Month targets trade safety for opportunity cost: more months means more cash sitting for shocks; fewer months means more room for debt payoff or other goals. Dual-income stability, self-employment, and dependents change the math people prefer.
Common teaching benchmarks
- 3 months: a shorter runway many people use as a first milestone
- 6 months: a widely cited middle target for essentials
- 9–12 months: longer buffers some households choose when income is variable
Nestfigure does not rank these as better or worse—only multiplies your numbers.
