What Is an Emergency Fund?
An emergency fund is cash set aside for unexpected costs — job loss, medical bills, car repairs. Financial planners commonly recommend 3 to 6 months of essential expenses, with more for unstable income or single-income households.
The calculator converts your monthly essential expenses into a target for 3, 6, 9 or 12 months, then compares your current savings to the target to show the shortfall — or the months of runway you already have.
The Method
"Essential expenses" means rent/mortgage, utilities, food, transport, insurance and minimum debt payments — not discretionary spending.

Frequently Asked Questions
How much should my emergency fund be?
Most advisors suggest 3–6 months of essential expenses. Aim for 6 if your income is variable or you are the sole earner.
What counts as essential expenses?
Housing, utilities, food, transport, insurance and minimum debt payments — the costs you cannot avoid.
Where should I keep the fund?
In a separate, liquid account — a high-yield savings account is the common choice. Not invested in stocks.
How fast should I build it?
A steady monthly contribution works best. Use a savings or budget calculator to plan the pace.
Should I pay off debt before building an emergency fund?
Most planners build a small starter fund (1 month) first, then balance debt payoff and fund growth.
