Cash-Out Refinance Equity & Net Proceeds Formula

Cash Out=(Vhome×LTVmax)PcurrentFees,Mnew=Pnew[r(1+r)n(1+r)n1]\text{Cash Out} = (V_{\text{home}} \times \text{LTV}_{\text{max}}) - P_{\text{current}} - \text{Fees}, \quad M_{\text{new}} = P_{\text{new}} \left[ \frac{r(1+r)^n}{(1+r)^n - 1} \right]

Calculates maximum allowable cash extraction by applying lender Loan-to-Value limits (typically 80%) to property value, subtracting the current loan payoff and estimated closing costs.
