A Cash‑Out Refinance Mortgage Calculator helps homeowners estimate new monthly payments, total interest, and available cash after refinancing their mortgage for a larger amount than they owe. This tool is invaluable for assessing whether tapping into home equity—while adjusting terms and rates—is financially beneficial.
Cash-Out Refinance Mortgage Calculator
- Home’s current estimated value
- Existing mortgage balance
- Desired cash-out amount
- New interest rate (APR)
- New loan term (years or months)
- (Optional) Closing costs and fees, and whether they’re rolled into the loan.
Once submitted, the calculator outputs:
- New loan balance
- Available cash after payoff and costs
- Estimated monthly mortgage payment
- Total interest paid over loan term
- Comparison to existing payment and balance
Some calculators (e.g. NerdWallet, AmeriSave, Zillow, LendingTree) allow side-by-side comparison of original vs. refinanced scenarios and even include property taxes, insurance, or HOA fees.WOWA+10NerdWallet+10Amerisave+10InvestopediaInvestopedia+3nesto.ca+3MarketWatch+3LendingTree+1nesto.ca+1InvestopediaZillow+1Investopedia+1Bank of America+1NerdWallet+1
🧮 How the Calculator Works: Loan Math Explained
The tool uses the standard amortized loan formula to estimate monthly payments:
iniCopyEditA = P × [i × (1 + i)^n] ÷ [(1 + i)^n – 1]
- A: monthly payment
- P: new loan principal (existing balance + cash-out + rolled-in costs)
- i: monthly rate = APR ÷ 12
- n: total payments = loan term × 12
This allows comparison with your current loan to see how terms shift with different rates, cash-outs, or timeframes.Calculator.netInvestopediaBankrate
📘 Real‑World Example
Current loan:
- Home value: $400,000
- Original mortgage: $200,000 (owes)
- Equity: $200,000
Refinance scenario:
- Loan-to-value limit: 80% (max refinance = $320,000)
- Desired cash-out: $40,000
- Closing costs: 3% ($9,600) rolled into loan
- New loan amount: $200,000 + 40,000 + 9,600 = $249,600
- New rate: 6.5%
- Term: 30 years
Results:
- New payment ≈ $1,576/mo (excluding taxes/insurance)
- Cash-in-hand ≈ $30,400 after pay-off and fees

✅ Considerations Before Cash‑Out Refinancing
- Interest rate premium: Cash‑out often carries ~0.25%‑0.5% higher rates than rate‑and‑term refinancing due to increased lender risk.Wikipedia+1Kiplinger+1
- LTV limits: Most lenders cap at ~80% LTV (varies with loan type—VA, FHA may differ).NerdWalletWOWA
- Closing costs: Typically 2–6% of loan value; include in break-even calculation.NerdWallet
- Qualification criteria: Require minimum credit score (~620+), DTI below ~43%, and seasoning requirements.Bankrate+1NerdWallet+1
- Equity risk: Borrowing more reduces equity cushion and increases foreclosure risk if unable to pay.
- Break-even horizon: If you don’t stay long enough to recoup fees through savings, refinance may not be worth it.
