Limitation: Educational sizing worksheet only—not insurance, credit, or financial advice.
How to Size an Emergency Fund
Use bare-bones essentials—not your full lifestyle budget—when modeling a job loss scenario.
Choose a display currency.
Separate from vacation savings
Keep emergency cash in a named bucket so lifestyle goals do not drain the buffer.
What the Emergency Fund Result Means
The primary result is the target balance. Gap can be negative when you already exceed the target. Months covered and progress need a positive essentials base or target.
Emergency Fund Examples
Six months at $3,000 essentials
Entered expenses and savings
Target amount
3,000 × 6 = 18,000; 4,500 ÷ 3,000 = 1.5.
Three-month starter target
Entered expenses and savings
Target amount
Current matches the three-month target.
Build in stages
A one-month starter fund often comes before a full 3–6 month target.
