A mortgage loan is a secured loan used to purchase real estate, where the property itself serves as collateral. The borrower agrees to pay back the loan amount plus interest over a specified period, typically 15-30 years.

Mortgage Loan Calculation Formula
EMI Calculation Formula
The standard formula for calculating EMI is:
EMI = P × r × (1 + r)^n / [(1 + r)^n - 1]
Where:
- P = Principal loan amount
- r = Monthly interest rate (annual rate ÷ 12)
- n = Total number of months
Example Calculation
Given:
- Loan Amount: $300,000
- Annual Interest Rate: 4.5%
- Loan Term: 30 years (360 months)
Calculation:
- Monthly Rate (r) = 4.5% ÷ 12 = 0.375% = 0.00375
- Number of Months (n) = 30 × 12 = 360
EMI = 300,000 × 0.00375 × (1 + 0.00375)^360 / [(1 + 0.00375)^360 - 1]
EMI = 300,000 × 0.00375 × 3.8477 / 2.8477
EMI = 300,000 × 0.00375 × 1.3512
EMI = $1,520.06
Mortgage Loan Components Breakdown
1. Principal and Interest
Principal:
- The actual loan amount borrowed
- Reduces over time as you make payments
- Tax-deductible (interest portion)
Interest:
- Cost of borrowing money
- Higher in early years (amortization)
- Tax-deductible for primary residences
2. Property Taxes
Annual Property Tax:
- Based on property value
- Varies by location
- Usually escrowed with mortgage payment
Monthly Tax Payment:
Monthly Tax = Annual Property Tax ÷ 12
3. Homeowners Insurance
Coverage Types:
- Property damage
- Liability protection
- Personal property coverage
Monthly Premium:
Monthly Insurance = Annual Premium ÷ 12
4. Private Mortgage Insurance (PMI)
When Required:
- Down payment less than 20%
- Conventional loans only
- Can be removed after 20% equity
Cost:
- 0.5% to 1.5% of loan amount annually
- Added to monthly payment
Total Monthly Payment Calculation
PITI Formula
PITI = Principal + Interest + Taxes + Insurance
Example:
- Principal & Interest: $1,520
- Property Tax: $3,600/year = $300/month
- Insurance: $1,200/year = $100/month
- PMI: $1,800/year = $150/month
Total Monthly Payment:
$1,520 + $300 + $100 + $150 = $2,070
