Calculate official OBP, compare actual times reaching base, and see how many future on-base events are needed for a target.
Separate official OBP events from real base-reaching notes and check the path to a target OBP.

Enter official OBP inputs first. ROE, fielder choice, and sacrifice bunts are shown as reference only.
Use remaining OBP denominator chances to estimate the minimum future times on base.
Target status
Target metNeeded future times on base
38Outs allowed and still hit target
82Future reach rate needed
31.7%Projected OBP at target pace
.362Hits, walks, and hit by pitch increase the official numerator.
Sacrifice flies lower OBP because they add an OBP chance without an on-base event.
Reached on error, fielder choice, and sacrifice bunt are useful context but excluded from official OBP.
OBP = (H + BB + HBP) / (AB + BB + HBP + SF)
Official OBP includes H, BB, HBP and SF in the denominator.
Official OBP excludes ROE, fielder choices, and sacrifice bunts.
Reference reached-base notes help coaches review pressure and contact quality.
Check that hits do not exceed at-bats before using the number for a report.
Sacrifice bunts are usually excluded from OBP, while sacrifice flies are included in the denominator.
For a target plan, enter only future OBP denominator chances, not projected sacrifice bunts or other excluded events.
Official OBP counts hits, walks, and hit by pitch in the numerator. The denominator is at-bats plus walks, hit by pitch, and sacrifice flies. Reached on error, fielder choices, and sacrifice bunts are useful notes but not part of official OBP.
Yes, a sacrifice fly is included in the OBP denominator but not in the numerator.
No. It can be tracked as an unofficial on-base event, but it is not official OBP.
Yes. Enter the remaining OBP denominator chances and the tool estimates how many times on base are needed.
