How many levels, lapis and XP an enchanting table needs to take an item from one level to another — accounting for bookshelf count.
An enchanting table never grants an enchantment for free: each step costs experience, and the higher the level, the more expensive the next one. The calculator totals the full cost of moving between two levels.
Two things affect that cost: the item type sets the enchantment cap, and the number of bookshelves sets how high you can actually reach. The base cap is 15 and each shelf adds one, but 30 is the hard ceiling.
Lapis cost is calculated separately. Normally one lapis is worth one level, but with 15 or more bookshelves a lapis is worth two.

Fifteen. The base cap is 15 and each shelf adds one, so 15 shelves reach the hard limit of 30. More shelves add nothing.
Each item type has its own cap set by the game's developers: rod 8, bow 9, weapon 10, diamond armour 12, book 15. The table cannot exceed it.
It's the experience you have to accumulate beforehand, equal to the level cost multiplied by that level's price for the item — for example 5 per level on a plain sword.
With 15 or more bookshelves each lapis is spent on two levels instead of one, roughly halving the lapis cost for large enchantments.
Items have different caps: fishing rod 8, bow 9, weapon 10, diamond armour 12, book 15.
