Cash Per Wave is a workshop upgrade that gives you a flat amount of cash every time you finish a wave. It sits alongside Cash Bonus as one of the two core cash upgrades, and the two multiply together, so levelling both is how you grow your economy.
Description
Cash Per Wave pays out a set amount of cash each time you complete a wave. The payout lands after the wave cooldown timer finishes and is credited before interest is calculated, so the cash you receive can immediately feed into your interest earnings for that round.
Workshop
You unlock Cash Per Wave in the workshop for 40 coins, and it becomes available together with Cash Bonus. It starts at a base value of 0 and has 149 upgrade levels, with each level adding 4 to the payout, reaching a maximum of 596. The final amount you receive per wave is this value multiplied by your Cash Bonus, so the two upgrades scale off each other.
Cost
The coin cost rises with each workshop level. The cost table below lists the price of every level up to the maximum.

Cash/Wave
A matching lab upgrade, Cash/Wave, is unlocked through Milestones at tier 1 wave 30. It has 99 levels, and each lab level increases the size of the workshop increments while also raising the maximum workshop value, letting you push the per-wave payout well beyond the base cap. The table below shows the effect of each lab level.
