The gem cutting calculator is a calculator using current exchange prices which shows you how much money you will lose or gain by successfully cutting one of each gem type assuming you buy and sell the gems using the grand exchange. Using high or low alchemy may affect how much you lose or gain from cutting gems. Also, buying higher than or selling lower than the current market price (such as buying at highest price or selling at lowest price) will cause you to lose more money when cutting gems.
To determine how much you will lose or gain from cutting more than one gem of the same variety, multiply the number of gems you plan on cutting by the value in the per gem column. To determine how much it will cost per level, multiply the amount of crafting XP until the next level by the value in the per XP column.
