Student Loan Calculator | Calculate Your Education Repayments

Managing student loans can be stressful, especially when trying to plan repayments and budget your finances. A Student Loan Calculator helps you quickly determine your monthly payments, total interest, and the overall cost of your loan based on your loan amount, interest rate, and repayment period. Understanding these numbers helps you make smarter financial decisions and reduce stress.

Why a Student Loan Calculator is Important

  • Financial Planning: Know how much you need to pay each month.
  • Interest Awareness: Understand how interest affects total repayment.
  • Budgeting: Helps plan your expenses around loan repayments.
  • Education Choices: Compare different loan options and repayment plans.

Loan Repayment Formulas

The standard formula for calculating monthly student loan payments is based on an amortization formula:

P = (L × r × (1+r)n) / ((1+r)n − 1)

  • P – Monthly payment
  • L – Loan principal amount
  • r – Monthly interest rate (annual rate ÷ 12)
  • n – Total number of monthly payments (years × 12)

Step-by-Step Example 1: Monthly Payment

Problem: You borrowed $30,000 with an annual interest rate of 5% for 10 years. Calculate your monthly payment.
Step 1: Convert annual interest to monthly: r = 5% ÷ 12 = 0.0041667
Step 2: Total payments: n = 10 × 12 = 120
Step 3: Apply formula:
P = (30,000 × 0.0041667 × (1+0.0041667)120) / ((1+0.0041667)120 − 1)
P ≈ $318.20 per month

Step-by-Step Example 2: Total Interest Paid

Step 1: Total repayment = Monthly payment × Number of months
Total repayment = 318.20 × 120 ≈ 38,184
Step 2: Total interest = Total repayment − Principal
Total interest = 38,184 − 30,000 = $8,184
