Before you accept a trade in Slop Tower Defense, add both sides to the calculator below. It uses the same official values as our value list and tells you whether the offer is a win, fair or a loss.
Slop Tower Defense Trade Calculator (November 2026)
Values checked November 9, 2026 · 131 units available in the calculator.
How to Use the Calculator
- Type a unit name in Your offer and pick it from the list; add every unit you would give, with quantities.
- Do the same in Their offer for everything you would receive.
- Read the verdict: the calculator compares the middle of each value range and shows the gap as a percentage.
- Check the demand column before you accept: a fair total with low-demand units can still be hard to resell.
How a Trade Is Judged
Each unit counts at the middle of its range (a unit listed as 350–400 counts as 375; a 1,000+ unit counts as 1,000). If what you receive is within 10% of what you give, the trade is fair. More than 10% above is a win; more than 10% below is a loss. Units marked Owner's choice have no price and are left out of the totals.

When the Calculator Is Not Enough
- Overpay for demand: players often add a little extra to get a 9/10 or 10/10 unit, so a small loss on paper can be fine.
- Ask before trading Owner's choice units: there is no public number, so agree on a price first.
- Re-check after updates: new banners can move values within hours of release.
Trading Tips That Keep Your Inventory Safe
- Check this page on the day you trade. Values here change when the list changes, sometimes several times a week.
- Prefer liquid units. Two high-demand towers are often easier to move than one rarer unit nobody is asking for.
- Count combat value separately. Strong raid heroes can be farmed, which keeps their trade value low despite huge damage.
- Never accept a trade you cannot undo without checking both totals in the calculator first.
