Quick answer
12 months is double the coverage of 6 months.
That usually means a larger target and a longer timeline.
Comparing both as scenarios helps you plan.
What 6 months and 12 months mean
Both are multiples of your monthly essentials. The difference is the size of the target and the time it may take to build. Neither is universal—model both.
Target amounts (same expenses)
| Monthly essentials | 6 months target | 12 months target | Difference |
|---|---|---|---|
| $2,800 | $16,800 | $33,600 | $16,800 |
Doubling months of coverage doubles the target for the same expense base.
When a larger buffer can make sense (conceptual)
- Income is less predictable.
- High fixed housing or medical costs.
- Single income household.
- Longer job search expectations.
- Desire for more cushion during a transition.

Tradeoffs
- Longer time to build a larger target.
- May need higher monthly savings to hit a specific date.
- Opportunity cost: more cash held for liquidity instead of other goals.
- Keeping the fund accessible matters; avoid tying it up.
- Balancing buffer size with other priorities is important.
Timeline example
| Target | Target fund | Current savings | Gap | Monthly savings | Estimated months | Notes |
|---|---|---|---|---|---|---|
| 6 months | $16,800 | $3,000 | $13,800 | $500 | ≈ 27.6 | Gap ÷ monthly savings. |
| 12 months | $33,600 | $3,000 | $30,600 | $500 | ≈ 61.2 | Same savings rate, larger target. |
Timeline is an estimate and will change if contributions or expenses change.
How to model both targets in the planner
- Enter your monthly essentials and current savings.
- Save a scenario called “6 months.”
- Change the months target to 12 and save a “12 months” scenario.
- Compare shortfall and timeline; adjust contributions if needed.
Open the Emergency Fund Planner and review the timeline guide for completion date details.
