Tips from Power Users
- Verify tax rates and rules for your specific jurisdiction. Tax calculations vary significantly by country, state, and even city.
- Always include inflation in long-term projections. A return that looks great in nominal terms may be modest after adjusting for purchasing power.
- Use conservative estimates for uncertain variables. Overestimating returns or underestimating expenses leads to plans that fall short in practice.
