  "summary": "How many alignments it takes to pay off a new rack, and what it does to monthly profit after.",
  "description": "An alignment rack is a five-figure equipment purchase that only pays for itself if you can actually fill the bay with alignment work, which competes with general repair for the same floor space. This calculator takes the all-in equipment cost (rack, lift compatibility work, targets, software, installation), your per-alignment margin, and expected monthly volume to compute payback period and post-payback monthly profit contribution. It also flags the breakeven volume — the minimum alignments per month needed to cover financing or opportunity cost of the bay space. Shops considering a rack should model conservative volume first (what you can book from existing tire and suspension customers) before counting on new alignment-only customers who rarely materialize without dedicated marketing.",
  "formula": "Payback (months) = Equipment Cost ÷ (Monthly Alignments × Margin per Alignment). Monthly Profit = (Monthly Alignments × Margin) − Financing Payment.",

    {
      "q": "What's a realistic payback target?",
      "a": "12-24 months is typical for a shop already doing tire and suspension work in-house. Longer than 36 months usually means the volume assumption is too optimistic relative to your actual car count and should be revisited before buying."
    },
    {
      "q": "What volume assumption should I use?",
      "a": "Count alignments you're currently sending out or turning away, plus a conservative estimate of tire sales that would naturally attach an alignment (roughly 25-35% attach rate on 4-tire sales is a reasonable planning number, not a guarantee)."
    },
    {
      "q": "Does the rack replace a general repair bay?",
      "a": "Only if it's installed on a dedicated lift. If it's portable or shares a bay with general repair, model the opportunity cost of that bay's lost general-repair hours against the alignment margin it generates instead of assuming the bay is free capacity."
    },
    {
      "q": "Should I include tire sales margin in the payback math?",
      "a": "Keep them separate. The rack's payback should stand on alignment margin alone; tire sales would likely happen with or without the rack via outsourced alignment, so crediting the rack with tire margin overstates its actual payback speed."
