Inflation is a silent retirement risk. Underestimating it by even 1-2% can materially change your required portfolio.

Why It Matters

If spending is $60,000 today, future spending after 25 years is roughly:

  • At 2% inflation: about $98,000
  • At 4% inflation: about $160,000

Practical Inflation Modeling

  • Use base and stress inflation cases
  • Model healthcare above headline CPI
  • Avoid assuming today’s low inflation persists forever

Recommended Workflow

  1. Set baseline in Retirement Number Calculator
  2. Stress test with higher inflation assumptions
  3. Review inflation deep dive for mitigation ideas
