Cash-Out Refinance Calculator Guide

How to calculate your available equity, what cash-out costs, and when it's worth doing

What Is a Cash-Out Refinance?

A cash-out refinance replaces your existing mortgage with a new, larger loan. The difference between what you owe and the new loan amount is paid to you in cash at closing. Unlike a home equity loan or HELOC — which add a second lien on top of your existing mortgage — a cash-out refi is a single first-mortgage transaction.

Homeowners use cash-out refinances to fund home renovations, consolidate high-interest debt, cover large expenses (medical, education, business), or build an emergency fund. The proceeds are tax-free because they represent borrowed money, not income.

The Core Formula: How Much Can You Access?

Lenders limit how much you can borrow based on your loan-to-value (LTV) ratio. Most conventional lenders cap cash-out refinances at 80% LTV:

Maximum new loan = Home value × 80%
Maximum cash out = Maximum new loan − Current mortgage balance

Example — Home valued at $550,000

Home Value
$550,000
80% LTV Limit
$440,000
Current Balance
$310,000
Max Cash Out
$130,000

New loan: $440,000. Current balance: $310,000. Available equity (cash out): $440,000 − $310,000 = $130,000.

LTV Limits by Loan Type

Loan Type Max LTV (Cash-Out) Notes
Conventional (Fannie/Freddie)80%Applies to primary residences
FHA Cash-Out80%Must have owned 12+ months
VA Cash-Out90%Veterans/active military only
Investment property70–75%Stricter underwriting
Second home75%Higher rate premium applies
State-specific LTV rules: A few states layer additional restrictions on top of these guidelines. Texas imposes a constitutional 80% LTV cap on primary homestead cash-out refinances under Section 50(a)(6) — the same ceiling as conventional, but legally mandated regardless of lender or loan type, and it applies to the entire equity position at closing. California cash-out refinances are recourse obligations that do not carry the purchase-money anti-deficiency protection of CCP §580b — important if property values decline after you close. See the state-by-state refinance guide for more.

How a Cash-Out Refi Affects Your Monthly Payment

Your new payment is based on the larger loan balance — even if the new rate is lower, you're borrowing more, so your payment usually increases. Here's a realistic comparison:

Before vs. After Cash-Out Refinance

Before: Balance
$310,000
Before: Rate
7.25%
Before: Payment
$2,117/mo
After: Balance
$440,000
After: Rate
6.75%
After: Payment
$2,855/mo

Payment increases by $738/mo despite a lower rate because the loan balance jumped by $130,000. The cash received partially offsets this — the real cost is the interest on the additional $130,000.

What Does a Cash-Out Refinance Cost?

Cash-out refinances carry the same closing costs as a standard rate-and-term refinance — typically 2–5% of the new loan amount. On a $440,000 new loan, expect $8,800–$22,000 in closing costs. Specific fees include:

  • Origination fee: 0.5–1% of the loan ($2,200–$4,400)
  • Appraisal: $400–$700 (required to establish the home's current value)
  • Title insurance and search: $1,000–$2,500
  • Recording and government fees: $200–$800
  • Prepaid interest and escrow setup: $2,000–$5,000

These costs reduce your net cash received. If you take $130,000 in cash but pay $12,000 at closing, your net is $118,000. Most lenders let you roll closing costs into the new loan, but then you pay interest on them for the life of the loan.

Cash-Out Rate Premium

Cash-out refinances carry a higher rate than rate-and-term refinances — typically 0.125% to 0.5% higher because the lender views a higher LTV as slightly more risk. If rate-and-term refis are quoted at 6.50%, expect cash-out rates of 6.625%–7.00% depending on your credit profile and LTV.

Smart Uses vs. Risky Uses

Use of FundsAssessment
Home renovation (adds value)Generally sound — increases equity and improves living conditions
Paying off high-interest credit cardsCan make sense if you address spending habits; converts unsecured to secured debt
Investment property down paymentModerate risk — amplifies leverage across two properties
College tuitionConsider federal student loans first; those have no collateral risk
Vacation or luxury purchaseHigh risk — you're borrowing against your home for a depreciating/consumed asset
Starting a businessHigh risk — business failure can threaten your home

Cash-Out Refi vs. HELOC: Which Is Better?

Both let you access home equity. The right choice depends on your rate environment and how you'll use the money:

  • Choose cash-out refi if you want a single fixed-rate loan, are refinancing your first mortgage anyway, or want a lump sum at a predictable payment.
  • Choose HELOC if you need flexible, draw-as-needed access (like for a renovation over 18 months), want to keep your existing first mortgage rate, and can tolerate a variable rate.

If you locked in a mortgage at 3.5% in 2021, a cash-out refi would replace that with today's higher rates on the full balance. A HELOC leaves your first mortgage untouched and adds a second loan only for the equity you need.

Qualifying for a Cash-Out Refinance

Lenders evaluate the same factors as any refinance, with a few additional requirements:

  • Credit score: Minimum 620 for conventional; 680+ for better rates
  • Equity: Must retain at least 20% equity after the cash-out (80% LTV max)
  • Debt-to-income ratio: Generally 43% or lower including the new payment
  • Seasoning: Most lenders require 6–12 months of on-time payments on the current loan
  • Appraisal: An appraisal is almost always required to confirm the home's value

Frequently Asked Questions

How much can I cash out in a cash-out refinance?

Most lenders cap you at 80% of your home's appraised value. Subtract your current mortgage balance from that figure to find your maximum cash-out amount. On a $550,000 home with a $310,000 balance, the maximum is $130,000.

Is a cash-out refinance a good idea?

It depends on what you use it for and what rate you qualify for. Funding value-adding home improvements or eliminating high-rate debt can be smart. Funding lifestyle spending or volatile investments with your home as collateral adds significant risk.

How does a cash-out refinance affect my monthly payment?

Your new payment is based on the larger loan balance. Even at a lower interest rate, borrowing significantly more usually increases your monthly payment. Run the numbers before assuming the payment will be manageable.

What is the difference between a cash-out refinance and a HELOC?

A cash-out refi replaces your entire mortgage with a new, larger loan. A HELOC is a revolving second loan that leaves your first mortgage in place. If you have a low-rate first mortgage, a HELOC lets you access equity without replacing it.
