IFSC Bouldering Points Calculator
Compute scores under the 25/10/-0.1 system used since 2025
The IFSC bouldering scoring system in effect since 2025 awards 25 points per top, 10 points per zone (when no top is achieved), and subtracts 0.1 point for every failed attempt before the result. This calculator runs the formula across any number of boulders and returns a total. Use it to verify athlete scores, check tie-break edge cases, or model what a result would have to be to clinch a podium.
Formula: 25 pts per top, 10 pts per zone without top, -0.1 pt per failed attempt before the result.

How the formula works
The IFSC 25/10/-0.1 scoring formula is simple in structure but adds up quickly across a round.
- Top achieved: 25 - (0.1 × failed attempts before the top). A flash (top on first try) is worth 25.0. A top in 5 attempts is worth 25 - 0.4 = 24.6.
- Zone achieved without top: 10 - (0.1 × failed attempts before the zone). A zone reached on the first attempt is worth 10.0.
- No zone, no top: 0 points.
- Total score: sum across all boulders in the round.
The penalty caps the strategic value of throwing many attempts. For elite athletes, the difference between flash and 5-attempt top is meaningful — 0.4 points can decide a podium when several climbers top all four boulders.
Worked example
Athlete A in a 4-boulder qualification round:
- Boulder 1: top in 1 attempt → 25.0 points
- Boulder 2: top in 3 attempts → 25 - 0.2 = 24.8 points
- Boulder 3: zone in 2 attempts, no top → 10 - 0.1 = 9.9 points
- Boulder 4: no zone, no top → 0 points
Total: 59.7 points.
In the calculator above, set Boulder 1 to Top with 1 attempt-to-top, Boulder 2 to Top with 3 attempts-to-top, Boulder 3 to Zone with 2 attempts-to-zone, and Boulder 4 to None. The total updates to 59.7.
What this calculator does not handle
This is a quick-reference calculator. It does not model:
- Tie-breakers — IFSC tie-breakers consult prior round rankings, then countback. The calculator does not cross-reference rounds.
- Multi-round progression — qualifying, semi-final, and final use the same formula but on different boulder sets. Run the calculator separately per round.
- Live event recalculation — for actual events, JudgeMate runs server-side scoring with all edge cases handled. This calculator is for athlete-side estimation, organizer planning, and educational purposes.
