A mortgage cash-out refinance calculator is an essential financial tool for homeowners looking to tap into their home equity while refinancing their mortgage. Unlike traditional refinancing, where you simply change the terms of your mortgage (like interest rate or loan duration), a cash-out refinance allows you to replace your existing loan with a new, larger one — and take the difference in cash.
Mortgage Cash Out Refinance Calculator
How to Use the Mortgage Cash Out Refinance Calculator
Using this tool is straightforward. Here’s how:
- Enter Current Home Value: Input the current market value of your property.
- Enter Remaining Mortgage Balance: Fill in how much you still owe on your existing mortgage.
- Select Loan-to-Value (LTV) Ratio Limit: Most lenders allow an LTV up to 80%, meaning you can borrow up to 80% of your home’s current value.
- Calculate: The tool will display the maximum amount you can cash out, your new mortgage amount, and the equity remaining.
This calculator instantly provides a clear breakdown of your refinancing capacity, including the available equity you can convert into cash.
Formula Used in the Calculator
The core formula behind the Mortgage Cash Out Refinance Calculator is:
Maximum Loan Amount = Home Value × Maximum LTV Ratio
Cash Out Amount = Maximum Loan Amount − Existing Mortgage Balance
Example:
- Home Value: $400,000
- Maximum LTV: 80%
- Mortgage Balance: $240,000
Step 1: Calculate Maximum Loan Amount
= $400,000 × 0.80 = $320,000
Step 2: Calculate Cash Out Amount
= $320,000 − $240,000 = $80,000
In this case, you may be eligible to cash out up to $80,000 while refinancing.
Real-Life Example
Let’s say you’ve owned your house for 10 years. It has appreciated in value from $250,000 to $400,000, and your remaining mortgage is $200,000. You’re planning a home renovation project and want to use a cash-out refinance to fund it.
Input:
- Current home value: $400,000
- Current mortgage balance: $200,000
- LTV ratio allowed: 80%
Calculation:
- Max new mortgage: $400,000 × 0.80 = $320,000
- Cash out possible: $320,000 − $200,000 = $120,000
You could access $120,000 in cash, refinance your mortgage, and potentially even secure a lower interest rate — making this a financially strategic move.
Benefits of Using This Calculator
- Saves Time: Quickly see what you’re eligible for without contacting lenders first.
- Better Planning: Helps you budget renovations or other expenditures.
- Avoid Over-Borrowing: Understand limitations and avoid taking on too much debt.
- Loan Comparison: Simulate different scenarios by adjusting values to find the optimal refinancing plan.

When Should You Use a Cash-Out Refinance?
- Home Renovations: Upgrade or expand your property to increase value.
- Debt Consolidation: Pay off high-interest credit cards or personal loans.
- Education Expenses: Fund college or trade school tuition.
- Investment: Use cash to invest in another property or business.
However, refinancing resets your loan term and can increase the total interest paid, so evaluate long-term costs carefully.
Things to Consider
- Closing Costs: Cash-out refinancing typically comes with closing costs, often 2–5% of the loan.
- Credit Score Requirements: Lenders may require higher credit scores for cash-out refinancing.
- Risk of Foreclosure: You’re increasing your loan balance; failure to repay can result in loss of your home.
- Long-Term Interest: The interest accrued over a longer-term may outweigh short-term benefits.
- Lender Rules: Not all lenders offer the same LTV limit; some may cap it at 75% for cash-out purposes.
