Mortgage Payment Formula Explained
The calculator uses a standard mortgage amortization formula used by banks worldwide.
Monthly Payment Formula:
M=1−(1+r)−nP×r
Where:
- M = Monthly payment
- P = Loan amount (principal)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (loan term in months)
How the Calculation Works
Step 1: Convert Annual Interest Rate
The annual interest rate is divided by 12 to get the monthly rate.
Step 2: Convert Loan Term to Months
Loan duration in years is multiplied by 12.
Step 3: Apply Mortgage Formula
The formula calculates a fixed monthly payment that includes both principal and interest.
Step 4: Calculate Total Cost
- Total Payment = Monthly Payment × Number of Months
- Total Interest = Total Payment − Loan Amount
Example Calculation
Let’s understand with a real-world example:
Loan Details:
- Loan Amount: $250,000
- Interest Rate: 5% per year
- Loan Term: 30 years
Step 1: Monthly Interest Rate
5% ÷ 12 = 0.004167
Step 2: Total Months
30 × 12 = 360 months
Step 3: Monthly Payment Result
Monthly payment ≈ $1,342.05
Step 4: Total Payment
$1,342.05 × 360 = $483,138
Step 5: Total Interest
$483,138 − $250,000 = $233,138
