Summary:
Your maximum cash-out refinance amount depends on your home’s current value, your outstanding mortgage balance, and your lender’s loan-to-value (LTV) limit. Most lenders allow you to borrow up to 80% of your home’s appraised value, minus what you still owe. This guide shows you how to calculate your potential cash-out amount, understand lender limits, and avoid overborrowing.

What Determines Your Cash-Out Limit
- Home value: Determined by an appraisal ordered by your lender.
- Loan-to-value (LTV) ratio: Most lenders cap cash-out refinances at 80% LTV for primary residences.
- Mortgage balance: The lower your remaining loan balance, the more equity you can potentially access.
- Credit and debt-to-income (DTI): Strong credit and manageable DTI can help you qualify for the maximum allowed amount.
Quick formula:
(Appraised Home Value × Maximum LTV) − Current Mortgage Balance = Estimated Cash-Out Amount.
(Appraised Home Value × Maximum LTV) − Current Mortgage Balance = Estimated Cash-Out Amount.
Step-by-Step Calculation Example
| Step | Example | Result |
|---|---|---|
| 1. Determine your appraised value | $400,000 | |
| 2. Apply lender’s max LTV (80%) | $400,000 × 0.80 | $320,000 (maximum new loan) |
| 3. Subtract your existing mortgage balance | $320,000 − $250,000 | $70,000 cash-out potential |
Factors That Affect How Much You Can Cash Out
- Property type: Second homes and investment properties often have stricter LTV limits (typically 70–75%).
- Credit score: Higher scores can unlock higher LTVs and better rates.
- Occupancy: Primary residences generally qualify for the most favorable cash-out limits.
- Loan program: FHA, VA, and conventional loans each have their own LTV and eligibility rules.
Typical LTV Limits by Loan Type
| Loan Type | Max LTV for Cash-Out | Notes |
|---|---|---|
| Conventional (Primary Home) | 80% | Most common limit for cash-out refinances |
| FHA Cash-Out Refinance | 80% | Must meet FHA credit and insurance requirements |
| VA Cash-Out Refinance | Up to 90% | For eligible veterans and service members |
| Investment Property | 70–75% | Higher risk means lower allowable LTV |
Hidden Costs to Factor In
- Closing costs: Typically 2%–5% of the loan amount; these reduce your net cash-out.
- Prepayment penalties: Check if your current mortgage has one before refinancing.
- Appraisal and origination fees: Usually paid upfront or rolled into the new loan.
Pro tip: Always calculate your “net cash” after fees, not just your gross cash-out amount.

FAQs
How do I know my home’s current value?
Your lender will order a professional appraisal, but you can estimate it using recent comparable sales or online valuation tools.

Only some government-backed loans (like VA cash-out refinances) allow up to 90% LTV. Conventional and FHA loans typically cap at 80%.
Does my credit score affect how much I can cash out?
Yes. Stronger credit may help you qualify for the maximum LTV limit and better rates, increasing your total accessible cash.
