People want a time estimate, but they are really asking about trade-offs
When someone asks how long it takes to double money, they are usually not asking for a formula only. They are asking what kind of risk, patience, and contribution discipline the goal actually demands.
The “rule” is not the plan
Shortcut rules can be useful for quick intuition, but real outcomes still depend on taxes, fees, inflation, timing, and whether the assumed return is something you can actually stay invested through.
