Cash Out Refinance Mortgage Calculator

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

  1. Home’s current estimated value
  2. Existing mortgage balance
  3. Desired cash-out amount
  4. New interest rate (APR)
  5. New loan term (years or months)
  6. (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

✅ 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.
