Use this planner before buying the Paragon
BTD6 only reveals the final Paragon degree after you commit the upgrade. This planner lets you test the main power sources first: cash, sacrificed tower value, pops, generated income, non-Tier-5 upgrade tiers, extra Tier 5 towers, and Geraldo Paragon Power Totems.
When the estimate can differ
Treat the result as a planning estimate. Patch changes, event rules, tower price changes, difficulty settings, discounts, and unusual game states can shift the exact number. The editable price field is there because outdated fixed-price calculators are a common reason players miss their target degree.
