How big should your emergency fund be?
An emergency fund is cash you set aside for the things that don't warn you first: a retrenchment, a car that dies, a medical bill the scheme won't cover. It's the buffer that stops a bad month turning into debt.
The rule of thumb
Most guidance lands on 3 to 6 months of essential expenses. That's a range, not a target, and where you sit in it depends on how steady your income is.
- Two stable salaries in the house? Closer to 3 months is often enough.
- Single income, or a job that could go at short notice? Lean toward 6 months.
- Self-employed or on commission, with lumpy income? 6 months or more, because your income gaps are wider.
Base it on essentials, not your whole life
Size the fund on what you'd actually have to keep paying if your income stopped, not your normal spending. Essentials usually mean your bond or rent, food, utilities, transport, minimum debt repayments, school fees, and insurance. Restaurants and holidays come off the list. A household spending R30,000 a month might only have R20,000 of true essentials, so a 4-month fund is R80,000, not R120,000.
Where to keep it
Two things matter: you can reach it fast, and it won't have dropped in value the day you need it.
- A money-market account, notice account, or plain savings account works well. You earn some interest and can withdraw quickly.
- Skip the stock market for this money. Equities can be down 20% exactly when you're retrenched.
- Don't park it in your tax-free savings account either. If you draw it in an emergency, you lose that contribution room for good.
The interest is taxed at your marginal rate, but that's a fair price for money you can grab the moment you need it.
Build it first
An emergency fund earns its keep by being boring and safe, so it's usually the first thing to sort out, before you invest aggressively or lock money away. Some people keep a starter R15,000 to R20,000 while they clear expensive debt, then build the full buffer. The two-pot savings pot can be reached in a real emergency, but it's taxed on withdrawal and costs you retirement growth, so it's a last resort, not your buffer.
