Student Loan Calculator: Estimate Monthly Payments, Interest & Total Repayment Costs.
Quick Answer: A student loan calculator estimates your monthly payment by dividing your total loan balance by your repayment term and adding interest. For example, a $30,000 loan at 6.5% interest over 10 years costs about **$341 per month** and $10,900 in total interest. Use the calculator above to see your numbers—then explore repayment plans, extra payment strategies, and forgiveness options below.
How to Use the Student Loan Calculator
Using a student loan calculator is simple. Enter these three key details to get an instant estimate:
1. Loan Amount – Enter the total you owe or plan to borrow. If you have multiple loans, add them together.
2. Interest Rate – Use your loan’s annual percentage rate (APR). For federal loans, rates are fixed; for private loans, use your current rate or an average if you have multiple loans.
3. Loan Term – Enter the number of years you have to repay. Common terms are 5, 10, 15, 20, or 25 years.
4. Extra Payments (optional) – Add any extra amount you plan to pay each month to see how much time and interest you can save.
The calculator then shows your estimated monthly payment, total interest cost, and total repayment amount.
Student Loan Payment Examples
Here’s what different loan scenarios look like with current federal interest rates for 2026-27:
| Loan Amount | Interest Rate | Term | Monthly Payment | Total Interest | Total Repayment |
|---|---|---|---|---|---|
| $10,000 | 6.52% | 10 yrs | $114 | $3,660 | $13,660 |
| $20,000 | 6.52% | 10 yrs | $227 | $7,320 | $27,320 |
| $30,000 | 6.52% | 10 yrs | $341 | $10,900 | $40,900 |
| $50,000 | 6.52% | 10 yrs | $568 | $18,200 | $68,200 |
| $30,000 | 6.52% | 20 yrs | $224 | $23,800 | $53,800 |
| $30,000 | 8.07% | 10 yrs | $365 | $13,800 | $43,800 |
Note: 6.52% is the 2026-27 federal undergraduate rate; 8.07% is the graduate rate.
Even a small difference in interest rate or term significantly changes total cost. A $30,000 loan at 6.52% costs $10,900 in interest over 10 years—but at 8.07%, that jumps to $13,800.
Student Loan Payment Formula
Most student loans use an amortisation formula to calculate monthly payments:
M = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1]
Where:
M = Monthly payment
P = Principal loan amount
r = Monthly interest rate (annual rate ÷ 12)
n = Total number of monthly payments (term in years × 12)
For example, a $30,000 loan at 6.52% APR over 10 years:
r = 0.0652 ÷ 12 = 0.005433
n = 10 × 12 = 120
M = 30,000 × [0.005433(1.005433)¹²⁰] ÷ [(1.005433)¹²⁰ − 1] = $341
A student loan calculator does this math instantly, saving you from manual calculations.
Amortization Schedule: How Payments Are Applied
Each monthly payment is split between interest and principal. Early in the loan, most of your payment goes toward interest; over time, more goes toward principal.
Here’s a sample amortisation table for a $5,000 loan at 6% interest over 5 years:
| Date | Principal | Interest | Payment | Balance |
|---|---|---|---|---|
| Jun 2026 | $71.66 | $25.00 | $96.66 | $4,928.34 |
| Jul 2026 | $72.02 | $24.64 | $96.66 | $4,856.31 |
| Aug 2026 | $72.38 | $24.28 | $96.66 | $4,783.93 |

Viewing an amortisation schedule helps you understand exactly how your payments are applied and when you’ll finally own your loan free and clear.
Federal vs. Private Student Loans
Choosing between federal and private loans is one of the most important decisions you’ll make.
Federal Student Loans
Federal loans are issued by the U.S. Department of Education and offer unique protections:
Fixed interest rates – Same rate for every borrower, regardless of credit
No credit check for most undergraduate loans
Income-driven repayment options (though changing in 2026)
Loan forgiveness opportunities like PSLF
Deferment and forbearance protections during financial hardship
Subsidized loans – Government pays interest while you’re in school
2026-27 Federal Interest Rates:
| Loan Type | 2025-26 Rate | 2026-27 Rate |
|---|---|---|
| Undergraduate (Subsidized/Unsubsidized) | 6.39% | 6.52% |
| Graduate/Professional | 7.94% | 8.07% |
| Parent PLUS | 8.94% | 9.07% |
Private Student Loans
Private loans come from banks, credit unions, and online lenders:
Rates vary based on your credit score and income
Fixed or variable interest options
Higher borrowing limits than federal loans
Fewer forgiveness and hardship options
A cosigner is often required
Private loan rates typically range from 2.69% to 17.99% based on creditworthiness.
Comparison Table
| Feature | Federal Loans | Private Loans |
|---|---|---|
| Interest rates | Fixed | Fixed or variable |
| Credit check | Usually not required | Usually required |
| Income-driven repayment | Available (RAP from 2026) | Rare |
| Loan forgiveness | PSLF, Teacher, etc. | Limited |
| Cosigner needed | Rarely | Often |
| Deferment/forbearance | Yes | Limited |
Bottom line: Maximise federal aid before considering private loans.
Student Loan Repayment Plans (2026 Updates)
Major changes to federal repayment plans take effect July 1, 2026, under the One Big Beautiful Bill Act (OBBBA).
For New Borrowers (Loans disbursed on or after July 1, 2026)
New borrowers will have only two repayment plan options:
1. Tiered Standard Repayment Plan – Fixed monthly payments over 10 to 25 years, depending on your total loan amount. If you don’t select a plan, you’ll be automatically enrolled in this one.
2. Repayment Assistance Plan (RAP) – An income-driven plan that bases your monthly payment on your income and family size. Lower income = lower payments. Forgiveness is available after 30 years of qualifying payments.
For Existing Borrowers (Loans disbursed before July 1, 2026)
Current borrowers can remain on their existing plans, but some are being phased out:
| Plan | Status |
|---|---|
| Standard (10-year) | Available |
| Graduated | Available |
| Extended | Available |
| IBR (Income-Based Repayment) | Available |
| PAYE (Pay As You Earn) | Phasing out by July 1, 2028 |
| ICR (Income-Contingent) | Phasing out by July 1, 2028 |
| SAVE | Eliminated – no longer an option |
Borrowers on SAVE, PAYE, or ICR will need to switch to another plan before they’re eliminated.
Public Service Loan Forgiveness (PSLF) in 2026
PSLF forgives remaining federal student loan debt for full-time government and nonprofit workers after 120 qualifying payments (10 years).
Key 2026 updates:
RAP (the new income-driven plan) will qualify for PSLF
The new Tiered Standard Plan will NOT count toward PSLF
Existing IDR plans (IBR, PAYE, ICR) qualify until phased out
After 2028, only IBR and RAP will qualify
Important: Borrowers with loans first disbursed on or after July 1, 2026, will only have the Tiered Standard Plan and RAP as options—meaning they’ll need RAP to pursue PSLF.
Teacher Loan Forgiveness
Teachers working in qualifying low-income schools may qualify for up to $17,500 in loan forgiveness after five consecutive years of full-time teaching. Eligibility depends on the subject taught and the school’s qualification status.
How Extra Payments Save Money
Making extra payments is one of the most powerful ways to reduce your student debt. Extra payments go directly to principal—reducing the balance faster and cutting total interest.
Extra Payment Example
| Scenario | Monthly Payment | Total Interest | Payoff Time |
|---|---|---|---|
| $30,000 @ 6.52%, 10 yrs | $341 | $10,900 | 10 years |
| +$50/month extra | $391 | $9,200 | 9.2 years |
| +$100/month extra | $441 | $7,600 | 8.4 years |
| +$200/month extra | $541 | $4,800 | 7.0 years |
**Savings with $100 extra/month:** $3,300 less interest and 1.6 years sooner.
Extra Payment Strategies
Biweekly payments – Pay half your monthly payment every two weeks (results in one extra payment per year)
Lump-sum contributions – Use tax refunds, bonuses, or gifts
Debt avalanche – Pay extra on the highest-interest loan first
Debt snowball – Pay extra on the smallest balance first for psychological wins
Student Loan Refinancing Calculator
Refinancing replaces your existing loans with a new loan—ideally at a lower interest rate.
When to Refinance
Refinancing makes sense if:
Your credit score has improved significantly
Interest rates have dropped
You have stable income and employment
You want to simplify multiple loans into one payment
2026 Refinance Rates
| Lender | Fixed Rates | Variable Rates |
|---|---|---|
| SoFi | 3.99% – 9.99% APR | 5.74% – 9.99% APR |
| KeyBank | 4.95% – 8.45% (7-yr) | 5.25% – 8.75% (7-yr) |
| Private lenders | ~4% – 14% | Varies |
Warning: Federal Loan Protections
Refinancing federal loans into private loans means losing access to:
Income-driven repayment plans (RAP)
Public Service Loan Forgiveness (PSLF)
Deferment and forbearance options
Loan discharge programs
Only refinance federal loans if you’re certain you won’t need these protections.
FAFSA and Financial Aid
Before borrowing any loans, complete the Free Application for Federal Student Aid (FAFSA). FAFSA determines eligibility for:
Grants – Free money that doesn’t need repayment
Scholarships – Merit-based aid
Work-study – Part-time jobs to earn money for school
Federal loans – Subsidized and unsubsidized options
State aid – Additional funding from your state
Always exhaust grants, scholarships, and work-study before taking out loans.
Tips for Managing Student Debt
Borrow only what you need – Every dollar borrowed costs more with interest
Track all your loans – Use the National Student Loan Data System (NSLDS) for federal loans
Create a budget – Know your income, expenses, and how much you can afford to pay
Understand your grace period – Most federal loans have a 6-month grace period after graduation
Choose the right repayment plan – Use the calculator to compare options
Pay extra when possible – Even small amounts save money over time
Set up autopay – Many lenders offer a 0.25% interest rate discount
Review refinancing annually – Rates change; your credit improves
Keep records – Document all payments and correspondence
Ask for help – Contact your loan servicer if you’re struggling
Frequently Asked Questions
How accurate is a student loan calculator?
Student loan calculators provide estimates based on the information you enter. Actual payments may vary due to fees, interest capitalisation, changes in repayment plans, or variable rates. For the most accurate numbers, use the official Loan Simulator at StudentAid.gov.
Can I pay off my student loans early?
Yes. Most student loans allow penalty-free prepayment. Any extra payment goes directly to principal, reducing total interest.
Does refinancing hurt my credit score?
Applying for refinancing causes a temporary hard inquiry, which may lower your score by a few points. However, on-time payments on the new loan can improve your credit over time.
Should I choose federal or private student loans?
Federal loans first. They offer fixed rates, income-driven repayment, forgiveness programs, and borrower protections that private loans don’t provide. Only consider private loans after exhausting federal options.
How much student debt is too much?
Financial experts recommend borrowing no more than your expected first-year salary after graduation. For example, if you expect to earn $50,000 in your first job, try to keep total borrowing under $50,000.
What is the difference between subsidised and unsubsidised loans?
Subsidised – The government pays interest while you’re in school (at least half-time) and during grace/deferment periods. Need-based.
Unsubsidised – Interest accrues from the moment the loan is disbursed.
What happens if I can’t make my student loan payments?
Contact your loan servicer immediately. Options include:
Deferment – Temporarily postpone payments (interest may still accrue)
Forbearance – Temporarily reduce or pause payments
Income-driven repayment – Lower payments based on income
Loan consolidation – Combine loans for simpler management
Will student loans be forgiven in 2026?
Broad forgiveness is not currently available for all borrowers. However, specific programs exist:
PSLF – After 120 payments working in public service
Teacher Loan Forgiveness – After 5 years in qualifying schools
IDR forgiveness – After 20-30 years of income-driven payments
What are the new student loan rules for 2026?
Major changes effective July 1, 2026:
New borrowers get only two plans: Tiered Standard and RAP
SAVE, PAYE, and ICR are being phased out
Grad PLUS loans eliminated for new borrowers
Parent PLUS borrowing limits reduced
Colleges can limit loans based on major of study
