DEFINITION of 'Negative Float'
The period of time between when a bank customer writes a check and when it is cleared. Negative float is the difference between checks written or actual checks deposited as stated in a check register and the checks that have cleared an account according to bank records. A negative float occurs when checks are clearing faster than deposits received into the account.
BREAKING DOWN 'Negative Float'
For example, let's say Anne's balance in her check register reads $10,000 after she has written and sent out five checks of $1,000 each. However, her bank balance reads $15,000, which means that the $5,000 in checks has not been cleared by the bank yet. That $5,000 is the negative float.
