Eco Calorie Price Calculator

📋 Overview

This tool calculates credit prices for crafted items in the game Eco using calorie-based economics. You build a recipe database, configure your character's skills and crafting table upgrades, then look up any item to see its fully-loaded cost — including all nested sub-ingredients — converted to credits at your server's calorie rate.

All data (recipes, skills, tables, tags) is stored in your browser's localStorage. Use Export to back up your database and Import to restore or share it. Use ↺ Reload JSON in the header to re-fetch the latest recipe data from the JSON files.

⚡ Quick Start

1. Configure skills

On the ⚡ Pricer page, set each skill to your character's in-game star level using the Skills & Tables panel on the left.

2. Add your recipes

Switch to the 📖 Recipes page. Click + New to add an item, or ↺ Seed Raws to pre-populate common raw materials. You can also Import a JSON export. By default, all vanilla recipes in the version listed in the header should be included.

3. Set the calorie rate

On the ⚡ Pricer page, enter your server's Credits per Calorie in the calculator settings bar (e.g. 1.6 if 1000 cal = 1600 credits).

4. Price an item

Type an item name in the search box on the Pricer page and press Enter, or click any item in the Recipes list and press ⚡ Price It.

🗂 Layout

The app has two pages toggled by the tab bar in the header. Your last viewed page is remembered.

⚡ Pricer

The main pricing view. Skills & Tables are always visible on the left; the calculator and cost tree are on the right. Changes to skill levels or table upgrades immediately recalculate the current result.

📖 Recipes

The recipe database. The left panel lists all items (or tags); the right panel shows a read-only detail view for the selected item, or the edit form if you click ✎ Edit.

↺ Reload JSON

Fetches the latest data from recipes.json, skills.json, tables.json, and item-tags.json, merging in any market prices and skill levels you have already set. Requires the app to be served over HTTP — it will not work when opened directly as a file:// URL.

🧮 Pricer Page

Skills & Tables panel

Always visible on the left of the Pricer page. Set each skill's star level (0–7) and lavish workspace checkbox, and assign upgrade modules to crafting tables. Any change immediately recalculates the current result. Click ↺ Reset to restore all skills to level 1 and all tables to No Upgrade.

Skill Level (0–7)

Matches the star rating shown in-game. Level 0 = not learned (100% labor). Level 7 = fully specialised (50% labor). Multipliers: 0→100% 1→80% 2→75% 3→70% 4→65% 5→60% 6→55% 7→50%

Lavish Workspace

Applies an additional −5% to all reducible ingredient quantities for that skill.

Table Upgrade

Ranges from No Upgrade (×1.0) through Basic I–IV, Advanced I–IV, up to Specialized (×0.50). Reduces reducible ingredient quantities and, if Table mod affects labor is checked, also reduces labor.

Credits per Calorie

Your server's calorie-to-credit conversion rate. All prices scale linearly with this value.

Currency Symbol

Cosmetic label shown next to prices (e.g. $, ¢, G).

Profit Margin %

Percentage markup added on top of base cost. Per-item overrides are available in the editor.

Craft Modifier

Global multiplier applied to all reducible ingredient quantities — useful for server-wide rate changes. Does not affect non-reducible ingredients or labor.

Search & Qty

Type an item name and press Enter to price it. Use the Qty field to price a batch. If an item has multiple recipe variants, a dropdown lets you choose which one to use.

Cost tree

Shows the full recursive ingredient breakdown. Labor is shown in teal, byproducts in green (as savings), missing recipes in red. Click any parent node to collapse or expand its subtree. Ctrl+click collapses or expands the entire tree at once.

📖 Recipes Page

Items / Tags toggle

Switch the left panel between Items (recipe database) and 🏷 Tags (item tag groups). The search bar filters whichever view is active.

Group By

In Items view, sort alphabetically (A–Z) or group by Type, Skill, or Crafting Table.

Issues badge

The ⚠ N issues badge appears when there are data quality problems. Click it to filter the list to two categories: Missing Recipes (ingredients referenced in recipes that have no entry in the database) and Unpriced Raws (raw materials with no market price and no labor cost set). Click a missing recipe card to create it pre-filled with that name.

Item detail view

Clicking an item opens a read-only summary in the right panel showing recipe tabs, ingredient tables, byproducts, and a What uses this? reverse-ingredient lookup. From here you can:
• ⚡ Price It — switch to the Pricer page and calculate its cost
• ✎ Edit — open the full edit form

+ New

Create a new blank item and open the editor.

↺ Seed Raws

Adds common raw materials to the database without overwriting existing items. Set each raw's Market Buy Price or Labor Points to reflect your server's costs.

✏️ Item Editor

Click ✎ Edit in an item's detail view to open the editor. Fields apply to the item as a whole unless noted as per-recipe.

Item Name

The item's display name — what other recipes reference when listing this as an ingredient.

Market Buy Price

Fixed cost in credits per unit. When set, the calorie calculation is bypassed — the item is treated as a direct credit purchase. Leave blank to calculate from the recipe tree.

Item Tags

Comma-separated tag names this item belongs to (e.g. Ore, Metal). See Item Tags.

Multiple Recipes

An item can have multiple recipe variants (e.g. two different material options). Use the tabs to switch between them. Click ★ Set Default on the tab you want used in cost calculations and as the initial selection in the Pricer dropdown.

Recipe Label

(per-recipe) A name for this variant shown in the tab and Pricer dropdown.

Skill / Crafting Table

(per-recipe) Must match names in the Skills & Tables panel (case-insensitive). The skill level and table upgrade determine the labor and ingredient modifiers.

Labor Points

(per-recipe) Labor consumed per craft batch, as shown in the Eco UI. Treated as 1:1 with calories. For raw materials, set this to the gathering cost.

Qty Produced / Min. Level / Profit Override

(per-recipe) Units produced per batch; minimum skill level required; per-recipe profit margin override (overrides the global setting when set).

Ingredients

Items consumed per craft. The Red. checkbox marks reducible ingredients — those scaled by the table upgrade, lavish workspace, and craft modifier. Uncheck for fixed costs.

Byproducts

Side-effect outputs whose calorie value is subtracted from the total cost.

🏷️ Item Tags

Some Eco recipes accept any item from a category (e.g. "any Ore"). Item Tags model this — a tag is a named group of items that can be used as an ingredient name in a recipe.

Viewing tags

On the 📖 Recipes page, click the 🏷 Tags toggle to see all tag groups. Click a tag to view its members and set a market price for the group.

Assigning items to tags

Open an item in the editor and type a tag name in the Item Tags field. The tag is created automatically and the item is added as a member. Multiple tags are comma-separated.

Using tags as ingredients

In a recipe's ingredient list, type the tag name (it appears with a [tag] label in autocomplete). The cost is the average of all member items' calculated costs.

Tag market price override

In the Tags view, click a tag and set a Market price for the group. When set, this replaces the member average — useful when you buy all items of a category at a fixed market price.

Tag display in cost tree

Tags appear in purple with a "tag · avg of N" badge. Market-priced tags show a "market" badge instead.

💾 Import / Export

Export

Opens a panel with your full database as JSON — items, skills, tables, and item tags. Copy and save this text to back up or share your setup.

Import

Paste a JSON export to load a database. This merges into your current data (existing items are overwritten by the import). Use the Schema tab for the expected format.

JSON format: An array of item objects. Each item needs at minimum a name and a recipes array.

[ { "name": "Wooden Chair", "recipes": [{ "label": "Default", "skill": "Carpentry",
                "craftingTable": "Workbench", "laborPoints": 200, "outputQty": 1,
                "ingredients": [{"name": "Wood Board", "qty": 4}], "byproducts": [] }] } ]

Raw materials have no ingredients and use laborPoints for the gathering cost, or set a marketPrice on the item to use a fixed credit cost.

📐 Cost Calculation Formula

Costs are calculated recursively — each ingredient's full tree is resolved before the parent is totalled.

reducible_mult = table_upgrade × lavish(0.95 if on) × craft_modifier
labor_mult     = skill_level_modifier × table_upgrade*
* only if "Table mod affects labor" is checked

ingredient_cal = Σ ( qty × reducible_mult × ingredient_cost_cal ) ← reducible
               + Σ ( qty × ingredient_cost_cal ) ← non-reducible
labor_cal      = laborPoints × labor_mult × batches_needed
byproduct_cal = Σ ( byproduct_qty × byproduct_cost_cal )

net_cal        = ( labor_cal + ingredient_cal − byproduct_cal ) / output_qty
price         = net_cal × credits_per_calorie × ( 1 + profit% / 100 )

Market-priced items bypass the formula — their cost is market_price × credits_per_calorie⁻¹ calories.
Tag ingredients cost the average of all member items' net_cal values, or the tag's market price override if set.
