cash out refi calculator

What is a cash-out refinance?

A cash-out refinance replaces your current mortgage with a larger new mortgage, then gives you the difference in cash at closing. The amount you can borrow is usually limited by your lender’s maximum loan-to-value ratio (LTV). For many conventional loans, 80% LTV is a common ceiling, though programs and lenders differ.

Example: if your home is worth $500,000 and your lender allows 80% LTV, the maximum loan is $400,000. If your current payoff balance is $280,000, you may be able to extract equity, minus closing costs and fees.

How to use this cash out refi calculator

Step-by-step

• Enter your current home value and mortgage balance.
• Set your lender’s max LTV (often 70% to 85%, depending on loan type and credit profile).
• Optionally enter a target cash-out amount to test a specific scenario.
• Add estimated closing costs and choose whether to finance them in the new loan.
• Input your proposed new rate and term to estimate your new monthly principal-and-interest payment.
• Include your current rate and remaining term to compare old vs. new payment.

How the calculator works behind the scenes

1) Maximum new loan amount

Maximum New Loan = Home Value × Max LTV

2) Maximum cash available before costs

Gross Available Equity = Maximum New Loan − Current Mortgage Balance

3) Net cash to borrower

If costs are financed, closing costs reduce net cash proceeds. If costs are paid out-of-pocket, your cash-out amount is higher, but you bring cash to close.

4) New monthly payment estimate

Monthly payment is calculated using the standard amortization formula for principal and interest only. Property taxes, homeowners insurance, mortgage insurance, and HOA fees are excluded.

When a cash-out refinance can make sense

• High-interest debt consolidation: Replace expensive credit card debt with lower-rate mortgage debt.
• Home improvements: Fund renovations that may improve livability or resale value.
• Emergency liquidity: Access capital for major expenses when alternatives are limited.
• Investment in long-term goals: Education, business use, or other strategic spending with clear ROI.

Risks to evaluate before you refinance

• You reset your loan clock: Moving from fewer remaining years back to 30 years can raise total interest paid.
• Your rate may increase: If your existing mortgage has a low fixed rate, refinancing could raise payment.
• Closing costs matter: Typical costs can be 2% to 5% of the new loan amount.
• Your home is collateral: Missed payments can put your home at risk.
• Equity cushion shrinks: Pulling cash reduces financial flexibility if home values fall.

Cash-out refinance vs HELOC vs home equity loan

Cash-out refinance

Replaces your first mortgage with one new loan. Best when the new blended terms improve your situation overall and you want one payment.

HELOC

A revolving second lien with variable rate in many cases. Good for flexible, staged spending, but rate volatility can increase payment risk.

Home equity loan

Lump-sum second lien, often fixed rate and fixed term. Useful when you need a set amount and prefer predictable payments.

Tips to improve approval odds and pricing

• Check credit reports and fix errors before applying.
• Lower revolving debt to improve debt-to-income ratio.
• Document income thoroughly (especially self-employment income).
• Compare multiple lenders and request full Loan Estimates.
• Ask about points, lender credits, and break-even timing.

Frequently asked questions

How much equity do I need for a cash-out refinance?

Many lenders want you to keep at least 20% equity after refinancing, though exact limits vary by loan type, occupancy, and credit profile.

Can I use cash-out funds for anything?

Usually yes, including debt payoff, repairs, tuition, or major purchases. Some lenders may have documentation or seasoning requirements.

Does a cash-out refinance hurt my credit?

You may see a temporary dip from credit inquiries and a new loan account. Responsible payment behavior can help your score recover over time.

Is cash-out refinancing tax deductible?

Tax rules are situation-specific and change over time. Consult a qualified tax professional for advice about interest deductibility.
