Default rate is the 2026–27 federal undergraduate rate. RAP charges 1%–10% of adjusted gross income, minus $50 a month per dependent ($10 minimum). IBR shown for borrowers whose first loan was on or after July 1, 2014: 10% of income above 150% of the 2026 poverty guideline for your household, capped at the 10-year standard payment. Estimates only; the Loan Simulator at studentaid.gov uses your actual loans.

How the Calculator Works

  • Monthly payment: a fixed payment that pays off the balance over your chosen term.
  • Extra payments: added every month until the loan is paid off. Federal and most private loans allow extra payments with no penalty.
  • New standard plan: for loans made on or after July 1, 2026, the term is set by your balance: under $25,000, 10 years; $25,000–$49,999, 15 years; $50,000–$99,999, 20 years; $100,000 or more, 25 years.
  • RAP: 1% to 10% of adjusted gross income depending on how much you earn, minus $50 a month for each dependent, with a $10 minimum. RAP does not depend on your balance.
  • IBR: for borrowers whose first loan was on or after July 1, 2014 and whose loans predate July 2026: 10% of income above 150% of the poverty guideline for your household, capped at the 10-year standard payment.

Impact of Extra Payments

$30,000 at 6.52% on a 10-year plan:

Extra Payment Monthly Total Payoff Time Total Interest Interest Saved
$0 (standard) $341 10 years $10,914 —
+$50 $391 8 years, 4 months $8,921 $1,992
+$100 $441 7 years, 2 months $7,555 $3,359
+$200 $541 5 years, 7 months $5,796 $5,118
+$300 $641 4 years, 7 months $4,711 $6,203
+$500 $841 3 years, 4 months $3,439 $7,475

An extra $100 a month saves about $3,400 in interest and nearly 3 years of payments. If you’re on the new standard plan with a 15- or 20-year term, extra payments save even more.

Income-Driven Estimates

Adjusted gross income RAP (no dependents) RAP (2 dependents) IBR (single)
$30,000 $50 $10 $51
$50,000 $167 $67 $217
$75,000 $438 $338 $426
$100,000 $750 $650 $634

IBR amounts are capped at the 10-year standard payment on your balance. IBR for a larger household uses a higher poverty line, so the payment is lower. SAVE has ended; see income-driven repayment plans for which plans you can use.

Paying Off Multiple Loans: Avalanche vs Snowball

Debt Avalanche (Highest Interest First)

Loan Balance Rate Priority
Private loan $15,000 8.5% Pay first
Grad PLUS $25,000 7.0% Second
Undergrad (unsubsidized) $15,000 5.5% Third
Undergrad (subsidized) $10,000 4.5% Last

Debt Snowball (Smallest Balance First)

Loan Balance Rate Priority
Undergrad (subsidized) $10,000 4.5% Pay first
Undergrad (unsubsidized) $15,000 5.5% Second
Private loan $15,000 8.5% Third
Grad PLUS $25,000 7.0% Last

Pay the minimum on every loan and put any extra toward the top of the list. The avalanche saves the most money; the snowball gives faster wins. If you’re pursuing PSLF, don’t prepay federal loans at all: extra payments only reduce what would be forgiven.

Refinancing Student Loans

Factor Federal Loans Refinanced (Private)
Rate Fixed, set yearly by formula Fixed or variable, set by credit
Income-driven plans Yes (RAP, IBR) No
PSLF eligible Yes No
Forbearance/deferment Yes Limited
Interest deduction Up to $2,500/year Up to $2,500/year

Refinance private loans whenever you can get a lower rate. Refinance federal loans only if you have stable high income, won’t pursue PSLF and won’t need income-driven payments. See how to refinance student loans.

Student Loan Interest Deduction (2026)

Filing Status Max Deduction Phase-Out Starts Fully Phased Out
Single $2,500 $85,000 MAGI $100,000
Married filing jointly $2,500 $175,000 MAGI $205,000
Tax Bracket Max Deduction Annual Tax Savings
12% $2,500 $300
22% $2,500 $550

Phase-out ranges from IRS Rev. Proc. 2025-32. The 24% bracket starts above both phase-out limits, so the deduction is worth at most about $550 in federal tax.

Student Loans vs Other Financial Goals

Your Loan Rate Usual Strategy
Under 5% Invest more, pay the minimum on loans
5–7% Split extra money between investing and the loans
Over 7% Prioritize loan payoff
Any rate, with an employer 401(k) match Always get the full match first

Key Takeaways

  1. 10-year standard plan on $30,000 at 6.52% = $341/month and $10,914 total interest
  2. New loans from July 2026 default to a 10–25 year standard plan based on balance; paying on a 10-year schedule still saves the most interest
  3. Extra $100/month on $30,000 saves about $3,400 and nearly 3 years
  4. RAP charges 1%–10% of income: about $167/month at $50,000 with no dependents
  5. PSLF forgives the remaining balance, tax-free, after 120 qualifying payments at a government or nonprofit job; see how to apply for PSLF
  6. Don’t refinance federal loans if you’re pursuing PSLF or might need income-driven repayment
  7. Get your full employer 401(k) match before making extra loan payments
