In plain words
Three to six months of essential spending, kept in cash that can be reached at once, is the usual guide. It is a safety cushion, not money for earning returns.
Two worked examples
The common mistake
The mistake: Investing before there is a cash cushion, then having to sell at a bad moment.
What’s true: Each rung protects the one above — invest before the floor exists and one shock unwinds everything.
The floor before the roof
A common rule of thumb puts money in an order: essentials, an emergency fund, high-interest debt, then investing, then extras.
Big bills you can see coming
A sinking fund divides a known cost by the months left and sets that much aside each month, so the bill is paid before it arrives. A bill you saw coming, paid from one month's pay, feels like an emergency; spread over the months before, it is just another line.
Where you’ll meet it
- Cash loses to inflationPrices climbing while cash sits still is a pay cut nobody announces.
- Deposit insurance has a limitThe cover follows the bank, not you: the same limit applies at each bank, and only to deposits.
- When you need it decides where it sitsA fall in value only hurts if you must sell during it — the nearer the date, the less time to wait it out.
