What is a Mortgage Loan?
A Mortgage Loan Mortgage Loan is a type of secured loan used to purchase or maintain a home, land, or other real estate. The borrower agrees to repay the lender over a fixed period, usually with interest added.
The repayment is typically divided into monthly installments, known as EMIs (Equated Monthly Installments). These payments include both:
- Principal (original loan amount)
- Interest (cost of borrowing money)
Understanding how these payments are calculated helps borrowers avoid financial stress and plan long-term budgets more effectively.

How Mortgage Calculations Work
Mortgage payments are calculated using a fixed mathematical formula that ensures equal monthly installments throughout the loan term.
The calculator converts annual interest into monthly interest and then applies compounding over time.
This ensures that every monthly payment includes:
- Interest portion (based on remaining balance)
- Principal repayment portion
As time progresses, the interest portion decreases while the principal portion increases.
Mortgage Payment Formula Explained
The standard formula used is:
Monthly Payment Formula:
M = P × r × (1 + r)^n / [(1 + r)^n − 1]
Where:
- M = Monthly payment
- P = Loan principal amount
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of months (years × 12)
Total Payment Formula:
Total Payment = Monthly Payment × Number of Months
Total Interest Formula:
Total Interest = Total Payment − Principal Loan Amount
This formula ensures accurate financial forecasting, helping borrowers understand long-term costs before committing.
Example Calculation
Let’s understand with a real-life example:
Loan Details:
- Loan Amount: $150,000
- Interest Rate: 5% per year
- Loan Term: 20 years
Step-by-step breakdown:
- Monthly interest rate = 5 ÷ 12 ÷ 100 = 0.004167
- Loan duration = 20 × 12 = 240 months
After applying the formula:
Results:
- Monthly Payment: ≈ $989
- Total Payment: ≈ $237,360
- Total Interest: ≈ $87,360
This example shows how interest significantly increases total repayment over time.
