  • Using the future value formula, the projected U.S. consumer spend per generation can be determined as follows FV = PV (1 + r)^n, whereby
    • FV — Future value
    • PV — Present value
    • r — Rate of return
    • n — No. of periods
  • Gen Z: $44 billion (1 + 0.019)^5 = $48.34 billion
  • Millennials: $322.5 billion (1 + 0.019)^5 = $354.32 billion
  • Gen X: $357 billion (1 + 0.019)^5 = $392.23 billion
  • Baby Boomers: $548.1 billion (1 + 0.019)^5 = $602.2 billion.
  • Silent Generation: $162.9 billion (1 + 0.019)^5 = $179 billion
  • Gen Z: $44 billion (1 + 0.019)^10 = $53.11 billion
  • Millennials: $322.5 billion (1 + 0.019)^ 10 = $389.3 billion
  • Gen X: $357 billion (1 + 0.019)^10 = $430.93 billion
  • Baby Boomers: $548.1 billion (1 + 0.019)^ 10 = $661.61 billion.
  • Silent Generation: $162.9 billion (1 + 0.019)^ 10 = $196.64 billion
