Build and Kill Zombies Cash & Upgrade Planner

Enter the numbers from your own run — the game does not publish official cash rates, so this planner shows the math behind your estimates and suggests what to buy next.

Waves clearedAverage zombies killed per waveCash per kill (your estimate)Current cash (optional)Playstyle goal

Estimated cash earned this run3,000Total including current cash3,000

Math: 10 waves × 30 kills × 10 cash per kill. Adjust the inputs until they match your run — the game shows your own totals, not ours.

Suggested next purchases

Waves 1–10Cheap rapid damage first
Low-cost rapid weapons raise kills-per-run fastest, which is exactly what funds every later purchase.
Wave 10–25One defensive piece, then more damage
Add a single survivability piece to stop mid-wave stalls, then go back to scaling damage.
Wave 25–50Heavy single-target damage
Break the wave walls that end long runs; keep your one defense piece current.
Wave 50+Balanced record-push build
Alternate heavy damage with a second defensive piece to survive deep runs.

Assumptions behind this planner

Cash per kill is your own estimate — official rates are not published anywhere.
Wave milestones (10 / 25 / 50) come from community build tactics, not official difficulty tables.
The purchase order is a planning suggestion, not a guaranteed outcome — in-game prices and balance may differ.
Inputs are clamped to sensible ranges so typos cannot produce absurd numbers.

How to use it

From one run to a plan

Five steps from a finished wave run to your next purchase.

1. Play one run and note the numbers: waves cleared, roughly how many zombies you kill per wave, and the cash you earned.
2. Divide cash earned by total kills to get your cash-per-kill estimate, then enter all values above.
3. Read the estimated earnings, then compare the suggested purchase priority against your current build.
4. Buy the suggested upgrade in-game, run again, and update the inputs to see how your income improves.
5. Use the tier list before big purchases so your cash goes to the highest-value role first.

If something looks off

Fixes for common planning problems

Numbers don't match the game: your cash-per-kill changes with wave bands — re-estimate after each big upgrade.
Estimate feels too low: kills per wave is usually the wrong input, not cash per kill — count kills more conservatively.
Can't afford the suggested upgrade: farm a lower wave band faster, or follow the cash farming guide to raise income first.

FAQ

Calculator questions

Is the cash calculator exact?

No — it is an estimator. The game does not publish official cash rates, so you enter your own numbers and the tool shows the math with stated assumptions.

What inputs does the planner need?

Waves cleared, average kills per wave, your cash-per-kill estimate, optional current cash, and your playstyle goal (damage or survivability).

How does it pick the purchase priority?

It uses a deterministic rule table: damage goals scale cheap rapid weapons first, survivability goals add defensive pieces at the wave-10 and wave-25 milestones.
