Understanding the Mortgage Formula
This calculator uses the standard amortization formula used by banks and financial institutions.
Monthly Mortgage Payment Formula:
M=(1+r)n−1P⋅r⋅(1+r)n
Where:
- M = Monthly mortgage payment
- P = Loan principal (loan amount)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (loan term in months)
Step-by-Step Explanation:
- Convert annual interest rate into monthly rate
- Multiply loan amount with monthly interest rate
- Apply compound interest over loan duration
- Divide by amortization factor
This formula ensures that each monthly payment includes both principal and interest.
Example Mortgage Calculation
Let’s understand how the calculator works with a real-life example.
Example Scenario:
- Loan Amount: $350,000
- Interest Rate: 6% per year
- Loan Term: 30 years
Step 1: Convert Values
- Monthly interest rate = 6% ÷ 12 = 0.5% (0.005)
- Loan duration = 30 × 12 = 360 months
Step 2: Apply Formula
Using the mortgage formula, the result will be:
- Monthly Payment ≈ $2,098.43
- Total Payment ≈ $755,434.80
- Total Interest ≈ $405,434.80
What Affects Your Mortgage Payments?
Several factors influence how much you pay every month:
1. Loan Amount
Higher loan amounts lead to higher monthly payments.
2. Interest Rate
Even a 1% difference can significantly increase total interest over time.
3. Loan Term
Longer terms reduce monthly payments but increase total interest.
4. Credit Score
A better credit score usually means lower interest rates.
5. Down Payment
A larger down payment reduces your loan size and monthly burden.
