Enter a troop count — or the heal time you're staring at — and see the full bill: resources, wait, speed-ups, rubies, and the real money behind "Finish Now." Calibrate it once to your account and the numbers are exact.
Heal time and resource cost depend on your troops' HP and bonuses, so they differ per player. Open Emergency Center, set the slider to a round troop count, and copy the three numbers into the matching cards — no need to start the heal. Fields are pre-filled with the screenshot's example; replace them with yours and hit Calibrate.
Numbers calibrate to your account and save on this device. Resources are spent whether you wait or Finish Now — only the wait is skipped.
