For freestyle, count one arm cycle after both arms have completed a stroke. Keep the same counting convention for every comparison.

Compare SWOLF only across similar repeats for the same swimmer, stroke, effort, pool, and arm-cycle counting convention. The pool-length-per-cycle value includes the push-off and glide. A lower score is not automatically better if it comes from overgliding or a slower turn.
Calculate SWOLF, cycle rate, pool length per arm cycle, and pace from one pool length. Use SWOLF longitudinally for the same swimmer, stroke, effort, and pool rather than as a universal skill rating.
SWOLF adds the seconds for one pool length to the arm-cycle count for that length, then reports a whole-number score. It is a compact way to track the balance between swimming speed and stroke economy under comparable conditions.
Select the actual pool length, then enter the time and arm-cycle count for one length. For freestyle, one cycle is complete after both arms have completed a stroke. The calculator also shows cycle rate, pool length per cycle, and pace per 100 so you can see what changed behind the combined score.
A lower SWOLF can mean faster swimming, fewer arm cycles, or both, but it is not a universal skill grade. Compare the same swimmer, stroke, pool length, effort, counting convention, and similar push-off conditions. A 25-yard score should not be compared directly with a 25-meter or 50-meter score.
Repeat a short controlled set and look for the ability to hold pace without a rising cycle count. Compare the underlying time and cycle count when either drifts. Pair SWOLF with video, coach feedback, or drill outcomes instead of treating one number as a complete efficiency diagnosis.
SWOLF equals seconds for one pool length plus the arm-cycle count for that same length, rounded to the nearest whole score. A 25-second length with 15 arm cycles gives a score of 40.
There is no universal good score. A useful result is a repeatable personal trend under similar conditions, without lowering the cycle count by gliding so long that pace deteriorates.
Do not compare the raw scores directly. Pool length changes both time and stroke count. Keep separate baselines for 25-yard, 25-meter, and 50-meter pools.
