Emergency Fund Calculator
Work out how big your emergency fund should be and how long it will take to build. Enter your essential monthly expenses, how many months of coverage you want, and what you have saved so far — the calculator shows your target and the monthly amount needed to reach it.
A cash reserve for job loss, medical bills, or an urgent repair is the foundation of a financial plan. Most guidance points to three to six months of essential expenses; this tool turns that rule of thumb into a concrete number and a savings timeline.

Calculation Formulas
Your goal is a multiple of the monthly costs you would still owe if your income stopped. Multiplying essential expenses by the number of months you want covered gives the total reserve to aim for.
Example:
$3,500 of essential expenses × 6 months = $21,000 target emergency fund.
Subtract what you have already set aside from the target. If you are past the target, the amount needed is zero.
Spreading the remaining amount evenly over your chosen timeframe gives the amount to set aside each month.

Frequently Asked Questions
How much should I have in an emergency fund?
A widely used guideline is three to six months of essential living expenses. Lean toward six months (or more) if your income is variable, you are self-employed, or you are the sole earner; three months can be enough with stable dual incomes and low fixed costs.
What counts as an essential monthly expense?
Include only the costs you would still have to pay if your income stopped: housing, utilities, groceries, insurance premiums, transportation, and minimum debt payments. Leave out discretionary spending like dining out, subscriptions, and travel — that is what an emergency budget cuts.
Where should I keep my emergency fund?
Keep it somewhere safe and liquid — typically a high-yield savings account or money market account — so it holds its value and you can access it within a day or two. An emergency fund is not an investment; the goal is availability, not return.
Should I build an emergency fund or pay off debt first?
A common approach is to save a small starter fund (around one month of expenses) first, then focus on high-interest debt, then finish building the full three-to-six-month reserve. A starter buffer keeps a surprise expense from pushing you back onto the credit cards you are trying to clear.
