Project prices with ( √base ± factor )² — 360° = factor 2 on the square-root scale.
√100 = 10 (square root center)
Target at 90° up: 110.25 (factor 0.5)
Standard angles — ( √N ± factor )²

Gann Square of Nine Calculator helps you project prices with ( √base ± factor )² — 360° = factor 2 on the square-root scale. It is commonly used by finance teams, founders, individual planners for gann square of nine calculator, gann square of 9 formula, gann calculator.
Formula
Price = ( √N ± factor )²
factor = (degrees ÷ 360) × 2
- **360°** → factor **2** (full rotation on the wheel)
- **180°** → factor **1**
- **90°** → factor **0.5**
- **45°** → factor **0.25**
Add the factor for resistance above a pivot low; subtract for support below a pivot high.
Example (pre-filled)
Base 100 → √100 = 10 → 180° up = (10 + 1)² = 121
