Graveyard Keeper 2 Calculator — Free Corpse Planner

What this Graveyard Keeper 2 corpse calculator does

In GK2 a corpse has no quality score of its own: its White and Red skulls are the sum of its six organs (Skin, Bones, Skull, Heart, Brain, Guts) and its pocket items (Fat, Blood, Flesh), according to Wikily and gk2db. This calculator answers the question you face at the autopsy table: if I take these parts out and embalm, what will the body be left with?

• For burial: White skulls cap the grave’s score and each Red skull cancels one wreath of decoration (grave score = the lower of wreaths − Red and White, per Wikily and gk2db). Type those wreaths and the result line applies the formula, including a negative score. Net (White − Red) is only a hint. Full checklist: Burial prep.
• For zombies: each Red skull opens a zombie perk slot and White does nothing (Wikily, graveyardkeeper2.io). The collar line names the published cap that count fits: Bronze 0–5, Golden 0–10, Steel 0–99. It does not know which collar is in your pack. See Do white skulls affect zombies? No. The bottle each GK2 resurrection spends is Reanimation Liquid — Clay + Alcohol + Salt (2 red, 1 green, 4 blue) — and it adds no skulls. The Salt in that mix is ordinary Salt from the Crematorium. GK2 Third Eye Salt is a different potion.
• Before you cut: compare plans for free here, then confirm on the table — a failed operation can leave a permanent Surgeon’s Error (−1 White / −1 Red). The cut order is Blood and Fat first, then the Anatomy floor.

Want the background first? Read the White skull and Red skull guides, or check each organ’s values on the organs table. Which Anatomy and Alchemy tech opens autopsy and reanimation is the tech tree unlock order. Where the wikis disagree on arrival bands is corpse types. The four embalming mixes, with the other laboratory formulas, are on alchemy recipes.

How to use the calculator

The planner is a quick sandbox: it adds up the White and Red skull changes for the cuts and embalming you pick, so you can compare plans before you spend kit charges or risk a good corpse. Every value it uses is listed in the rules table below. Work through the panels from left to right:

1. Enter the starting corpse. Put the White and Red skull counts the body shows when it arrives on the autopsy table (each field accepts 0–20; the defaults are 3 White and 2 Red). Those defaults are a worked example, not a typical arrival. A higher tier carries more white and more red — see how corpse types change the starting skulls.
2. Choose a goal. Pick Burial if the body is headed for the graveyard, or Zombie if you plan to resurrect it. The goal does not change the skull math. It changes the advice line, and it warns when Surgeon’s Error or a Solution for Corpses is a bad fit for a zombie.
3. Set the wreaths on the grave you can place. The field defaults to 3: Wooden Cross I (2) plus Wooden Fence I (1). The grave-score line is the lower of (wreaths − Red) and White, and it goes negative when Red exceeds the wreaths. The collar line uses Bronze 0–5, Golden 0–10, and Steel 0–99. Example buttons do not change the wreath field, so you can try each plan against the decoration you actually have.
4. Tick the extractions you plan. Blood and Fat are marked free (no kit charge) and each remove 1 Red. Flesh removes 1 White. Bone and Skin use early-guide estimates (−1 White, and Skin also +1 Red). Skull is marked Launch estimate — pending in-game test +1 Red is a classic Graveyard Keeper pattern, not a published GK2 formula. Current wikis list six organs only (Skin, Bones, Skull, Heart, Brain, Guts), so there is no separate Dark Organ toggle.
5. Set hard organ outcomes. Brain, Heart and Guts are hard organs. Early guides describe each extraction as destroying two skull values at random, so when you tick one, its dropdown unlocks: choose −2 Red, −2 White or −1 Red −1 White to match what you saw, or to test the best and worst case. Unticked hard organs are ignored.
6. Optional: Surgeon’s Error. Tick it to apply −1 White and −1 Red. That organ slot is unusable, and the body can no longer be raised as a zombie. With the goal set to Zombie, the result shows a warning.
7. Add embalming (optional). Grades match the in-game bottles: Solution for Corpses ★/★★/★★★ is +1/+2/+3 White, and Injection for Corpses is −1/−2/−3 Red with the same White gain. Zombie mixes add Red. Each checked bottle uses one of six pocket slots; a seventh is not applied. Details are on the embalming guide.
8. Read the result. The panel shows the estimated White, Red and Net (White − Red), then the grave score under the wreaths you typed and the collar that red count fits, followed by every step applied with its change. Results update instantly as you edit.
9. Reuse the plan. Example buttons load a named scenario. Copy share link puts the current choices in the address, including the wreath count as d (?w=3&r=2&g=burial&x=blood,fat&d=3). Pin this plan freezes a copy beside the form so you can edit a second version and read the difference, including the grave-score gap under the same wreaths. Compare burial vs zombie pins the untouched 3/2 body against Blood + Fat cleanup.

How the estimate is calculated

Each selected item adds a fixed change to White and Red, so the order you tick boxes does not change the total except for the pocket cap: only the first six checked bottles, in the order they appear on the page, are applied. The step list follows extractions, then Surgeon’s Error, then embalming. Final totals are rounded and never shown below zero. For burial, a Net of 3 or more is labeled burial-friendly, 1–2 marginal, and 0 or less a weak candidate. For zombies, 2 or more Red is flagged as possibly enough for perks.

Worked example: a corpse with 3 White and 2 Red, goal Burial. Tick Blood and Fat and the result becomes 3 White, 0 Red, Net 3, burial-friendly, without touching any White. Add Flesh and you drop to 2 White and Net 2, which is why the guides suggest leaving Flesh on bodies you plan to bury. A Solution for Corpses ★ on the cleaned body (3 White, 0 Red) adds 1 White, for 4 White, 0 Red, Net 4. Open those three plans directly, scored under the default 3 wreaths: cleanup, cleanup plus Flesh, cleanup plus Solution ★. The 3/2 start is this page’s example, not a measured average corpse.

Under a 3-wreath grave (Wooden Cross I + Wooden Fence I, from the burial table), grave score is the lower of wreaths − Red and White. The untouched 3/2 body scores min(3 − 2, 3) = 1. After Blood and Fat it is 3/0 and scores 3. Solution ★ makes 4 White, but three wreaths still cap the grave at 3 — the extra White pays off only when you can place more decoration. Full walkthrough: burial prep.

What it does not model

Wikily and graveyardkeeper2.io describe skulls as carried by each organ, and the same organ comes in quality variants with different White / Red mixes. The planner uses fixed per-action deltas instead, so a specific organ on your save can differ. Surgeon’s Error is an optional toggle, not a chance roll. The grave-score and collar lines are the published formulas applied to the totals: they are not new rows in data/rules.json, which is still 0.2.0. The planner does not check Anatomy mastery, count pocket items the corpse already holds, track kit charges beyond the “free” tag, or add Green skulls from long decay. It also does not know which collar is in your pack — only which published cap the red count fits. Use it to compare plans, then confirm on the table. The autopsy guide and organs reference explain these mechanics.
