About this converter
Crazy Earl Black Market upgrades in Borderlands 2 cost eridium per rank on one shared ladder. Rank 1 White costs 4 across backpack, bank, ammo, grenade and launcher tracks. Tier 2 Green costs 8, Tier 3 Blue costs 12, Tier 4 Purple costs 16, and Tier 5 Orange costs 20. Patches extended the ladder: Tier 6 Pink costs 50 and Tier 7 Pink costs 100 for ammo, while storage alone reaches Rank 8 Cyan at 150 and Rank 9 Cyan at 200. Ammo maxes at Tier 7, so 150 and 200 belong to backpack and bank only. Buying everything costs 2,590 eridium. Every figure here is the Black Market menu tag from Borderlands Wiki tables.
How to use it
Pick two entries and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. Try 1 Backpack Rank 9 against 1 Rank 1 to see the full ladder span. The ratio line prints how many times pricier one tier is.
Ranks 6 and 7 need 2013 patches 1.4 and 1.6, flagged per row. Cash SDU data lives on a separate page, so only eridium Black Market tags sit here.
