🎓 Student loans can feel overwhelming, especially when you realize that interest doesn’t just appear once a month- it accrues every single day.
Understanding daily interest is the key to managing repayment effectively, cutting down long-term costs, and making smarter payment decisions.
That’s why I have created a Daily Interest Calculator for Student Loans to show you exactly how much interest builds up daily and how different payment strategies affect your balance.

🎓 Simple Daily Interest Calculator (Student Loans)
See your daily interest and a quick projection. Uses simple daily interest: daily rate = APR ÷ days-in-year.
Projection assumes simple daily interest and no capitalization or payments during the period.
🕑 How Daily Interest on Student Loans Works
Most student loans use simple daily interest, meaning interest accrues daily on your outstanding principal balance. Here’s how it works:
- Step 1: Convert the APR to a daily rate
Daily Rate = APR ÷ 365
Example: A 6% loan → 0.06 ÷ 365 = 0.000164 - Step 2: Multiply by your current balance
Daily Interest = Balance × Daily Rate
Example: $20,000 balance × 0.000164 ≈ $3.28 per day - Step 3: Add up for the month
Over 30 days, that’s ≈ $98.40 in interest.
Unlike some credit cards or personal loans, student loans usually don’t compound daily. However, unpaid interest may capitalize (get added to your principal) during deferment, forbearance, or at certain repayment milestones.
📊 Examples of Daily Interest Accrual
- $10,000 loan at 5% APR → Daily interest ≈ $1.37 → ≈ $41/month
- $20,000 loan at 6% APR → Daily interest ≈ $3.28 → ≈ $98/month
- $35,000 loan at 7% APR → Daily interest ≈ $6.71 → ≈ $201/month
Even small APR differences make a big impact over years of repayment.
