Calculators


 * For more information about the current market prices, or to update outdated prices, see Grand Exchange Market Watch.

Calculators are used to determine experience points, and item manufacture costs based on real-time prices in the Grand Exchange Market Watch. Calculators are normally used by players to determine the profits (or losses) they make while levelling up a particular skill. This reduces the need for players to actually go to the Grand Exchange, and determine the current market prices of items. There are a number of calculators available here to help players with their calculations.

Opportunity costs
All raw material costs used in the calculators are based on real-time prices from the Grand Exchange Market Watch. This assumes that the player is buying items from the Grand Exchange, even if these items are easily obtainable from alternative locations.

This is due to the fact that using an item as a raw material prevents the player from selling that item on the Grand Exchange, thereby effectively "costing" the player the amount of money they could have sold it for. In business, this concept is called Opportunity cost and should be considered when calculating the actual cost using raw materials.

For example:
 * When Prayer potions are made, Snape grass is one of the ingredients (raw material) used for making this potion. Snape grass can easily be found on the Hobgoblin peninsula, south-west of the Crafting Guild, and south of Falador. However, the player could sell the Snape grass on the Grand Exchange for  coins each. So, using it to make Prayer potions has effectively cost them coins for each potion made, even though they got Snape grass for free.

The same concept applies to any ores mined, or any animal hides collected instead of being bought from the Grand Exchange. This may sound counter-intuitive, but ignoring it distorts the actual cost of making items and gives incorrect figures.
