Bitcoin retirement
planner.

Project your retirement stack across bear, base, and bull Bitcoin scenarios. Compare a traditional-only portfolio against one with a Bitcoin allocation.

This page covers US-specific accounts and tax law. Outside the US? The priority order is the same, the account names differ (ISA in the UK, TFSA/RRSP in Canada, Super in Australia, etc.).

Sensitivity across BTC scenarios

BEAR (10%) BASE (20%) BULL (30%)

Key insight: even in the bear case (10% yearly Bitcoin growth), a small slice of Bitcoin beats a no-Bitcoin portfolio over 20-plus years. A higher-return asset, growing tax-free in a Roth, snowballs.

What this tool assumes
  • Contributions grow annually at the return rate entered.
  • Bitcoin scenarios are a hypothetical CAGR band, not a forecast.
  • Inflation is not explicitly modeled; use real (inflation-adjusted) return if you want today's dollars.

Projections are hypothetical. Past returns do not guarantee future results. Not financial advice.
