A commonly cited personal finance guideline recommends keeping enough easily accessible savings to cover 3 to 6 months of essential living expenses, as a cushion against job loss, medical emergencies, or unexpected major costs.
This calculator multiplies your monthly essential expenses (rent, utilities, groceries, insurance, minimum debt payments — the costs you can't easily cut) by 3 and by 6 to give a recommended target range for your emergency fund.
Where within that 3-to-6 month range makes sense depends on your personal risk factors — job stability, number of income sources in a household, health considerations — someone with less predictable income might reasonably target the higher end of the range.

Frequently asked questions
Should I include discretionary spending in this calculation?
No, this calculation is meant to cover essential expenses only — rent, utilities, groceries, insurance, minimum debt payments — not discretionary spending you could cut during a genuine emergency.
Is 3-6 months always the right target?
It's a widely cited general guideline; your personal target might reasonably be higher or lower depending on your specific job stability, number of income earners in your household, and other individual risk factors.
