Upkeep and Efficiency

Every Production building (Factories, Farms, and Gatherers), as well as the HQ building, have a series of Efficiency Buttons. These buttons allow you to change the Production Rate of a Production building and Research Rate in the case the HQ building. Changing the Efficiency of a building also alters the Upkeep of that building, proportional to the change made. The higher or lower the Production/Research Rate, the more or less it costs to operate that building respectively.

You can expand your Efficiency button options by researching higher and lower value in the Efficiency Tech Tree within the Auxiliary Category.

Upkeep
Upkeep represents the amount of money required to operate Player buildings; this includes harvesters and fields for Gatherers and Farms respectively. These costs can be increased or decreased by researching Unlocks on the Tech Tree (See Tech Tree) or by Events (see Events).

This includes:
 * Energy Bills
 * Maintenance Costs
 * Paying your Employees

Upkeep is calculated based on how many days a building is active for and the building cost using the following equation:

Daily Upkeep = (Building Cost * 1 / 60) / 30

Example:
 * A Carpentry Building costs $400,000 to place with a Daily Upkeep of $222.22 resulting in a Monthly Upkeep of $6,666.67.
 * Daily - (($400,000 * (1 / 60)) / 30 Days
 * Monthly - $222.22 * 30 Days

If a Building has Field or Harvesters, their Upkeep is added to the total cost of the Hub building.

Example:
 * A Water Siphon costs $125,000, and its 1 Harvester costs $50,000 to place.
 * The Water Siphon’s Daily Upkeep would be $69.44 resulting in a Monthly Upkeep of $2,083.33
 * The Harvester’s Daily Upkeep would be $27.78 resulting in a Monthly Upkeep of $833.33
 * Total Daily upkeep is $97.22 resulting in a Total Monthly Upkeep of $2916.66

When a Player enables/disables a building, it will calculate its Upkeep based on how many days it was active and subtract that value from the budget at the beginning of the next month.

Example:
 * A Player disables a Carpentry building after 15 days of being active.
 * A Carpentry Building costs $400,000 to place and the Daily Upkeep would be $222.22 resulting in a Monthly Upkeep of $6,666.67.
 * Monthly - $222.22 * 15 Days =  $3,333.3

At the beginning of every month, the total Upkeep of every active building are added together and subtracted from the Player’s Budget after all of the Income has been calculated.

Efficiency
Efficiency represents how well a building is currently operating.

By Default, a building operates at 100% Efficiency to produce its Products at their normal designed production rate (in days).

A Player can decide to reduce or increase the Efficiency of a building to produce its products slower or faster at the expense of money.

The Player can only increase or decrease the Efficiency in increments of 25% (minimum 0% / maximum 150%) after researching the related technology. Changing the Efficiency of a building will change the amount of the building's Upkeep and the amount of Products produced. Note: Values in the examples below are for clarification use only. Actual values may vary depending on the release.

Example (decrease) :
 * Player wishes to reduce the Efficiency a Food Factory producing Cheese from 100% to 50 % which will reduce the Upkeep to 60%.
 * At 100% the Food Factory will produce 2 Units of Cheese after 17.5 days and have a Daily Upkeep of 305.56 ( $5,347.22 over the total Production time or $9166.80 per Month).
 * At 50% the Food Factory will produce 1.5 Cheese after 17.5 days and have a Daily Upkeep of $210.78 ($3208.33 over the total Production time or $6323.40 per Month)

Example (increase):
 * Player wishes to reduce the Efficiency a Food Factory producing Cheese from 100% to 125 %
 * At 100% the Food Factory will produce 3 Cheese after 17.5 days and have a Daily Upkeep of 305.56 ( $5,347.22 over the total Production time or $9166.80 per Month).
 * At 125 % the Food Factory will produce 3.75 Cheese after 17.5 days and have a Daily Upkeep of $458.34 ( $8020.95 over the total Production time or $13750.20 per Month).
