Cash Out Mortgage Calculator

Homeowners often build equity over time as their property value increases and their mortgage balance decreases. That equity can potentially be accessed through a cash out refinance, allowing you to replace your existing mortgage with a larger loan and receive part of the difference in cash.

However, refinancing involves more than simply calculating how much money you can borrow. You also need to consider your home’s current value, remaining mortgage balance, desired cash out amount, interest rate, loan term, and closing costs. These factors affect both the cash you receive and the long-term cost of the new loan.

Our Cash Out Mortgage Calculator helps you estimate these figures in one place. By entering a few details, you can review your potential new loan amount, cash available after closing costs, loan-to-value ratio, estimated monthly payment, total interest, and total repayment.

This tool is designed for homeowners who want a quick starting point before comparing refinance offers or discussing their options with a mortgage professional.

What Is a Cash Out Mortgage Calculator?

A Cash Out Mortgage Calculator is a financial planning tool that estimates the results of borrowing additional money against your home’s equity through a cash out refinance.

The calculator combines your current mortgage balance with the amount of cash you want to withdraw. It then uses the new interest rate and loan term to estimate the monthly principal-and-interest payment.

The tool also subtracts closing costs from the requested cash amount to show an estimated amount of cash available after costs.

For example, if your current mortgage balance is $200,000 and you want to take out $30,000, the estimated new loan amount would be:

$200,000 + $30,000 = $230,000

If closing costs are $5,000, the estimated cash available after costs would be:

$30,000 − $5,000 = $25,000

These calculations help you understand the relationship between the money you receive today and the loan you will repay over time.

What Does the Cash Out Mortgage Calculator Calculate?

After you enter your information, the calculator provides several useful results.

ResultWhat It Means
New Loan AmountYour existing mortgage balance plus the requested cash out amount
Cash Available After CostsThe requested cash out amount minus estimated closing costs
Loan-to-Value RatioThe new loan amount expressed as a percentage of your home’s value
Estimated Monthly PaymentThe estimated monthly principal-and-interest payment on the new loan
Total Interest Over Loan TermThe estimated interest paid over the full repayment period
Total RepaymentThe estimated principal and interest paid over the entire loan term

These results can help you evaluate whether a proposed refinance fits your financial plans.

How to Use the Cash Out Mortgage Calculator

Using the calculator is simple. Follow these steps to estimate your potential cash out refinance.

Step 1: Enter Your Current Home Value

In the Current Home Value field, enter your property’s estimated market value.

For example:

$350,000

Use a realistic estimate based on recent comparable sales, a professional appraisal, or another reliable valuation source. The home’s value is important because it affects the maximum loan amount allowed by the calculator.

Step 2: Enter Your Current Mortgage Balance

Enter the amount you still owe on your existing mortgage.

For example:

$200,000

This should be your remaining loan balance, not the original amount you borrowed.

Step 3: Enter Your Desired Cash Out Amount

Enter how much money you want to receive from the refinance.

For example:

$30,000

Think about the purpose of the cash before choosing an amount. You may be considering home improvements, debt consolidation, education expenses, or another major financial need.

Step 4: Enter the New Interest Rate

Enter the estimated annual interest rate for the new mortgage.

For example:

6.5%

The interest rate has a major effect on your monthly payment and total interest. If you are comparing actual refinance offers, use the rate quoted by the lender.

Step 5: Enter the New Loan Term

Enter the number of years you expect to take to repay the new loan.

Common examples include:

  • 15 years
  • 20 years
  • 30 years

A longer term generally produces a lower monthly payment, but it may result in more total interest over the life of the loan.

Step 6: Enter Closing Costs

Enter your estimated refinance closing costs.

For example:

$5,000

Closing costs may include lender fees, appraisal fees, title services, recording fees, and other expenses. The actual costs vary by lender, location, loan type, and transaction.

Step 7: Click Calculate

Click the Calculate button to generate your estimated results.

If the information is valid and the requested loan meets the calculator’s loan-to-value limit, the results will appear below the input fields.

Step 8: Review the Results

Review the new loan amount, cash available after costs, LTV ratio, estimated monthly payment, total interest, and total repayment.

You can then adjust the inputs to compare different cash out amounts, interest rates, or loan terms.

Practical Example: Estimating a $30,000 Cash Out Refinance

Suppose a homeowner has the following financial details:

InputExample Value
Current Home Value$350,000
Current Mortgage Balance$200,000
Cash Out Amount$30,000
New Interest Rate6.5%
New Loan Term30 years
Closing Costs$5,000

Step 1: Calculate the New Loan Amount

The calculator adds the current mortgage balance and desired cash out amount:

$200,000 + $30,000 = $230,000

The estimated new loan amount is $230,000.

Step 2: Calculate Cash Available After Costs

The requested cash out amount is $30,000, and closing costs are $5,000:

$30,000 − $5,000 = $25,000

The estimated cash available after costs is $25,000.

Step 3: Calculate the Loan-to-Value Ratio

The calculator divides the new loan amount by the home’s value:

$230,000 ÷ $350,000 × 100 = 65.71%

The estimated LTV ratio is 65.71%.

Step 4: Estimate the Monthly Payment

Using a 6.5% annual interest rate and a 30-year repayment term, the calculator estimates a monthly principal-and-interest payment of approximately $1,454.32.

Step 5: Review Total Interest and Repayment

Over 30 years, the estimated total repayment is approximately $523,556, including principal and interest.

The estimated total interest is approximately $293,556.

These figures illustrate why it is important to consider both the immediate cash benefit and the long-term cost of refinancing.

This example is illustrative. Actual lender terms, fees, payment amounts, and approval requirements may differ.

Understanding Loan-to-Value Ratio

The loan-to-value ratio, commonly called LTV, compares the amount of a mortgage to the value of the property.

The formula is:

LTV=New Loan AmountHome Value×100\text{LTV} = \frac{\text{New Loan Amount}}{\text{Home Value}} \times 100LTV=Home ValueNew Loan Amount​×100

For example:

230,000350,000×100=65.71%\frac{230,000}{350,000} \times 100 = 65.71\%350,000230,000​×100=65.71%

A lower LTV generally means you are borrowing a smaller percentage of your home’s value.

The calculator uses an 80% LTV limit. If the new loan amount exceeds 80% of the entered home value, the calculator displays an error and asks you to reduce the cash out amount.

This limit is a calculation rule built into the tool. Actual cash out refinance requirements vary by lender, loan program, property type, occupancy, credit profile, and other factors.

How the Calculator Estimates Your Monthly Payment

The calculator uses the standard fixed-rate mortgage payment formula.

The formula is:

M=P×r(1+r)n(1+r)n1M = P \times \frac{r(1+r)^n}{(1+r)^n-1}M=P×(1+r)n−1r(1+r)n​

Where:

  • M = Monthly payment
  • P = New loan principal
  • r = Monthly interest rate
  • n = Total number of monthly payments

The annual interest rate is converted into a monthly rate, and the loan term is converted into months.

For example, a 30-year loan has:

30 × 12 = 360 monthly payments

The calculator also handles a 0% interest rate by dividing the loan amount equally across the number of months.

The estimated payment represents principal and interest only. It does not include property taxes, homeowners insurance, mortgage insurance, HOA fees, or other housing expenses.

Benefits of Using a Cash Out Mortgage Calculator

1. Estimate Your Borrowing Amount

The calculator helps you understand how your current mortgage balance and desired cash withdrawal combine into a new loan amount.

2. See Cash Available After Closing Costs

The requested cash out amount is not always the amount you receive in hand. Subtracting estimated closing costs provides a more realistic starting estimate.

3. Compare Loan Terms

You can compare a 15-year loan with a 30-year loan to see how the repayment period affects monthly payments and total interest.

4. Understand the LTV Ratio

The calculator helps you see how much of your home’s value would be represented by the new mortgage.

5. Estimate Long-Term Interest

A refinance may provide useful cash today, but the new loan can create substantial interest costs over time. The calculator makes those costs easier to review.

6. Support Financial Planning

You can use the results as a starting point when considering home renovations, debt consolidation, emergency expenses, or other financial goals.

7. Compare Different Scenarios

Try different interest rates, cash out amounts, and loan terms to understand how each change affects the estimated results.

Important Factors to Consider Before Cash Out Refinancing

Interest Rate Changes

If your new mortgage rate is higher than your existing rate, refinancing may increase your monthly payment or total interest cost, even if you receive cash.

Closing Costs

Closing costs reduce the amount of cash you actually receive. Some lenders may offer options to roll costs into the loan, but that increases the amount borrowed.

Loan Term

A longer loan term may lower the monthly payment while increasing the total interest paid over time.

Home Equity

Your available equity depends on your home’s value and current mortgage balance. The calculator uses these figures to determine the new loan amount and LTV.

Credit and Income

Lenders generally review credit history, income, debts, and other financial information before approving a refinance.

Property Value

The actual appraised value may differ from your estimate. A lower valuation could reduce the amount you can borrow.

Financial Purpose

Consider whether the cash out amount is being used for an expense that supports your financial goals. Since the new loan is secured by your home, borrowing should be approached carefully.

Tips for Using the Calculator Effectively

  • Use realistic home values: An inflated property value can make the results misleading.
  • Enter your actual mortgage balance: Check a recent mortgage statement if necessary.
  • Compare multiple rates: Even a small rate difference can affect long-term costs.
  • Test different loan terms: Compare monthly affordability with total repayment.
  • Include estimated closing costs: This gives you a clearer picture of your net cash.
  • Review the LTV ratio: A higher loan amount relative to property value may affect available refinance options.
  • Remember additional housing costs: Taxes, insurance, and other expenses are not included in the monthly payment estimate.
  • Compare lender offers: Use the calculator as a planning tool, then review official loan estimates before making a decision.

Cash Out Refinance vs. Other Ways to Access Home Equity

A cash out refinance is one way to access home equity, but it is not the only option.

OptionGeneral Description
Cash Out RefinanceReplaces the existing mortgage with a larger loan and provides cash from the difference
Home Equity LoanProvides a separate loan secured by home equity, often with a fixed payment
HELOCProvides a revolving credit line secured by home equity, usually with a variable interest rate
Personal LoanAn unsecured loan that does not directly use home equity as collateral

Each option has different rates, fees, repayment structures, and risks. A cash out refinance may be useful in some situations, but it can also change the terms of your existing mortgage.
