Mortgage Calculation Formula Explained
The calculator uses the standard loan amortization formula used by banks worldwide.
1. Loan Amount
Loan Amount = Home Price − Down Payment
This is the actual amount you borrow from the bank.
2. Monthly Interest Rate
Monthly Rate = Annual Interest Rate ÷ 12 ÷ 100
This converts yearly interest into monthly interest.
3. Monthly Mortgage Payment (EMI)
Monthly Payment Formula:EMI=(1+r)n−1P×r×(1+r)n
Where:
- P = Loan Amount
- r = Monthly Interest Rate
- n = Total Number of Months (20 × 12 = 240)
4. Total Payment
Total Payment = Monthly Payment × Number of Months
5. Total Interest
Total Interest = Total Payment − Loan Amount
Example Calculation
Let’s understand with a real-life example:
Scenario:
- Home Price = $300,000
- Down Payment = $60,000
- Interest Rate = 6%
- Loan Term = 20 Years
Step-by-Step Result:

|---|---|
| Loan Amount | $240,000 |
| Monthly Payment | $1,719.35 |
| Total Payment | $412,644 |
| Total Interest | $172,644 |
Explanation:
- You borrow $240,000 after down payment
- You pay around $1,719 every month
- Over 20 years, total payment becomes $412,644
- Interest paid is $172,644
Mortgage Comparison Table
Here’s how interest rate affects your monthly payments:
| Loan Amount | Interest Rate | Monthly Payment | Total Interest |

| $200,000 | 4% | $1,212 | $91,072 |
| $200,000 | 6% | $1,432 | $143,739 |

How Mortgage Interest Affects Your Loan
Even a small change in interest rate can significantly impact your total payment.
Example:
- At 5% interest → lower EMI and savings on interest
- At 7% interest → higher EMI and much more total interest
This is why comparing mortgage rates is very important before choosing a lender.
