Tabulate Area does not sum up

I am having a couple of Buffers and want to calculate the share of different lancover classes within them. Its ten meters Buffers, so every Buffer has a size of about 314m². Everything is functioning great so far, but when I Export a dbf into xl and sum up all the classes some classes are 30-40m² smaller. I calculated overlapping buffers and all the buffers are completely within my land cover subset. I already converted the Buffer and Landcover files to raster files with the same results.
Any suggestions?
