How Big Should Your Emergency Fund Really Be?

Anu, 31, Bengaluru, earns Rs. 1.8 lakh/month after tax. Her rent + EMI + essentials = Rs. 95,000. Her "emergency fund" is Rs. 40,000 in a savings account. A two-month gig gap in 2023 wiped it in three weeks. Her recovery took 11 months of cutting everything. The number you sock away before investing matters more than the return on what you invest.

By the end, you will know exactly how many months of expenses you should hold in liquid form. And where to park it so it earns while remaining accessible.

The 3 / 6 / 12 framework

Dual-income household with stable salaried jobs and rented accommodation: 3 months of monthly expenses. Single earner or single-income household: 6 months. Freelancer, consultant, business owner, or anyone with income volatility: 12 months. This is expenses, not income. Rent + EMI + groceries + utilities + school fees + insurance premiums, not discretionary spend.

Where to park it (three tiers)

Tier 1 (1 month). Savings account. Instant access. Interest 3-4%.
Tier 2 (2-3 months). Sweep-in FD or liquid mutual fund. Next-day access. Interest 6-7%.
Tier 3 (rest). Short-duration debt mutual fund or laddered FD. 3-7 day access. Interest 7-8%.

The liquidity-return trade

An emergency fund's job is to be there. A 1% higher return on Rs. 6 lakh is Rs. 6,000/year; the downside of needing it in 24 hours and not having it could be Rs. 50,000 in desperate borrowing. Optimise for speed, not yield.

Credit cards are not an emergency fund

A credit card delays an emergency by 45 days at 36-42% annualised interest if unpaid. It is leverage, not liquidity. The fund should exist separately.

Emergency fund + job change

If you change jobs, top up the fund before you let employer-provided health cover expire or the severance hits. A 2-month gap between jobs without a fund is how small emergencies become career setbacks.

Key Takeaways

3 / 6 / 12 months of expenses, depending on income stability.
Park in three tiers: 1 month savings, 2-3 months sweep/liquid, rest in short-duration debt.
Credit cards are not emergency funds. Interest dwarfs the convenience.
Emergency fund size is a decision; yield is a secondary concern.
Top up the fund between job changes, before insurance lapses or severance is spent.
