FIRE Portfolio Protection

NAV Erosion Just Added Years to Your FI Date

Every percentage point of NAV erosion compounds against your FI timeline. A $200K position eroding 8% annually doesn't just cost you $16,000 — it costs you the compounding that $16,000 would have generated. This guide quantifies the timeline impact and gives you the forensics methodology to catch it before it matters.

Why FIRE Investors Are Especially Vulnerable to NAV Erosion

You Can't Tell If It's Working Without This Framework

A holding generating 12% distributions while eroding 8% NAV looks like success until you calculate total return. FIRE math requires tracking both numbers.

NAV Erosion Compounds Against Your FI Number Silently

If your FI number assumes a stable portfolio value, systematic NAV erosion raises that number every year. Most FIRE investors never calculate the timeline impact.

The Coverage Ratio Is the Number Your FI Math Depends On

A fund covering only 85% of its distributions from earnings is burning principal. That principal was part of your FI calculation. Now it isn't.

Is This Guide Right for You?

This guide is for you if...

  • You hold high-yield income ETFs as part of your FIRE portfolio or income layer
  • You've wondered whether a holding is actually working — or just appearing to
  • You want to quantify the timeline impact of NAV erosion on your specific FI number
  • You want the 20-ETF ranking to identify which funds belong in a FIRE-grade portfolio
  • You believe in evidence-based analysis and want the data, not opinions

This guide is NOT for you if...

  • You're a pure total-return index investor with no income ETF exposure
  • You're in accumulation mode with no current income needs and no plans for high-yield funds
  • You already track total return on every holding and understand coverage ratios
  • You only hold Tier 1-2 funds that don't exhibit material NAV erosion
