How Our Cash-Out Refinance Calculator Works
1. Maximum New Loan At 80% LTV
Our calculator uses an 80% loan-to-value cap, which is common in cash-out refinances. That’s calculated as:
Maximum new loan = 0.80 × home value
This sets the upper borrowing limit for the refinance. If your home is worth $500,000, the maximum new loan under this model is $400,000.
2. Cash Available
Next, our calculator estimates how much cash you may be able to take out as:
Max cash-out = cap amount − current balance − closing costs
3. New Loan Amount
The calculator then determines the size of the replacement mortgage:
New loan amount = current balance + cash received + financed closing costs
That amount is still capped at 80% of the home value.
If the requested cash plus financed costs pushes the balance above the cap, the calculator limits the result.
4. New Monthly Principal And Interest Payment
Once the new loan amount is set, the calculator uses standard amortization to estimate the new monthly principal and interest payment.
This gives you a clean payment estimate based on:
- New loan amount
- Interest rate
- Loan term
5. Payment Change
The calculator compares the new monthly principal and interest payment to your current monthly principal and interest payment.
For that comparison, it assumes 30 years remaining on your existing loan.
That means the payment change is a useful directional estimate, but it may not perfectly match a borrower who has fewer than 30 years left on the current mortgage.
What To Enter Before You Run The Calculator
To get a useful result, you need realistic inputs.
Home Value
Use a reasonable estimate based on recent comparable sales, a lender estimate, or another current valuation method. If the value is too high, the available cash number will look better than it really is.
Current Mortgage Balance
This is the unpaid principal balance on your existing mortgage, not your original loan amount.
Requested Cash-Out Amount
Enter the amount you want to pull from your home equity. The calculator will reduce it if the 80% cap and closing costs do not support that figure.
Interest Rate
Use a rate that is realistic for your loan profile. A lower assumed rate can make the scenario look stronger than it would be in practice.
Loan Term
Your term affects both monthly payment and total interest cost. A longer term usually lowers the payment but can raise total borrowing cost over time.
Closing Costs
The calculator includes closing costs in the cash available math and the new loan amount math when they are financed.
How To Read The Results
Cash Available
This tells you how much equity you may be able to convert into cash after accounting for the 80% cap, your current balance, and closing costs.
New Loan Amount
This shows the full size of the replacement mortgage after adding the balance you still owe, the cash you take out, and financed closing costs.
New Monthly P&I
This tells you what the new monthly principal and interest payment would look like under the refinance scenario.
Payment Change
This compares the new monthly principal and interest payment to your current monthly principal and interest payment.
Cash-Out Refinance Alternatives
A cash-out refinance is not always the best fit.
If your current mortgage rate is already low, keeping that first mortgage and using a HELOC or home equity loan may be worth considering. If your main goal is only to reduce the interest rate on the first mortgage, a rate-and-term refinance may be a cleaner option.
Frequently Asked Questions
What Is an 80% LTV Cap in a Cash-Out Refinance?
It means the new mortgage balance cannot exceed 80% of your home’s value under this calculator model.
How Is Cash-Out Amount Calculated in a Cash-Out Refinance Calculator?
It subtracts your current mortgage balance and closing costs from the 80% cap, then limits the result to the amount you requested.
Are Closing Costs Included in a Cash-Out Refinance Calculation?
Yes. Closing costs affect both the available cash calculation and the new loan amount when they are financed.
What Does Payment Change Mean in a Cash-Out Refinance Calculator?
It compares your new monthly principal and interest payment to your current monthly principal and interest payment, assuming 30 years remaining on your existing loan.
Can a Cash-Out Refinance Calculator Tell You If Refinancing Is Worth It?
It can show whether the numbers appear workable under this model, but it cannot determine whether a refinance is the best decision for your overall financial situation.
