    Work out your real emergency-fund target before the next surprise expense does it for you.

    Add your essential monthly costs, choose a target number of months to cover, and see both your ideal fund size and how far away you are from it.

    Why this tool is useful
    Make the math visible before you decide what to do next.

    Emergency funds should be based on real expenses, not random round numbers.

    Coverage in months is much easier to reason about than one vague savings target.

    This helps you see the gap clearly and decide what to contribute next.
