How much does a big snail add to the bioload of your tank?

My daughter has a 5 gal tank with a few fish and an apple snail. The snail has grown to be about the size of a golf ball, how much is she adding to the bioload?|||A full grown Apple Snail adds the same amount of bioload as 3 or 4 neon tetras or a single male betta and a neon tetra. Or a 16th of a small oscar's bioload lol.
