Total bases is a straightforward yet revealing statistic that shows how many bases a hitter gains from their hits.
Unlike batting average, which treats all hits the same, total bases weights extra-base hits more heavily, rewarding doubles, triples, and home runs.
By summing these weighted values, you get an immediate sense of a player’s power production.

Total Bases FAQ
What are total bases?
Total bases represent the number of bases a batter gains from hits only.
A single counts as one, a double two, a triple three, and a home run four.
How is the total bases number calculated?
You multiply doubles by two, triples by three, home runs by four, add singles, and sum the results.
Walks, hit by pitch, and errors are ignored.
Why does slugging percentage use total bases?
Slugging percentage divides total bases by at bats to express how many bases a player produces per at bat, giving a quick read on power hitting.
Do walks or stolen bases affect total bases?
No. Total bases only includes outcomes where the ball is put in play for a hit.
Walks, stolen bases, and plays reached on error do not count.
Can total bases be negative?
No. The calculation uses only non-negative hit counts, so the result is always zero or higher.
