50 singles, 20 doubles, five triples and 10 home runs produce 145 total bases. Over 200 at-bats, slugging is 0.725.

SLG = (singles + 2 × doubles + 3 × triples + 4 × home runs)/at-bats

Enter these known values and leave the other values blank.

Counts must be nonnegative whole numbers from one reporting period, with at least one at-bat.
The sum of all hit types cannot exceed at-bats. A home run is entered once in the home-run field, not again as a single.
Valid slugging ranges from 0 through 4 inclusive. It is bases per at-bat and may exceed 1; it is not a probability.

Extra-base hits contribute more than one base. One home run in one at-bat gives 4.000; zero hits gives 0.000.

Bookify accepts zero hit counts and both valid slugging endpoints, and rejects hit totals above at-bats.
