Workshop/Coins Per Kill
From The Tower - Idle Tower Defense Wiki and Guides
< Workshop
Coins earned from destroying enemies.
Unlocked in 
Workshop for 100 coins with Coins/Wave after Cash Bonus and Cash Per Wave. There are 149 levels with a base value of x1.00. Each level increases the base by 0.01 for a maximum value of x2.49.
Coins/Kill is multiplicative with all other bonuses that increase coins earned from kills. Example of bonuses include: Tier Bonus, Skin Bonus, Golden Bot, 
Golden Tower. These do not change the display of coin/kill. The All Coin perk will increase the displayed Coin/Kill value.
Formula[edit | edit source]
Coins/Kill (CPK) = (Workshop × CPK lab + CPK mod effect) × (1 + coin bonus enhancement) × (1 + coin bonus perk base [0.15] × perk quantity) × (trade-off perk [1.8] × (1 + trade-off lab))
- Solve the formula without rounding. Rounding will change the result from the display in game.
- Enhancement is double counted in both the tier bonus and in cpk.
- If no trade-off unlocked, replace with 1.
