OSRS Herb Run Profit Formula
The calculation is based on the total revenue generated minus the total cost incurred across all farming patches used in a single run.
Profit per Run = [ (Avg. Yield per Patch * Herb Price) - (Seed Cost + Consumable Cost) ] * Number of Patches
Formula Sources: OSRS Wiki – Farming Herbs, Runescape Wiki – Profit Calculator Guide
Variables Explained
Understanding the inputs is key to accurate results:
- Number of Patches Used: The quantity of herb patches you actively use per run (typically 8-9).
- Herb Price (GP): The current market price (or Grand Exchange price) of the harvested herb.
- Herb Seed Cost (GP): The cost of the specific seed used per run, including any re-plant cost if patches die.
- Avg. Herb Yield per Patch (Qty): The average number of herbs you receive from one successful patch (influenced by Farming level and compost used).
- Consumable Cost per Patch (GP): Cost of Ultracompost, magic secateurs tax (if applicable), or payment to farmers.

What is an OSRS Herb Run Calculator?
An OSRS Herb Run Calculator is a specialized tool designed for the game Old School Runescape (OSRS). It helps players determine the expected profit or loss from performing a full circuit of herb patches. Farming herbs is one of the most reliable and consistent passive income methods in the game, making the calculation of its profitability crucial for efficient gameplay.
The calculator aggregates multiple dynamic variables—namely seed cost, herb selling price, average harvest yield, and total patch count—to provide a single, actionable GP value. This allows players to compare the effectiveness of growing different herbs (e.g., Ranarr vs. Snapdragon) and adjust their farming strategy to align with current Grand Exchange prices.
How to Calculate Herb Run Profit (Example)
- Determine Net Profit per Seed: Start by calculating the base value gained per seed planted. If a single patch yields 9 herbs at 5,000 GP each (45,000 GP total), and the seed costs 10,000 GP, the profit is 35,000 GP (before compost/consumables).
- Factor in Consumable Cost: Subtract any recurring costs, such as the price of Ultracompost (e.g., 1,500 GP) or farmer payment. The net profit per seed becomes 33,500 GP.
- Multiply by Patch Count: Multiply the net profit per seed (33,500 GP) by the total number of patches used in the run (e.g., 8 patches).
- Final Result: The total expected profit for the entire run is 33,500 GP * 8 = 268,000 GP.
Frequently Asked Questions (FAQ)
- What is the most profitable herb to grow? The most profitable herb constantly changes based on the Grand Exchange price fluctuations, which is why a real-time calculator is essential. Historically, Ranarrs, Snapdragons, and Torstols frequently compete for the top spot.
- How often should I do a herb run? A herb run takes approximately 80 minutes to grow. Most players perform a run roughly every 1 hour and 20 minutes to maximize their daily yields, although longer gaps will not harm the crops.
- Does using Ultra Compost increase my profit? Yes. Ultra Compost dramatically reduces the chance of a patch dying and slightly increases the average yield, significantly boosting the overall consistency and expected profit of your run compared to using no compost or Supercompost.
- What is the maximum number of patches available? With all necessary quests completed (including Kourend and Kandarin hard diaries), you can utilize 9 dedicated herb patches in a single run.
