      Formula

      Target = essential monthly expenses × months of cover
      Still to save = target − already saved
      Months to get there = still to save ÷ monthly saving, rounded up
      Cover you have now = already saved ÷ essential monthly expenses

      How to use it

      1. Add up the monthly costs you could not cut: housing, utilities, food, insurance, transport and minimum debt payments.
      2. Choose how many months you want covered.
      3. Enter what you have set aside and what you can add each month.

      How many months?

      Three to six months of essential expenses is the standard advice. Lean toward three if your household has two steady incomes and few dependents; lean toward six to twelve if you are self-employed, on commission, the only earner, or work in a field where finding a new job takes a long time.

      If the full target feels distant, start with one month or a flat $1,000 — enough to keep a car repair off a credit card — then build from there.

      Where to keep it

      Somewhere safe and quickly reachable: a high-yield savings account or money market account, separate from everyday spending. Not in stocks, where it could be down just when you need it, and not locked in a CD with a steep withdrawal penalty.

      Questions people ask

      How much should I have in an emergency fund?

      Three to six months of essential spending. With $3,500 of essentials that is $10,500 to $21,000.

      How long will it take to build?

      Needing $21,000 with $4,000 saved and $500 a month going in, 34 months. Raising the monthly amount to $750 cuts that to 23 months.

      Should I pay off debt or build an emergency fund first?

      A common approach: build a small starter fund of about one month, then attack high-interest debt, then finish the full fund. Without any buffer, the next surprise simply goes back on the card.
