This calculator is intended to help you manage your kingdom for maximum profit on the Grand Exchange.

Prices of the items being traded can vary by quite a bit, so there isn't necessarily a "best" option. You should also take your own training goals into consideration when choosing what to produce, but keep in mind that it may be better to sell more profitable items from your kingdom and use those profits to buy cheaper training materials.

This table assumes you have already completed either Throne of Miscellania (giving you 10 available subjects) or Royal Trouble (giving you 15 subjects and more options), that you make the maximum daily investment (50,000 coins; 75,000 coins if you've completed Royal Trouble) and that you maintain 100% approval. Your approval rating is multiplied by your investment every time money is removed from your coffers (once every 24 hours); these daily values are all then added together to determine how many resources you collect from your subjects, so lower approval ratings or investments will reduce profitability, and it is therefore recommended that you maximize your approval rating and fill your coffers often. Note: After completion of Royal Trouble, yield falls by about 0.5% per day as approval drops. Players may find raising approval only every week or so to be a reasonable tradeoff between time spent visiting Miscellania and the number of resources they collect.

Only 10 subjects can be assigned to any given task, so the table below is calculated on the assumption that 50,000 coins (50,000 coin investment * 100% approval rating, or 75,000 coin investment * 100% approval rating * 10/15 subjects) are directed toward that task. No more than 10% of your coffers will be removed each day, so in order to make the maximum daily investment, your coffers must have at least 500,000 coins (750,000 coins if you've completed Royal Trouble). If you've completed Royal Trouble, it's recommended that you assign your 5 additional subjects to the second-most profitable task (for an additional profit of half of what's calculated in the table).

Additional rewards are difficult to take into account monetarily. However, upon collecting your resources, you'll receive 1 Bird's nest per 100 Maple logs or per 350 Teak/Mahogany logs, 1 Gem per 150 Coal, 1 Herb seed per 100 Herbs or 600 Flax, and occasional Gems and Caskets from fishing.

Take into account:

• Caskets, Herb seeds, Gems and Bird's nests can significantly alter the profitability of fishing, herb-picking/farming, mining and woodcutting.

• Key halves and Level 1 Clue Scrolls are sometimes found fishing; clue scrolls cannot be found if you already have one.

• Farming requires a significant number of bank spaces, especially over longer periods (at least 55 products in combination with fishing).

Production options Edit

This table assumes you've completed both Throne of Miscellania and Royal Trouble; completing only Throne of Miscellania will yield significantly fewer resources, and it's therefore recommended you make any and all efforts toward completing both quests.

Task	Quantity Produced per Day	Minimum Net Profit	Expected Net Profit	Notes
Mining	542 Coal	&0000000000102104000000 102,104	&0000000000113798000000 113,798	Due to the random nature of Gems, the Expected Net Profit may vary by a few thousand gp. The GE Value and Minimum Net Profit assume all gems received are Sapphires.
Woodcutting	892 Maple logs	&0000000000001228000000 1,228	&0000000000054076000000 54,076	Due to the random contents of nests, only the value of the Crushed nests received are accounted for in the GE Value and Minimum Profit calculations. Estimated probabilities of nest contents are used to calculate the Expected Profit. Use a Bird's nest with a pestle and mortar to make a Crushed nest, worth &0000000000001386000000 1,386 each. Remember, 1 nest is received per 100 logs, so 9 nests will be collected for most days, while only the 8 received on the first day are taken into account for these calculations (it is therefore recommended you do not collect every day, in order to further increase profitability). Further, some players choose to craft their maple logs into Unstrung Maple Shieldbows, yielding an additional profit of &0000000000041924000000 41,924 (for a total of about &0000000000096000000000 96,000). Keep in mind that this requires level 55 fletching and about half an hour of work per day of rewards collected.
Fishing (cooked)	440 Tuna and 132 Swordfish 4 Misc. (Uncut Gems, Caskets, key halves, Fremennik Boots/Gloves, Level 1 Clue Scroll)	&0000000000045812000000 45,812	&0000000000061404000000 61,404	The amount of money earned from a clue scroll (if received) can change the amount of money earned by quite a lot. Minimum Profit and GE Value calculations assume no clue scroll rewards or key halves and that all gems received are Sapphires.
Fishing (raw)	440 Raw tuna and 132 Raw swordfish 4 Misc. (Uncut Gems, Caskets, key halves, Fremennik Boots/Gloves, Level 1 Clue Scroll)	&0000000000073136000000 73,136	&0000000000088728000000 88,728	The amount of money earned from a clue scroll (if received) can change the amount of money earned by quite a lot. Minimum Profit and GE Value calculations assume no clue scroll rewards or key halves and that all gems received are Sapphires.
Herbs	61 Herbs	&0000000000088028000000 88,028	&0000000000103452000000 103,452	1 Herb seed is received per 100 herbs picked; however, it is difficult (if even possible) to take their value into account without wild variation. Thus, GE Value and Minimum Profit calculations are not truly minimal; they are the expected values based on estimated herb distributions, assuming no money is made from herb seeds.
Herbs (Flax)	1250 Flax	&-1-1-1-1-1-1-1-1-1-1-1-3-3-500000000 -22,500	&-1-1-1-1-1-1-1-1-1-1-1-3-3-500000000 -22,500	Flax will yield one Herb seed per 600 Flax picked. These seeds are not taken into account calculating GE Value and Minimum Profit. Spinning the flax into bow strings is time consuming, but will yield an enormous profit: &0000000000106250000000 106,250
Hardwoods (Teak)	301 Teak logs	&-1-1-1-1-1-1-1-1-1-1-1-2-6-4-9-5000000 -15,385	&-1-1-1-1-1-1-1-1-1-1-1-2-6-4-9-5000000 -15,385	Teak generally costs more to produce than it's worth on the GE. It's recommended that if you need teak, you instead use your profits from Managing Miscellania to buy it.
Hardwoods (Mahogany)	204 Mahogany logs	&0000000000065260000000 65,260	&0000000000065260000000 65,260	Some players opt to use the Lunar Spell Plank Make, yielding a profit of &0000000000210304000000 210,304, not including the cost of runes. (&-1-1-1-1-1-1-1-1-1-1-1-3-3-7-5-4000000 -22,644 for the Nature Runes, &-1-1-1-1-1-1-1-1-1-1-1-6-5-7-8-2000000 -54,672 for the Astral Runes.)
Hardwoods (both)	121 Teak logs and 121 Mahogany logs	&0000000000032280000000 32,280	&0000000000032280000000 32,280	Teak generally costs more to produce than it's worth on the GE. It's recommended that if you need teak, you instead use your profits from Managing Miscellania to buy it.
Farming	Various seeds	&-1-1-1-1-1-1-1-1-1-1-1-20-2-2-9000000 -19,119	&-1-1-1-1-1-1-1-1-1-1-1-20-2-2-9000000 -19,119	The type of seed you get greatly changes the amount of money produced.
Idle	Nothing produced	&-1-1-1-1-1-1-1-1-1-1-1-50000000000 -50,000	&-1-1-1-1-1-1-1-1-1-1-1-50000000000 -50,000	Placing workers in this section will be a complete loss of income.
