Student loan repayment tools, step by step

These student loan repayment tools help you understand what you owe and how to pay it down. Estimate payments on each loan, see how much of every payment goes to interest, weigh consolidation, test the effect of extra or more frequent payments, and estimate the interest deduction. If you are saving for a child's education instead, the last step looks ahead to college savings.

Who is this collection for?

Graduates entering repayment, borrowers already paying who want to finish sooner, and parents planning ahead. It works for federal and private loans, though federal loans come with plan options and protections that the calculators do not model.

Gather each loan's balance, interest rate and type. Your Federal Student Aid account lists your federal loans; private loans appear on your statements and credit report.

Step by step

What order should you work through?

  1. Estimate each payment

    Use the student loan calculator for a payment and total interest on each loan.

  2. See where the money goes

    Use the loan payment breakdown calculator to see how much of each payment is interest versus principal.

  3. Weigh consolidation

    Use the student loan consolidation calculator to see the weighted-average rate and how a longer term changes total cost.

  4. Test faster payoff

    Use the payment frequency and accelerated payoff calculators to see what biweekly or extra payments save.

  5. Estimate the tax benefit

    Use the loan interest tax deduction calculator to estimate what the student loan interest deduction might be worth.

What should you know before changing your plan?

  • Which loans are federal and which are private
  • Each loan's rate and whether it is fixed or variable
  • Your servicer for each federal loan
  • Whether any interest has been or will be capitalized
  • That refinancing federal loans into a private loan ends federal plan options

Saving for a child's education instead?

The college savings calculator estimates how much to set aside each month to reach a target by a given year. Starting early reduces the monthly amount because compounding has longer to work.

Federal Student Aid explains how financial aid works, and its own tools are the authoritative source for federal loan rates and repayment plans.

Frequently asked questions

How is federal student loan consolidation interest calculated?

A Direct Consolidation Loan uses the weighted average of the rates on the loans you combine, rounded up to the nearest one-eighth of a percent. It does not lower your rate, but it can simplify payments and change your term. The consolidation calculator shows the resulting rate and total cost.

Does paying student loans biweekly save money?

It can. Paying half your monthly amount every two weeks adds up to 13 full payments a year instead of 12, which reduces principal sooner and cuts total interest. Check with your servicer that extra amounts are applied to principal rather than held for the next due date.

What is capitalized interest on a student loan?

Capitalized interest is unpaid interest that is added to your principal balance, after which you pay interest on it too. It can happen after certain periods such as deferment or forbearance. Paying interest as it accrues, when you can, prevents your balance from growing.

Is student loan interest tax-deductible?

You may be able to deduct some of the interest you paid on qualified student loans, subject to income limits and an annual cap set by the IRS. The loan interest tax deduction calculator gives an estimate; IRS guidance and a tax professional can confirm your situation.

Should I put extra money toward my student loans?

It depends on your rates, other debts and savings. Extra payments on a higher-rate loan save more interest than on a lower-rate one. Many people make sure they have an emergency fund first. The accelerated payoff calculator shows the interest and time saved.

Do these calculators show income-driven repayment payments?

No. They model standard fixed payments. Income-driven plans set payments based on income and family size under federal rules. Your Federal Student Aid account and servicer are the authoritative sources for those amounts. Use our calculators to understand standard payments and total interest, then compare with the plan amounts your servicer gives you.

Does refinancing federal student loans have downsides?

Refinancing federal loans with a private lender replaces them with a private loan, so you lose access to federal options such as income-driven repayment and federal deferment. A lower rate may save interest, but weigh it against the protections you give up.

How much should I save each month for a child's college?

It depends on your target amount, years until college, and the return you assume. The college savings calculator works backward from a goal to a monthly figure. Starting earlier lowers that amount noticeably. Rerun it each year as your balance and timeline change, since the required monthly amount moves with them.
