A method for ascertaining a correction value for a fuel metering of a fuel injector of an internal combustion engine, in which fuel is injected from a high pressure accumulator into a combustion chamber with the aid of the fuel injector, a value which is representative for a static flow rate through the fuel injector being ascertained by way of ascertaining, during at least one injection process of the fuel injector, a ratio of a pressure difference occurring in the high pressure accumulator as a result of the injection process and an associated duration which is characteristic for the injection process, and the correction value being ascertained on the basis of a comparison of the representative value with a comparative value.
