1. What is the EMI Formula?

The EMI (Equated Monthly Installment) formula calculates the fixed payment amount a borrower makes to a lender at a specified date each calendar month. It's commonly used for mortgage loans in New Zealand, including Kiwibank mortgages.

2. How Does the Calculator Work?

The calculator uses the EMI formula:

Where:

• \( P \) — Principal loan amount (NZD)
• \( R \) — Monthly interest rate (annual rate divided by 12, in decimal)
• \( N \) — Loan tenure in months

Explanation: The formula accounts for both principal repayment and interest payment components that change over the loan term.

3. Importance of EMI Calculation

Details: Calculating EMI helps borrowers understand their monthly financial commitment, compare loan offers, and plan their budget accordingly.

4. Using the Calculator

Tips: Enter the principal amount in NZD, annual interest rate as a percentage, and loan term in years. All values must be positive numbers.
