Tools
Practical calculators built from cited game mechanics. Each public tool explains its formula, limits, source data, and the route decision it is meant to support.
Power Runtime Calculator
Select a battery, direct downstream device count, and night length to calculate runtime and the remaining safety margin.
Open Calculator →Crafting Material Planner
Search curated route-critical recipes and expand known sub-components into a quantity-aware raw material estimate.
Open Planner →Route Buff Prep Planner
Choose a route type, flag prep risks, and turn wiki-checked food buffs and debuffs into a practical checklist.
Open Planner →Skill Perk Planner
Calculate remaining cumulative XP and see the confirmed perk milestones crossed before a selected skill target.
Open Planner →Backpack Route Planner
Reserve outbound and loot slots, compare pack capacity, and check route-specific storage or mobility coverage.
Open Planner →Verified Soup Planner
Match exact inventory items to a curated set of verified soup recipes with per-portion stats and direct source links.
Open Planner →Radiation Protection Planner
Calculate treatment recovery, check documented debuff thresholds, and compare source-backed protective gear values.
Open Calculator →Sandbox Config Builder
Generate a reviewed SandboxSettings.ini block for enemy, XP, inventory, loot, and night-power options.
Open Builder →Trader Exchange Planner
Multiply exchange costs, check unlock conditions, and compare a planned run with listed trader stock.
Open Planner →Enemy Matchup Planner
Check reviewed damage weaknesses, resistances, and immunities before choosing a route loadout.
Open Planner →Armor Set Comparison Planner
Filter three reviewed upgrade lines by armor role, full-set weight, and whether another upgrade stage remains.
Compare Armor →Vehicle Route Planner
Check seats, cargo capacity, activation items, route freedom, and documented sectors before a transport run.
Plan Transport →Water Logistics Planner
Convert a clean-water target into boiling batches or filter fills, then check tainted-water input and container capacity.
Plan Water Supply →Storage Capacity Planner
Count total slots, reserve fully shielded capacity, and calculate a capacity-first crate addition.
Plan Storage →Portal Reset Planner
Find the next server-clock reset boundary and check documented blockers and the native-stove warning.
Check Reset →Chemistry Batch Planner
Multiply verified tincture ratios, check the 8-unit flask cap, and calculate missing Distillations.
Plan Chemistry →Synchrotron Repair Planner
Track three repair-part trades, installed parts, pipe pumps, and the next confirmed Manufacturing West objective.
Plan Repair →Security Clearance Planner
Match a door's clearance level to a Keypad Hacker or Gatekey and see whether your current device can open it.
Check Access →Crafting Bench Upgrade Planner
Combine upgrade materials, subtract inventory, and check Crafting level requirements without counting installed upgrades twice.
Plan Upgrades →How tools are published
A calculator is only listed here after its inputs map to a public mechanic, its result can be checked by hand, and its limitations are written next to the interactive controls.
Tool review standard
Public tools are meant to answer repeatable planning questions, not replace route judgment. The power calculator starts with the most common base failure: a battery survives one night in testing, then fails after one extra refrigerator, charger, or workbench is wired downstream. The tool keeps the arithmetic visible so a player can decide whether to add another battery, shorten the circuit, or move nonessential devices to a separate line.
What belongs in this tool index
Repeatable route choices
A tool must help with a decision players repeat across runs: whether a battery circuit is safe, which ingredient route is shorter, or when a resource loop is worth the risk. One-off trivia and keyword-only calculators are not published here.
Visible limits
If a mechanic changes with a patch, depends on wiring layout, or ignores player behavior, the tool states that limit near the result. A calculator should make uncertainty easier to reason about, not hide it behind a clean number.
