OSRS Herb Run Profit Calculator
Estimate expected profit per herb run, day, week, and month using your own prices and yield assumptions.
How this herb run calculator works
This calculator is built for Old School RuneScape players who want to quickly evaluate whether a herb run is worth doing. It combines your expected yield, herb prices, and run costs into one clear profit estimate.
Instead of guessing, you can compare herbs like Ranarr or Snapdragon and decide where your farming time gives the best return. Since prices move constantly, this tool is most accurate when you update seed and herb values before each session.
Core formula used
Step-by-step math
- Expected herbs per run = patches × average herbs per patch × survival rate
- Revenue per run = expected herbs × herb sell price
- Total seed cost = patches × seed cost
- Total run cost = seed cost + compost cost + travel cost
- Profit per run = revenue − total run cost
- Profit per day/week/month = profit per run × runs over each period
What to enter for best accuracy
1) Average herbs per patch
This is the number that drives most of your estimate. If you use ultracompost, magic secateurs, and disease-free methods, your yield rises. If you are unsure, start around 7.5–9.0 and adjust after tracking real runs.
2) Survival rate
Survival rate reflects how many planted patches actually finish successfully. If you protect certain patches or use disease-resistant methods, you can safely raise this percentage.
3) True run costs
Include all costs you pay repeatedly: seeds, compost, and travel resources. Many players underestimate teleport or route cost, which can slightly inflate projected profits.
Tips to improve herb run profit
- Check Grand Exchange prices before large seed buys.
- Use a consistent route to reduce time and missed patches.
- Track your real average yield over 20+ runs.
- Compare profit and active GP/hour, not just total gp.
- Switch herb type when margins tighten.
Common mistakes players make
- Using outdated prices from yesterday or last week.
- Ignoring survival rate and assuming all patches live.
- Forgetting compost expense in per-run calculations.
- Overvaluing a herb because of occasional lucky yields.
Final note
A herb run calculator is best used as a decision aid, not a guarantee. Real profits fluctuate with market movement, patch outcomes, and your own route efficiency. Recalculate often, keep your assumptions realistic, and you will make much better farming decisions over time.
