Mortgage Cash Out Refinance Formula Explained
This calculator uses a standard amortization formula to estimate monthly payments.
1. New Loan Amount Calculation
The new loan amount is:
New Loan = Current Balance + Cash-Out Amount
This is the total amount you will repay after refinancing.
2. Monthly Mortgage Payment Formula
The monthly payment is calculated using:
M=1−(1+r)−nP⋅r
Where:
- M = Monthly payment
- P = Loan amount
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (years × 12)
3. Total Interest Calculation
Total interest is calculated as:
Total Interest = (Monthly Payment × Number of Payments) − Loan Amount
This shows the long-term cost of borrowing.
Example Calculation
Let’s understand with a real-life example.
Scenario:
- Home Value: $300,000
- Current Loan Balance: $180,000
- Cash-Out: $40,000
- Interest Rate: 6%
- Loan Term: 30 years
Step 1: New Loan Amount
180,000 + 40,000 = $220,000
Step 2: Monthly Payment
Using the formula, the estimated monthly payment is:
👉 $1,318.58 per month (approx.)
Step 3: Total Interest
Over 30 years, total interest paid will be:
👉 Approximately $253,000+
Step 4: Cash Received
