SWOLF Score Calculator
SWOLF is the simplest single number for swimming efficiency: add the strokes you take for one length to the seconds it takes you to swim it. Enter both plus your pool length and this calculator returns your SWOLF score and an equivalent per-25 m value so you can compare pools. Use it to track technique gains, because a falling SWOLF at the same pace means you are getting more distance from every stroke.
SWOLF (Swim Golf) adds your stroke count and your time in seconds for one pool length. Like golf, lower is better: you can lower SWOLF by swimming faster or by taking fewer, more efficient strokes. Because it combines both, it rewards true efficiency rather than just thrashing harder. Compare SWOLF at the same speed and pool length, and use the per-25 m value to compare 25 m and 50 m pools.
Frequently Asked Questions
- What is a SWOLF score?
- SWOLF (swim golf) measures swimming efficiency by adding the seconds you take to swim one pool length to the number of strokes you used. A lower SWOLF means you cover the same distance with less time and fewer strokes, signalling better technique.
- How do I calculate SWOLF?
- Count the strokes for one length and time that same length in seconds, then add the two numbers. Enter strokes and time per length here and the calculator returns your SWOLF plus a normalised per-25 m value so you can compare different pool sizes.
- What is a good SWOLF score?
- For a 25 m pool, scores roughly in the 30s indicate strong efficiency, the 40s are typical for fitness swimmers, and higher values suggest room to improve. Because SWOLF depends on height, pool length and stroke, compare it against your own past results.
