drop in the sea

Insignificant small amount

A drop in the sea is a quantity so small relative to what's needed that it makes no meaningful difference.

The image is of adding a single drop to an ocean—technically more water, but effectively nothing: The donation was generous, but against the scale of the disaster, it was a drop in the sea.

Also appears as a drop in the bucket or a drop in the ocean.
