A score of 100 means exact plan execution under this model, not a universal performance grade.
Cycling Power Performance Score Estimator
The Cycling Power Performance Score Estimator combines two rider-specific comparisons: achieved power versus a target power and completed work time versus planned work time. It produces a simple score centered on 100 when both components match the rider’s own plan, with a 70% weight on the power component and 30% on completion.
This is not a standardized cycling federation score or a substitute for FTP testing. It is a transparent plan-execution metric for reviewing a workout block when you want power achievement to matter more than duration completion. Always inspect both components because a single composite number can hide why a session was above or below plan.

Power component = actual power ÷ target power × 100Completion component = completed work time ÷ planned work time × 100Performance score = 0.70 × power component + 0.30 × completion component
Where:
- Target power — planned average cycling power in watts.
- Actual power — achieved average cycling power in watts.
- Planned work time — planned duration of the scored work in minutes.
- Completed work time — actual duration completed in minutes.
Assumptions: The 70/30 weighting is a deliberate calculator convention that emphasizes power attainment. It is not a standardized race ranking or physiological index and does not adjust for normalized power, terrain, heat, or fatigue.
What the result means
The score shows how closely the workout matched the rider’s own power and completion targets under the chosen 70/30 weighting.
Use the component percentages and workout context rather than treating the composite as a standalone fitness rating.
Given:
- Target power: 250 W
- Actual power: 242 W
- Planned work: 90 min
- Completed work: 88 min
Calculation:
Power component = 242 ÷ 250 × 100 = 96.8%. Completion component = 88 ÷ 90 × 100 = 97.78%. Score = 0.70 × 96.8 + 0.30 × 97.78 = 97.09.
Result:
97.1 relative performance score.
Interpretation:
The rider completed nearly all planned time and averaged slightly under target power, producing a score just below 100.
Why does power get more weight than time?
This calculator is designed for power-focused workout review, so power achievement receives 70% of the score. If your objective is different, interpret the components separately.
Can the score be above 100?
Yes. Power or duration above plan can lift the corresponding component above 100 and therefore raise the composite score.
Should I use normalized power instead of average power?
This page is defined around the power value you enter. For variable workouts, normalized or other modeled power metrics may answer a different question, so avoid mixing metrics across comparisons.
Does 100 mean I am race-ready?
No. It only means the entered workout matched its own targets under this scoring rule.
How is this different from watts per kilogram?
This score measures target execution. Watts per kilogram normalizes power by body mass and does not include planned workout completion.
