What is a Mortgage Calculator?

A mortgage calculator is a tool that calculates the monthly repayment amount for a home loan based on:

  • Principal Loan Amount – The amount borrowed to buy the house
  • Interest Rate – Annual rate charged by the lender
  • Loan Tenure – Duration of the mortgage, usually in years

Mortgage calculators are essential for:

  • Estimating monthly payments
  • Planning financial budgets
  • Comparing loan offers
  • Understanding total interest costs

Formula for Calculating Mortgage Payments

The standard formula for calculating monthly mortgage payments (EMI) is:

EMI = [P × R × (1 + R)^N] ÷ [(1 + R)^N − 1]

Where:

  • P = Principal loan amount
  • R = Monthly interest rate (annual rate ÷ 12 ÷ 100)
  • N = Total number of monthly payments (tenure × 12)

Total Interest = (EMI × N) − P

This formula ensures precise monthly payment calculations including both principal and interest components.

Example Calculation

Scenario:

  • Principal: $250,000
  • Interest Rate: 6% per annum
  • Loan Tenure: 30 years (360 months)

Step 1: Convert Annual Rate to Monthly
R = 6 ÷ 12 ÷ 100 = 0.005

Step 2: Calculate EMI
EMI = [250,000 × 0.005 × (1 + 0.005)^360] ÷ [(1 + 0.005)^360 − 1]
EMI ≈ $1,498.88

Step 3: Calculate Total Interest
Total Interest = (1,498.88 × 360) − 250,000 ≈ $289,596.80

Result: Monthly payments are $1,498.88, and total interest over 30 years is $289,596.80.
