What is {primary_keyword}?
{primary_keyword} is a tool designed for Old School RuneScape players to estimate the total number of herbs they can harvest from a given number of farming patches. It helps players plan their herb runs, maximize profit, and understand how factors like Farming level, compost type, and herb selection affect yields.
Anyone who farms herbs—whether a casual player, a money‑making specialist, or a high‑level farmer—can benefit from this calculator.
Common misconceptions include believing that higher Farming levels always double yields or that compost eliminates disease entirely. This {primary_keyword} clarifies the real impact of each variable.
{primary_keyword} Formula and Mathematical Explanation
The total herb yield is calculated using the following steps:
- Determine the base yield for the selected herb.
- Calculate the level bonus: (Farming Level – Herb Requirement) × 0.1. If the level is below the requirement, the bonus is zero.
- Apply the disease multiplier based on compost: 1 – Disease Chance.
- Combine the values: Total Yield = Patches × Base Yield × (1 + Level Bonus) × Disease Multiplier.
Variables
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Base Yield | Base herbs per patch for the selected herb | herbs/patch | 3‑7 |
| Farming Level | Your Farming skill level | level | 1‑99 |
| Level Bonus | Additional herbs per patch from skill level | herbs/patch | 0‑9.8 |
| Disease Chance | Probability a patch gets diseased | percentage | 5%‑30% |
| Disease Multiplier | Factor reducing yield due to disease | ‑ | 0.70‑0.95 |
| Patches | Number of herb patches being farmed | patches | 1‑100 |
Practical Examples (Real-World Use Cases)
Example 1
Inputs: Herb = Guam, Farming Level = 45, Compost = Supercompost, Patches = 5.
Calculations:
- Base Yield = 3
- Level Bonus = (45 – 1) × 0.1 = 4.4
- Disease Multiplier = 1 – 0.10 = 0.90
- Total Yield = 5 × 3 × (1 + 4.4) × 0.90 ≈ 71 herbs
This means a player can expect about 71 Guam herbs from five patches at level 45 with Supercompost.
Example 2
Inputs: Herb = Ranarr, Farming Level = 80, Compost = Ultracompost, Patches = 10.
Calculations:
- Base Yield = 7
- Level Bonus = (80 – 1) × 0.1 = 7.9
- Disease Multiplier = 1 – 0.05 = 0.95
- Total Yield = 10 × 7 × (1 + 7.9) × 0.95 ≈ 617 herbs
At high levels with Ultracompost, the yield dramatically increases, making Ranarr farming very profitable.

Key Factors That Affect {primary_keyword} Results
- Farming Level: Higher levels increase the level bonus, adding more herbs per patch.
- Herb Type: Different herbs have different base yields.
- Compost Quality: Better compost reduces disease chance, raising the disease multiplier.
- Number of Patches: More patches linearly increase total yield.
- Patch Health: Disease can still occur; the calculator assumes average outcomes.
- World Type: Some worlds have higher disease rates; adjust expectations accordingly.
Frequently Asked Questions (FAQ)
- Can this calculator predict exact herb counts?
- No, it provides an estimate based on average disease chances and level bonuses.
- Does using Ultracompost guarantee no disease?
- Ultracompost reduces disease chance to 5%, but does not eliminate it entirely.
- What if my Farming level is below the herb requirement?
- The level bonus will be zero, and you will only receive the base yield.
- Can I use this calculator for other farming activities?
- This tool is specialized for herb farming; other crops have different formulas.
- How often should I reset the calculator?
- Use the Reset button to return to default values whenever you start a new scenario.
- Is the chart accurate for all levels?
- The chart reflects the current inputs; changing levels updates it dynamically.
- Does the calculator account for herb price fluctuations?
- No, it only estimates quantity, not monetary value.
- Can I share the results with friends?
- Yes, use the Copy Results button and paste the information wherever you like.
