What is the OSRS Farming Calculator?
The OSRS Farming Calculator is an essential tool for Old School RuneScape players looking to optimize their in-game farming activities. Farming is a skill in OSRS that allows players to grow various plants, trees, and herbs in designated patches across Gielinor. It's a popular skill for generating passive income (GP), gaining experience (XP), and acquiring essential supplies for other activities like Herblore and Cooking.
This calculator is designed for anyone who wants to maximize their efficiency, whether you're an ironman needing specific resources, a skiller aiming for 99 Farming, or a player looking for consistent daily GP. It helps you understand the potential returns from different crops under various conditions.
A common misunderstanding about OSRS Farming is that it's always profitable or always high XP. In reality, market prices fluctuate, and optimal strategies depend heavily on your farming level, available items (like Magic Secateurs), and the type of compost you use. Without proper planning, a farming run can sometimes result in a loss or suboptimal XP gain. This **OSRS Farming Calculator** aims to demystify these variables, providing clear estimates for your efforts.
OSRS Farming Formula and Explanation
The calculations within this **OSRS Farming Calculator** are based on core OSRS mechanics for yield, experience, and disease. While the exact underlying game formulas can be complex, involving multiple random rolls and probabilities, this calculator uses averaged and simplified models to provide reliable estimates.
Key Formulas Explained:
- XP per Patch: `Base XP (planting) + Base XP (checking health per stage) + Base XP (harvesting)`
- Disease Chance: `Base Disease Chance (per crop) * Compost Multiplier * Protection Factor * Diary Bonus`
- Average Yield per Patch: `(Average Base Yield * (1 + Magic Secateurs Bonus + Attas Plant Bonus)) * (1 - Effective Disease Chance)`
- GP Profit/Loss: `(Total Yield * Produce Price) - (Number of Patches * Seed Price) - (Number of Patches * Protection Cost)`
- Per Hour Metrics: `(Per Run Value / Growth Time in Minutes) * 60`
Please note that "Effective Disease Chance" in the yield formula accounts for patches dying if not protected. If a patch is protected, its disease chance is 0, and thus the yield is maximized.
Variables Table:
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Farming Level | Your current skill level | Level | 1-99 |
| Crop Type | Specific plant being grown | N/A | Ranarr, Watermelon, Yew, etc. |
| Number of Patches | How many patches of this type you utilize | Patches | 1-10 (herbs/allotments), 1-6 (fruit trees), 1-5 (trees) |
| Compost Type | Quality of compost used | N/A | None, Compost, Supercompost, Ultracompost |
| Pay for Protection | Whether you pay an NPC to protect the patch | Boolean (Yes/No) | True/False |
| Magic Secateurs | Equipped item increasing yield | Boolean (Yes/No) | True/False |
| Attas Plant Active | Benefit from an active Attas plant on Anachronia | Boolean (Yes/No) | True/False |

| Seed Price | Cost of one seed on the Grand Exchange | GP | 1 - 1,000,000+ |
| Produce Price | Selling price of one harvested item on the Grand Exchange | GP | 1 - 1,000,000+ |
| Protection Cost | Cost paid to the farmer for protection | GP | 0 - 200,000 |
Practical Examples with the OSRS Farming Calculator
Example 1: Profitable Ranarr Herb Run
Let's say you're a mid-level player aiming for consistent profit with your **OSRS Farming Calculator**.
- Farming Level: 70
- Crop Type: Ranarr
- Number of Patches: 9 (all available herb patches)
- Compost Type: Ultracompost
- Pay for Protection: Yes (using Snape Grass)
- Magic Secateurs: Yes
- Attas Plant Active: No
- Morytania Hard Diary: No
- Seed Price: 50,000 GP (Ranarr seed)
- Produce Price: 7,000 GP (Ranarr herb)
- Protection Cost: 6,000 GP (Snape Grass value)
Results (approximate using the calculator): A single run might yield around ~450,000 GP Profit and ~10,000 XP. With a growth time of 80 minutes, this translates to roughly ~337,500 GP/hr and ~7,500 XP/hr, making Ranarrs a very solid choice for profit.
Example 2: Efficient Watermelon Allotment Run
Now, consider a player focusing on XP and some supplies, perhaps for cooking, using an allotment crop with varying compost types.
- Farming Level: 50
- Crop Type: Watermelon
- Number of Patches: 4 (standard allotment patches)
- Compost Type: Supercompost
- Pay for Protection: No
- Magic Secateurs: Yes
- Attas Plant Active: No
- Morytania Hard Diary: No
- Seed Price: 100 GP (Watermelon seed)
- Produce Price: 250 GP (Watermelon)
- Protection Cost: 0 GP
Results (approximate using the calculator): This run could give about ~4,000 GP Profit and ~2,500 XP per run. With a growth time of 40 minutes, this results in about ~6,000 GP/hr and ~3,750 XP/hr. If you were to switch to 'None' for Compost, you would see a significant drop in both yield and profit due to increased disease chance.

Key Factors That Affect OSRS Farming Profit and XP
Understanding the variables that influence your farming runs is crucial for maximizing efficiency. The **OSRS Farming Calculator** takes these into account:
- Farming Level: Higher levels unlock more profitable and higher XP crops (e.g., Redwood trees at 90 Farming). It also slightly improves overall yield and reduces the chance of disease.
- Crop Choice: Different crops offer vastly different XP and GP rates. Herbs like Ranarrs and Snapdragons are often highly profitable, while trees (e.g., Yew, Magic) provide significant XP but are usually a GP loss. Allotments like Watermelons can be a good balance.
- Compost Type: This is one of the most critical factors. Ultracompost drastically reduces disease chance (90% reduction) and provides the highest yield bonus, making it almost always worth the investment for valuable crops. Supercompost and regular compost offer diminishing returns.
- Paying for Protection: For high-value crops, paying an NPC (e.g., a farmer, or using specific items like Snape Grass for herbs) to protect your patches is almost always recommended. It guarantees no disease, ensuring you get the full yield and avoid wasted seeds/time.
- Magic Secateurs: Equipping Magic Secateurs (or their upgraded variants) provides a flat 10% bonus to yield when harvesting herbs and allotments. This is a significant boost to profit and should always be used if available.
- Attas Plant: Having an active Attas plant in the Anachronia farming guild provides a 5% yield boost to all farming patches across Gielinor. While a late-game unlock, it's a passive and valuable bonus.
- Market Prices: The Grand Exchange prices for seeds and harvested produce fluctuate daily. A crop that is highly profitable one week might be less so the next. Regularly checking prices or using the "Override Price" feature in the **OSRS Farming Calculator** is vital for accurate profit estimates.
- Morytania Hard Diary: Completing this diary grants a permanent disease-free herb patch in Canafis, effectively making it a guaranteed profit patch for herbs without needing to pay for protection.
Frequently Asked Questions about OSRS Farming
- Q: Why is my calculated GP profit negative?
- A: This can happen if the cost of your seeds and protection is higher than the value of your harvested produce. This is common for high-XP crops like trees. Market price fluctuations can also turn a profitable run into a loss. Always check current Grand Exchange prices.
- Q: How does compost affect my farming run?
- A: Compost primarily reduces the chance of your crops getting diseased and can slightly increase yield. Ultracompost offers the best benefits, significantly lowering disease risk (by 90%) and providing the highest yield bonus, making it highly recommended for valuable crops.
- Q: What are Magic Secateurs and why are they important?
- A: Magic Secateurs are a tool that, when equipped, provide a 10% boost to the yield of herbs and allotments. This directly increases your profit and XP per run, making them an essential item for efficient farming.
- Q: Should I always pay for protection?
- A: For high-value crops like most herbs and fruit trees, paying for protection is highly recommended. It guarantees your patch won't get diseased, ensuring you don't lose your initial seed and protection investment. For low-value crops, the cost of protection might outweigh the risk of losing a patch.
- Q: How accurate are the prices in the calculator?
- A: The default prices are estimates based on typical Grand Exchange values. OSRS market prices fluctuate constantly. For the most accurate results, it's best to use the "Override Price" options and input current Grand Exchange prices before each calculation.
- Q: What's the fastest way to 99 Farming?
- A: The fastest way to 99 Farming typically involves planting the highest-level trees and fruit trees you can afford and checking their health. These grant large bursts of XP. Herbs and allotments provide more consistent, smaller XP gains but are generally more profitable.
- Q: Can I use this calculator for Ironmen?
- A: Absolutely! While ironmen don't trade on the Grand Exchange, they can value items based on their effort or utility. You can use the "Override Price" fields to input your own subjective values for seeds (e.g., if you buy them from a store) and produce (e.g., how much a herb is worth for a potion). This helps ironmen plan resource acquisition.
- Q: What does "Attas Plant Active" mean?
- A: The Attas plant is one of the Anachronia growth variants. If you have an active Attas plant growing in the Anachronia farming guild, it provides a passive 5% yield boost to all farming patches across Gielinor. It's a high-level farming unlock.
