How Much Should You Keep in an Emergency Fund?

Start with an essential monthly budget

Use recent statements and bills. Include obligations that would continue during an income interruption. Reduce discretionary spending only where you could realistically do so; do not assume every cost disappears when work stops.

Here is an illustrative household budget, not an estimate of typical U.S. spending:

Check for expenses that could increase during a disruption, such as replacement health coverage or transport for a job search. Also identify annual bills separately. A predictable annual bill needs its own saving plan; counting the same dollars as both that bill's reserve and emergency savings overstates your protection.

Choose a coverage scenario

Multiply essential monthly expenses by the number of months you want to cover. These three scenarios are planning illustrations, not universal targets or a validated risk score:

The right comparison is between a scenario and your actual vulnerabilities. A household with two incomes can still face a shared shock if both people work for the same employer or industry.

Use these questions to choose a starting scenario:

If several answers point toward a longer or more expensive disruption, compare a larger reserve. If the larger number feels unreachable today, choose an interim milestone rather than treating the whole exercise as a failure.

• Income: How variable is it, and how long could replacement work take?
• Dependents: Who relies on your income, and which care costs continue?
• Obligations: How much can realistically be reduced or delayed without serious consequences?
• Backup: Is any expected help dependable, timely, and available during the same emergency?
• Specific risks: Could a repair or deductible occur alongside an income interruption?

Add specific reserves without counting costs twice

A useful worksheet is:

Target = essential monthly expenses × chosen coverage months + additional reserve for risks not already covered.

Then:

Funding gap = target − existing eligible emergency savings, with a minimum gap of zero.

In the three-month example, the target is $9,000. If $2,000 is already available solely for emergencies and you add no separate reserve, the gap is $7,000.

An additional deductible reserve may make sense if you want to cover that bill while preserving the full income-replacement buffer. Do not automatically add every possible expense: first decide whether the monthly allowance already covers it, whether another fund pays for it, and whether the risks could realistically overlap.

Count only money you can use for this purpose

For this worksheet, count cash you can access and have actually reserved for emergencies. Exclude the next rent payment, money owed for taxes, and a vacation fund unless you deliberately reassign it. An unused credit limit is borrowing capacity, not saved cash.

For a bank account, confirm deposit protection and withdrawal arrangements. If money is held through a nonbank app, check the bank and pass-through conditions instead of relying on the app's branding. FDIC third-party banking guidance

Balance resilience against other priorities

A larger cash reserve leaves less money available for other goals. A smaller one leaves less room for disruption. Compare those costs explicitly rather than assuming more cash is always better.

If you have expensive debt, keep required payments and essential bills in the plan. Decide how much initial cash would reduce the likelihood of immediately borrowing again, then compare further saving with additional debt repayment. This is a sequencing judgment; this worksheet does not optimize debt costs or prescribe a universal cash-before-debt amount.

Avoid counting interest you have not yet earned as part of today's protection. With a $7,000 gap over 24 months, a zero-interest plan requires $291.67 per month, rounded upward to cents. Interest could reduce the required contribution, but your fund should remain useful if rates fall.

Use the savings goal calculator to translate your chosen target into contributions. Revisit the target after a move, a change in dependents, a new income pattern, or a substantial withdrawal. The target should describe the household you have now.
