Team sports & scoring
Standings, scoring, tournament formats and the fixture arithmetic of a league season. 24 tools, including At-bats per home run (AB/HR) calculator, Basketball rebound percentage (TRB%) calculator, Batting average calculator and Bowling score calculator. All free, with no account and nothing to install.
At-bats per home run (AB/HR) calculatorAt-bats per home run shows how often a hitter goes deep: AB/HR = at-bats ÷ home runs. A lower number means more frequent power — elite sluggers sit around one homer every 10–15 at-bats.Basketball rebound percentage (TRB%) calculatorEstimate the percentage of available rebounds a player grabbed while on the court (TRB%).Batting average calculatorCompute a baseball or softball batting average from hits and at-bats.Bowling score calculatorA full ten-pin bowling scorecard you fill in ball by ball. Tap how many pins fell on each throw and it applies the real rules — a strike scores 10 plus your next two balls, a spare 10 plus your next ball, and the 10th frame allows three throws — showing the frame-by-frame grid with X, / and running totals, plus undo and example games from a perfect 300 to a beginner card.Effective field goal percentage (eFG%) calculatorEffective field goal percentage adjusts the standard FG% to credit three-pointers with the extra point they are worth: eFG% = (FGM + 0.5·3PM) ÷ FGA × 100. It gives a fairer picture of a shooter's efficiency than raw field goal percentage.ERA (earned run average) calculatorEarned run average is the classic pitching stat: the earned runs a pitcher allows per nine innings. ERA = (earned runs × 9) ÷ innings pitched. Innings use the .1 = ⅓, .2 = ⅔ notation, so 180.2 means 180 and two-thirds innings.Field goal percentage (FG%) calculatorField goal percentage is the share of shots a player makes: FG% = field goals made ÷ field goals attempted × 100. It is the most basic measure of shooting accuracy in basketball, though it treats two- and three-pointers alike.FIP (Fielding Independent Pitching) calculatorFIP estimates a pitcher's run prevention using only the outcomes they control — home runs, walks, hit-by-pitches and strikeouts — scaled to look like ERA: FIP = ((13·HR) + (3·(BB + HBP)) − (2·K)) ÷ IP + constant. The league constant (default 3.10) sets FIP to the same scale as league ERA. Innings use the .1 = ⅓, .2 = ⅔ notation.Golf Handicap Calculator (WHS)Turn up to 20 scores into a World Handicap System Handicap Index and Course Handicap, with every Score Differential and the official Table 5.2a shown.On-Base Percentage Calculator (OBP)Compute a baseball slash line — OBP, AVG, SLG, OPS and OPS+ — from a batting line, with the formulas and MLB benchmarks to grade the result.OPS (on-base plus slugging) calculatorOPS combines the two halves of hitting — getting on base and hitting for power — into one number: OPS = OBP + SLG. On-base percentage = (H + BB + HBP) ÷ (AB + BB + HBP + SF); slugging = (1B + 2·2B + 3·3B + 4·HR) ÷ AB, with singles = H − 2B − 3B − HR. It is the fastest all-round gauge of an offensive player.Rugby Points Calculator (union and league)Score a match in either code: union counts a try 5 and a penalty 3, league counts 4 and 2 with a one-point drop goal. Running totals, margin and the same actions scored both ways.Basketball shooting percentage calculatorCompute a shooting percentage from shots made and shots attempted.Sleeping Bag Temperature Rating GuideTranslate a printed bag rating into a realistic comfort temperature, adjusting for sleeper, pad R-value and conditions.Slugging percentage (SLG) calculatorSlugging percentage measures a hitter's power by total bases per at-bat: SLG = (1B + 2·2B + 3·3B + 4·HR) ÷ AB. Unlike batting average, it weights extra-base hits, so a slugger who hits doubles and homers scores far higher than a singles hitter.Soccer xG (Expected Goals) CalculatorEstimate the expected-goals value of a shot from its distance, angle, body part and game situation.Strikeout-to-walk ratio (K/BB) calculatorThe strikeout-to-walk ratio gauges a pitcher's command: K/BB = strikeouts ÷ walks. Higher is better — elite pitchers exceed 4.0, while a ratio near 1.0 signals control problems. It is independent of innings, so it compares starters and relievers alike.Tennis score trackerA live tennis scoreboard that keeps the whole match for you. Set the player names, best-of-3 or best-of-5, advantage or no-ad games and how the final set is decided — 7-point tiebreak, 10-point match tiebreak or advantage set — then just add points. It counts 0/15/30/40, deuce and advantage, games won by two, tiebreaks first to seven by two, sets and the match, showing the scoreboard, the current server and an undo button.Total bases (TB) calculatorTotal bases counts every base a hitter earns from hits, weighting each by its value: TB = 1B + 2·2B + 3·3B + 4·HR. Add at-bats and it also returns the slugging percentage (TB ÷ AB).True shooting percentage (TS%) calculatorTrue shooting percentage measures scoring efficiency across all shot types — field goals, three-pointers and free throws — at once: TS% = points ÷ (2·(FGA + 0.44·FTA)) × 100. The 0.44 factor approximates how many possessions free throws consume.Usage rate (USG%) calculatorUsage rate estimates the share of a team's offensive possessions a player uses while on the floor, through shots, free throws and turnovers: USG% = 100·((FGA + 0.44·FTA + TOV)·(Team MP ÷ 5)) ÷ (MP·(Team FGA + 0.44·Team FTA + Team TOV)). Team minutes default to 240 (5 players × 48 minutes).WAR (Wins Above Replacement) calculator — simplifiedA transparent, educational estimate of Wins Above Replacement. For a position player it builds batting runs from a wOBA-style comparison of the hitter's OBP/SLG to the league, adds baserunning and a positional adjustment, then converts runs above replacement to wins (÷ runs per win, default 10). For a pitcher it works from ERA versus the league. It is a teaching model, not official fWAR or bWAR.WHIP (walks + hits per inning pitched) calculatorWHIP measures how many baserunners a pitcher allows per inning via walks and hits: WHIP = (hits + walks) ÷ innings pitched. Lower is better — an elite WHIP is under 1.00. Innings use the .1 = ⅓, .2 = ⅔ notation.Workout Plan GeneratorBuilds a weekly split from a real exercise library filtered by the equipment you actually have, with sets, reps and rest driven by the goal — heavy and low-rep for strength, lighter and high-rep for endurance. A stated limitation such as 'bad knees' genuinely removes jumps, deep squats and lunges. A curated builder, not a model, and general fitness information rather than medical advice.
