    {
      "q": "What does this estimate calculator do?",
      "a": "It creates a low, midpoint, and high air freight budget using chargeable weight, route/service rate bands, local charges, and a planning buffer."
    },
    {
      "q": "How is this different from the quote calculator?",
      "a": "This is an earlier planning page for ranges. Use the quote calculator when you have forwarder line items and want to rebuild an all-in quote."
    },
    {
      "q": "How is chargeable weight estimated?",
      "a": "The calculator compares actual gross weight with CBM converted at 166.7 kg per CBM, which matches the 6000 cm3/kg air freight divisor."
    },
    {
      "q": "Should I use the low or high estimate?",
      "a": "Use the midpoint for rough budgeting and the high estimate for cash planning, launch deadlines, or inventory decisions."
    },
    {
      "q": "Does this replace a forwarder quote?",
      "a": "No. It is a pre-quote planning range. Live quotes can move with capacity, fuel, commodity type, and destination delivery details."
    },
    {
      "q": "What should local charges include?",
      "a": "Include expected origin handling, destination handling, documentation, clearance, pickup, and delivery when you need a door-to-door budget."
