Trade tool

Compare your trade

Use the Slop Tower Defense trade calculator to compare what you give against what you receive. Build both offers with quantities, inspect range overlap and read the W/L context without treating uncertain estimates as a guaranteed win or loss.

Audited Calculator snapshot: October 8, 2026. Source observed: 2026-10-22 02:04:22 UTC. Newer source reports are pending audit; Calculator inputs and arithmetic remain unchanged. October 12 source notes below retain the previous observation.

Latest Audited snapshot: October 8, 2026. Audit/review completed: October 8, 2026. Audited source observation: October 8, 2026 (120 raw records). 65 current SUPPORTED estimates, 21 retained September 27 estimates, 45 unpriced/held entries (including historical identities). Independently VERIFIED current prices: 0. Historical snapshots: September 27 / September 19. Unspecified community value units, not Robux or cash. Demand and trend labels do not change the math. Unknown or conflicting items block the whole comparison.

Select one date for both sides. Switching dates recalculates the same names where supported; unavailable records block comparison.

      Add at least one unit to each side.

      How the result is calculated

      Each side adds the minimum and maximum listed values multiplied by quantity. The difference runs from receiving minimum minus giving maximum to receiving maximum minus giving minimum.

      If the intervals overlap, the snapshot cannot establish a clear value advantage. If one is entirely higher, the result says which side has the higher listed range. Demand, scarcity and your own preference can still affect the actual deal.

      The calculator uses the same audited snapshot as the Value List. For an individual unit’s range, demand or value history, use the Value List; this tool answers the give-vs-receive comparison.

      Try a real example

      On the September 19 historical snapshot, give two Star Fruit: 7,000–9,000. Receive one Caine: 6,000–7,000. The ranges touch at 7,000; the receiving-minus-giving difference is −3,000 to 0. There is no clear receiving-side advantage.

      In that same baseline, reduce Star Fruit to one: 3,500–4,500 against 6,000–7,000. The receiving side is higher throughout these ranges, by 1,500–3,500. This does not guarantee another player will accept.

      What this tool leaves out

      Unpriced units block the result instead of silently contributing zero. No variant multipliers are assumed: a Shiny or Void unit needs its own supported value before it can be priced here.

      This tool compares community values only. It does not log into Roblox, initiate trades or evaluate battle performance. Always inspect the actual items and quantities in the game before confirming.

      Community observed October 8, 2026; audit completed October 8. The default contains 65 current SUPPORTED estimates, 21 carried September 27 estimates and 45 unknown/held records. Independently VERIFIED current prices: 0. Historical snapshots remain selectable; this is not a live price feed. Latest source report separately observed October 22, 2026; raw changes are pending audit and never replace the default or enter arithmetic. How we handle sources, conflicts and corrections.
