Estimated result
Your target time will appear here
Enter a target and a cash-per-second reading. Your inputs stay in this browser and are not sent to analytics.
2. Change
Test one upgrade at a time
Record the rate before and after one slot, turret or upgrade so you can see what actually changed.
3. Plan
Use the result as an estimate
Recalculate when a boost ends or your wall changes. The tool does not promise a fixed in-game payout.
Formula
How the estimate works
Effective rate = observed cash per second × the multiplier you enter. Time to target = cash still needed ÷ effective rate. Session projection = current cash + effective rate × planned seconds.
Income calculator questions
What number should I use for cash per second?
Use the cash-per-second value shown by your current base in game. Recheck it after changing a turret, slot, upgrade or temporary boost.
Does the calculator know every turret's income?
No. Reliable per-turret income and upgrade scaling are not publicly listed, so this tool uses the total rate you personally observe.
What should I enter for the multiplier?
Leave it at 1 unless you measured a current boost. The site does not assume a permanent 2x or other game bonus.
Why can the in-game result differ?
Temporary boosts, missed enemies, new upgrades, server behavior and game updates can change the rate. Treat the result as a planning estimate.
