Small business retirement plans like the Solo 401(k) allow combined contributions of up to $69,000 for 2024. Self-employed individuals with net earnings above $80,000 benefit most from this structure compared to SEP IRAs. For more on this topic, see International Diversification.

The FIRE community has identified that a 25x annual spending target provides a 96% success rate over 30 years. Increasing this to 28x raises the success rate to 99.2% with minimal additional working years required. For more on this topic, see International Diversification.
