Age-based rules of thumb exist because they capture something real about time horizon, but they're genuinely incomplete without considering your full picture. The questions that actually determine appropriate aggression level include whether you have other retirement savings already working, what your income stability looks like, whether this three thousand represents a small portion of your net worth or most of it, what other financial goals compete for resources in the next five to ten years, and critically whether you've experienced a significant market downturn with real money at stake yet. Someone with stable income, diversified retirement savings, and genuine ability to ignore a forty percent temporary drawdown can be more aggressive than age-based formulas suggest.
