Mine a Planet Evolution ROI Scenario

Enter values from your own live UI. Calculations run only in this browser and do not claim to expose hidden game formulas.

Test a visible evolution milestone

This worksheet begins with the cash threshold and production rates you enter, not a built-in tier table. Mine a Planet’s official description confirms that evolutions unlock rarer ore and bigger worlds; it does not publish exact thresholds, multipliers, consumed costs, or reset rules.

The illustrative values keep the tool interactive. Replace them with a current confirmation screen and a measured route before using the recommendation.

Calculation outline

Only drones that fit into dock slots are active:

active fleet = min(fleet size, dock slots)

Current and target cash per minute apply the entered tier, fleet, dock, weather, and optional mutation multipliers to the entered base route rate. Every multiplier is a scenario assumption unless it comes from the current UI or a controlled observation.

The remaining threshold is:

remaining threshold = max(0, full threshold − current cash)

This is the amount still needed to qualify. It is not automatically the cash consumed by evolution.

For a positive production change:

break-even minutes = remaining threshold ÷ cash-per-minute uplift

Net horizon value is:

production uplift × horizon + entered side-system value − remaining threshold − entered reset penalty

Recommendation labels

• evolve_now means the entered threshold is already met and the target rate is higher. It does not waive reset warnings.
• wait means the entered target improves production and the shortfall can repay within up to twice the selected horizon.
• hard_pass means the active fleet is zero, the target rate is not higher, or the entered break-even falls outside that range.

These are deterministic branches for the worksheet, not official strategy labels.

Reset and unlock handling

Enter a direct cash-equivalent reset penalty only when the current prompt or a measured recovery plan supports it. A zero means no penalty was modeled, not that all assets are proven to persist.

Side-system value can include visible one-time rewards plus measured extra cash over the same horizon. Unknown Drone Index, alien, or UFO value is omitted and flagged. Do not double-count a listed multiplier and the measured production rate it already created.

Offline, weather, and mutation assumptions

Offline efficiency is clamped to 0 through 1 and applied only to the displayed offline rates. Weather remains a separate multiplier so a negative weather effect does not disappear inside a mutation estimate. The mutation toggle has no effect unless enabled; a multiplier of 1 means no change.

No BETA 9 or BETA 10 mutation value is presented as official.

Limits and confidence

• The target tier must be greater than the current tier.
• Fleet size and dock slots are nonnegative integers.
• Very large fleets remain limited by entered dock capacity.
• A non-positive production delta has no break-even and returns hard_pass.
• Exact cash values are scenario outputs, not predictions of server behavior.
• Re-run after a named BETA build or any visible economy change.
