FDIC Electronic Deposit Insurance Estimator (EDIE) Guide
The FDIC Electronic Deposit Insurance Estimator (EDIE) is a free, web-based calculation tool maintained by the Federal Deposit Insurance Corporation that allows depositors to determine how much of their funds at a given FDIC-insured institution are protected under federal deposit insurance rules. This guide explains what EDIE does, how its calculation logic works, and where its outputs are authoritative versus where human review is required. Understanding EDIE is particularly important for depositors whose balances approach or exceed the standard $250,000 insurance limit at a single institution (FDIC — Deposit Insurance Coverage).
Definition and scope
EDIE is a publicly accessible calculator hosted on the FDIC's official website at fdic.gov/edie. Its purpose is to apply the FDIC's ownership category rules to a depositor's self-reported account data and return an estimate of insured versus uninsured balances at a specific bank or savings association.
The tool operates within the scope of standard FDIC deposit insurance rules codified in 12 CFR Part 330 (Electronic Code of Federal Regulations, 12 CFR Part 330). It covers the primary FDIC ownership categories — single accounts, joint accounts, certain retirement accounts, revocable and irrevocable trust accounts, employee benefit plan accounts, and business/corporation accounts. The tool does not cover investment products, securities, or any instrument that falls within the scope of what FDIC does not cover, such as mutual funds, annuities, stocks, and bonds held through a bank's brokerage arm.
EDIE is institution-specific: a separate calculation must be run for each FDIC-insured bank or savings association where deposits are held, because coverage limits apply per depositor, per ownership category, per insured institution.
How it works
EDIE follows a structured, rules-based process that mirrors the methodology FDIC examiners use when calculating insurance coverage after a bank failure. The tool's logic can be understood in five sequential steps:
-
Institution identification — The user selects or enters the name of the FDIC-insured institution. EDIE cross-references this against the FDIC's BankFind database to confirm the institution carries federal deposit insurance. The FDIC BankFind tool provides independent verification of any institution's insured status.
-
Account entry — The user inputs each deposit account held at that institution, specifying the account type (checking, savings, certificate of deposit, money market deposit account, etc.) and the current balance.
-
Ownership category classification — The user assigns each account to an ownership category. This is the most consequential step: a joint account with 2 owners, for example, is treated differently from 2 separate single accounts. FDIC joint account coverage rules allow up to $250,000 per co-owner per qualifying joint account, meaning a 2-owner joint account can carry up to $500,000 in insured coverage.
-
Beneficiary and trust data — For FDIC trust account coverage calculations, EDIE prompts users to enter the number of named beneficiaries. Under rules effective April 1, 2024 (FDIC — Deposit Insurance Simplification Rule, 12 CFR Part 330), revocable trust coverage is capped at $1,250,000 per owner regardless of the number of unique beneficiaries beyond 5.
-
Output report — EDIE produces a printable summary showing total deposits entered, total insured amount, and total uninsured amount. The report is timestamped and can serve as documentation during estate planning or institutional banking reviews.
Common scenarios
Scenario A — Single depositor near the limit. A depositor holds $275,000 in a single-ownership savings account at one bank. EDIE will calculate $250,000 as insured and $25,000 as uninsured. The remedy is to open accounts at a second FDIC-insured institution or to restructure into a different ownership category.
Scenario B — Retirement accounts. FDIC retirement account coverage — covering IRAs, SEP-IRAs, and certain other self-directed retirement plans — is calculated separately from single-ownership accounts. A depositor with $250,000 in a single account and $250,000 in an IRA at the same institution holds $500,000 in fully insured funds, because these occupy two distinct ownership categories.
Scenario C — Business deposits. FDIC business account coverage for corporations, partnerships, and unincorporated associations provides $250,000 per qualifying entity per institution, separate from the owners' personal account coverage. A business owner's personal deposits and the business's deposits at the same bank are assessed independently.
Scenario D — Trust accounts with multiple beneficiaries. A revocable trust with 1 grantor and 4 named beneficiaries receives up to $1,000,000 in coverage ($250,000 × 4 beneficiaries). Adding a 5th beneficiary raises the ceiling to $1,250,000, but under the post-2024 simplification rule, adding a 6th beneficiary does not increase coverage beyond that cap.
Decision boundaries
EDIE produces estimates, not legal determinations. Three boundaries define where its outputs apply and where they do not.
Accuracy depends on user input. EDIE cannot verify account balances, beneficiary designations in legal documents, or the actual structure of trust agreements. If a user misclassifies a Totten trust as a standard savings account, the output will be incorrect. The FDIC recommends cross-referencing EDIE results with account statements and, for complex trust structures, consulting the relevant trust documents against the rules at fdic.gov/deposit.
EDIE vs. manual calculation. For straightforward accounts — standard single, joint, and IRA accounts — EDIE and a manual calculation using the FDIC deposit insurance coverage limits schedule will produce identical results. For complex arrangements involving irrevocable trusts, employee benefit plans, or multi-party business accounts, manual review against 12 CFR Part 330 may surface nuances that EDIE's simplified input fields cannot capture. The FDIC-insured account types reference covers the full taxonomy of qualifying deposit instruments.
In a failure scenario, the FDIC calculation controls. At the moment of a bank failure, the FDIC performs its own independent coverage calculation based on the institution's official deposit records, not on any EDIE output a depositor has saved. EDIE is a planning tool; the FDIC deposit payout process describes how actual insurance determinations are made by the Corporation itself, not by depositor-generated estimates.
