Mortgage Calculation Formula Explained
The calculator uses the standard fixed-rate mortgage formula, which is widely used in financial institutions.
Monthly Mortgage Payment Formula:
M=(1+r)n−1Pr(1+r)n
Where:
- M = Monthly mortgage payment
- P = Loan principal (loan amount)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (years × 12)
Step-by-Step Breakdown
- Convert annual interest rate into monthly rate
- Multiply loan term in years by 12 to get total months
- Apply the formula to calculate monthly installment
- Multiply monthly payment by total months for total repayment
- Subtract principal to find total interest paid
This ensures accurate long-term loan estimation.
Example Calculation
Let’s understand this with a real-life example:
Loan Details:
- Loan Amount: $300,000
- Interest Rate: 5% per year
- Loan Term: 25 years
Step 1: Convert values
- Monthly interest rate = 5 ÷ 12 ÷ 100 = 0.004167
- Total months = 25 × 12 = 300
Step 2: Monthly Payment
Using the formula:
Monthly payment ≈ $1,754.39
Step 3: Total Payment
$1,754.39 × 300 = $526,317
Step 4: Total Interest
$526,317 − $300,000 = $226,317
Final Result Summary:
- Monthly Payment: $1,754.39
- Total Payment: $526,317
- Total Interest: $226,317
This shows how much extra cost you pay over time due to interest.
