OSRS Farming Profit Calculator: Maximize Your Gains in Old School RuneScape


Farming in Old School RuneScape (OSRS) is a skill that offers both experience and profit potential, making it a favorite among players looking to grow their in-game wealth. Whether you’re planting herbs, trees, or special crops, understanding your profit margins can transform your farming runs into a gold-making machine. That’s where an OSRS Farming Profit Calculator comes in—a tool designed to help you estimate costs, yields, and profits with precision. In this blog post, we’ll dive into how these calculators work, the best crops to farm for profit, and tips to optimize your farming strategy in OSRS as of April 2025.

An OSRS Farming Profit Calculator is an online tool that calculates the expected yield, cost, and profit of your farming runs based on real-time Grand Exchange (GE) prices and your farming setup. These calculators take into account variables like seed costs, compost types, yield boosts, and disease rates, giving you a clear picture of your potential earnings.

Why Use a Farming Profit Calculator?

Without a calculator, estimating profits can be a guessing game. You might plant a batch of ranarr seeds only to realize the profit barely covers your costs—or worse, you’re in the red. A calculator eliminates the uncertainty by providing data-driven insights tailored to your specific inputs.

Key Features of a Good Calculator

  • Real-Time GE Prices: Updates seed, herb, and compost prices daily.
  • Yield Estimates: Factors in your Farming level, compost, and boosts like magic secateurs.
  • Customizable Inputs: Allows you to adjust for disease-free patches, diaries, and equipment.
  • Profit Breakdown: Shows costs vs. revenue per run or per patch.

Not all crops are created equal when it comes to profit. Let’s explore the most lucrative options for your farming runs in OSRS, based on current market trends and calculator data.

Herb Farming: The Gold Standard

Herbs are the backbone of farming profit in OSRS, thanks to their high demand for Herblore training. Here are the top herb seeds to consider:

  • Ranarr Seeds: A perennial favorite due to prayer potions. Average profit per patch can exceed 50k GP with ultracompost and boosts.
  • Toadflax Seeds: Cheaper seeds with solid returns, often yielding 20-30k GP per patch.
  • Snapdragon Seeds: High-value herbs for super restores, netting 40-60k GP per patch.

Tree and Fruit Tree Runs

Tree runs offer passive profit with less frequent attention. While slower than herbs, they’re a great supplement:

  • Magic Trees: Seeds cost around 100k GP, but logs can yield 150-200k GP profit per tree.
  • Palm Trees: Coconut harvests can net 50-70k GP per run with minimal upkeep.

Special Crops for Niche Profits

Special crops like calquat trees or cactus spines can surprise you with their returns:

  • Calquat Trees: Low seed cost (200 GP) and fruit worth 5-10k GP.
  • Cactus Spines: Steady profit of 10-15k GP per harvest with disease resistance.

How to Use an OSRS Farming Profit Calculator

Using a farming profit calculator is straightforward, but knowing how to input your data correctly is key to accurate results. Here’s a step-by-step guide:

Step 1: Choose Your Crop

Select the seed type (e.g., ranarr, magic, or palm) from the calculator’s dropdown or input field. This sets the foundation for cost and revenue calculations.

Step 2: Input Your Farming Setup

Enter details like:

  • Your Farming level (affects yield).
  • Number of patches (e.g., 9 herb patches with quests completed).
  • Compost type (ultracompost is recommended for max profit).
  • Boosts (magic secateurs, Farming cape, Kandarin Diary).

Step 3: Analyze the Results

The calculator will output:

  • Total Cost: Seeds, compost, and protection payments.
  • Expected Yield: Average harvest based on your inputs.
  • Profit: Revenue minus costs, often per run and per patch.

Example Calculation: Ranarr Herb Run

Input Value
Seed Cost 30k GP
Patches 9
Ultracompost Cost 1k GP each
Average Yield 7 herbs/patch
Herb Price 10k GP each

Total Cost: (30k × 9) + (1k × 9) = 279k GP
Total Revenue: 7 × 9 × 10k = 630k GP
Profit: 630k – 279k = 351k GP per run

Optimizing Your Farming Runs for Maximum Profit

To get the most out of your farming calculator results, you need to optimize your strategy. Here are actionable tips to boost your profits in OSRS.

Use Disease-Free Patches

Unlock disease-free patches (e.g., Trollheim, Hosidius, Weiss) to reduce crop deaths and increase yields. These patches can push your average herb yield from 6 to 8+ per patch, significantly hiking profits.

Invest in Boosts

Equipment and diary rewards amplify your returns:

  • Magic Secateurs: 10% yield boost for herbs.
  • Farming Cape: Additional yield increase.
  • Kandarin Diary: Up to 15% extra yield on herb patches.

Time Your Runs Efficiently

Herbs take 80 minutes to grow, while trees can take days. Plan your runs to coincide with your playtime—do herb runs every 1-2 hours and check trees daily for a steady income stream.

Minimize Costs

Use the bottomless compost bucket to halve compost costs over time, and grow your own protection crops (e.g., white lilies) to avoid payment fees for fruit trees.
