Emergency fund: what, why, how much to save and where?

An emergency fund is money kept aside for usage in a sudden or unplanned expenditure or contingency. This money is needed to be available for immediate use in emergencies. Without this safety net in place, people will have to run around for money, depend on a loan or use a credit card at high interest rates.

An emergency fund is a part of everything you need to do before investing in financial goals. Read more here:As someone who has heard about goal-based investing, how do I get started?

Why is this needed

An emergency fund allows you to pay for:

  • Medical emergency
  • Vehicle accidents
  • Sudden repairs/theft
  • Job loss
  • Illness
  • Murphy’s Law: “what can go wrong will eventually go wrong.”

An emergency fund prevents the requirement of new debt: both personal loans and worse credit cards have high interest rates. If you already have loans, having an emergency will severely strain the monthly budget. People who earn and save well sometimes take their good fortune for granted and ignore having an adequate emergency fund. It is one of the axioms of personal finance?.

What is a part of an emergency fund

First, know your monthly expenses (not income) that includes mandatory items like

  • Food, utilities (electricity, mobile, internet), basic day-to-day expenses
  • School fees and related costs for children
  • Transportation costs: fuel, maintenance, ride-sharing etc
  • Housing: rent / EMI


  • Known recurring items like insurance premium, building maintenance etc. are saved via sinking fund: see this detailed post on that topic
  • An emergency fund is an insurance policy and not fun money. Avoid spending the emergency fund on non-emergency or incidental items like gifts, trips and white goods. These can be planned via budgeting.

How much to save

How much to keep in Emergency fund

Emergency fund estimation varies between people:

  • Those who have faced an emergency overestimate the need
  • Those who have not yet (god-forbid) underestimate the need and try to maximize returns for this money

Since a middle ground is needed, the standard recommendation is six times (6x) expenses calculated in the previous step:

  • 3x is minimum
  • 6x is normal
  • 12x is recommended in high-risk scenarios (global pandemic, recession, job uncertainty, high medical risk - diabetes, high BP etc.)

Since monthly surplus = income in hand - mandatory expenses, aggressively start saving most of the surplus to build up the emergency fund until at least 3x is saved. Do not invest in long term (>5 years) goals until at least 6x is saved.

When an emergency fund is:

  • Less than 3x: save entire monthly surplus after expenses and EMI
  • More than 3x and <6x: divert half the surplus to high-interest debt like credit cards and rest to the emergency fund
  • More than 6x and <12x: divert most of the surplus to high-interest debt like credit cards and the rest to the emergency fund. If credit card debt is not there, then some surplus can be diverted to short term goals (<5 years away)

Divert all bonuses, gifts etc., into building your emergency fund until you reach at least 6x. If your spouse does not have any income, please consider a slightly higher allocation to your emergency fund.

You can consider a psychological hack keeping one year of children’s school fees in a separate bank account as FD. This FD will give you peace of mind that your children’s schooling will not be interrupted due to any emergency.

Important: refill the emergency fund if you use it back to the original level. Review the requirement of 6-12x every time things change: job, family situation etc., to ensure you have adequate coverage.

Caveat: for people with large liquid portfolios (in stock/debt MF), it makes little sense to exceed 12x as the emergency fund. Since then, you have been tying up too much capital that can be used for long term goals.

Where to save

The emergency fund needs to be liquid, i.e. immediately available. Apart from household cash, bank accounts offer the next best place, followed by liquid mutual funds. Do not chase returns here and lock up this money in a way it is not available.

For banks, you can go with large banks like SBI, HDFC or ICICI (due to their SIFI status) and look for banks that offer sweep FD. If your bank does not provide sweep FD, it is okay - keep some money in a savings account and some in FD. Make this a joint account with all adult family members and have multiple debit cards. At all times, look for good ATM coverage for your bank and have Netbanking via apps set up on your phone. Avoid banks that have been in the news lately for issues with their operations or have a recurring history of trouble.

After choosing a bank account, liquid mutual funds can be used (choose those liquid MF which invest in 91day T-Bills and cash only). If you cannot determine which funds have this feature, please stick to banks.

A high limit credit card can be used as a part of an emergency fund if you have the money to pay it off and use it in an emergency. However, sometimes hospitals or medical stores may not accept credit cards, so this should not be your first choice.

Do not keep family gold, stock/equity MF etc., as an emergency fund - these are not liquid and can lead to losses if sold in a down market. These are for long term emergencies like medical treatment etc., where everything needs to be spent.

Many people choose housing loans or overdraft accounts like SBI Maxgain etc., for an emergency fund. However, please don’t do this since the lender may change withdrawal terms, or it is difficult to take out the money in an emergency.

Ultimately it would help if you wished that you never have to use your emergency fund but will be relieved to know it is there.
