  • The calculator converts it into months for accurate payments.

Step 4: Select Start Date

  • Choose when your loan repayment will begin.
  • The schedule adjusts accordingly.

    • Monthly Payment
    • Total Interest Paid
    • Total Repayment Amount

Step 6: Review the Amortization Schedule

  • The tool generates a month-by-month breakdown:
    • Payment number
    • Date
    • Total payment
    • Principal paid
    • Interest paid

Practical Example

Imagine you’re taking a $10,000 personal loan at an annual interest rate of 5% for 3 years.

  • Loan Amount: $10,000
  • Interest Rate: 5%
  • Loan Term: 3 years (36 months)
  • Start Date: Today

After calculation, the results would be:

  • Monthly Payment: $299.71
  • Total Interest Paid: $789.56
  • Total Amount Paid: $10,789.56

The amortization schedule will show all 36 payments, with the interest portion getting smaller and the principal portion getting larger over time.
