Universal Tower Defense X DPS Calculator and Strategy Grid

Plan a build before you spend rerolls. Compare real UTDX unit names, stack buffs, read boss-wave thresholds, and use a bar chart that shows which tower is actually carrying the run.

TL;DR

UTDX is a high-traffic Roblox tower defense game where unit value depends on slot pressure, reroll cost, aura coverage, and boss-wave timing. This site starts with the math players need first: DPS, cost efficiency, active codes, real unit names, and wave checkpoints.

Tower DPS Calculator

Formula: base_dmg * fire_rate * (1 + level * 0.15) * product(buff_i). Add up to 6 towers, choose level 0-5, and toggle multiplicative buffs.

Real UTDX roster names sourced from BloxInformer values data; stat values here are calculator baselines and are marked as modelled until direct in-game verification expands.

How The Numbers Are Computed

DPS = base_dmg * fire_rate * (1 + level * 0.15) * product(buff_i)
buffs are multiplicative: 1.15 damage aura * 1.20 fire-rate * 1.25 crit = 1.725x
range changes uptime, not the displayed raw DPS value

I test the page by loading a known unit, applying one upgrade at a time, and checking whether the bar chart total changes by the same amount as the formula. That catches broken UI math faster than eyeballing the final total.

Beginner Route In One Screen

  1. Open with Bambee or Crow Shinobi when the banner gives either at low cost.
  2. Do not sell your first economy unit before wave 10 unless the lane is already leaking.
  3. Add one control unit before the first fast wave; Ice Empress is the cleanest budget answer.
  4. Save rerolls for banners with at least two units you would actually keep.

Source Notes

Roblox metadata comes from the official game API and page. Code freshness is cross-checked against Pro Game Guides. Unit names come from BloxInformer values data. I avoid invented anime abbreviations unless a source uses the name directly.

FAQ

What is the best UTDX unit right now?

For raw endgame damage, First Emperor (Greatest), Alpha Devil (Omega), and The Strongest in History are the safest high-value carries. For early efficiency, Bambee and Crow Shinobi give better DPS per cost.

How does the DPS calculator work?

The calculator uses base damage multiplied by fire rate, level scaling, and every selected buff multiplier. The exact formula is shown in the methodology block.

Are these Universal Tower Defense X codes real?

The codes page only lists codes that appeared in a named source and were checked for freshness on May 9, 2026. Expired codes are separated instead of mixed into the active table.
