Mortgage Calculation Formula Explained
This calculator uses the standard fixed-rate mortgage formula:
Monthly Payment Formula:
M=(1+r)n−1P×r×(1+r)n
Where:
- M = Monthly payment
- P = Loan principal (home loan amount)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (loan term in months)
How It Works
- Annual interest rate is converted into a monthly rate
- Loan term is converted into months
- The formula calculates fixed monthly payments
- Total payment = monthly payment × number of months
- Total interest = total payment − loan amount
This method ensures accurate mortgage estimation based on real-world lending systems.
Example Calculation
Let’s understand with a real example:
Loan Details:
- Loan Amount: $300,000
- Interest Rate: 6% per year
- Loan Term: 30 years
Step 1: Convert Values
- Monthly interest rate = 6 ÷ 12 ÷ 100 = 0.005
- Loan term = 30 × 12 = 360 months
Step 2: Apply Formula
Monthly Payment ≈ $1,799.00
Step 3: Final Results
- Monthly Payment: $1,799.00
- Total Payment: $647,640.00
- Total Interest: $347,640.00
This example shows how interest significantly increases the total cost of a home loan over time.
