Herb Run Profit Calculator for Old School RuneScape
Pick your patches, compost and boosts, choose a herb and read the expected profit and XP per run. The table ranks every herb at live Grand Exchange prices, with disease and the GE tax included.
Every herb at your settings
Reading the result
Each patch contributes expected herbs = lives ÷ (1 − chance to save) × chance to survive. The chance to save depends on your level and the herb, boosted by secateurs, cape, attas and diaries; the chance to survive is (1 − disease per cycle)³ unless the patch is disease-free. Revenue is herbs × grimy price after tax; cost is seeds plus compost for every patch, dead or alive. The formula page has the exact constants and a worked example; the XP calculator turns the XP into levels.
FAQ
How many herbs do you get per patch?
A patch has 3 harvest "lives", plus 1, 2 or 3 with compost, supercompost or ultracompost. Each herb you pick has a chance not to use a life; that chance grows with your Farming level, magic secateurs (+10%), the Farming cape (+5%), an attas plant (+5%) and the Catherby or Kourend diaries. Expected herbs = lives ÷ (1 − chance to save). At 99 with ultracompost and secateurs that is about 9.2 per living patch.
Does the calculator include dead patches?
Yes. Disease is rolled at the end of three growth cycles: 27, 14, 6 or 3 chances in 128 per cycle for no compost, compost, supercompost and ultracompost. Troll Stronghold, Weiss and Harmony Island never get diseased; Hosidius is disease-free with the easy Kourend & Kebos diary and Civitas illa Fortis with Colosseum champion rank. A dead patch still costs the seed and the compost.
Which prices are used?
Seeds and compost at the Grand Exchange instant-buy price, grimy herbs at the instant-sell price minus the 2% GE tax (you can switch the tax off). Prices come from the OSRS Wiki real-time prices API and refresh every five minutes.
Why is a cheaper herb sometimes more profitable than ranarr?
Profit per run is herbs × price minus seeds × cost. Ranarr and snapdragon seeds are expensive, so when their herb price dips a cheap seed like toadflax or irit can net more per run even though each herb sells for less. The table ranks all herbs at the current prices.
