Base the target on expenses, not income
Your emergency fund should cover what you must spend, not what you earn. Start with your committed monthly outflow: rent or home EMI, other loan EMIs, groceries and utilities, insurance premiums, and any non-negotiable dependent costs.
Discretionary spending can be cut during a crisis, so you do not need to fund your full lifestyle — but you do need to keep the lights on and the loans current while you recover.
Adjust the months for your risk
The number of months you should hold rises with your risk. Several factors push the target up:
- Dependents: more people relying on your income means a larger buffer.
- Income stability: freelancers and commission earners need more than salaried employees with stable jobs.
- Single vs dual income: a single-income household carries more concentration risk.
- High fixed EMIs: large committed payments make a gap more dangerous.
- Health cover: thin insurance increases the cash you may need on short notice.
Where to keep it
An emergency fund must be safe and quickly accessible — that matters more than squeezing out returns. The goal is that you can reach the money within a day or two without selling at a loss.
Common homes for it include a savings account, a sweep-in fixed deposit, or a liquid fund. Avoid tying it up in volatile assets or anything with a lock-in; the point of the fund is that it is there exactly when markets or your finances are stressed.
Build it in stages
If starting from zero, a full six-month fund can feel impossible. Build it in milestones: first one month of expenses, then three, then your full target. Automating a transfer right after payday makes it happen without willpower.
Once funded, top it up whenever you use it, and revisit the target when your expenses, dependents, or job situation change.
