Formula used

  1. Compute billable cores.
    Physical: billable_host = max(sockets×cores_socket, sockets×min_socket, min_host).
    vCPU: billable_instance = max(ceil(vCPU/ratio), min_instance).
  2. Convert to packs.
    packs = ceil(total_billable_cores / pack_size).
  3. Annualize license cost.
    annual_license = packs×price_per_pack×(12 if monthly input else 1).
  4. Apply support, discount, tax, and uplift.
    Each year i: license_i = annual_license×(1+uplift)^(i−1).
    support_i = license_i×support_rate, unless included.
    discounted = (license_i+support_i)×(1−discount).
    taxed = discounted×(1+tax). Setup is added in year 1.
  5. Summaries.
    term_total = sum(year_totals). monthly_equivalent = term_total/(years×12).
Money outputs are multiplied by the exchange rate.
