Droid Tycoon Cost, Crafting Time and ROI Guide
See the stable formulas behind droid costs, passive income, and station crafting time, then compare which variants offer the best pure credit return.
Checked across 62 craftable droids and all six variants on July 16, 2026.
The core formulas
Credit payback = cost ÷ income per second
Income efficiency = income per second ÷ cost
Break-even from craft start = craft time + credit payback
Crafting time follows one universal formula
| Variant | Default crafting time multiplier |
|---|---|
| Default | 1× |
| Gold | 4× |
| Diamond | 7× |
| Rainbow | 10× |
| Beskar | 8× |
| Galactic | 15× |
Pure credit ROI compared with Default
| Base rarity | Default | Gold | Diamond | Rainbow | Beskar | Galactic |
|---|---|---|---|---|---|---|
| Common and Rare | 100% | 50% | 50% | 66.7% | 75% | 120% |
| Epic | 100% | 50% | 50% | 66.7% | 27.2% | 17.3% |
| Legendary | 100% | 50% | 50% | 66.7% | 6% | 2.5% |
| Mythic | 100% | 50% | 50% | 33.3% | 2% | 0.94% |
So, do Rainbows suck?
Not across the board. Common through Legendary Rainbow droids repay 1.5 times slower than Default, but beat Gold and Diamond on pure credit ROI. Mythic Rainbow is the bad breakpoint at 3 times slower. High-rarity Beskar and Galactic droids are much larger pure-credit losses.
