    • Total deposits

    $250,000 is the FDIC standard maximum deposit insurance amount, per depositor, per insured bank, per ownership category. Deposits above it are not insured. Confirm your own categories with the FDIC's EDIE tool before moving money.

    How the $250,000 Limit Works

    The Federal Deposit Insurance Corporation insures deposits at member banks up to $250,000. That limit applies per depositor, per bank, and per ownership category. Understanding all three dimensions is important once your total savings exceed the threshold. Per depositor means the limit is based on who owns the money. Per bank means the same person can have $250,000 fully insured at Bank A and another $250,000 at Bank B. Per ownership category means the limit resets for each type of account: individual, joint, certain retirement accounts, and revocable trust accounts each carry their own $250,000 cap at the same bank. For a married couple, a joint account is insured up to $500,000 at one bank. Each spouse also has a separate $250,000 limit for individual accounts at that same bank. In theory, a married couple could hold up to $1,000,000 fully insured at a single institution by combining individual and joint ownership categories.

    Splitting Across Banks and Account Types

    If you have $400,000 and hold everything in a single individual savings account at one bank, $150,000 is uninsured. The simplest fix: open an account at a second FDIC-insured bank and move the excess. Keep $250,000 or less at each bank and every dollar is covered. For larger balances, the ownership-category strategy becomes practical. At one bank, a single depositor could hold $250,000 in an individual account and up to $250,000 in a qualifying revocable trust account, insuring $500,000 total at that institution. Add a joint account with a spouse and the ceiling rises further. The calculator takes your total balance and recommends the minimum number of banks or account types needed for full coverage. It does not recommend specific banks; that choice depends on rates, convenience, and your own preferences. Its purpose is to ensure that no dollar sits above the insurance line, especially as compound interest pushes your balance past $250,000 over time.

    FDIC rules have nuances beyond this summary. For complex situations involving trusts or business accounts, consult fdic.gov or use the FDIC's own EDIE estimator tool.
