The Last Caretaker Human Calculator (Lazarus Rack)

Pick a profession to get its food and memory targets, check a food mix against the Lazarus Rack minimums (30 cm, 20 kg, 10 years), or see which humans your food stock can already grow.

Data baseline: 2025 food screens, with some Update 5.5 checks.

Human Calculator: Start From a Profession

Choose a profession and your highest food tier: you get the fewest food items that meet its physical requirements, the memory targets it still needs, and the other professions the same human could turn out as.

Data Status

Food attributes reviewed 2026-10-05.

Game version: Food and unlock screens: November 2025; High-Fat, Mitochondrial Surge and rack estimates also have post-Update 5.5 screens. Immune Boost values disagree; 12 ingredient recipes match the wiki and game 0.8.5 data. Nanite Infusion recipes disagree.

How to Use the Human Calculator

  1. Pick what you want at the top: Grow a profession, Check my food, or What can my food grow?
  2. Grow a profession: choose the profession and the highest food tier you can make. Load the food it lists, raise the memory values it names, and keep below the numbers it warns about so the human does not turn out as another profession.
  3. Check my food: select a food and use the add or remove buttons to adjust its quantity, then compare the height, weight and life expectancy totals with the rack minimums. Read Professions These Foods Meet: every profession whose food requirements your total meets, with the memory targets it still needs. Fewer matches leave less room for the human to turn out as another profession.
  4. What can my food grow? Enter how many of each food you have to see which humans that stock already covers.
  5. Tick the rack repair, growth energy, fresh water and memory checkboxes before retrieving a Human Seed. Follow the Lazarus Complex guide for the setup.

Minimum Stat Thresholds

Height: 30 cm; weight: 20 kg; life expectancy: 10 years. A food total below any of these minimums needs more food before cultivation can begin.

Choosing Foods

Ingredient totals use the 12 confirmed recipes. Nanite Infusion has two conflicting recipes and is excluded from ingredient totals. Immune Boost reads 5 for each physical attribute on a November 2025 game screen and 6 on the wiki; the calculator uses 6, so check it in your game. For the fewest food items for a profession, use Human Recipes.

Human Calculator FAQ

What does The Last Caretaker Human Calculator calculate?

It answers three questions: which food grows a chosen profession, whether a food mix clears the Lazarus Rack minimums, and which humans your food stock can grow. For a food mix it totals height, weight, life expectancy, strength and intellect and checks the rack minimums. Ingredient totals use confirmed recipes; disputed recipes are excluded.

What are the minimum stat thresholds for Lazarus Racks?

Height must be at least 30 cm, weight at least 20 kg, and life expectancy at least 10 years. Meeting these food thresholds does not replace repairing the rack and supplying power, fresh water and memory items.

Where can I find a human recipe for a specific profession?

Choose Grow a profession at the top of this page and pick the profession: the Human Calculator finds the fewest food items that meet its documented physical requirements and lists the memory targets it still needs. Human Recipes compares every profession side by side.

Which professions can my food combination grow into?

Once your foods meet the rack minimums, the Human Calculator lists every profession whose food requirements (height, weight, life expectancy, strength and intellect) your total already meets, with the memory targets each still needs. A human who meets several professions can turn out as a different one than you tracked, so keep the extra matches low.

Does the Human Calculator include memory items?

Not as items yet. Memory item values vary from item to item, so the calculator shows each profession's memory targets, such as focus, patience and logic, instead of adding memory items to the totals.

Which game version are the food stats based on?

The food data combines November 2025 screens with some post-Update 5.5 checks. It has not all been rechecked in the current build; each food shows its sources and version, and conflicting readings are flagged.

Can this tool calculate the cheapest food recipe?

No automatic cheapest-combination search is provided. It totals ingredients for your selected foods using the 12 confirmed recipes. Nanite Infusion is excluded because its recipes disagree. Food attributes are confirmed except Immune Boost, which uses the wiki values with a visible disagreement warning.
