Most personal finance advice says "3–6 months of expenses." For AI training contractors, the floor should be 6 months and the right number is often higher. Here's the math.
Why contractors need bigger buffers
Three reasons:
- Income variability. Bad months happen — task pools dry up, programs end, account suspensions take time to resolve.
- Tax obligations are deferred. US, UK, India all have quarterly tax requirements. Salaried workers have it withheld; you have to plan for it.
- No paid sick days. Health emergencies = zero income while you recover.
The right size
Three tiers based on situation:
- Side-hustle (day job covers expenses): 3 months of contracting income. Buffer for tax obligations and bad-month resilience.
- Full-time contractor with stable platform: 6 months of total expenses.
- Full-time contractor without stable secondary platform: 9–12 months of total expenses.
"Total expenses" includes rent/mortgage, food, utilities, insurance, debt payments, family obligations, projected tax liability — everything you'd need to cover if income went to zero for the period.
Where to park it
US contractors:
- High-yield savings (Marcus, Ally, Discover, Wealthfront): ~4–5% APY, FDIC-insured, instant access.
- Treasury bills (TreasuryDirect, brokerage): Similar yield, tax-free at state level.
- Short-term Treasury ETFs (BIL, SGOV): Easy to manage in brokerage account.
Indian contractors:
- Liquid mutual funds: ~7% return, 1–2 day liquidity.
- Sweep FDs: Auto-converts savings above threshold to FD, returns ~6%.
- Short-term debt funds: Slightly higher returns, slightly less liquid.
UK contractors:
- Premium Bonds or easy-access ISAs: Tax-free, accessible.
- NS&I Direct Saver: Government-backed.
What not to do
- Stocks/equity for emergency money. Bad year = bad year for both your income and your "emergency fund."
- Crypto for emergency money. Volatility undermines the purpose.
- Real estate as buffer. Illiquid; can't access in 48 hours.
- Crypto-yield platforms. Counterparty risk; emergency = bad time for any of these to default.
When you can stop adding
Once you hit your target months, redirect new contributions to longer-term investments. Don't keep growing the emergency fund indefinitely — past 12 months it's an inefficient deployment of capital.
Bottom line
AI training contractors should keep 6 months minimum, often 9–12 months, in liquid HYSA / liquid mutual funds / T-bills depending on country. Build it before any longer-term investing. Once at target, redirect future cashflow to retirement accounts and equity allocation.
