Step 1: Let's Learn

Read it, or press Listen and follow the words.

An emergency fund covers unexpected costs: a car repair, a medical bill, a lost job. Without one, every surprise becomes debt.

How large

The common guideline is three to six months of essential expenses, held where it can be reached quickly.

Essential, not total

Size the fund on what you must spend, not what you usually spend. In an emergency the wants stop.

Goals need a timeline

A goal is an amount and a date. Divide the amount by the months available to get the monthly target.

Check it against the budget

If the monthly target exceeds the surplus, either the date moves or the amount does. Wishing does not close the gap.

Keep it separate

Money in the spending account gets spent. A separate account makes the emergency fund harder to raid casually.

An emergency fund absorbs shocks

Its purpose is to meet an unexpected cost without borrowing. Job loss, medical costs and major repairs are the standard cases, and each is far more expensive if it has to be financed on credit.

Sizing it

A common target is three to six months of essential expenses — computed from the budget, not from income. The more variable the income, the larger the buffer typically needs to be.

Goals need an amount and a date

"Save more" cannot be planned. "Save 3,000 in 18 months" divides into 167 a month, which can go into the budget as a line. Making a goal arithmetic is what makes it actionable.

Time horizon changes the choice

Money needed next year and money needed in thirty years are usually held differently, because the tolerance for short-term fluctuation differs. The horizon is the first question, before any other.

Step 2: Try It Yourself

Tap and try it out.

Saving the same amount each month builds steadily. Change the monthly figure and see the three-month total move.
Month 1300
Month 2600
Month 3900

Month 3 has the most. It has 600 more than Month 1.

Step 3: Watch an Example

One step at a time.

Watch Kofi Size His Fund

Kofi has essential expenses of $1800 a month and can save $300 a month.

  1. Step 1

    A three-month fund needs 3 × 1800 = $5400.
