About this tool
Work out how many months of expenses your emergency fund should hold based on job stability, dependants and cover.
An emergency fund is measured in months of essential outgo, not in a round rupee figure — and this calculator works out how many months you specifically need. It starts from the standard six-month planning baseline and adjusts it for income type, number of earners, dependants, health cover and how much of your outgo is locked into EMIs, then converts the answer into a rupee target, your current coverage and the time to close the gap at a chosen monthly contribution and liquid-fund return.

Government service, a startup job and self-employment produce genuinely different targets from the same expenses.
Committed loan instalments are part of the outgo you must keep paying with no income, so they sit inside the target.
Compounding on the parked money is included, so the time-to-goal reflects a sweep FD or liquid fund rather than a plain division.
Three to six months of essential outgo for a stable salaried earner and six to twelve months where income is variable or a single salary supports several people. Six months is the usual starting point; a self-employed earner with dependants and thin health cover should sit at the upper end.
Yes. Home, car and personal loan instalments do not pause when income stops, so add them to essential expenses before multiplying by the number of months. Discretionary spending like holidays and shopping should be left out, because you would cut those first.
Somewhere you can reach in a day or two without a capital loss — a sweep-in or flexi fixed deposit and a liquid or overnight mutual fund are the two common choices. Equity, ELSS with its three-year lock-in, and PPF are unsuitable because the money is either volatile or locked.
Usually yes, because cash earning about 6-7% loses purchasing power against inflation, so the extra safety is expensive. If your risk factors point past twelve months, the better fix is to remove the risk — buy adequate health cover, prepay a costly loan, add a second income — rather than pile up more cash. This is general information, not personalised advice.
