Free worldbuilding economy calculator. Define your custom currency (e.g. 1 gold = 10 silver = 100 copper) and an economic tier, then generate a consistent price sheet for food, lodging, tools, weapons, and luxury goods.

Use when fleshing out a new setting's economy. Internal consistency matters more than absolute numbers — players will spot it when a sword costs less than dinner.
A grounded alternative to random-table price generators. Both your peasant's daily wage and the legendary sword's price stay in proportion.
Exchange rate: 1 gold = 10 silver = 100 copper.

A tavern meal is anchored at 5 copper pieces. Every other item is priced relative to it using the chosen economic tier multiplier (×0.5 grimdark, ×1 standard, ×0.7 wealthy, ×0.6 sci-fi).
The exchange rate is 1 gold = 10 silver = 100 copper. You can rename the denominations to fit your setting.
Items are grouped into food, lodging, tools, weapons, and luxury so you can see the relative scale at a glance.
Prices are anchored to a tavern meal at 5 copper pieces; everything else is multiplied by the economic tier.

A common everyday purchase gives players an intuitive reference point, so prices feel consistent relative to something they understand. Anchoring to a meal keeps weapons, lodging, and luxuries in believable proportion to daily life.
Pick whole-number ratios that are easy to do mental math with, such as 1 gold = 10 silver = 100 copper. Avoid awkward conversions like 7 or 13 to a coin, since players have to track these at the table.
Input
Standard medieval, "gold/silver/copper" naming.
Output
Tavern meal: 5 copper · Short sword: 10 gold · Riding horse: 75 gold.
Prices anchor to a 5-copper meal. Standard medieval multiplier ×1 keeps the canonical D&D-style values; switch to "grimdark" to roughly double everything except wages.
The standard tier follows the familiar decimal-ish scheme of copper, silver and gold with fixed ratios between them. Historical coinage rarely worked that way — the pre-decimal English system ran 12 pence to a shilling and 20 shillings to a pound, and the awkwardness was the point of a lot of period bookkeeping.
A tidy ratio is easier at the table and a messy one is more evocative. The tool converts either; which you want is a tone question.
The failure worth designing around is the high-denomination coin that is useless in play. If a gold piece buys a week of a labourer's work, no villager can change one, and a party that loots a chest of gold cannot buy bread with it.
Historically that was true and it created a genuine texture — big coins were for merchants, soldiers were paid in small ones, and changing money was a service. Whether you want that friction or want a party to spend gold freely at a village inn is a decision better made deliberately than discovered mid-session.
