What is the gap between your current savings and three months of essentials?
An emergency-fund target is easier to act on when it is based on your own essential costs, not a generic dollar amount. The calculator turns a target into a monthly saving plan.
What we put into the calculator
This illustration assumes $3,500 in monthly essential expenses, a three-month target, $2,000 already saved, and 12 months to build the remaining amount. The target does not assume any investment returns.
The numbers behind the result
| Emergency fund target | $10,500 |
|---|---|
| Current savings | $2,000 |
| Current coverage | 0.6 months |
| Amount left to save | $8,500 |
| Savings timeline | 1 yr 0 mo |
What the result is really telling you
Essential expenses might include housing, groceries, utilities, insurance, medication, and minimum loan payments. Discretionary spending can be excluded if you would realistically stop it during an emergency. A one-person household and a family with variable income may choose different safety margins.
Try changing one number
Keep expenses at $3,500 and raise the target from three months to six. Next, extend the timeline from 12 months to 18. The total goal stays the same for a fixed number of months; the monthly contribution changes.

There is no single correct fund size for everyone. This model ignores account interest and inflation and does not assess the stability of income or the liquidity of existing savings.
