"Save three to six months of expenses" is excellent advice that is completely useless when you are choosing between the electric bill and groceries. This is the version for tight budgets: smaller targets, automatic transfers, and permission to start embarrassingly small.
Step 1: Shrink the target until it stops scaring you
Forget six months for now. Your first target is $500. That covers the car repair, the ER copay, the plumber: the small emergencies that currently go on credit cards and become big emergencies with interest. $500 is achievable, and achievable gets done.
Step 2: Find the first $100
Sell something (the garage is a savings account you forgot about), skip one subscription for two months, or redirect one week's worth of impulse spending. The first deposit matters more psychologically than mathematically: it proves the account exists and works.
Step 3: Automate an amount so small it feels silly
$25 a week. $50 a paycheck. Set the transfer for the day after payday so the money is gone before you can spend it. You will not miss $50 the way you would miss $200, and $50 a paycheck is $1,300 a year without a single heroic decision.
Step 4: Feed it windfalls first
Tax refunds, birthday money, bonuses, cash back: decide in advance that half of every windfall goes to the fund. Windfalls feel like free money, which makes them the easiest dollars you will ever save. A single $1,500 tax refund can fund the entire starter goal in one shot.
Step 5: Raise it when income rises
Got a raise? A kid aging out of daycare (congratulations, that is a raise)? Increase the automatic transfer by half the new amount and spend the other half. Lifestyle upgrades funded at 50% still feel like upgrades.
What counts as an emergency
Job loss, medical bills, urgent home or car repairs. Not: sales, vacations, holiday gifts, or a "great deal" on something you want. Write the rule on a sticky note on the fridge if you have to. And when you do use the fund, the next savings priority is refilling it before anything else.
Where to keep it
A separate high-yield savings account, ideally at a different bank from your checking so transfers take a day (friction is a feature). Not invested, not in cash at home beyond a small buffer. Boring is the point: this money's job is to be there, not to grow.
The math of starting small
$500 starter fund, then $75 a paycheck ($150/month): you hit $1,000 in under four months and $2,500 before the year is out. Run your own numbers in our emergency fund calculator to see your personal timeline. The perfect number matters less than the transfer happening this Friday.
