Share insurance protects money kept at a federally insured credit union. The National Credit Union Administration, or NCUA, is the independent federal agency that provides it. The coverage comes from the National Credit Union Share Insurance Fund, which Congress created in 1970. This piece walks through what the cover includes, where the limits sit, and what the public sources leave unanswered.
What share insurance is
The Share Insurance Fund is backed by the full faith and credit of the United States government. If a federally insured credit union fails, the fund covers each member's balance dollar for dollar, up to the limit. That includes principal and dividends posted through the failure date. Historically, insured money has reached members within a few days after an insured credit union closes. MyCreditUnion.gov explains the basics.
Coverage applies to all federal credit unions and the vast majority of state-chartered ones. The word "vast" matters. Not every state-chartered credit union is federally insured, so the first check is the insurance status itself. The NCUA's coverage page is the starting point. The sources reviewed here do not lay out a step-by-step way to verify a specific institution, so that is a gap.
How the $250,000 limit works
The standard limit is $250,000 per depositor, per ownership category. The second half of that phrase does a lot of work. Accounts are sorted into categories, and coverage is figured inside each one. One person can hold money in more than one category and have each one counted on its own.
The main categories and their rules, as the coverage overview describes them:
- Individual accounts: up to $250,000 total across a person's single accounts combined.
- Joint accounts: up to $250,000 per owner, based on each owner's interest.
- Trust accounts: up to $250,000 per beneficiary, for each owner. Special rules apply to accounts over $1.25 million.
- Retirement accounts: up to $250,000 total. Traditional and Roth IRAs are added together, while Keogh accounts are insured separately. Naming beneficiaries does not raise the amount.
A concrete case: two people share a joint account holding $400,000 in equal parts. Each owner's $200,000 share sits under the limit, so the whole balance is covered on that account. Their other accounts are counted in their own categories.
What counts and what does not
Insured products include share accounts, share draft (checking) accounts, money market share accounts, and share certificates. The balance counted includes principal plus dividends earned and posted for prior periods.
Some products fall outside the cover entirely. Mutual funds, stocks, bonds, annuities, and life insurance policies are not insured by the NCUA, even if they are sold at a credit union. That is a common point of confusion, because the branch and the signage look the same. The estimator tool should not be used for those products either.
Mutual funds, stocks, bonds, annuities, and life insurance policies are not covered, even if sold at a credit union.
The fund itself is built on a legal reserve. By law, federally insured credit unions keep 1 percent of their deposits in the Share Insurance Fund, and the NCUA Board can levy a premium if necessary. The fund has been maintained at or near 1.30 percent of insured deposits.

Using the Share Insurance Estimator
The NCUA offers an online Share Insurance Estimator. It calculates coverage for personal, business, and government accounts. The practical routine is simple. List each account, note its ownership category, enter the balances, and see whether any category exceeds the limit.
The tool has limits of its own. It does not calculate irrevocable trusts or employee benefit plans. For those, the sources point people to the NCUA at 1-800-755-1030. The estimator's published computations are based on rules in effect as of May 2013, with a January 2014 release date, and the page says it is updated when rules change. The sources reviewed do not confirm whether every later change is reflected, so treat its output as an estimate and confirm anything close to a limit with the NCUA.
What the sources leave open
Several questions remain unanswered in the material reviewed. It does not explain what happens to amounts above the limit at a failed institution. It does not describe how to file a claim, or give a timeline beyond "a few days." It also references changes to the trust rules without explaining them, and it gives few details on irrevocable trusts and benefit plans.
None of this changes the core rule. Coverage is $250,000 per depositor, per ownership category, at a federally insured credit union. Questions about a particular situation belong with the NCUA directly.
