Item value is determined by a number of factors: the form of the item, the material it is made out of, the quality of its creation, and any decorations on it.
The final value of an item is the base value of the form of the item (e.g. block or statue) multiplied by the material multiplier (e.g. granite or gold), multiplied by the quality modifier (e.g. fine or masterful) if any, then summed with the final value of all decorations.
Base values of items[edit]
The base value of an item is determined by the form of the item, not what it is made out of. For example, a wood block uses the base value for a block; a native gold block uses the same base value, since it too is in the form of a "block". In both cases, the final value is then determined by adjusting the base value with the appropriate modifiers.
Items without quality levels[edit]

- Notes:
- 1) Coins minted at a forge are always of base quality
- 2) Goods made out of cloth get the following built in as decorations: the cloth (with quality mod) and the thread (without quality). Dyes are added separately (with quality), as a powder, not a decoration.
- 3) "Decorations" include "It is decorated with <material>", "It is encircled with bands of <material>", "It is adorned with hanging rings of <material>", "This object menaces with spikes of <material>", "On this object is an image of <description> in <material>", "It is studded with <metal>". Decorations of bolts have a 1/3 base value instead.
- 4) Prepared meals always have a base value of 1, with a quality modifier, but the ingredients also affect the final value.
- 5) These items have their value based on their properties - see categories below:
Prepared meal[edit]
This table shows how the quality modifiers compare to other items:
| Quality | Ingredient | Meal | Value Modifier | Meal Bonus |
|---|---|---|---|---|
| (normal) | minced | (none) | 1.0× | +0 |
| -Well-Crafted- | well-minced | well-prepared | 1.1× | +3 |
| +Finely-crafted+ | finely minced | finely-prepared | 1.2× | +6 |
| *Superior quality* | superiorly minced | superiorly prepared | 4/3× | +10 |
| ≡Exceptional≡ | exceptionally minced | exceptional prepared | 1.5× | +15 |
| ☼Masterful☼ | masterfully minced | masterfully prepared | 2.0× | +30 |
The value of a stack of prepared meals is equal to the material multiplier of the main ingredient (multiplied by the meal's base value of 1) times the meal's quality modifier (finely-prepared, etc.), plus the products of each ingredient's base value and its quality modifier (well-minced, etc.), with the sum of the ingredient values divided by the total number of ingredients, all multiplied by the stack size. So, for example: a well-prepared meal consisting of 5 finely-minced cow cheese, 3 finely-minced llama tripe, 1 finely-minced llama sweetbread, and 2 superiorly minced mussels would be "-mussel roast [11]-", worth 88☼ (for 62☼ of ingredients). (Exact calculation: ([1 * 1 * 11/10 + 3] + ([10 * 1 * 6/5] + [2 * 1 * 6/5] + [2 * 1 * 6/5] + [2 * 1 * 4/3])/4) * (5 + 3 + 1 + 2))
This example can be understood as:
(base value of prepared meal = 1☼) × (mussel material multiplier = 1) × (well-prepared = 11/10) + (meal bonus = 3) = 4.1, rounded down to 4 + ( (value of cheese = 10☼) × (cow material multiplier = 1) × (finely-minced = 5/4) = 12 + (value of tripe = 2☼) × (llama material multiplier = 1) × (finely minced = 5/4) = 2.4, rounded down to 2 + (value of sweetbread = 2☼) × (llama material multiplier = 1) × (finely minced = 5/4) = 2.4, rounded down to 2 + (value of fish = 2☼) × (mussel material multiplier = 1) × (superiorly minced = 4/3) = 2.66, rounded down to 2 ) ÷ 4 = 4.5, rounded down to 4 all multiplied by the total number of meals (11) = 88☼
Because all math is performed with integers (with the results always rounded down), ingredient quality modifiers typically will not have any visible effect for low-value ingredients.
The individual stack sizes of the ingredients may affect your profits, but have no effect on the final meal's value. One "masterfully minced plump helmet" cooked with ten "well-minced dog meat" will have exactly the same value and description as ten "masterfully minced plump helmet" and one "well-minced dog meat".
The quality symbols shown in the name of a meal reflect the highest quality involved in its making, looking at the overall preparation as well as the mincing of each ingredient. With up to five jobs involved, monetary values of apparently same-quality meals can vary a lot, and a lower-quality meal can be more valuable than a higher-quality meal cooked from the same ingredients.
Weapon[edit]
- The base value of a melee weapon is (SIZE / 50) + 1; if the weapon has any EDGE attacks, its value is doubled. Ranged weapons simply have a value of 10.
[show]Weapon values
Ammo[edit]
- The base value of a single unit of ammo is (SIZE / 200) + 1.
[show]Ammo values
Value listed is for a single bolt, not stacks of bolts. Multiply the single value by the stack size for total value of a stack. (e.g. 1 bar of metal = stack of 25 bolts, etc.)
Shield[edit]
- The base value of a shield is (UPSTEP * 3) + BLOCKCHANCE + 1.
- UPSTEP cannot be greater than 3
- BLOCKCHANCE cannot be greater than 100
[show]Shield values
Headwear[edit]
- The base value of a helm is (LAYER_SIZE / 5) + (COVERAGE / 20) + 1.
- LAYER_SIZE and COVERAGE cannot be greater than 100
[show]Helm values
Armor / torso[edit]
(Note - When DF speaks of clothing, "armor" refers to anything worn on the torso, i.e. shirts, vests, togas, robes, etc., which all do provide some small protection, as well as breastplates and chain shirts. Combat-quality "armor" pieces are listed here by their location.)
- The base value of a piece of armor is ((UBSTEP + LBSTEP) * 3) + (LAYER_SIZE / 5) + (COVERAGE / 10) + 1.
- UBSTEP and LBSTEP cannot be greater than 3
- LAYER_SIZE and COVERAGE cannot be greater than 100
[show]Armor values
Legwear[edit]
- The base value of a pair of pants is (LBSTEP * 3) + (LAYER_SIZE / 5) + (COVERAGE / 10) + 1
- LBSTEP cannot be greater than 3
- LAYER_SIZE and COVERAGE cannot be greater than 100
[show]Pants values
Hand- & footwear[edit]
- The base value of a shoe or glove is (UPSTEP * 3) + (LAYER_SIZE / 5) + (COVERAGE / 30) + 1.
- UPSTEP cannot be greater than 3
- LAYER_SIZE and COVERAGE cannot be greater than 100
[show]Glove values
[show]Shoe values
- * Gauntlets and boots are made 2 at a time from a single bar, effectively doubling the total value of the final items.
Material multipliers[edit]
| Material properties |
| Defined: Value • Color • Density • Strain at yield • Temperature values |
| Derived: Magma safety • Fire safety |
| Fluids: Depth • Flow • Pressure |
The material multiplier for an item is found from the [MATERIAL_VALUE:#] tag in the raws for the material it is made out of, and can be further augmented using [MULTIPLY_VALUE:#]. A wood block uses the same material multiplier as a wood log or a wooden chest - that is the material value for wood, which is 1.
