What do I enter for upgrade price and gain?
The two numbers on the hammer upgrade button in-game: what the next tier costs and how much Appeal per click it adds. The game displays both on screen - this site uses your entered values because no public source lists the in-game hammer price ladder.
Is value per Appeal the only thing that matters?
It is the right tiebreaker between two tiers you can afford today. Price still gates you: a better value-per-Appeal tier you cannot afford yet is not a candidate, and the cheapest tier usually wins early because its relative gain is largest.
Why does the same +1 gain matter less later?
Percentages. A +1 gain on a 5 Appeal-per-click base is +20% income; the same +1 on a 50 base is +2%. Absolute gains shrink relatively as your base grows, which is why mid-game progress shifts toward multipliers (belts, VIP, limiteds) and Wins instead of raw per-click points.
Should I save for an expensive tier or keep buying cheap ones?
Banked Appeal earns nothing, so continuous buying on the best affordable value-per-Appeal usually beats saving. The exception: when the next tier is one session away and clearly outclasses everything affordable, a short save can be right - the planner's income-gain percent shows you the jump before you commit.
Do Robux Appeal packs change this math?
They replace grinding time with money instead of raising your rate. The documented packs run from +100,000 Appeal for 49 Robux to +100 million for 499 Robux, and bigger packs buy more Appeal per Robux - the table above shows the exact curve (LootWiki store table, checked October 3, 2026).
