What is OSRS Farming?

Old School RuneScape (OSRS) Farming is a non-combat skill that allows players to cultivate various plants, trees, and crops to gain experience and often valuable resources. It involves planting seeds or saplings in designated patches across Gielinor, tending to them (often by protecting them from disease), and eventually harvesting the mature produce. Farming offers a steady and relatively low-risk way to train, making it a popular choice for players of all levels looking to increase their overall stats or generate in-game wealth.

Who Should Use the OSRS Farming Calculator?

The OSRS Farming Calculator is designed for:

• New Players: To understand the basic costs and potential profits of different crops and plan their early farming activities.
• Mid-Game Players: To optimize their farming runs by choosing the most profitable or experience-efficient crops based on current Grand Exchange prices and available patches.
• Ironman Accounts: While profit isn’t the primary goal, they can use the calculator to estimate XP gains and resource acquisition.
• Skiller Players: Those focused on non-combat skills can use it to maximize efficiency and plan their training.
• Anyone Seeking Efficiency: Players who want to maximize their Return on Investment (ROI) in terms of both time and in-game currency.

Common Misconceptions about OSRS Farming

Several misconceptions surround OSRS Farming:

• “Farming is only for money.” While many crops are profitable, some like Herbs and Trees offer significant experience bonuses and are crucial for certain quests or achievements.
• “All farming patches are the same.” Different patches have unique benefits or restrictions. For example, fruit trees require specific saplings, while herbs are vulnerable to disease without proper protection.
• “You always need ultra compost.” While Ultra Compost significantly boosts yield and reduces disease chance, it’s not always cost-effective for every crop. Basic compost or even no compost might be sufficient depending on the plant and player goals.
• “Farming takes too long.” With efficient routing and proper planning, farming runs can be done quickly, often in under 10 minutes, fitting into breaks or between other activities.

OSRS Farming Calculator Formula and Mathematical Explanation

The OSRS Farming Calculator aims to provide a clear picture of the potential financial and experience gains from a single farming run. It breaks down the calculation into several key components:

Core Calculation Steps:

1. Calculate Total Harvested Items: This is the total amount of produce you can expect to gather from all your farming patches.
2. Calculate Total Planting Cost: This is the total upfront cost incurred for seeds, saplings, or produce needed to plant all the patches.
3. Calculate Total Revenue: This is the potential income generated from selling all harvested items on the Grand Exchange.
4. Calculate Estimated Profit Per Run: This is the net gain after subtracting the total costs from the total revenue.
5. Calculate Total XP Gained: This includes experience from both planting and harvesting, depending on the crop type.
6. Calculate Profit Per Item: This helps understand the profitability of each individual item harvested.

Variable Explanations

Let’s break down the variables used in the calculator:

Variable	Meaning	Unit	Typical Range
Average Yield Per Plant	The average number of items harvested from a single crop instance (e.g., 10 potatoes per potato plant).	Items	1 – 50+ (varies greatly)
Number of Patches Used	The total count of distinct farming patches the player utilizes in a run.	Patches	1 – 15+
Planting Cost Per Patch	The cost of seeds, saplings, or other consumables required to plant one patch.	Coins	0 – 20,000+
Average Sale Price Per Item	The current Grand Exchange price for one unit of the harvested item.	Coins	1 – 1,000,000+
XP Per Plant	Experience gained specifically for the act of planting in a patch.	XP	0 – 100+
XP Per Harvest	Experience gained for successfully harvesting items from a patch.	XP	0 – 200+

Mathematical Formulas

The calculator uses the following formulas:

Total Harvested Items = Average Yield Per Plant * Number of Patches Used

Total Planting Cost = Planting Cost Per Patch * Number of Patches Used

Total Revenue = Total Harvested Items * Average Sale Price Per Item

Estimated Profit Per Run = Total Revenue - Total Planting Cost

Total XP Gained = (Number of Patches Used * XP Per Plant) + (Total Harvested Items * XP Per Harvest)

Profit Per Item = Estimated Profit Per Run / Total Harvested Items (If Total Harvested Items > 0)

Note: These calculations provide an estimate. Actual results may vary due to random events, disease, patch variations, and fluctuating Grand Exchange prices. The formulas assume you harvest the entire yield from each patch.

Practical Examples (Real-World Use Cases)

Example 1: High-Level Herb Run (Ranarr Weed)

A player wants to perform a farming run focusing on Ranarr Weed for both profit and experience.

• Plant Type: Herb Farming (Ranarr Weed)
• Average Yield Per Plant: 12 Ranarr Weed leaves
• Number of Patches Used: 6 (Assuming the player has access to 6 herb patches)
• Planting Cost Per Patch: 2,500 coins (Ranarr seed cost)
• Average Sale Price Per Item: 600 coins (Ranarr Weed price)
• XP Per Plant: 45 XP
• XP Per Harvest: 18.5 XP

Calculation:

• Total Harvested Items = 12 leaves/plant * 6 patches = 72 leaves
• Total Planting Cost = 2,500 coins/patch * 6 patches = 15,000 coins
• Total Revenue = 72 leaves * 600 coins/leaf = 43,200 coins
• Estimated Profit Per Run = 43,200 coins – 15,000 coins = 28,200 coins
• Total XP Gained = (6 patches * 45 XP/plant) + (72 leaves * 18.5 XP/leaf) = 270 XP + 1,332 XP = 1,602 XP
• Profit Per Item = 28,200 coins / 72 leaves = 391.67 coins/leaf

Interpretation: This herb run is estimated to yield a profit of 28,200 coins and 1,602 XP. Each Ranarr leaf harvested contributes approximately 392 coins to the profit.

Example 2: Tree Run (Yew Tree)

A player is training Farming using Yew trees, focusing on XP and long-term investment.

• Plant Type: Yew Tree
• Average Yield Per Plant: 3 Yew logs
• Number of Patches Used: 3 (Player uses the three main tree patches)
• Planting Cost Per Patch: 15,000 coins (Yew sapling cost)
• Average Sale Price Per Item: 300 coins (Yew log price)
• XP Per Plant: 7,500 XP (for planting the sapling)
• XP Per Harvest: 840 XP (per log harvested)

Calculation:

• Total Harvested Items = 3 logs/tree * 3 trees = 9 logs
• Total Planting Cost = 15,000 coins/tree * 3 trees = 45,000 coins
• Total Revenue = 9 logs * 300 coins/log = 2,700 coins
• Estimated Profit Per Run = 2,700 coins – 45,000 coins = -42,300 coins
• Total XP Gained = (3 trees * 7,500 XP/tree) + (9 logs * 840 XP/log) = 22,500 XP + 7,560 XP = 30,060 XP
• Profit Per Item = -42,300 coins / 9 logs = -4,700 coins/log

Interpretation: This tree run is highly unprofitable on a per-run basis (-42,300 coins), indicating a net cost. However, it provides a substantial amount of experience (30,060 XP). This highlights that tree runs are primarily an experience training method, with the cost offset by the high XP rates. The revenue from logs is secondary and doesn’t cover the sapling cost.

Key Factors That Affect OSRS Farming Results

Several dynamic factors can significantly influence the actual profit and experience gained from your OSRS Farming runs. Understanding these helps in setting realistic expectations:

1. Grand Exchange (GE) Prices:

   This is arguably the most volatile factor affecting profitability. Both the price of seeds/saplings (cost) and the price of harvested produce (revenue) fluctuate constantly based on supply and demand. Regularly checking current GE prices is crucial for accurate calculations.

2. Yield Variation:

   The ‘Average Yield Per Plant’ is an estimate. Actual yields can vary due to factors like patch disease, the effectiveness of disease-repelling items, and the use of specific composts (like Super or Ultra Compost). Higher yields directly increase revenue and profit.

3. XP Rates & Calculation Method:

   Different crops offer vastly different XP rates. Some, like herbs and trees, are primarily for XP, while others like potatoes are low XP but potentially profitable. The calculator uses standard XP values, but specific actions like using a farming cape perk might slightly alter gains.

4. Compost Usage:

   Using composts (Normal, Super, Ultra) can improve yields and reduce the chance of disease. Ultra Compost offers the best benefits but is the most expensive. The cost of compost needs to be factored into the overall expense if not using the default ‘no compost’ assumption.

5. Disease Chance & Protection:

   Crops can become diseased, potentially halting growth or reducing yield. Players can use items like the ‘Magic Secateurs’ or ‘Healthy’ farming equipment to boost protection. Failing to protect crops can lead to lost profits and XP.

6. Time Investment & Run Efficiency:

   While the calculator focuses on a single run’s potential, the time taken to complete a farming route matters. Efficient routing between patches, using the fastest travel methods (e.g., teleports, spirit trees), and performing actions quickly maximize the profit-per-hour.

7. Player Level & Unlocks:

   Access to certain farming patches (like the Farming Guild) or higher-level crops (like Crystal Trees) is locked behind specific Farming skill levels. This dictates which options are available and potentially more profitable or XP-efficient.

8. Eventual Sale Strategy:

   Are you selling immediately via Grand Exchange, or using the items for other skills (e.g., Herbs for Herblore)? The calculator assumes GE sale prices, but personal use might change the effective “profit.”

Frequently Asked Questions (FAQ)

How accurate is the OSRS Farming Calculator?

The calculator provides estimates based on the input values you provide. Accuracy depends heavily on the real-time accuracy of the Grand Exchange prices and your estimates for yield and XP. It’s a powerful planning tool but doesn’t account for all in-game RNG.

Does the calculator account for disease?

The calculator uses average yield figures. It doesn’t explicitly calculate potential losses due to disease. Using composts or protecting your crops can help achieve yields closer to the average or even higher.

What is the best crop for profit in OSRS Farming?

This changes frequently with Grand Exchange prices. Generally, high-level Herbs and certain Trees (like Redwood or Magic) tend to be profitable while also offering good XP. Checking the calculator with current prices is the best way to determine the current best.

What is the best crop for XP in OSRS Farming?

For pure experience, Trees (especially Mahogany and Teak) and later-stage crops like Crystal Trees or White Trees offer the highest XP rates, though they often come at a net cost per run, meaning you pay coins for XP.

How do I find the XP per plant and XP per harvest values?

These values are generally fixed for each crop type. You can find comprehensive lists on OSRS Wiki or other fan-maintained wikis. The calculator provides some common defaults, but always verify with a reliable source for the specific crop you’re growing.

Can I calculate profit for multiple runs?

Yes, simply multiply the ‘Estimated Profit Per Run’ by the number of runs you intend to complete. However, remember that GE prices can change significantly over time, affecting the profitability of future runs.

Does this calculator work for Farming Guild requirements?

The calculator helps estimate XP gains, which is crucial for reaching Farming Guild level requirements. While it doesn’t directly track reputation, the XP data is essential for that goal.

Why is my profit negative for some crops?

Many high-XP crops, especially Trees and some Herbs, have a higher cost for seeds/saplings than the immediate sale value of their produce. These are considered ‘training methods’ where you pay GP to gain experience faster than more profitable, lower-XP crops.
