    How to Use the SWOLF Score Calculator

    The SWOLF score measures swimming efficiency by combining stroke count and time for a given distance. A lower score indicates better efficiency. Here’s how to use it:

    Calculating SWOLF

    Enter the distance swum, the time taken, and the number of strokes. The calculator provides your SWOLF score and additional metrics like stroke rate.

    Example: Distance = 50 meters, Time = 40 seconds, Strokes = 30 → SWOLF Score = 70.

    Unit Selection

    Choose between meters and yards. The calculator adjusts calculations accordingly and provides efficiency metrics for your chosen distance.

    Improve your SWOLF score with technique-focused training. Learn more about stroke efficiency with USA Swimming’s Tips for Pacing and Technique.

    SWOLF Score Calculation Formulas

    Understand the math behind SWOLF and related metrics:

    SWOLF Score Formula

    SWOLF = Time (seconds) + Stroke Count

    This combines the time taken to swim a distance with the number of strokes, reflecting efficiency.

    Stroke Rate (Strokes per Minute)

    Stroke Rate = (Stroke Count ÷ Time (seconds)) × 60

    Calculates how many strokes you take per minute, indicating your stroke tempo.

    Distance per Stroke

    Distance per Stroke = Distance ÷ Stroke Count

    Measures how far you travel per stroke, a key efficiency metric.

    Unit Conversions

    1 meter = 1.094 yards
    1 yard = 0.914 meters

    These conversions are applied when switching between metric and imperial units.

    Frequently Asked Questions

    What is a good SWOLF score?
    A good SWOLF score varies by swimmer and distance. Generally, a lower score indicates better efficiency. Elite swimmers may achieve scores below 60 for 50 meters.
    How do I improve my SWOLF score?
    Focus on stroke technique, reduce drag, and practice drills to increase distance per stroke while maintaining a steady rhythm.
    Does SWOLF vary by stroke type?
    Yes, different strokes (freestyle, backstroke, etc.) have unique stroke counts and rhythms, affecting SWOLF scores. Compare within the same stroke for consistency.
    How often should I measure my SWOLF?
    Measure SWOLF every 4-6 weeks during consistent training to track efficiency improvements across various distances.
    Is SWOLF the same in pool vs. open water?
    Pool SWOLF is typically lower due to controlled conditions and wall push-offs. Open water may increase stroke count due to currents and navigation.
