Time is an estimate. Wave rewards, downtime and server bonuses can change your actual rate.

How to get a useful estimate

  1. Watch your coins for one full minute during normal play.
  2. Enter the difference as your coins per minute.
  3. Use the exact price shown on the upgrade you are targeting.
  4. Recheck after a major base or income upgrade.

What should I calculate first?

Compare the wait for an economy upgrade with the wait for a combat upgrade. If income pays back quickly, it can accelerate every purchase that follows. If zombies are already breaking through, stabilize your base defenses first.
