  "summary": "Compute payback period and annual return on a new or used vending machine purchase.",
  "description": "Buying a vending machine is a capital outlay judged the same as any small equipment investment: purchase price plus first stocking load against the net cash it throws off monthly. This calculator takes machine cost, monthly gross sales estimate, product cost percentage, location commission, and a monthly service cost estimate (restocking labor, card reader fees, minor repairs) to compute monthly net cash flow, payback period in months, and annualized ROI on the initial investment. Use it to compare a $3,500 refurbished combo machine against a $9,000 new smart vending unit with telemetry and cashless payment before committing capital.",
  "formula": "Monthly net cash flow = sales × (1 − product cost % − commission %) − service cost. Payback months = machine cost ÷ net cash flow. Annual ROI = (net cash flow × 12) ÷ machine cost.",

  "faq": [
    {
      "q": "Is a new smart vending machine worth the extra cost over used?",
      "a": "Telemetry (remote sales and inventory monitoring) and cashless payment typically lift sales 15-30% versus a cash-only older unit and cut wasted restocking trips, which often more than offsets the higher purchase price within the first 12-18 months if the location has decent traffic."
    },
    {
      "q": "What payback period should I target?",
      "a": "12-24 months is a strong target for a used machine in a good location; new equipment with higher upfront cost may run 18-30 months and is justified more by lower long-term maintenance and better sales data than by fast payback alone."
    },
    {
      "q": "How sensitive is ROI to commission rate?",
      "a": "Very. Moving from 0% to 20% commission on the same sales volume can cut net cash flow by more than half since commission comes straight off the top before any other cost — always negotiate commission before signing a location agreement, it matters more than a few points of product cost."
    },
    {
      "q": "Should I include financing cost if I take a loan for the machine?",
      "a": "Yes — if financed, add the monthly loan payment to service cost or compare payback period against the loan term to ensure cash flow stays positive throughout repayment rather than relying purely on the equity-free payback number this calculator shows."
