What Is a Loan and How Repayment Works

A loan is a borrowed amount that must be repaid over time with interest. Most loans follow a fixed repayment schedule where the borrower pays a set amount every month until the loan is fully repaid.

Each payment generally includes:

  • Principal repayment
  • Interest charged on the remaining balance

This calculator assumes standard fixed-rate loan repayment, which is common for most consumer and business loans.

How Payments Are Calculated

Loan payments are calculated using an amortization formula that spreads repayment evenly over the loan term. While the monthly payment stays the same, the interest portion is higher at the beginning and decreases over time.

Types of Loans You Can Calculate

Personal Loans

Travel, emergencies, or consolidation.

Student Loans

Education loans with fixed periods.

Business Loans

Expansion, equipment, or capital.

General Loans

Any fixed-term installment loan.

Interest Rate & Tenure Impact

Interest Rate

Higher interest rates increase both monthly payments and total interest paid.

Loan Term

Longer terms reduce monthly payments but increase overall interest. Shorter terms cost less overall but have higher monthly payments.

Common Planning Mistakes

  • Borrowing based only on monthly affordability
  • Ignoring total interest cost
  • Choosing longer tenure without understanding impact
  • Not comparing multiple scenarios
