Walks and hit-by-pitch do not count as at bats. Slugging uses total bases, not hits.

What this tool does
Free baseball batting average calculator that also computes on-base percentage (OBP), slugging percentage (SLG) and OPS from a single stat line. Batting average is hits divided by at bats, shown the way the scoreboard shows it: three decimals with no leading zero, so a .300 hitter reads .300, not 0.300. Enter at bats and either total hits or the breakdown into singles, doubles, triples and home runs, then add walks, hit by pitch and sacrifice flies. The tool sums your hits, weighs each extra-base hit into total bases for slugging, and keeps walks and hit-by-pitch out of at bats where they belong, so a patient hitter with a modest average still shows a strong on-base number. OPS is OBP plus SLG. Load an example season, copy the full stat line in one click, and share a URL that reproduces every number exactly. 100% client-side, nothing uploaded.

Real-world use cases
Settle a stat argument during the game
Someone in the group chat claims their guy is hitting .300 and another swears it is closer to .270. Punch in at bats and hits and the three-decimal answer ends the debate in seconds. Add walks and extra-base hits and you can also show why the .270 hitter with a .380 on-base and .520 slugging is actually the more productive bat, which is usually the more interesting point anyway.
Track a youth or high school player across a season
A coach or parent keeps a scorebook by hand and wants more than just average. Enter the season totals so far — at bats, the hit breakdown, walks and sac flies — and read AVG, OBP, SLG and OPS at once. Share the URL with the other parent so the running line opens exactly as you left it, no spreadsheet to maintain.
Write up a player for a blog or newsletter
You are covering a local team and want the slash line in your post. Plug in the box-score totals, copy the formatted AVG/OBP/SLG/OPS line, and paste it straight into the article. The total-bases and stat-line detail give you the supporting numbers to explain why a hitter is trending up without doing the long division by hand.
Compare two hitters on the same footing
One player hits for a high average, the other walks a ton and slugs. Run each line through the calculator and put their OPS side by side. The slash line makes the trade-off visible: batting average alone would crown the first player, but OPS often tells a different and fairer story about who helps the offense more.
Common pitfalls
Counting walks as at bats. A base on balls or hit by pitch is not an at bat, so it must stay out of the batting-average denominator. Folding walks into at bats drags the average down and is the single most common batting-average error.
Using hit count instead of total bases for slugging. Slugging weighs a double as 2 bases, a triple as 3 and a home run as 4. Dividing plain hits by at bats gives batting average again, not slugging, and undercounts every power hitter.
Forgetting sacrifice flies in the OBP denominator. Sac flies are excluded from at bats but added back into the on-base denominator. Leaving them out inflates OBP slightly, which is why a careful calculator asks for them separately.
Privacy
Every number here — batting average, on-base, slugging, OPS and total bases — is plain JavaScript that runs in your browser tab. No stat line, player name or box score ever leaves the page, and nothing you type is logged. The one caveat: the shareable URL encodes your stats in the query string, so a share link pasted into chat records those numbers in the recipient server access log. For anything you would rather keep private, use the copy button and paste the text instead of sharing the URL.
