A cash-out refinance allows homeowners to replace an existing mortgage with a new, larger mortgage and potentially use part of their home equity as cash. The amount available depends on several factors, including the home’s current value, outstanding mortgage balance, maximum loan-to-value ratio, closing costs, interest rate, and new loan term.
Refinance With Cash Out Calculator
Because all of these factors can affect the amount you borrow and the cost of the new mortgage, estimating the numbers before exploring a refinance can be helpful. The Refinance With Cash Out Calculator is designed to make this process easier by providing a quick estimate based on the information you enter.
The calculator estimates the maximum new loan, the amount of cash available before closing costs, the cash received after costs, the estimated monthly principal and interest payment, the total interest over the loan term, and the estimated total loan cost.
For homeowners considering using equity for renovations, debt consolidation, education expenses, major purchases, or other financial needs, these calculations can provide a useful starting point for understanding how a cash-out refinance may affect the mortgage.
However, a calculator estimate is not the same as an actual lender offer. The amount you can borrow, interest rate you qualify for, fees, and other loan conditions can vary based on your financial and property circumstances.
What Is a Cash-Out Refinance?
A cash-out refinance replaces an existing mortgage with a new mortgage that is larger than the amount currently owed, subject to applicable lending limits and qualification requirements.
The difference between the new mortgage and the existing mortgage can potentially be received as cash, after applicable costs.
For example, imagine a home is worth $400,000 and the homeowner currently owes $220,000. If a hypothetical maximum loan-to-value limit allows a new mortgage of $320,000, the difference between the new loan and the existing mortgage would be $100,000 before closing costs.
In simplified form:
Potential Cash Before Costs = Maximum New Loan − Current Mortgage Balance
If the refinancing costs were $6,000, the estimated amount remaining after those costs would be:
$100,000 − $6,000 = $94,000
The actual amount available depends on the loan program, lender requirements, property value, existing liens, borrower qualifications, and other factors.
How the Refinance With Cash Out Calculator Works
This calculator uses six primary inputs:
- Current home value
- Current mortgage balance
- Maximum loan-to-value ratio
- New mortgage interest rate
- New loan term
- Closing costs
It then produces six results:
- Maximum New Loan
- Cash Available Before Costs
- Cash Received After Costs
- New Monthly Principal & Interest
- Total Interest Over Loan Term
- Estimated Total Loan Cost
Together, these figures can help you understand the relationship between your home equity, potential cash proceeds, and the cost of the replacement mortgage.
How to Use the Refinance With Cash Out Calculator
Using the calculator is straightforward. Follow these steps for an estimate.
Step 1: Enter Your Current Home Value
Start by entering the estimated current market value of your home.
For example, if you believe your home is currently worth $450,000, enter:
$450,000
The home value is important because the calculator uses it to determine the maximum new loan based on the maximum LTV percentage you enter.
For the most useful estimate, use a realistic current value rather than the price you originally paid for the property.
Step 2: Enter Your Current Mortgage Balance
Enter the amount you currently owe on your mortgage.
For example:
$275,000
This should be your current outstanding mortgage balance, not your original loan amount.
You can generally find the current balance on a recent mortgage statement or through your loan servicer's account information.
Step 3: Enter the Maximum LTV
Enter the maximum loan-to-value ratio you want the calculator to use.
The calculator starts with a default of 80%, but you can change it.
For example:
80% LTV
Loan-to-value is a percentage that compares the mortgage amount with the home's value.
A higher allowable LTV produces a higher potential maximum loan amount, while a lower LTV produces a lower maximum loan amount.
Step 4: Enter the New Mortgage Interest Rate
Enter the annual interest rate you are considering for the new mortgage.
For example:
6.25%
The interest rate has a major impact on the estimated monthly payment and total interest over the life of the loan.
If you are comparing multiple refinance offers, you can run the calculator with different rates to see how the results change.
Step 5: Enter the New Loan Term
Enter the proposed term of the new mortgage in years.
The default is 30 years, but you can enter another term within the calculator's supported range.
For example:
- 15 years
- 20 years
- 25 years
- 30 years
A longer term generally spreads repayment across more monthly payments, while a shorter term concentrates repayment into fewer payments.
Step 6: Enter Closing Costs
Enter your estimated refinancing closing costs.
For example:
$7,000
Closing costs can include various expenses associated with completing the refinance. The exact charges depend on the lender, loan type, location, property, and transaction.
The calculator subtracts these costs from the potential cash available to estimate cash received after costs.
Step 7: Click Calculate
After entering the information, select Calculate.
The calculator will display the estimated maximum loan amount, cash availability, monthly payment, total interest, and total loan cost.
Understanding Loan-to-Value Ratio
Loan-to-value, commonly called LTV, is one of the most important concepts in a cash-out refinance calculation.
The basic formula is:
LTV = Loan Amount ÷ Home Value × 100
For example, suppose:
- Home value = $500,000
- New mortgage = $400,000
Then:
$400,000 ÷ $500,000 × 100 = 80%
The resulting LTV is 80%.
The calculator uses your selected maximum LTV to estimate the largest new mortgage permitted under the assumption you entered.
Maximum New Loan Formula
The first major calculation is:
Maximum New Loan = Current Home Value × Maximum LTV
Suppose your home is worth $450,000 and you enter an 80% maximum LTV.
The calculation is:
$450,000 × 0.80 = $360,000
The estimated maximum new mortgage would therefore be $360,000.
This does not mean a lender will necessarily approve that exact amount. It is simply the mathematical result of the home value and LTV assumption entered into the calculator.
Cash Available Before Closing Costs Formula
Once the maximum new loan is determined, the calculator subtracts the current mortgage balance.
The formula is:
Cash Available Before Costs = Maximum New Loan − Current Mortgage Balance
For example:
- Maximum new loan = $360,000
- Current mortgage balance = $250,000
Therefore:
$360,000 − $250,000 = $110,000
The estimated cash available before closing costs is $110,000.
This amount represents the theoretical difference between the maximum new mortgage and the existing mortgage balance under the calculator's assumptions.
Cash Received After Costs Formula
Closing costs reduce the amount of cash available.
The formula is:
Cash Received After Costs = Cash Available Before Costs − Closing Costs
Suppose the potential cash before costs is $110,000 and estimated closing costs are $7,000:
$110,000 − $7,000 = $103,000
The estimated cash received after costs would therefore be $103,000.
The calculator does not allow the displayed cash-after-costs figure to fall below zero.
Monthly Mortgage Payment Formula
The calculator estimates the new monthly principal-and-interest payment using the standard fixed-rate mortgage payment formula.
The formula is:
M = P × [r(1+r)^n] ÷ [(1+r)^n − 1]
Where:
- M = monthly principal and interest payment
- P = new loan amount
- r = monthly interest rate
- n = total number of monthly payments
The annual interest rate is converted to a monthly rate:
Monthly Rate = Annual Rate ÷ 100 ÷ 12
The loan term is converted to the number of monthly payments:
Number of Payments = Loan Term × 12
For example, a 30-year mortgage has:
30 × 12 = 360 payments
The calculator also accounts for a 0% interest rate separately by dividing the loan amount by the number of payments.
Total Interest Formula
After calculating the monthly payment, the calculator estimates the total amount paid over the loan term:
Total Payments = Monthly Payment × Number of Payments
Then it estimates total interest:
Total Interest = Total Payments − Loan Amount
For example, if the monthly payment were $2,500 over 360 months:
$2,500 × 360 = $900,000
If the loan amount were $400,000:
$900,000 − $400,000 = $500,000
The estimated total interest would be $500,000.
This illustrates why looking only at the monthly payment can be misleading. A lower monthly payment does not necessarily mean a lower total borrowing cost.
Example: Refinance With Cash Out
Consider a homeowner with the following hypothetical situation:
| Input | Example |
|---|---|
| Current home value | $500,000 |
| Current mortgage balance | $275,000 |
| Maximum LTV | 80% |
| New mortgage rate | 6.25% |
| New loan term | 30 years |
| Closing costs | $7,500 |
Step 1: Calculate the Maximum New Loan
The formula is:
$500,000 × 80% = $400,000
So the estimated maximum new mortgage is:
$400,000
Step 2: Calculate Cash Before Costs
Subtract the existing mortgage:
$400,000 − $275,000 = $125,000
The estimated cash available before closing costs is:
$125,000
Step 3: Subtract Closing Costs
Now subtract the estimated $7,500 closing costs:
$125,000 − $7,500 = $117,500
The estimated cash received after costs is:
$117,500
The calculator then uses the $400,000 new loan amount, 6.25% annual interest rate, and 30-year term to estimate the monthly principal-and-interest payment and total interest.
This example demonstrates how home value, existing debt, LTV, and closing costs work together.
What Can You Use Cash-Out Refinance Funds For?
Homeowners may consider cash-out refinancing for a variety of purposes. The appropriate use depends on individual circumstances and the terms of the loan.
Common potential uses include:
Home Improvements
Funds may be used for remodeling, repairs, additions, kitchens, bathrooms, roofing, or other improvements.
Debt Consolidation
Some borrowers consider using home equity to consolidate higher-interest debts. However, converting unsecured debt into mortgage debt can change the risks involved because the mortgage is secured by the home.
Education Expenses
Cash may potentially be used toward tuition or other educational expenses.
Large Planned Expenses
Some homeowners may consider using equity for major expenses that they have planned and budgeted for.
Investment Purposes
Some borrowers may explore using borrowed funds for investments. This involves additional financial risk and should be evaluated carefully.
Benefits of Using a Cash-Out Refinance Calculator
A calculator cannot determine whether refinancing is appropriate for you, but it can make the numbers easier to understand.
Estimate Available Equity
By entering the home value and mortgage balance, you can see the relationship between your property value and existing debt.
Understand LTV
The calculator makes it easy to see how changing the maximum LTV changes the potential new loan.
Estimate Cash Proceeds
You can estimate how much cash may remain after accounting for the current mortgage and closing costs.
Estimate Monthly Payments
The calculator provides an estimate of the principal-and-interest payment associated with the new loan.
Compare Loan Terms
Testing different terms can demonstrate how changing the repayment period affects monthly payments and total interest.
Understand Long-Term Interest
The total-interest result highlights the long-term cost associated with the estimated loan.
Factors That Can Affect Your Actual Cash-Out Refinance
Calculator results are based on assumptions. Actual refinancing can involve additional factors.
Credit Profile
Lenders may evaluate credit history and credit scores when determining eligibility and pricing.
Income and Debt
Income, employment, existing debts, and debt-to-income ratios can affect qualification.
Property Value
The lender may use an appraisal or another approved valuation method to determine the property's value.
Existing Liens
Second mortgages, home equity loans, tax liens, or other obligations can affect available equity.
Loan Program
Different mortgage programs can have different requirements and restrictions.
Interest Rate
The rate you actually receive may differ from the rate entered into the calculator.
Closing Costs
Actual costs may be higher or lower than the estimate entered into the calculator.
Cash-Out Refinance vs. Home Equity Loan
A cash-out refinance and a home equity loan can both provide access to home equity, but they work differently.
A cash-out refinance generally replaces the existing mortgage with a new mortgage.
A home equity loan is generally an additional loan secured by the home while the original mortgage remains in place.
This means the two options can have different payment structures, interest rates, fees, and long-term costs.
Another option is a home equity line of credit, commonly known as a HELOC, which typically provides access to a revolving credit line rather than a single lump-sum loan.
Comparing the total costs and repayment terms of available options is important.
How to Get More Accurate Calculator Results
For a more useful estimate, take time to collect accurate information before entering numbers.
Use a Recent Mortgage Statement
A recent statement can provide your outstanding principal balance and current loan information.
Use a Realistic Home Value
An outdated purchase price may not reflect current market value.
Estimate Closing Costs Carefully
Ask potential lenders for detailed cost estimates rather than relying on a rough percentage.
Test Multiple Interest Rates
Rates can have a significant effect on monthly payments and long-term interest.
Compare Multiple Loan Terms
Run the calculator using both shorter and longer terms to see how the results change.
Consider the Purpose of the Cash
Before borrowing against home equity, determine exactly how much cash is needed and why.
Look Beyond the Monthly Payment
A lower monthly payment may result from extending the loan term. Always consider total interest and total loan cost as well.
Important Limitations
The Refinance With Cash Out Calculator is an estimation tool. It does not determine actual loan eligibility or guarantee that a lender will approve the calculated amount.
The calculator assumes that the maximum new loan is determined directly from the home value and maximum LTV entered. Actual lenders may impose additional restrictions.
The monthly payment shown represents principal and interest. It does not necessarily include property taxes, homeowners insurance, mortgage insurance, HOA dues, or other housing expenses.
The calculated total loan cost represents the total scheduled principal and interest payments based on the estimated loan. It should not be interpreted as a complete measure of every expense associated with homeownership.
Frequently Asked Questions
1. What is a Refinance With Cash Out Calculator?
It is a tool that estimates how much you may be able to borrow through a cash-out refinance and how the proposed loan could affect monthly payments and total interest.
2. How is the maximum new loan calculated?
The calculator multiplies the current home value by the maximum LTV percentage entered.
Maximum New Loan = Home Value × Maximum LTV
3. What does LTV mean?
LTV stands for loan-to-value. It compares the mortgage amount with the value of the property and is expressed as a percentage.
4. How is cash available before costs calculated?
The calculator subtracts your current mortgage balance from the estimated maximum new loan.
Cash Before Costs = Maximum New Loan − Current Mortgage Balance
5. How are closing costs handled?
Closing costs are subtracted from the estimated cash available before costs to calculate the estimated cash received after costs.
6. Can I use this calculator for a 15-year refinance?
Yes. Enter 15 as the new loan term to estimate the payment and interest for a 15-year loan.
7. Does the calculator include taxes and insurance?
No. The monthly result represents estimated principal and interest only. Taxes, insurance, HOA fees, and other expenses are not included.
8. What happens if my closing costs are high?
Higher closing costs reduce the amount of cash available after costs. They can also affect the overall economic cost of refinancing.
9. Does a higher home value increase potential cash-out?
Generally, under the calculator's formula, a higher home value increases the maximum new loan at the same LTV percentage. Actual lending rules may impose additional requirements.
10. What happens if I owe more than the calculated maximum loan?
The calculator limits the cash available before costs to zero when the current mortgage balance exceeds the calculated maximum new loan.
11. Is the calculated cash amount guaranteed?
No. It is an estimate based on the numbers entered. Actual loan availability depends on lender requirements, property valuation, borrower qualifications, loan program rules, and other factors.
12. Does a longer loan term lower the monthly payment?
A longer term can spread repayment over more months and may therefore produce a lower scheduled principal-and-interest payment, but it can also result in more total interest over the life of the loan.
13. Why is total interest important?
Total interest shows how much interest could accumulate over the full repayment period based on the entered assumptions. It helps put the monthly payment into a longer-term context.
14. Can I use cash-out refinance funds for home improvements?
Cash-out funds can potentially be used for home improvements, subject to the loan terms and applicable requirements. The calculator itself does not restrict how funds are used.
15. Should I rely only on this calculator before refinancing?
No. Use it as a planning tool. For an actual refinance, compare formal loan offers, interest rates, closing costs, repayment terms, and other applicable conditions.
Final Thoughts
A Refinance With Cash Out Calculator can make it easier to understand how home value, mortgage balance, LTV, interest rate, loan term, and closing costs interact.
The most important concept is that available equity is not necessarily the same as cash you can receive. The calculator first estimates a maximum new mortgage using the home's value and selected LTV. It then subtracts the current mortgage balance to determine potential cash before costs and subtracts closing costs to estimate cash received afterward.
At the same time, increasing the new loan amount can increase monthly payments and total interest. Choosing a longer term may reduce the monthly payment while increasing the number of payments and potentially the total interest paid.
For that reason, it is useful to evaluate all of the calculator's results together rather than focusing on just one number. Try different home values, LTV percentages, interest rates, loan terms, and closing-cost assumptions to understand how sensitive the results are.
Most importantly, remember that the calculator provides estimates based on the information entered. Actual cash-out refinancing terms depend on the lender, property, borrower qualifications, loan program, market conditions, appraisal, fees, and other factors. A formal loan estimate and detailed comparison of costs should be reviewed before proceeding with a refinance.
