About the Idle Progression Calculator
The Idle Progression Calculator is one of several free tools we offer for idle, incremental, and roguelike players. Whether you are optimizing your Cookie Clicker ascension strategy, planning a Universal Paperclips phase transition, or calculating time-to-target in any idle game, this calculator handles the math for you.
What this calculator handles
- Time to target — how long until you reach a specific resource amount, accounting for compound growth
- Production rate required — what CPS you need to reach a goal in a fixed window
- Growth forecast — projected total after a given time window with a growth rate
Tips for accurate results
- Use the highest realistic growth rate for your current game phase
- Account for any cap on production (some games cap per-second gains)
- For prestige-heavy games, run the calculator separately for each prestige tier
