Discount factor = 1 / (1 + WACC)ⁿ. Terminal value computed using the Gordon Growth Model: TV = FCF_N × (1 + g) / (WACC − g), then discounted back to present.
| g ＼ WACC | 6.0% | 7.0% | 8.0% | 9.0% | 10.0% |

Highlighted cell is your current WACC × terminal-growth assumption. Cells beyond WACC ≤ g are undefined (Gordon Growth fails).
