About this Sugar Lump Calculator

This free Cookie Clicker Sugar Lump Calculator helps you plan your next harvest precisely. Enter the start time or current age of your lump and the tool estimates when it will mature and when it will reach the ripe window. You can tweak standard durations, add growth speed bonuses, and generate a short projection table for upcoming lumps. All calculations run locally in your browser; no data is sent anywhere.

How to Use

If you know when your current sugar lump started growing, set the Start time. Otherwise, enter the current age in hours. Adjust the Hours to mature and Hours from mature to ripe if needed, then include any Growth speed bonus from upgrades or seasonal effects. Click Calculate to get the time remaining and the exact timestamps for mature and ripe. Use Copy permalink to save or share the configuration and revisit it later.

Tips

Consider harvesting during the ripe window to maximize returns. If a speed bonus is active, the calculator reduces total time accordingly, which can align harvests with your play schedule. Projections can help you line up future lumps with unlocks and minigames. The goal is clarity and precision—no clutter, no ads, and simple controls that work on any device.
