Mortgage Calculation Formula Explained
The calculator uses a standard amortization formula to compute monthly payments:
Monthly Mortgage Payment Formula:
M=(1+r)n−1P⋅r⋅(1+r)n
Where:
- M = Monthly payment
- P = Loan amount (principal)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (years × 12)
Total Payment Formula:
Total Payment=M×n
Total Interest Formula:
Total Interest=(M×n)−P
Step-by-Step Example Calculation
Let’s understand with a real-life example:
- Loan Amount = $200,000
- Interest Rate = 6% per year
- Loan Term = 30 years
Step 1: Convert values
- Monthly interest rate = 6 ÷ 12 ÷ 100 = 0.005
- Total months = 30 × 12 = 360
Step 2: Apply formula
Monthly payment comes out approximately:
👉 $1,199.10 per month
Step 3: Total payment
1199.10×360=431,676
Step 4: Total interest
431,676−200,000=231,676
Final Results:
- Monthly Payment: $1,199.10
- Total Payment: $431,676
- Total Interest: $231,676
This shows how much extra you pay over time due to interest.
