What is a Student Loan Calculator?
A Student Loan Calculator is a financial tool that estimates the cost of repaying a loan taken out for education. By entering details such as loan amount, interest rate, and repayment term, it calculates:
- Monthly payment
- Total interest paid
- Total repayment amount
- Potential savings with early payoff
This tool is beneficial for both students and graduates who want to create a repayment strategy that fits within their financial limits.
How to Use the Student Loan Calculator
Using the Student Loan Calculator is simple and requires just a few inputs:
- Enter the Loan Amount – This is the principal amount you have borrowed or plan to borrow.
- Enter the Annual Interest Rate (%) – The percentage charged by the lender annually on the outstanding balance.
- Enter the Loan Term (Years) – The number of years you plan to take to repay the loan.
- Click “Calculate” – The tool will display your monthly payment, total interest, and total repayment amount.
- Adjust Values for Comparison – You can try different terms or interest rates to see how they affect your payments.
Formula Used in the Student Loan Calculator
The calculator uses the loan amortization formula to determine monthly payments:
Monthly Payment (M) = P × [ r(1 + r)ⁿ ] / [ (1 + r)ⁿ – 1 ]
Where:
- P = Loan amount (principal)
- r = Monthly interest rate (annual interest rate ÷ 12)
- n = Total number of monthly payments (loan term × 12)
Total Interest Paid = (Monthly Payment × Total Months) – Principal Amount
Example Calculation
Example 1:
- Loan Amount: $30,000
- Interest Rate: 5% annual
- Term: 10 years
Step 1: Convert annual interest rate to monthly rate:
5% ÷ 12 = 0.004167
Step 2: Calculate total number of payments:
10 × 12 = 120 months
Step 3: Apply the formula:
M = 30000 × [ 0.004167(1 + 0.004167)¹²⁰ ] / [ (1 + 0.004167)¹²⁰ – 1 ]
M ≈ $318.20
Results:
- Monthly Payment: $318.20
- Total Interest: $8,184
- Total Repayment: $38,184
