  "summary": "Find exactly how many months until a cash-out refi's costs pay for themselves.",
  "description": "A cash-out refinance replaces your mortgage with a bigger one, pulling the difference out as cash, but it resets your rate on the entire balance, not just the cash-out portion, and comes with closing costs of roughly 2–5% of the new loan. This calculator isolates the breakeven question: given your rate change, the added interest cost of a larger balance, and the closing costs, how many months of the new higher (or lower) payment does it take before the deal has 'paid for itself' relative to just keeping your current mortgage and getting cash another way (like a HELOC or personal loan)? It also flags the pure cost of extracting the cash — since a cash-out refi doesn't just cost you closing fees, it costs you interest on the extracted amount for the life of the new loan, which a straight breakeven-on-closing-costs number often hides.",
  "formula": "Payment difference = new payment − old payment. Breakeven months = closing costs ÷ monthly payment difference (only meaningful if new payment is higher due to added balance, or savings if rate dropped significantly). Total interest cost of the cash = extracted amount financed over the remaining term at the new rate.",

  "faq": [
    {
      "q": "Why does a cash-out refi often cost more than it looks like upfront?",
      "a": "Because you're not just paying interest on the $50,000 you pulled out — if rates rose since your original loan, you're now paying the new, higher rate on your entire existing balance too, not just the cash-out amount. That rate reset on the full balance is usually the biggest hidden cost, dwarfing the closing fees."
    },
    {
      "q": "When is a HELOC or home equity loan better than a cash-out refi?",
      "a": "When your current mortgage rate is well below current market rates. A HELOC or second mortgage lets you tap equity at a new rate on just the amount borrowed, leaving your low-rate first mortgage untouched — often far cheaper than resetting the whole balance to today's rate."
    },
    {
      "q": "Does the breakeven calculation account for the tax deduction on mortgage interest?",
      "a": "No, this tool ignores tax effects since most homeowners now take the standard deduction and get no marginal benefit from mortgage interest. If you do itemize and the cash-out funds are used to substantially improve the home, consult a tax professional since deductibility rules differ from cash used for other purposes."
    },
    {
      "q": "Is there a limit on how much cash I can take out?",
      "a": "Lenders typically cap cash-out refinances at 80% loan-to-value for conventional loans (sometimes up to 85% for certain programs), meaning your new loan balance including the cash-out can't exceed that percentage of the home's appraised value."
