Farming Run Profit & XP Calculator

What is OSRS Farming?

Old School RuneScape (OSRS) Farming is one of the oldest and most popular non-combat skills in the game. It involves planting seeds or saplings in designated farming patches across Gielinor and tending to them until they mature, yielding crops, herbs, fruit, or other valuable resources. Farming is unique because it operates on real-world time, meaning your crops grow even when you’re logged off. This makes it an excellent skill for players who have limited playtime but still want to make progress and earn in-game currency (GP).

Who Should Use the OSRS Farming Calculator:

• Newer players: To understand the basic costs and potential profits of different crops and plan their early farming strategy.
• Mid-level players: To optimize their runs, choosing crops that offer the best GP/XP balance for their current level and available resources.
• Ironman players: To meticulously track seed/sapling costs and potential yields, crucial for self-sufficient economies.
• High-level players: To quickly assess the profitability of high-tier crops like Torstol or Harmonised run seeds, especially for maximizing profit.
• Anyone looking to make gold: Farming is a consistent and relatively low-risk method to generate GP, and this calculator helps make informed decisions.

Common Misconceptions:

• Farming is too slow: While it uses real-world time, efficient runs and using high-yield patches can make it a significant source of XP and GP over time.
• All crops are equally profitable: Different crops have vastly different buy/sell prices, yields, and XP rates, making some significantly more profitable than others.
• Farming requires constant attention: Once planted, most crops only require checks and tending every few hours or once a day, making it ideal for skilling during other activities.
• XP rates are fixed: While the base XP is listed, certain items like Ultracompost or Guardian boots can slightly alter XP gains, but the calculator focuses on the base rates for simplicity.

OSRS Farming Calculator Formula and Mathematical Explanation

The OSRS Farming Calculator is designed to provide a clear picture of the financial and experience gains from a single farming run. It simplifies the process by focusing on the key variables involved in growing a specific crop across multiple patches.

Core Calculation Logic:

The calculator estimates profit and experience based on the following principles:

Profit Calculation:

Profit is determined by subtracting the total cost of seeds/plants from the total revenue generated by harvesting the crops.

Total Revenue = (Yield Per Patch × Sell Price Per Item) × Number of Patches

Total Cost = Buy Price Per Seed/Plant × Quantity Planted

Profit Per Run = Total Revenue – Total Cost

Experience (XP) Calculation:

Experience gained is directly proportional to the amount harvested and the XP awarded per harvested item.

Total XP Per Run = XP Per Harvest × Yield Per Patch × Number of Patches

Variables Explained:

Understanding the inputs is crucial for accurate calculations:

Farming Calculator Variables

Variable	Meaning	Unit	Typical Range / Notes
Crop Type	The specific plant being grown (e.g., Cabbage, Torstol). Affects yield, XP, and price.	N/A	Selected from a predefined list.
Quantity Planted	The total number of seeds or saplings used.	Count	Minimum 1. Usually matches the number of patches used if planting seeds individually.
Buy Price Per Seed/Plant	The cost to acquire one seed or sapling.	GP	Varies widely. E.g., 10-100 GP for basic seeds, 2,000-10,000+ GP for higher-level seeds.
Sell Price Per Item (Harvest)	The average Grand Exchange price of one harvested unit (e.g., one allotment of cabbages, one herb).	GP	Highly variable based on crop type and game economy. E.g., 50-100 GP for cabbages, 5,000-15,000+ GP for herbs.
Yield Per Patch	The average number of items harvested from a single farming patch.	Count	Varies by crop. E.g., Potatoes: 3, Cabbages: 4, Watermelons: 6, Herbs: 1.
XP Per Harvest	The base experience gained for harvesting one unit (item).	XP	Varies by crop. E.g., Potatoes: 8, Cabbages: 11, Herbs: 65-250+.
Number of Patches Used	The total number of farming patches you tend to during a run.	Count	Typically 8-15 depending on unlocked patches (e.g., Allotments, Herb, Fruit Tree, Flower, Hop, Tree, etc.).

The primary result combines the calculated profit and XP, giving players a clear metric for evaluating the efficiency of their chosen crop.

Practical Examples (Real-World Use Cases)

Let’s illustrate how to use the OSRS Farming Calculator with practical scenarios:

Example 1: Optimizing Herb Runs (Mid-Level Player)

A player wants to run herbs for a balance of profit and experience. They have access to 10 patches (including 1 herb patch) and are considering planting Cadantine.

• Crop Type: Cadantine
• Quantity Planted: 10 (one seed per patch)
• Buy Price Per Seed/Plant: 1,500 GP
• Sell Price Per Item (Harvest): 7,000 GP (average for Cadantine seeds)
• Yield Per Patch: 1 (Herbs always yield 1 per seed)
• XP Per Harvest: 210 XP
• Number of Patches Used: 10 (assuming other patches are filled with lower-value crops or empty)

Using the Calculator:

• Total Cost: 1,500 GP × 10 = 15,000 GP
• Total Revenue: (1 × 7,000 GP) × 10 = 70,000 GP
• Profit Per Run: 70,000 GP – 15,000 GP = 55,000 GP
• Total XP Per Run: 210 XP × 1 × 10 = 2,100 XP

Interpretation: This run yields a substantial profit of 55,000 GP and 2,100 XP. This makes Cadantine a highly profitable herb choice for mid-level players, justifying the seed cost.

Example 2: Maximizing Profit with Fruit Trees (High-Level Player)

A high-level player wants to maximize profit using Fruit Trees, specifically Papaya trees, as part of their extended farming routine. They have 5 fruit tree patches available.

• Crop Type: Papaya Fruit Tree
• Quantity Planted: 5 (one sapling per patch)
• Buy Price Per Seed/Plant: 5,000 GP (approx. for saplings)
• Sell Price Per Item (Harvest): 1,500 GP (each Papaya fruit sells for ~300 GP, typically yields 5)
• Yield Per Patch: 5 (Papayas)
• XP Per Harvest: 420 XP (Total XP for harvesting all 5 papayas)
• Number of Patches Used: 5 (focusing only on fruit tree patches)

Using the Calculator:

• Total Cost: 5,000 GP × 5 = 25,000 GP
• Total Revenue: (5 × 1,500 GP) × 5 = 37,500 GP
• Profit Per Run: 37,500 GP – 25,000 GP = 12,500 GP
• Total XP Per Run: 420 XP × 5 = 2,100 XP

Interpretation: While the profit per run seems moderate (12,500 GP), fruit trees are known for their high XP rates per tree cycle. This run provides 2,100 XP, making it a good investment for players prioritizing experience alongside steady income. The actual profit can be higher if players choose to sell the fruit directly instead of waiting for the tree to fully mature for harvesting.

How to Use This OSRS Farming Calculator

Using the OSRS Farming Calculator is straightforward. Follow these steps to get accurate profit and experience estimations for your farming runs:

1. Select Crop Type: Choose the specific plant you are growing from the ‘Crop Type’ dropdown menu. The calculator will pre-fill typical values for yield and XP, but these can be manually adjusted.
2. Enter Quantity Planted: Input the total number of seeds or saplings you are using. This is usually equal to the ‘Number of Patches Used’ if you plant one seed per patch.
3. Input Buy Price: Enter the cost you paid for each seed or sapling. This could be from the Farming shop, seeds you’ve obtained, or Grand Exchange prices.
4. Input Sell Price: Enter the estimated selling price per harvested item. Check the Grand Exchange for current market rates.
5. Specify Yield Per Patch: Input how many items you typically harvest from a single patch for the selected crop. (Note: For herbs, this is usually 1, but the XP is listed per harvest cycle).
6. Enter XP Per Harvest: Input the experience gained for each harvested item/unit.
7. Set Number of Patches: Enter the total number of farming patches you are utilizing in this run.

Reading the Results:

• Primary Result (Large Font): This shows your estimated profit (GP) and total experience (XP) for one complete cycle of the chosen crop across all your patches.
• Total Cost: The total GP spent on seeds/saplings for this run.
• Total Revenue: The total GP you expect to earn from selling the harvested items.
• Profit Per Run: The net profit (Revenue – Cost). A positive number means profit, a negative number means a loss for this cycle.
• Total XP Per Run: The total experience points gained from harvesting all items in this run.

Decision-Making Guidance:

Use the results to compare different crops. If your primary goal is GP, focus on crops with high ‘Profit Per Run’. If you’re aiming for faster leveling, look for crops with high ‘Total XP Per Run’. Often, there’s a trade-off, and you’ll need to balance your priorities based on your current OSRS goals.

Key Factors That Affect OSRS Farming Calculator Results

While the calculator provides a solid estimate, several in-game and external factors can influence your actual profit and experience gains:

1. Grand Exchange Market Fluctuation: The ‘Sell Price Per Item’ is the most volatile input. GE prices change constantly based on player supply and demand. High-tier herbs like Torstol or unique items from Farming like Spirit Tree fruits can see significant price swings. Always check current GE prices before making assumptions.
2. Seed/Sapling Availability and Cost: The ‘Buy Price Per Seed/Plant’ can also fluctuate. Sometimes, specific seeds might be temporarily out of stock or surge in price due to events or popular demand for certain potions or items. Farming Guild favor can also unlock better seed prices.
3. Yield Variance: While the calculator uses an average ‘Yield Per Patch’, actual yields can vary slightly due to random events or specific game mechanics. Using the best farming equipment and optimal ultracompost can sometimes marginally increase yields.
4. Number of Patches Accessible: The ‘Number of Patches Used’ directly scales profit and XP. Players with more farming quests completed and higher Farming levels will unlock more patches (e.g., Hosidius, Kourend, Farming Guild patches), significantly boosting potential income and XP rates per hour.
5. Compost and Ultracompost Usage: Using compost, super compost, or ultracompost significantly reduces the chance of crop disease, increasing the likelihood of a successful harvest and maximizing yield. This implicitly affects profit by ensuring your investment doesn’t go to waste. Ultracompost is particularly vital for high-value crops.
6. Player Level and Gear: Higher Farming levels unlock more lucrative crops and increase the base XP gained. Certain gear, like the Farming cape or Golden Tench, can offer minor benefits. While not directly in the calculator’s core formula, these contribute to overall efficiency.
7. Time Investment vs. Profit/XP: The calculator shows profit/XP *per run cycle*. However, some crops mature faster than others. A crop with slightly lower profit per run but a much shorter growth cycle might be more profitable *per hour* if you can perform more runs in that time.
8. Event Bonuses and Updates: Jagex occasionally introduces farming-related events or updates that might affect crop prices, yields, or XP rates, temporarily altering the profitability calculations.

Frequently Asked Questions (FAQ)

Q1: How often should I do my farming runs?

Ideally, you should do runs every 8-12 hours to check on your crops. Some crops, like herbs and certain trees, require more frequent checks to prevent disease or maximize harvest. For maximum efficiency, checking every 6-8 hours is recommended.

Q2: What is the best crop for profit in OSRS Farming?

Generally, high-level herbs like Torstol, Snapdragon, and Cadantine offer the best profit margins per run due to their high Grand Exchange prices. However, always check current market prices as they fluctuate.

Q3: What is the best crop for experience in OSRS Farming?

For raw experience, certain fruit trees (like Magic or Dragonfruit) and hardwood trees provide substantial XP per growth cycle. Some players also utilize Dragonfruit or specific high-level herbs for rapid leveling.

Q4: Does the calculator account for growth times?

No, this calculator focuses on the profit and XP gained *per harvest cycle*. It does not factor in how long each crop takes to grow. For hourly rates, you would need to divide the total profit/XP by the crop’s growth time.

Q5: What are ‘Quantity Planted’ and ‘Number of Patches Used’?

‘Quantity Planted’ is the total number of seeds/saplings you buy. ‘Number of Patches Used’ is how many distinct farming spots you are checking. For basic allotments, these are often the same if you plant one seed per patch. For trees, you plant one sapling per patch.

Q6: Should I use compost or ultracompost?

Using compost, super compost, or ultracompost is highly recommended, especially for herbs and higher-level crops. Ultracompost drastically reduces the chance of crop disease, ensuring your investment yields results and maximizing profit/XP. The calculator assumes a successful harvest.

Q7: How do I find the current prices for seeds and harvests?

The best way is to use the Grand Exchange interface in-game or third-party OSRS price guide websites (like the OSRS Wiki or GE-Tracker). Input these current prices into the calculator for the most accurate results.

Q8: Can I use this calculator for Farming Contracts?

Yes, you can use this calculator to determine the profitability of the crops required for Farming Contracts. By inputting the contract’s required crop, you can see if the potential profit justifies the seed cost and time investment.
