An emergency fund serves as a critical financial buffer, designed to protect your income and assets during unexpected events such as job loss or medical emergencies. It is recommended to maintain a reserve covering three to six months of essential monthly expenses, which include rent, food, and debt payments, excluding discretionary spending. Many individuals mistakenly calculate their emergency fund needs based on total income rather than basic expenses, leading to insufficient reserves.

For example, an investor in Pune or Bengaluru earning ₹35,000 monthly and investing ₹5,000 in a SIP could face dire consequences without an emergency fund. If a crisis forces them to sell their SIP during a market dip, they could incur a loss of ₹11,500, negating the gains from their investments.

To build an emergency fund, a six-month target of ₹1,32,000 would require saving ₹11,000 per month, but a three-month buffer of ₹66,000 is sufficient to begin investing. A balanced approach allows individuals to allocate funds towards both their emergency savings and SIPs simultaneously, ensuring financial security while building wealth.
