  "summary": "Split dues or program revenue fairly between national and local chapters.",
  "description": "Federated nonprofits and associations with local chapters need a revenue split formula that's consistent, transparent, and covers what each level actually does, national typically handling brand, insurance, national advocacy, and shared technology while chapters handle direct member programming. This calculator takes total membership or program revenue collected, applies a national share percentage, and shows the resulting split along with what that leaves each individual chapter on a per-member basis, so you can sanity-check whether the split leaves local chapters enough to actually run programming or whether it's structurally starving them while national retains too much.",
  "formula": "National share = total revenue × national %; chapter share = remainder ÷ number of chapters or per member.",

  "faq": [
    {
      "q": "What's a typical national/chapter split?",
      "a": "It varies widely by sector, but 25-40% retained by national with the remainder flowing to chapters is common among federated membership associations, adjusted based on how much direct member-facing programming national provides versus purely back-office and brand functions."
    },
    {
      "q": "Should the split be based on where dues are collected or where members are located?",
      "a": "Location-based splitting (each member's home chapter gets its share) is more common and transparent than collection-point splitting, which can create disputes if dues are processed centrally but service delivery happens locally through a different chapter."
    },
    {
      "q": "How do we handle chapters with very different sizes?",
      "a": "A flat per-chapter split ignores that a 500-member chapter has vastly different program costs than a 20-member chapter. Per-member splitting is usually fairer and is what this calculator's per-member output reflects, use it alongside the flat average, not instead of it."
    },
    {
      "q": "What if small chapters can't cover basic operations on their share?",
      "a": "Many federated structures add a minimum chapter subsidy or shared services model (national-provided insurance, templates, bulk-purchased software) specifically so struggling small chapters aren't structurally set up to fail on a pure percentage split alone."
