Cash-Out Refinance Calculator - Mortgage Equity
Estimate the new refinance loan, cash available after closing costs, and monthly principal-and-interest payment.
Enter home value, current balance, target loan-to-value, closing costs, interest rate, and term for a cash-out refinance estimate.
Cash-Out Refinance Calculator - Mortgage Equity
Estimate the new refinance loan, cash available after closing costs, and monthly principal-and-interest payment.
Maximum new loan = home value × maximum LTV. Cash out = maximum new loan - current mortgage balance - closing costs. Monthly payment uses the standard amortization formula.
About the Cash-Out Refinance Calculator
The Cash-Out Refinance Calculator is built for people who need a defensible cash-out refinance estimate without opening a spreadsheet from scratch. It uses the same inputs analysts normally collect for the calculation: home value, current mortgage balance, maximum loan-to-value, closing costs, interest rate, and term. Because the input labels map directly to the formula, the result is easy to audit when you are checking a model, explaining an assignment, or comparing two scenarios in a meeting. The goal is not to hide the math behind a black box; it is to make the assumptions visible so the output can be challenged and improved.
The calculation mechanism is straightforward: The calculator caps the new mortgage at home value multiplied by the chosen LTV, subtracts the existing balance and closing costs to estimate cash proceeds, and then applies the standard fixed-rate amortization formula for the new payment. The result panel keeps the main answer beside the supporting values so you can see whether one input is driving the conclusion. That is important for cash-out refinance work because a single stale assumption can make a reasonable-looking answer misleading. A good review process is to calculate a base case, change one input at a time, and document which assumptions came from statements, quotes, contracts, tax rules, or operating data.
Interpreting the answer requires context. Available cash rises with equity and the allowed LTV, but the new monthly payment depends on the full refinanced loan, not just the cash taken out. A zero cash-out result means the requested LTV does not leave equity after payoff and costs. The number should be compared with prior periods, peers, policy targets, or the decision threshold that matters for the situation. For planning work, it is often more useful to run a conservative case and an optimistic case than to debate one false-precision estimate. The worked examples on this page show the arithmetic with real numbers so you can sanity-check both the formula and the direction of the result.
There are also caveats. Actual lenders may use appraised value, credit overlays, reserves, occupancy rules, and rate adjustments. Compare the new payment and total interest against keeping the current loan plus a second-lien or personal-loan alternative. The calculator does not replace professional accounting, tax, legal, lending, investment, or operational advice when those rules control the decision. It is best used as a transparent first-pass estimate for home equity planning, debt consolidation comparisons, renovation budgeting, and mortgage prequalification conversations. If the result will support a contract, tax return, loan application, board package, or customer-facing claim, keep a copy of the source inputs and reconcile the estimate to the official document before relying on it.

| Inputs | Result | Notes |
|---|---|---|
| Home value $400,000; balance $250,000; 80% LTV; $5,000 costs; 6.5% for 30 years | Cash out = $65,000.00 | The new loan is $320,000 before subtracting the old balance and costs. |
| Home value $600,000; balance $350,000; 75% LTV; $8,000 costs; 6.25% for 30 years | Cash out = $92,000.00 | Lower LTV reduces leverage while still releasing equity. |
| Home value $300,000; balance $260,000; 80% LTV; $4,000 costs | Cash out = $0.00 | The current balance and costs exceed the target refinance limit. |

Cash-Out Refinance Calculator FAQ
How much equity do I need for a cash-out refinance?
Many programs require you to keep some equity after the refinance, often expressed as a maximum LTV. If the cap is 80%, the new loan cannot exceed 80% of the property value.
Are closing costs subtracted from cash out?
This calculator subtracts closing costs from the proceeds so the cash-out estimate is conservative. If costs are paid out of pocket instead, the cash received could be higher but your upfront expense rises.
Does the payment use only the cash-out amount?
No. The payment is based on the entire new mortgage balance because the old loan is replaced. This is why a modest cash-out amount can still materially change the monthly payment.
What if the result is zero cash out?
A zero result means the new loan limit is not enough to pay off the existing mortgage and costs while leaving cash proceeds. Try a lower balance, higher appraised value, lower costs, or confirm whether the lender allows a higher LTV.
Is cash-out refinancing the cheapest way to borrow?
Not always. A cash-out refinance can lower or simplify payments, but it may reset the mortgage term and add closing costs. Compare the lifetime interest with home-equity loans, HELOCs, and unsecured debt options.
