Doesn't include interest — for a fund earning interest, add that in mentally as a small bonus.

The formula

Target = Monthly essential expenses × Months of coverage Months to reach goal = (Target − Current savings) ÷ Monthly contribution
Example

$3,200/month in essential expenses, targeting 3 months of coverage: target = $9,600. Starting with $1,500 and saving $400/month, the remaining $8,100 takes about 21 months to reach.

Step-by-step guide

  1. Add up your essential monthly expenses — housing, utilities, food, insurance, minimum debt payments. Leave out discretionary spending.
  2. Choose how many months of coverage you want. Three months is a common starting target; some people aim for six or more, especially with variable income.
  3. Enter what you've already saved toward this goal specifically.
  4. Enter how much you can contribute monthly to see your timeline.

Common mistakes

Basing the target on total spending instead of essential spending — an emergency fund is meant to cover necessities, not your full current lifestyle.
Investing the emergency fund in something volatile — this money is meant to be accessible quickly without risk of loss, so a high-yield savings account is more appropriate than the stock market.

Frequently asked questions

How many months of coverage do I actually need?

Three to six months is a common range. Consider more if your income is variable or a single earner supports the household, and potentially less if you have very stable dual income and strong job security.

Where should I keep an emergency fund?

Somewhere accessible without penalty or much delay — a high-yield savings account is a common choice, balancing some interest with easy access.

Should I build this before investing?

Many financial planners suggest building at least a starter emergency fund before investing heavily, so a market downturn doesn't force you to sell investments at a bad time to cover an unexpected cost.
