Use this calculator to determine the Diamond cost to buy the time required to finish an upgrade.

This calculator calculates the amount of Diamonds that it will take to pay for the time remaining on the upgrade. For an upgrade's Instant cost, which pays for both the time and the resources, visit the unit's individual page.

Note: The initial upgrade time is a factor in calculating the cost of finishing the upgrade later on, so it is required. Not entering it will result in an error.
