Wormhole rolling calculator
Pick the hole, add each jump in order, and see where the collapse risk starts. The hole's mass limits come from EVE's official data A ESI-derived / official . The margin either side is the commonly cited ±10% variance C Single-source / unverified , so treat the amber band as a real risk.
Check each ship's mass in the fitting window. A propulsion module that is switched on adds a lot of mass, so the same ship jumping "hot" (prop on) counts for much more than jumping "cold". That is how rollers control where the collapse lands.

How to read it
- Safe: total mass through is below 90% of the hole's listed mass. It cannot have collapsed yet.
- May collapse: between 90% and 110%. This jump could be the one that closes it. If a ship still needs to come home, it should not be on the far side now.
- Collapsed: above 110%. The hole is gone, and anything on the far side is stranded.
- Over the jump limit: that ship cannot pass this hole at all.
