What is a Mortgage Calculator?
A mortgage calculator is a financial tool that estimates your monthly loan repayment based on:
- Loan amount (principal)
- Interest rate
- Loan duration (years)
It breaks down your repayment into:

- Total interest paid
This helps borrowers understand affordability before taking a mortgage.

Mortgage Payment Formula Explained
The calculator uses a standard amortization formula used by banks worldwide:
Monthly Mortgage Payment Formula:
M=(1+r)n−1P×r×(1+r)n
Where:
- M = Monthly payment
- P = Loan principal (loan amount)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of months (years × 12)
Understanding the Formula in Simple Words
- The loan is divided into equal monthly payments.
- Interest is applied every month on the remaining balance.
- Early payments mostly cover interest, while later payments reduce principal.
This is called an amortized loan system.
Example Calculation
Let’s assume:
- Loan Amount = $150,000
- Interest Rate = 6% per year
- Loan Term = 25 years
Step 1: Convert values
- Monthly interest = 6% ÷ 12 = 0.5% = 0.005
- Months = 25 × 12 = 300
Step 2: Monthly Payment Result
- Monthly Payment ≈ $966.64
- Total Payment ≈ $289,992
- Total Interest ≈ $139,992
Insight:
You will pay almost double the borrowed amount over 25 years due to interest.

Understanding Mortgage Costs
When you take a mortgage, you don’t just pay back the loan amount. You also pay:
1. Principal
The original loan amount.
2. Interest
The cost of borrowing money.
3. Total Payment
Principal + Interest over the full loan term.
Impact of Interest Rate on Your Loan
Even a small change in interest rate can significantly affect your total payment.
| Interest Rate | Monthly Payment | Total Interest |
|---|---|---|
| 4% | Lower | Lower |
| 6% | Medium | Medium |
| 8% | Higher | Much Higher |
Key Insight:
A 1% increase in interest can cost thousands over time.
Loan Term Impact
Longer loan terms reduce monthly payments but increase total interest.
Short Term (10–15 years)
- Higher monthly payments
- Less total interest
Long Term (25–30 years)
- Lower monthly payments
- Higher total interest
