law (through 2025), this forgiven amount is not treated as taxable income. However, this tax-free treatment is set to expire, and forgiven balances after that may be subject to income tax — potentially pushing you into a higher bracket in the year of forgiveness. For the latest on forgiveness programs, see our guide on student loan forgiveness in 2026.

Additionally, Public Service Loan Forgiveness (PSLF) offers forgiveness after just 10 years of qualifying payments while working for a government or nonprofit employer. PSLF forgiveness is always tax-free.

Strategies for Paying Less Overall

1. Pay More Than the Minimum

Even small additional payments can save thousands in interest. On a $30,000 loan at 5.5% on the Standard plan, paying an extra $50/month saves about $2,100 in interest and pays off the loan 18 months early.

2. Target High-Interest Loans First

If you have multiple loans, direct extra payments to the highest-rate loan while making minimum payments on the rest (the “avalanche method”). This minimizes total interest paid.

3. Refinance When It Makes Sense

If you have strong credit and a stable income, refinancing federal loans with a private lender at a lower rate can save money. But you lose access to IDR plans, forgiveness programs, and federal protections. Only refinance if you’re confident you won’t need those benefits.

4. Automate Payments

Most federal servicers offer a 0.25% interest rate reduction when you enroll in autopay. It’s small but free.

Which Plan Should You Choose?

Choose Standard if: You can afford the payments and want to minimize total interest. This is the mathematically optimal plan for most borrowers.

Choose Graduated if: You’re early in a career with strong growth potential and need lower payments now but can handle increasing payments.

Choose Extended if: You need a lower fixed payment and don’t qualify for or want IDR plans.

Choose SAVE/IDR if: Your income is low relative to your debt, you work in public service (PSLF eligible), or you expect forgiveness to save you money over the long term.
