Mortgage Calculation Formula Explained
The calculator uses a standard amortization formula used by banks and financial institutions worldwide.
Monthly Mortgage Payment Formula:
M=1−(1+r)−nP⋅r
Where:
- M = Monthly mortgage payment
- P = Loan principal (750,000 USD)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (years × 12)
Understanding the Formula in Simple Terms
This formula may look complex, but it simply calculates how much you need to pay every month to fully repay your loan within a fixed time period.
- Higher interest rate → Higher monthly payment
- Longer loan term → Lower monthly payment but more total interest
- Larger loan amount → Higher payments overall
Example Calculation
Let’s understand how this calculator works with a real-life example.
Loan Details:
- Loan Amount: $750,000
- Interest Rate: 6% per year
- Loan Term: 30 years
Step 1: Monthly Interest Rate
6% ÷ 12 = 0.5% per month
Step 2: Total Payments
30 × 12 = 360 months
Step 3: Result
- Monthly Payment ≈ $4,498.21
- Total Payment ≈ $1,619,355.60
- Total Interest ≈ $869,355.60
This shows how much extra you pay over the original loan due to interest.
