Managing student loans can be overwhelming — especially when trying to figure out how much you’ll pay each month and how long it will take to be debt-free. That’s where our Student Loan Amortization Calculator comes in.
This online tool helps you calculate your monthly payments, total interest, and amortization schedule based on your loan amount, interest rate, and repayment term.
Whether you’re a student planning your finances or a graduate managing repayments, this calculator provides clarity, helping you make informed decisions about your financial future.
🎯 Purpose of the Student Loan Amortization Calculator
The calculator’s main goal is to help borrowers understand how their student loan is paid off over time — showing the breakdown of principal and interest in each payment.
It answers questions like:
- How much will I pay each month?
- How much interest will I pay overall?
- When will my loan be fully paid off?
By using amortization formulas, the tool reveals the complete payment structure — allowing you to plan better, refinance smartly, or accelerate your repayment strategy.
⚙️ How to Use the Calculator
Using the Student Loan Amortization Calculator is simple and takes only a few seconds:
- Enter Loan Amount 💰

Provide your loan’s annual interest rate (e.g., 5.5%). - Enter Loan Term 📅
Specify the number of years you plan to take to pay off the loan. - Select Payment Frequency (Monthly, Biweekly, etc.)
Most student loans use monthly payments. - Click “Calculate”
The tool instantly shows:- Monthly payment
- Total interest paid
- Total repayment amount
- Detailed amortization schedule (month-by-month breakdown)
🧮 Formula Used in the Calculator
The calculator uses the standard amortization formula: M=P×r(1+r)n(1+r)n−1M = P \times \frac{r(1 + r)^n}{(1 + r)^n – 1}M=P×(1+r)n−1r(1+r)n
Where:
- MMM = Monthly payment
- PPP = Principal (loan amount)
- rrr = Monthly interest rate (annual rate ÷ 12)
- nnn = Total number of payments (years × 12)
This formula ensures accurate calculations and a realistic payoff projection.
💡 Example Calculation
Let’s take an example:
- Loan Amount: $35,000
- Interest Rate: 5%
- Loan Term: 10 years
Step 1:
Convert interest rate: 5% ÷ 12 = 0.004167
Step 2:
Number of payments: 10 × 12 = 120
Step 3:
Plug into formula: M=35000×0.004167(1+0.004167)120(1+0.004167)120−1M = 35000 \times \frac{0.004167(1 + 0.004167)^{120}}{(1 + 0.004167)^{120} – 1}M=35000×(1+0.004167)120−10.004167(1+0.004167)120
Result:
✅ Monthly payment = $371.23
✅ Total interest = $9,547.60
✅ Total repayment = $44,547.60
📊 Amortization Schedule Overview
An amortization schedule displays the month-by-month breakdown of your payments:
| Month | Payment | Principal | Interest | Balance |
|---|---|---|---|---|
| 1 | $371.23 | $225.23 | $146.00 | $34,774.77 |
| 12 | $371.23 | $238.50 | $132.73 | $32,040.00 |
| 60 | $371.23 | $302.10 | $69.13 | $18,292.00 |
| 120 | $371.23 | $370.12 | $1.11 | $0.00 |
👉 Over time, your interest portion decreases while your principal portion increases — meaning more of your money goes toward paying off the loan.

By visualizing your loan’s life cycle, you gain control over your financial strategy.
