How to Use Loan Calculator 💡

See how monthly payments change based on repayment methods.

1. Enter Loan Amount, Interest Rate, and Term.

2. Select Repayment Method.

Repayment Types

  • Equal P & I: Monthly payment (Principal + Interest) stays the same. Good for budgeting.
  • Equal Principal: Principal payment is constant, interest decreases. Higher initial payments but lower total interest.
  • Bullet: Pay only interest monthly, and principal at the end. Low monthly burden but requires a large sum at maturity.
