About the Emergency Fund Calculator

This calculator sizes an emergency fund by multiplying your essential monthly expenses by the number of months of coverage you want to hold. It then subtracts what you have already saved to show the remaining gap.

Essential expenses usually means housing, utilities, food, insurance, minimum debt payments, and transportation — not discretionary spending. Three to six months is a frequently cited reference range, but the right number depends on income stability and fixed obligations.

How this works

Target = monthly expenses × months of coverage.

Assumptions

  • Uses essential monthly expenses.
  • 3–6 months is a common target; your needs may differ.

Frequently asked questions

Should I use gross or net income here?
Neither — use essential expenses. An emergency fund is meant to cover the bills you must pay if income stops, not to replace your full paycheck.
Where is an emergency fund usually kept?
Typically in a liquid, low-volatility account such as a savings or money market account, so the money is available quickly without loss of value.
Is 6 months always the right target?
No. A single-income household or variable income may call for more; a dual-income household with stable jobs may hold less.
