What is a D&D Coin Weight Calculator?

A d&d coin weight calculator is an essential utility for Dungeon Masters and players of Dungeons & Dragons (specifically 5th Edition) who utilize encumbrance rules. In the standard ruleset (PHB Chapter 7), carrying capacity is limited by a character's Strength score. While armor and weapons have obvious weights, currency often accumulates unnoticed until it becomes a significant burden.

This tool automates the math required to determine how heavy a character's purse is. Instead of manually dividing coin counts by 50, players can input their copper, silver, electrum, gold, and platinum counts to instantly see the total weight in pounds. It also provides a conversion to a standard Gold Piece (GP) value, helping players decide which low-value, high-weight coins (like copper) might be worth discarding to save weight for more valuable loot.

Many groups ignore coin weight (often called "handwaving"), but for campaigns that focus on realism, survival, or dungeon crawling (like Tomb of Annihilation), a d&d coin weight calculator is vital for accurate inventory management.

D&D Coin Weight Calculator Formula

The mathematical logic behind the d&d coin weight calculator is straightforward, based on the standard 5th Edition Player's Handbook rules. Regardless of the metal type (gold, silver, etc.) or denomination, all standard coins share the same physical weight.

The Core Formula:
Total Weight (lbs) = Total Coin Count ÷ 50

To find the Total Coin Count, we sum the quantities of all denominations held:
Count = CP + SP + EP + GP + PP

Variable Meaning Standard Value Source Rule
CP, SP, EP, GP, PP Coin Denominations Integer Count Player Inventory
Divisor Coins per Pound 50 PHB Ch. 5

Practical Examples

Example 1: The Dragon's Small Hoard

A party defeats a young dragon and finds a pile of loose change. They loot 2,000 CP, 4,000 SP, and 200 GP.

  • Total Coins: 2,000 + 4,000 + 200 = 6,200 coins.
  • Calculation: 6,200 ÷ 50 = 124 lbs.
  • Financial Interpretation: The total value is only 620 GP (20GP from copper, 400GP from silver, 200GP gold). Carrying 124 lbs for 620 GP is inefficient compared to carrying gems or platinum. The party might choose to leave the copper behind.

Example 2: The Rogue's Pockets

A rogue is carrying 50 PP (Platinum) and 100 GP.

  • Total Coins: 150 coins.
  • Calculation: 150 ÷ 50 = 3 lbs.
  • Financial Interpretation: The total value is 600 GP (500 from PP + 100 GP). This is incredibly weight-efficient. High-denomination currency allows characters to carry vast wealth without encumbrance penalties using this d&d coin weight calculator.

How to Use This D&D Coin Weight Calculator

  1. Enter Coin Counts: Input the quantity of Copper (CP), Silver (SP), Electrum (EP), Gold (GP), and Platinum (PP) found on your character sheet.
  2. Adjust Rate (Optional): If your Dungeon Master uses homebrew rules (e.g., "100 coins per pound"), select that option from the dropdown menu. Default is 50.
  3. Review Weight: The "Total Weight" box will update instantly in pounds (lbs). This is the number you add to your inventory's total weight.
  4. Analyze Value: Check the "Total Value (GP)" to see how much your money is actually worth in standard gold pieces.
  5. Optimize: Use the breakdown table to identify heavy, low-value coins to discard if you are over-encumbered.

Key Factors Affecting Results

Several variables can influence the output of a d&d coin weight calculator and how you interpret the data:

  • Carrying Capacity: Your carrying capacity is your Strength score multiplied by 15. If your coin weight plus gear weight exceeds this, you are encumbered.
  • Variant Encumbrance: Many tables use the "Variant Encumbrance" rule where penalties start at Strength × 5. In these games, coin weight is critical.
  • Container Limits: A standard pouch holds 1/5 cubic foot or 6 pounds of gear (about 300 coins). You cannot carry 10,000 coins in a single pouch.
  • Trade Goods: Often, wealth is stored in gems or art objects. These usually have high value-to-weight ratios compared to coins.
  • Exchange Rates: In some settings, silver or electrum might be the standard. This calculator standardizes to Gold (GP) for ease of comparison.
  • Coin Density (Homebrew): Some DMs dictate that gold is heavier than copper. This calculator assumes standard 5e physics where all coins weigh the same.

Frequently Asked Questions (FAQ)

How many coins fit in a bag of holding?

A Bag of Holding can carry up to 500 lbs. Since 50 coins weigh 1 lb, a Bag of Holding can carry exactly 25,000 coins (500 × 50), regardless of type.

Does Electrum weigh more than Gold?

No. In D&D 5th Edition, all coins weigh exactly the same (0.02 lbs each), regardless of the metal used.

Why is my coin weight so high?

You likely have a large amount of Copper or Silver. These coins have low value but high weight. Use the d&d coin weight calculator to see if converting them to Gold or Platinum would solve your weight issue.

What is the weight of 1,000 gold pieces?

1,000 gold pieces weigh exactly 20 pounds in D&D 5e.

How do I calculate value from weight?

You cannot calculate value solely from weight because 1 lb of copper (50 cp, value 0.5gp) weighs the same as 1 lb of platinum (50 pp, value 500gp). You must know the denomination mix.

Is this calculator compatible with Pathfinder?

Generally, yes. Pathfinder 1e and 2e also typically use the 50 coins = 1 lb rule, though you should verify with your specific rulebook.

Does this include the weight of the pouch?

No. This calculator provides the net weight of the raw currency. You must add 1 lb for every pouch or sack you use to carry it.

What is the "Coins Per Pound" setting?

Older editions of D&D sometimes used different weights (e.g., 10 coins/lb). We include this setting to make the d&d coin weight calculator backwards compatible.
