Formula
Target = monthly expenses × target months. Months to goal = ceil(remaining ÷ monthly contribution). Interest growth not modeled — see the Savings calculator if your fund earns interest.
Example
$3,000/mo expenses × 6 months = $18,000 target. With $2,500 saved and $400/mo, you reach it in ~39 months.

Frequently asked
How many months should I aim for?
3 months is a common minimum; 6 months is a stronger buffer; freelancers or single-income households often target 9–12.
Should I save or pay off debt first?
Most plans start with a small starter fund (e.g. $1,000), then attack high-APR debt, then build the full fund.
Does this include investment growth?
No — emergency funds usually sit in cash or HYSA. If yours earns meaningful interest, use the Savings calculator.
Should it cover income or expenses?
Expenses — it's about staying afloat, not replacing your salary.
