Where to keep it
Keep your fund liquid (instant access), safe (no market risk) and separate from investments. Good options: a high-yield savings account, a liquid mutual fund, or an FD with premature-withdrawal facility.
The cushion that keeps a bad month from becoming a bad year
An emergency fund is the difference between a setback and a crisis. Lose a job, face a medical bill or a sudden repair, and a cushion of cash means you handle it without selling investments at a loss or reaching for a credit card. This emergency fund calculator turns your real monthly expenses into a clear target and shows how close you are.
It works from essentials only, the costs you cannot pause: housing, food, utilities, transport, insurance and loan payments. Multiply those by your chosen buffer, three to twelve months, and you have your target. The progress bar shows how far your current savings go, and the time estimate tells you how many months of your chosen monthly saving it takes to close the gap.
Keep the money liquid and separate so it is there when you need it and out of sight when you do not. Once your fund is solid, put new savings to work with the budget calculator, the savings goal calculator and, if you are tackling debt at the same time, the debt payoff calculator.

FAQ
Frequently asked questions
How much emergency fund do I need?
The common guidance is three to six months of essential expenses, but the right number depends on your situation. Three months suits a stable job with dual income. Six months suits a single income or a variable job. Self-employed people and those with dependents often aim for nine to twelve months. This calculator works out the target from your actual monthly essentials.
What counts as an essential expense?
Essentials are the costs you cannot easily cut: rent or home loan EMI, food and groceries, utilities, transport, insurance premiums, other loan EMIs and basic necessities. Leave out discretionary spending like dining out, subscriptions and holidays, because in an emergency you would pause those. The fund only needs to cover the must-pay items.
Where should I keep my emergency fund?
Keep it liquid, safe and separate from your investments. Good options include a high-yield savings account, a liquid mutual fund, or a fixed deposit with a premature-withdrawal facility. The goal is instant access without market risk, not maximum return. Mixing it into your investment account makes it too tempting to spend and too risky to rely on.
Should I build an emergency fund before investing?
Usually yes, at least a starter buffer. Without a cushion, one unexpected bill can force you to sell investments at a bad time or take on high-interest debt. A common approach is to build one month of expenses first, then invest while topping up the fund to the full three to six months over time.
How long will it take to build my fund?
It depends on the gap between your target and what you have, divided by how much you can save each month. Enter your monthly saving in the calculator and it estimates the number of months to reach your goal. Even a small, automatic monthly transfer adds up faster than most people expect.
