Understanding the Mortgage Formula
The calculator uses the standard amortization formula used by banks worldwide.
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)
What This Formula Means
This formula ensures your loan is repaid in equal monthly installments over 15 years. Each payment includes:
- Interest portion (bank’s profit)
- Principal portion (loan repayment)
At the start, interest is higher, and over time, principal repayment increases.
Example Calculation
Let’s understand this with a real-life example:
Loan Details:
- Loan Amount = $200,000
- Interest Rate = 6% per year
- Loan Term = 15 years
Step 1: Convert values
- Monthly interest rate = 6 ÷ 12 ÷ 100 = 0.005
- Total months = 15 × 12 = 180
Step 2: Apply formula
Monthly payment ≈ $1,687.71
Step 3: Calculate totals
- Total payment = $303,787.80
- Total interest = $103,787.80
Final Result:
A $200,000 loan at 6% interest for 15 years will cost:
- 💰 Monthly Payment: ~$1,687
- 💰 Total Interest: ~$103,787
