An emergency fund is money set aside for unplanned costs or a drop in income. Public guides disagree on a single "right" size — CFPB says it depends on your situation, FDIC Money Smart often discusses a small starter cushion, the Federal Reserve surveys a three-month rainy day fund, and an FDIC consumer article cites experts who generally discuss at least six months of living expenses. This page shows those published ranges with dates, then multiplies months × expenses only if you enter numbers.
Not financial advice. This page republishes what CFPB, FDIC, and the Federal Reserve have published about emergency savings, with dates. It does not tell you how many months to save, which expenses to include, or where to put money. The calculator only multiplies numbers you type in. Confirm account terms and insurance coverage with your bank or credit union.
Guides do not all use the same number. Here is what each free public source on this page actually says — quoted as ranges and research measures, not as a target we picked for you.
An emergency fund is a cash reserve specifically set aside for unplanned expenses or financial emergencies. Common examples on the CFPB guide include car repairs, home repairs, medical bills, or a loss of income. In general, emergency savings can be used for large or small unplanned bills or payments that are not part of routine monthly expenses and spending.

| Published idea | Detail | Source |
|---|---|---|
| Situation-based goal (no fixed months) | CFPB says the amount depends on your situation; think about the unexpected expenses you've had and what they cost. Even a small amount can provide some financial security. | CFPB emergency fund guide |
| Starter cushion often discussed: $500–$1,000 | FDIC Money Smart Module 5 key takeaway: setting aside $500 to $1,000 can cover many unexpected expenses. Worksheet checkboxes include $100, $250, $400, $500, $600, $750, $1,000, and Other. | FDIC Money Smart (Module 5) |
| Research threshold: about 1 month of income | CFPB's March 2022 research report groups consumers by whether they have no emergency savings, some but less than a month of income saved, or at least a month of income saved. It cites prior work on typical expense spikes / income dips of about three weeks of income and notes roughly one month of savings as an important research delineation. | CFPB Emergency Savings report (Mar. 2022) |
| Survey measure: 3 months of expenses ("rainy day" fund) | The Federal Reserve's 2025 SHED asks whether adults have set aside money for three months of expenses in an emergency savings or rainy day fund. In 2025, 55% of adults said yes (unchanged from 2024; down from 59% in 2021). | Federal Reserve SHED 2025 |
| Published "at least six months" framing | FDIC's January 2025 consumer article states: "Financial experts generally recommend that you have at least six months of living expenses in a federally insured product, such as a savings account or a certificate of deposit (CD)." FDIC also notes CDs often have an early-withdrawal penalty. | FDIC Saving for the Unexpected (Jan. 2025) |
We show each range as published. Different agencies measure different things (income vs. expenses; starter cash vs. job-loss buffer).
Formula shown: target = months × monthly expenses. Optional: months to reach goal ≈ remaining ÷ monthly deposit (if you deposit a fixed amount). This does not choose a months number for you — pick a published range above or any months you want to explore.

CFPB: set guidelines for what counts as an emergency; not every unexpected expense is a dire emergency. A reserve can help avoid relying on credit cards or loans that add interest and fees. If you spend the fund, work to build it up again.

Public sources do not agree on one number. CFPB says the amount depends on your situation. FDIC Money Smart discusses setting aside $500–$1,000 to cover many unexpected expenses. The Federal Reserve surveys whether adults have three months of expenses in a rainy day fund (55% said yes in the 2025 SHED). FDIC's January 2025 article says financial experts generally recommend at least six months of living expenses in a federally insured product. VaultRubric shows those published ranges; it does not pick one for you.
Target = months × monthly expenses (numbers you enter). Optionally, remaining = target − already saved, and months to goal ≈ remaining ÷ monthly deposit (no interest). Formula is shown on the page.
CFPB lists a bank or credit union account, a prepaid card, or cash (noting cash can be lost or stolen). FDIC discusses FDIC-insured savings accounts or CDs for emergency funds, and notes CDs may have early-withdrawal penalties and that stocks, bonds, and mutual funds are not deposit-insured.
No. We republish CFPB, FDIC, and Federal Reserve material with dates and do arithmetic on numbers you type. We do not tell you how many months to save or where to put money.
Facts and arithmetic, not financial advice. Published ranges differ by source; the calculator only multiplies numbers you enter. Confirm account terms with your bank or credit union.
