The purpose of this calculator is to determine the best pouches to make if a player has a fixed number of Gold charms and wishes to maximize net total value, where summoning experience has a fixed value in coins and all items are bought and sold on the Grand Exchange. Note that this situation does not exactly match with practical situations because generally, players have a Summonning experience of level goal rather than a fixed charm budget.

For example, Barker toads are often considered better than Spirit terrorbirds, but if a player has a fixed number of Gold charms and has a constant two-way tradeoff between experience and coins which is less than -1.34, then spirit terrorbirds are always preferable. (Again, most people greatly value reaching a certain level goal, such as level 99, so this situation does not match reality.)

This calculator considers a pouch not worthwhile if there is a second pouch with a lesser-or-equal level requirement and a greater xp-adjusted net value. This is because a player who can make the first pouch could always choose to make the second pouch instead. If instead the second pouch had a greater level requirement, then when a player's Summoning level is in between the two level requirements, they can only choose one of the pouches.

This calculator cannot compare pouches made from different charms. In order to perform such calculations, a player should decide on a fixed coin value for each charm, such as 500 for Gold charms and 14,000 for Blue charms. Then, they can subtract 500 from the xp-adjusted net value of all Gold pouches, subtract 14,000 from the xp-adjusted net value of all Blue pouches, and then compare. Of course, this approach is not perfect. Limitations include the effect of Spirit gems and that monsters generally drop a mix of charms.

Note: Spirit mosquitos have a stackable tertiary ingredient. Theoretically, the their xp-adjusted net value may be less than that of lower-levelled pouches but still be considered worthwhile because of their quicker pouch-creation time. In practice, their net value is so low that almost anyone would not consider these pouches worthwhile.
