Free Luck Incremental rebirth calculator. Input your stats to find the optimal rebirth timing threshold on Roblox.
About the Rebirth Calculator
The rebirth calculator is an interactive tool on this page that helps you decide when to rebirth in Luck Incremental. Rebirthing too early wastes potential multiplier growth; rebirthing too late slows your world progression. The calculator compares your current Rebirth multiplier against projected gains to recommend the optimal action.
Use the calculator UI component below this article to input your current stats. The tool accounts for base multiplier, upgrade levels, talent tree bonuses, and relic modifiers where applicable.
How Rebirth Math Works
Each rebirth resets your upgrade levels but multiplies your permanent Rebirth multiplier based on stats accumulated during the cycle. The key question is whether continuing to upgrade yields more total multiplier per minute than resetting and rebuilding with a higher base multiplier.
Early game rule of thumb: rebirth when gain exceeds 2–3x current multiplier. Mid game: 1.5–2x with talent bonuses. Endgame: calculate every rebirth individually due to prestige and Factorize interactions. Read efficient rebirth guide for the full strategy.
Calculator Tips
Update your inputs after every talent node purchase or relic pull — permanent bonuses change the optimal threshold. Before world gate pushes, rebirth aggressively to rebuild upgrade levels quickly with your higher multiplier.
Pair calculator results with early, mid, and endgame builds for context on what to upgrade after each rebirth.
