Key Takeaways

  • 1Classic rule: 110 minus your age = % in stocks.
  • 2Age 30: ~80% stocks. Age 60: ~50% stocks.
  • 3Risk tolerance matters more than age alone.
  • 4Rebalance annually or use target-date funds.

Asset allocation — how you split stocks, bonds, and cash — drives more of your returns than picking individual stocks.

Check net worth by age benchmarks.

Allocation by Decade

20s–30s: 80–90% stocks. 40s: 70–80%. 50s: 60–70%. 60s+: 50–60% stocks, rest bonds/cash.

Adjust for risk tolerance and retirement timeline.

Simple Implementation

Use a total stock + total bond index fund pair. Or one target-date fund.

Rebalance when allocation drifts 5%+.
