How it works
Stage-aware, not flat division
Each quarter of the lifecycle uses that creature's own stage duration before current progress and effective rate are applied.
Locate the current stage
0–25% is Hatchling, 25–50% is Juvenile, 50–75% is Sub-adult, and 75–100% is Elder.
Calculate only what remains
The tool takes the unfinished part of the current stage, then adds every following stage up to the selected target.
Apply the effective rate
Baseline time is divided by the effective rate. Enter a value that reflects your server and active bonuses.
This is a planning tool, not the game's internal timer
If the live HUD or character panel differs from this result, treat the in-game value as authoritative.
FAQ
Before using the result
Important context that keeps a planning estimate from becoming a false promise.
Are these growth times official?
No. They are community-tested planning baselines reviewed on 29 August 2026. The live build, nutrients, nesting, mutations, and server configuration can change the time you actually see.
Why does the calculator use four separate stages?
The 0–25%, 25–50%, 50–75%, and 75–100% sections do not all take the same amount of time. Calculating each section separately gives a better estimate than applying one flat minutes-per-percent value to the whole lifecycle.
Should I choose 75%, 87.5%, or 100%?
Use 75% when you only need the Adult threshold, 87.5% when planning around the Prime window, and 100% when estimating the complete Elder lifecycle.
What should I enter for effective growth rate?
Use the rate that best matches the server and active bonuses you are actually playing with. A 2x effective rate halves the baseline time, while 0.5x doubles it.
Why is Austroraptor not listed?
The currently available community page contains obvious placeholder growth figures copied from another creature. This calculator leaves Austroraptor out until a reliable stage-time set is available.
Sources and method
Clearly labeled community data
Stage baselines were checked against Evrima Quick Guide creature profiles. XGamingServer was reviewed for feature comparison, while this calculator uses its own implementation with Adult, Prime, Elder targets and a 21-creature comparison table.
