Use the Federal Student Aid Repayment Calculator to compare plans available for your loans, then record each estimate’s monthly payment, principal paid, interest paid, total paid, repayment or discharge date, and any estimated discharge. A smaller payment can mean a longer repayment period and more interest over time; it does not automatically mean a cheaper loan.
The calculator provides estimates, not a binding payment quote. Your loan servicer determines and communicates final terms after processing your application. Eligibility, loan details, income, and household circumstances affect which plans and estimates apply to you.

What to compare: the monthly bill and the full repayment outcome
Standard repayment and IDR answer different affordability questions. Standard repayment generally spreads payments over a fixed term. IDR options base payments on borrower circumstances and may produce lower bills for some borrowers, but the repayment timeline and total cost can differ. The useful comparison is not simply “Which payment is smaller?” It is “What payment can I manage, what will I pay in total, and what happens to any remaining balance?”

The Federal Student Aid Repayment Calculator estimates monthly payment, principal paid, interest paid, total amount paid, possible discharge, and an end-of-term date. It also lets you sort results by low monthly payment, low total paid, or fastest payoff. Review the underlying figures rather than relying on a sort order: each one reflects a different priority.
#1 Best Overall
- Monthly affordability: What is the estimated recurring payment, and can it fit your budget?
- Total cost: How much principal and interest does the estimate show you paying, and what is the total amount paid?
- Time: When does the calculator estimate repayment will end, or discharge may occur?
- Eligibility and conditions: Is the plan available for your specific loans, and does an estimated discharge depend on meeting requirements?
- Uncertainty: Which figures are estimates, and what must your servicer confirm?
Compare the same loans and the same borrower assumptions in every scenario. If you change income, household details, or the loans included between estimates, the results are no longer a like-for-like comparison.
It helps to think of these as separate questions rather than one ranking. A plan can have the lowest monthly payment without having the lowest total paid. Another can have the fastest payoff but require a larger monthly commitment. The calculator’s sorting options help you find estimates that match a priority, but you still need to decide which trade-off matters most for your circumstances.
How Standard repayment differs from IDR
Standard Repayment Plan
Federal Student Aid describes Standard repayment as a fixed-payment plan, generally over 10 years in the typical case. Some consolidation loans have longer terms. A fixed schedule makes the payment and payoff period easier to plan around, but the payment may be less affordable than an income-based option for a borrower with limited income. Your own eligible-plan result and loan terms matter more than the typical term.

In particular, Federal Student Aid notes that some consolidation loans have longer terms. Use the payoff date and payment estimate tied to your own loans, rather than assuming that every Standard plan will end on the same schedule.
Income-driven repayment plans
IDR is a category, not one uniform plan with one payment formula or one set of terms. Federal Student Aid’s current guidance describes IBR, ICR, PAYE, and the Repayment Assistance Plan (RAP) as IDR options, subject to loan eligibility and individual circumstances. Loan type and disbursement dates affect availability; the plans shown as eligible for your loans are the relevant choices.
Federal Student Aid describes RAP payments as a percentage of adjusted gross income, with a dependent-related reduction and a $10 minimum. Confirm the specific eligibility and effective rules shown for your situation in the calculator and with your servicer. Do not assume one IDR plan’s terms apply to another.
Plan availability is date-sensitive. Federal Student Aid says a court order ended the Saving on a Valuable Education (SAVE) Plan in March 2026, and that PAYE and ICR will be retired no later than July 1, 2028. Check your StudentAid.gov account and current Federal Student Aid guidance before choosing a plan; a plan that appears in older articles or calculators may not be an available option for you now.

| Comparison point | Standard repayment | IDR options |
|---|---|---|
| How payments are set | Fixed-payment plan, according to Federal Student Aid. | Depends on the particular plan and borrower circumstances; RAP is described as a percentage of adjusted gross income, with a dependent-related reduction and a $10 minimum. |
| Typical term or endpoint | Generally 10 years; some consolidation loans have longer terms. | Use the end date or repayment period estimated for the specific eligible plan in the calculator. A single term should not be assumed for all IDR options. |
| Availability | Depends on the loan and applicable terms. | Depends on loan types, disbursement dates, and borrower circumstances. Current guidance says SAVE ended in March 2026 and PAYE and ICR will end no later than July 1, 2028. |
| What to compare in the calculator | Monthly payment, principal and interest paid, total paid, and payoff date. | The same figures, plus any estimated discharge and the conditions behind it. |
Do not decide that a plan is available based only on its name or on a general list. Federal Student Aid’s current guidance provides a snapshot of plans, but loan types and disbursement dates affect the options for an individual borrower. Your account and the plan results for your loans are the useful starting points.
How to compare your own estimates
- Start with your federal loan information. Sign in to your StudentAid.gov account and check the loans you need to repay. Loan type and disbursement dates can affect plan eligibility, so do not compare a plan simply because it appears in a general description.
- Open the Federal Student Aid Repayment Calculator. Sign in to import loan and income information where possible. Check that the loans and personal information used in the estimate match the situation you want to evaluate.
- Review the eligible plans it displays. Compare plans actually available for your loans. If an option you expected is absent or you are unsure why a plan appears eligible, confirm the issue with Federal Student Aid or your servicer rather than guessing from a plan name.
- Keep your assumptions consistent. Use the same loans and borrower details for each plan. For scenario analysis, use manual entry to vary income and see how the estimated payment and totals change. Change one assumption at a time so you can tell what drove the difference.
- Record the results that answer the whole question. For each plan, note the monthly payment, repayment period or end date, principal paid, interest paid, total paid, and estimated discharge if shown. Include which loans and assumptions the estimate uses.
- Run a separate PSLF view if you are pursuing Public Service Loan Forgiveness. Select PSLF in the calculator and review its adjusted total paid and forgiveness estimate. Federal Student Aid cites 120 qualifying payments for PSLF; an estimate does not establish that you will satisfy the program’s eligibility and qualifying-payment requirements.
- Confirm before acting. Treat the result as an estimate. Your servicer determines and communicates final terms, including the payment amount, after processing an application.
Signing in can help the calculator use loan and income information from your account. Manual entry is useful when you want to test a changed income scenario, but make sure the entries correspond to the scenario you intend to evaluate. If you are testing what might happen under different income assumptions, preserve the baseline result and alter only the income entry for the next run. That makes the difference between the two estimates easier to interpret.
When entering or reviewing results, distinguish plans that apply to all the loans in a scenario from any situation where the eligible loans or details differ. If the calculator presents a plan as available only for certain loans, that is not the same comparison as evaluating repayment of a different loan set. Record the loan coverage alongside the result so you do not later mistake one estimate for another.
Use a comparison worksheet to make trade-offs visible
A small table prevents a low monthly payment from crowding out the other figures. Fill it with the calculator’s estimates for each eligible plan; do not substitute a general plan description for a personalized result.

Pick the symptom - the matching free tool is one click away.
| Figure to record | Why it matters | Your entry |
|---|---|---|
| Plan name and eligibility | Shows which option the estimate covers and whether your loans are eligible. | Record for each plan. |
| Estimated monthly payment | Shows the projected recurring bill, not the full cost of repayment. | Record the calculator’s estimate. |
| Principal paid | Separates repayment of borrowed balance from interest cost. | Record the calculator’s estimate. |
| Interest paid | Shows estimated interest over the modeled repayment period. | Record the calculator’s estimate. |
| Total paid | Provides the broadest estimate of the amount paid under that scenario. | Record the calculator’s estimate. |
| Estimated payoff or discharge date | Shows how long the modeled path lasts and when it ends. | Record the date or period shown. |
| Estimated discharge | Indicates a possible remaining balance discharge, subject to applicable criteria. | Record the estimate and its conditions, if shown. |
| Assumptions | Makes comparisons interpretable if you later revisit or rerun them. | Record the loans and borrower details used. |
After filling in the table, decide which constraint is binding. If the Standard estimate is affordable and your priority is a clear fixed schedule, the term and total-paid estimate may be especially useful. If that payment does not fit your budget, an eligible IDR estimate may offer a more manageable monthly amount, but weigh it against its modeled total, timeline, and any conditional discharge. The calculator can order plans by a priority; it cannot choose the right trade-off for your budget or goals.
A useful reading order is to check eligibility first, then affordability, then the full cost and timeline. An ineligible plan is not a real option to compare. Among eligible plans, a payment that does not fit your budget may not be workable even if its total-paid estimate is appealing. Conversely, a payment that looks manageable should not obscure a longer estimated repayment period or a higher interest and total-paid figure. The result is a set of trade-offs, not a single score.
Keep the worksheet with the date you ran the estimates and the assumptions you used. This is particularly helpful if you revisit the comparison after your income or household circumstances change, or if you check eligibility again as plan availability changes. You can then see whether a new result reflects a changed input, a changed eligible plan set, or both.

Why a lower monthly payment can cost more over time
A lower payment can leave repayment stretched across a longer period. When repayment takes longer, interest may accumulate for longer, so the total paid can be higher even when the monthly bill is lower. That is why a monthly-payment-only comparison can be misleading.
Recommended Free Tools
There is no universal dollar difference between Standard and IDR. The result depends on your balance, interest rates, loan types and dates, income and household details, eligible plans, and whether a discharge path applies. Use calculator estimates based on your own details instead of applying another borrower’s result to your loans.
Also distinguish the figures the calculator reports. Principal paid is not interest paid; total paid is not necessarily the same as the balance borrowed; and possible discharge is not money you have already saved or a guaranteed outcome. Keep all of those figures beside the monthly payment when weighing the plans.
For example, if one estimate shows a smaller monthly amount but a later estimated end date, the difference in timing is part of the trade-off, not a detail to ignore. Check whether the calculator also shows more interest or a larger total paid in that scenario. If it does, that is the modeled cost of choosing that path under the entered assumptions; it is not a universal result for every borrower choosing IDR.
Likewise, a higher monthly payment does not by itself prove that a plan is best for you. The total paid, payoff date, affordability, eligibility, and any conditional discharge all matter. The tool’s options to sort by low monthly payment, low total paid, or fastest payoff are useful ways to locate different results, but the lowest figure in one category does not settle the others.
How to interpret discharge and PSLF estimates
A projected discharge is conditional. Federal Student Aid’s calculator estimates assume the borrower meets the applicable criteria, including making full, on-time payments. A PSLF view reflects its qualifying-payment structure, but a projected forgiveness amount remains an estimate rather than a promise.
If PSLF is part of your decision, use the calculator’s PSLF selection rather than treating a non-PSLF estimate as interchangeable. Federal Student Aid cites 120 qualifying payments for PSLF. Whether your employment, loans, repayment plan, and payments qualify must still be established under the program’s requirements; the calculator’s projection alone does not establish qualification.
For either an IDR discharge estimate or PSLF, consider the endpoint and assumptions alongside the monthly amount and total paid. If your assumptions or eligibility change, the estimate may no longer describe your situation.
In a PSLF comparison, look specifically at the calculator’s adjusted total paid and forgiveness estimate. Those figures answer a different question from a standard repayment estimate without PSLF selected. Keep the two views labeled so you do not compare a projected PSLF outcome with a non-PSLF outcome as if they shared the same assumptions. The 120 qualifying payments figure is a program requirement cited by Federal Student Aid, not a promise that every borrower who makes 120 payments will receive forgiveness; qualifying criteria still apply.
Interest-rate reductions and other assumptions to check
Federal Student Aid says eligible borrowers enrolled in autopay by December 31, 2026, receive a 1% interest-rate reduction through June 30, 2028. This is a dated, eligibility-dependent condition, not a rate reduction every borrower should automatically include. Check eligibility and enrollment details before treating it as part of your personal cost estimate, and note the period it covers.
More generally, identify which assumptions the calculator has imported or which you entered manually. If your income or household information is different from what you intend to model, adjust it and rerun the estimate. A comparison is only as useful as the loan and borrower information behind it.
The autopay reduction has both an enrollment deadline and an end date in Federal Student Aid’s guidance. Do not treat the 1% reduction as a permanent discount or assume you qualify simply because you intend to use autopay. Confirm the enrollment and eligibility conditions that apply to you, and use the calculator or servicer information relevant to your own loans when estimating costs.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Common comparison mistakes
- Choosing the lowest payment without checking total paid. A smaller bill can accompany a longer repayment timeline and more interest. Review the total-paid and interest estimates together.
- Comparing different sets of loans. If one estimate omits a loan or uses different loan details, the plans are not being compared on the same basis.
- Assuming every IDR plan is the same. IDR includes distinct options, and eligibility and terms vary. Compare the specific plans shown for your loans.
- Using outdated plan information. SAVE ended in March 2026, according to Federal Student Aid; PAYE and ICR are scheduled to end no later than July 1, 2028. Recheck current eligibility rather than relying on older plan lists.
- Treating projected discharge as guaranteed. Discharge estimates depend on applicable criteria and the assumptions used. For PSLF, review the separate PSLF estimate and qualifying-payment requirements.
- Treating the calculator result as your approved payment. The tool provides estimates. Your servicer sets final terms after processing your application.
- Changing multiple assumptions at once. If income, household details, and loans all change between scenarios, it becomes difficult to identify why the estimate changed. Vary one factor at a time when testing scenarios.
- Relying on a typical term as if it were yours. Standard repayment is generally described as 10 years, but some consolidation loans have longer terms. Use the estimate for your loan rather than substituting the typical figure.
- Assuming an old plan list is current. Plan status can change. Check current guidance and the plan options shown for your loans rather than building a comparison around a plan that is no longer available.
- Ignoring the purpose of a sort order. Sorting by lowest monthly payment, lowest total paid, or fastest payoff surfaces different priorities. Read the rest of the result before deciding.
When to rerun the comparison
Rerun the calculator when a material input changes, such as your income or household circumstances, or when you need to reassess eligible plans for your loans. Recheck official guidance before making a decision because plan rules and availability can change. If you apply for a plan, use the terms your servicer communicates as the operative payment information rather than continuing to rely on a preliminary calculator estimate.

Frequently Asked Questions
How do I compare IDR and Standard repayment fairly?
Use the Federal Student Aid Repayment Calculator for plans eligible for your loans. Keep the loan set and borrower assumptions consistent, then compare monthly payment, principal paid, interest paid, total paid, payoff or discharge timing, and estimated discharge conditions.
Does a lower income-driven payment mean I will pay less overall?
Not necessarily. A lower payment can extend repayment, allowing interest to accumulate for longer and increasing total paid. Compare the calculator’s interest and total-paid estimates as well as the monthly amount.
Is the Repayment Calculator estimate my approved payment?
No. Federal Student Aid describes calculator results as estimates only. Your loan servicer determines and communicates final terms, including the payment amount, after processing your application.
What IDR plans are currently described by Federal Student Aid?
Current guidance describes IBR, ICR, PAYE, and RAP as IDR options subject to loan eligibility and individual circumstances. Federal Student Aid says SAVE ended in March 2026, and PAYE and ICR will be retired no later than July 1, 2028. Check your account and current eligibility.
Can I count on estimated discharge or PSLF forgiveness?
No. Discharge estimates depend on applicable criteria, including full, on-time payments. A PSLF calculator view reflects its qualifying-payment structure and cites 120 qualifying payments, but the projection does not establish that your employment, loans, plan, and payments qualify.
What does Standard repayment usually mean for repayment length?
Federal Student Aid describes Standard repayment as generally lasting 10 years, with longer terms for some consolidation loans. Use the estimate for your own loans to see the applicable payment and payoff date.
The Bottom Line
Compare eligible plans using the Federal Student Aid Repayment Calculator, but judge more than the monthly bill. Put the payment beside interest, total paid, payoff or discharge timing, eligibility, and any conditions attached to estimated discharge. A lower payment may mean more time and more interest; estimates are not final terms, so confirm your plan and payment with your servicer.
