SWOLF Score (Swimming)
Calculate your SWOLF efficiency score from strokes and time per pool length, with pace per 100 m and distance per stroke, free online.
About this calculator
SWOLF = strokes per length + seconds per length. A lower score means a more efficient swim. Typical recreational swimmers score 45–60 in a 25 m pool; good club swimmers 35–45. Compare scores only at the same pool length and stroke.
