$250,000 per depositor, per bank: how FDIC insurance actually works

Every US bank account at an FDIC-insured institution carries the same federal insurance promise: the Federal Deposit Insurance Corporation will make depositors whole, up to a specified limit, if the bank fails. The headline number — $250,000 — is broadly understood. The mechanics around it are not. The result is a recurring pattern where consumers either overestimate their coverage (assuming the $250,000 applies per account rather than per depositor at an institution) or underestimate it (not realizing that ownership categories stack additional coverage on top of the base limit). For balances under $250,000 at a single bank, neither misunderstanding usually matters. For balances above, the difference can be everything.

This explainer is a working reference for how FDIC insurance actually operates: the five ownership categories, the per-bank-charter rule that determines whether two accounts are “at the same bank,” the role of NCUA insurance at credit unions, the structural gap with fintech savings products that route to partner banks, and the practical playbook for a consumer with balances above $250,000.

The base rule

The FDIC insures deposits at member banks up to $250,000 per depositor, per insured bank, per ownership category. Each of the three modifiers is independently scaled.

• Per depositor means each unique individual is separately insured. A married couple has two depositors, so a joint account can be insured for $500,000 (covered below under ownership categories).
• Per insured bank means each bank charter is separately insured. Two banks that share a brand or a holding company are still separately insured if they hold separate FDIC charters; two banks that share a single FDIC charter under different brand names are insured once.
• Per ownership category means accounts in different ownership categories are separately insured up to $250,000 each.

The insurance applies to deposit accounts: checking, savings, money market deposit accounts, and certificates of deposit. It does not apply to investment products held at the bank’s brokerage arm (stocks, bonds, mutual funds, ETFs are SIPC-protected, not FDIC), to safety deposit box contents (not insured at all in most cases), or to cryptocurrency or precious metals held with the bank’s affiliated services.

The five ownership categories that stack

The FDIC defines several ownership categories that each carry their own $250,000 limit at the same bank, layered on top of each other. The major five categories most consumers encounter:

1. Single accounts — accounts held by one individual in their own name with no beneficiary. Insured for $250,000 per depositor per bank.
2. Joint accounts — accounts held by two or more individuals with equal withdrawal rights. Insured for $250,000 per co-owner per bank, so a two-person joint account is insured for $500,000, a three-person joint account for $750,000.
3. Revocable trust accounts (including Payable-on-Death / POD) — accounts naming one or more beneficiaries. Insured for $250,000 per beneficiary per owner per bank, up to five beneficiaries (for amounts above five beneficiaries, the calculation gets more complex). A single individual with three beneficiaries on a POD account is insured for $750,000 in that ownership category.
4. Irrevocable trust accounts — similar to revocable but with different mechanics; consult the FDIC EDIE estimator for specific cases.
5. Retirement accounts (IRA, certain Keogh) — insured separately from non-retirement accounts. A consumer with a $250,000 IRA at a bank and a $250,000 regular savings account at the same bank is insured for $500,000 total, because the two are in different ownership categories.

A married couple structuring their deposits maximally at a single bank could have coverage of: $250,000 individual account each (= $500,000), plus $500,000 joint account, plus several POD accounts naming beneficiaries (up to $250,000 per beneficiary per spouse), plus separate IRA accounts. The same couple could easily structure to over $1.5 million of insured coverage at a single bank without using any complicated structures, and over several million using POD accounts with multiple named beneficiaries.

The per-bank rule — what counts as “the same bank”

Two accounts are “at the same bank” for FDIC purposes if they are held at the same FDIC-insured charter, identified by a single FDIC Certificate Number. Banking brands and holding companies are separate from FDIC charters.

Several worked examples illustrate the distinction:

• Marcus and Goldman Sachs Bank: Marcus is a brand of Goldman Sachs Bank USA. A consumer with $200,000 in a Marcus HYSA and $200,000 in a Goldman Sachs Bank direct account is at one FDIC charter, so the $400,000 single-account total is only insured to $250,000.
• Ally Bank: separate FDIC charter from any parent. Accounts at Ally are independent for FDIC purposes from accounts at other banks under the Ally Financial umbrella (Ally Invest, etc., which are not bank deposits anyway).
• Chase Bank vs JPMorgan Chase: same FDIC charter for the consumer banking arm; a consumer with deposits at Chase Bank branches and at JPMorgan private bank deposit accounts is at one charter, so the $250,000 limit applies once across both.
• A small regional bank with multiple branches: same FDIC charter across all branches. Opening accounts at three different branches of the same bank does not multiply insurance.

The FDIC’s BankFind tool (FDIC.gov BankFind) reports the FDIC Certificate Number for any insured bank by name. Before assuming two accounts are at separately insured banks, verify the certificate numbers.

NCUA insurance at credit unions — the equivalent

Credit unions that are federally chartered are insured by the National Credit Union Administration (NCUA), not the FDIC. The NCUA Share Insurance Fund provides equivalent coverage: $250,000 per share owner, per insured credit union, per ownership category. The mechanics mirror FDIC almost exactly, with the same per-depositor, per-institution, per-category structure and the same backing of the full faith and credit of the US government.

State-chartered credit unions in most states are also insured by NCUA via state arrangements; a small number of state-chartered credit unions are insured by private insurance funds instead, which are not federally backed. Verify with the specific credit union — the question “is my account NCUA-insured?” should produce a yes or no, and a credit union that does not produce a clear yes is one to be cautious about.

For a US consumer choosing between an HYSA at a credit union and an HYSA at a bank, the insurance is structurally equivalent if the credit union is NCUA-insured. The credit union may offer slightly better deposit rates because of its nonprofit structure, but the deposit insurance is not a differentiator.

The fintech routing gap

A growing class of US savings products are marketed by fintech companies that are not themselves banks. The fintech operates a customer-facing app and sweeps deposits into one or more partner banks that are FDIC-insured. The marketing typically says “FDIC insured up to $X million” — and the X is much higher than $250,000 — because the fintech is routing across multiple partner banks to multiply coverage.

The mechanics matter for consumers in three specific ways:

• The insurance is on the partner bank’s deposit, not on the fintech’s product. If the fintech itself fails (operational issue, fraud, bankruptcy) and the partner banks are solvent, the deposits at the partner banks are still insured but reclaiming them may be slow and complex.
• The fintech chooses the partner banks, often dynamically. A consumer who keeps a personal account at Bank X and also uses a fintech that sweeps to Bank X among others may exceed the $250,000 limit at Bank X without realizing it — the fintech-routed deposit and the personal deposit are aggregated for FDIC purposes.
• The “up to $X million” marketing is the fintech’s aggregate across all partner banks, not the per-bank limit. For a consumer with a $50,000 fintech savings balance, the practical coverage is identical to a single FDIC bank.

The high-profile example was the Synapse / Yotta failure in 2024, where customer balances at a fintech savings product became inaccessible for an extended period despite the underlying partner-bank deposits being technically FDIC-insured. The insurance worked; the operational layer between consumer and bank did not. For most consumers, the practical implication is to prefer FDIC-insured banks directly over fintech products for the bulk of savings, and to use fintech products only for working capital balances where the convenience justifies the operational risk.

A worked example — $400,000 at a single bank

Consider Maria, who has $400,000 in cash savings at Marcus by Goldman Sachs. The structure matters for her FDIC coverage.

Structure A: single account in Maria’s name. $250,000 is insured, $150,000 is not. If Goldman Sachs Bank USA fails, Maria is a general creditor for the uninsured $150,000 and would likely recover a fraction of it from the FDIC receivership.

Structure B: $250,000 in Maria’s single account, $150,000 in a joint account with her spouse. $250,000 in the single account is insured. The joint account is insured for $250,000 per co-owner ($500,000 total), so the $150,000 joint balance is fully insured. Total insured: $400,000.

Structure C: split between two banks. Move $200,000 to Marcus and $200,000 to Ally. Both single accounts. Both fully insured because each is below the $250,000 single-account limit at separately insured banks. Total insured: $400,000. The yield differential between the two banks may be small or zero; the insurance protection is total.

Structure D: Marcus account + Treasury bills. Move $250,000 to a Marcus single account (fully insured at FDIC limit) and the remaining $150,000 to Treasury bills bought directly through TreasuryDirect or a brokerage. Treasury bills are backed by the full faith and credit of the US Treasury, which is structurally equivalent to the federal backing of the FDIC; the $150,000 in Treasuries is not subject to the FDIC limit at all because it is not a bank deposit.

For most consumers in Maria’s position, Structure C (multi-bank) or Structure D (bank + Treasury) is the practical solution. Structure B (POD or joint accounts at a single bank) works but adds the operational complexity of titling and beneficiary management. The comparison of Treasury bills, high-yield savings, and money market funds covers the per-vehicle insurance mechanics in more detail.

The FDIC’s own EDIE estimator

For any specific deposit configuration, the FDIC’s Electronic Deposit Insurance Estimator (EDIE) at edie.fdic.gov computes the exact insured and uninsured amounts based on the actual account titling. For balances near or above the limits, running EDIE before structuring deposits is the authoritative answer. Other rules-of-thumb and online calculators may approximate the calculation; only the FDIC’s own estimator is the official answer the FDIC will use in a receivership.

The structural mechanics of FDIC and NCUA insurance are stable and have been substantially unchanged since the 2010 Dodd-Frank Act permanently raised the per-depositor limit from $100,000 to $250,000.
