Calculate a target emergency fund size from your monthly expenses and desired months of coverage.

An emergency fund's target size is a simple multiplication -- your monthly essential expenses times however many months of coverage you want -- but it's a completely different, non-growth-based question from any interest or return calculation in this category.
Enter your monthly essential expenses (rent/mortgage, utilities, groceries, insurance, minimum debt payments -- not discretionary spending) and your desired months of coverage (3-6 months is common general guidance, more if your income is less stable).
Target Emergency Fund = Monthly Essential Expenses × Months of Coverage
Use essential expenses only (housing, utilities, food, insurance, minimum debt payments), not your full discretionary spending -- an emergency fund is meant to cover necessities during a job loss or crisis, not maintain your normal full lifestyle.
The target is only as good as the monthly figure you enter. Look through three months of bank and card statements and list what you would still have to pay if your income stopped: housing, utilities, groceries, transportation, insurance premiums, minimum debt payments and any required childcare or medical costs. Leave out dining out, subscriptions you could cancel, travel and shopping. For a hypothetical household with $1,600 rent, $250 utilities, $500 groceries, $300 transportation, $200 insurance and $150 in minimum debt payments, essentials come to $3,000 a month. That gives a 6-month target of $18,000 and a 3-month target of $9,000.
A large number can feel discouraging, so many people set a first milestone of one month of essentials, then build toward the full amount. If you are also paying down high-rate debt, some people keep a small starter fund while attacking the debt, then grow the reserve; this is a personal choice, and a financial professional can help weigh it. Automatic transfers on payday, directing windfalls such as tax refunds, and pausing extra contributions once you hit the goal are all common tactics.
Recalculate whenever your rent, family size or debts change, and replenish the fund after using it. The point of the number is not perfection but a cushion that lets you handle a shock without borrowing.
3-6 months is common general guidance for stable dual-income households; single-income households, variable/freelance income, or less job security commonly warrant 6-12 months instead.
Somewhere liquid and low-risk (a high-yield savings account is common), not invested in the stock market, since you need to access it quickly without risk of loss right when you need it most.
Those are better handled with a separate sinking fund. The emergency fund is for larger shocks like job loss or major medical bills, though keeping them separate is a preference, not a rule.
Your expenses tend to rise over time, so revisit the figure every year and adjust the target upward if your essential costs have increased.
Any reserve helps. Even one month of expenses can prevent a small crisis from turning into debt, so treat the full target as a long-term goal.
