The short answer
Target one month of essential spending first, then three to six months. Keep it in a separate high-yield savings account with instant access, and automate a transfer the day after payday.
An emergency fund is not an investment. Its only jobs are being there and being boring.
Step by step
- Add up essential monthly spending: housing, food, utilities, transport, insurance, minimum debt payments.
- Set milestone one at $1,000 or one month, whichever is smaller.
- Open a separate high-yield savings account so the money is not spendable by accident.
- Automate a transfer for the day after payday, even if it is small.
- Divert windfalls — tax refunds, bonuses, refunds — straight into it.
- Raise the target to 3 months (stable job) or 6 months (variable income) once milestone one is done.
- Refill it immediately after any use, before resuming other goals.

Common questions
Emergency fund or pay off debt first?
Build one small buffer, then attack high-interest debt, then finish the fund.
Should I invest it?
No. It needs to be worth exactly what you deposited on the worst day of the year.
What counts as an emergency?
Unexpected, necessary and urgent. Two out of three is not enough.
