What this OSRS farming calculator does

This OSRS farming calculator is designed for fast herb-run planning. Instead of guessing your returns, you can estimate expected herbs harvested, profit per run, profit per day, and XP gains based on your exact setup. It is useful for both money-focused players and anyone training Farming while keeping cash flow positive.

Herb profits change constantly with the Grand Exchange, so this tool makes it easy to plug in live prices and quickly compare crops. If you want to decide between Ranarr, Snapdragon, Toadflax, Torstol, or any custom crop, you can do it in seconds.

How to use the calculator

1) Pick a crop preset (or custom)

Presets fill in sample values so you can start quickly. Since market prices move, always replace them with current numbers for best accuracy.

2) Set your patch count and survival rate

Most established accounts run multiple herb patches in one route. Survival rate represents how often patches make it to harvest. If your setup includes strong disease protection and compost usage, you can use a high value.

3) Add your expected yield per patch

Yield depends on Farming level, compost, equipment, and RNG. If you track your runs, use your personal average to get realistic forecasts.

4) Review net profit and daily totals

The result panel shows net gp after seed and compost costs, plus optional GE tax impact. You also get XP totals and gp/minute to compare methods.

Key factors that change herb run profit

• Seed price volatility: often the biggest expense per patch.
• Herb sale price: final output value can swing heavily during peak times.
• Yield per patch: even +0.5 average yield can significantly increase long-term profit.
• Compost quality: better compost usually improves consistency.
• Travel speed: faster routes improve gp/hour and fit more runs per day.
• Patch unlocks: additional herb patches increase total output with minimal extra planning.

Example farming route calculation

Suppose you run 9 patches, average 7 herbs per successful patch, and have a 92% survival rate. The calculator converts that into expected harvested herbs, then subtracts seed and compost costs to give net profit. Multiply by your runs per day and you have a practical daily income projection.

This approach is more reliable than “best-case” assumptions because it includes failures and costs. Over hundreds of runs, realistic averages matter far more than lucky outliers.

Tips to improve your OSRS farming results

Track your own averages

Keep a simple log for 20–50 runs. Enter your true average yield and real prices into this calculator. Personal data beats generic guides every time.

Buy inputs at better times

If you bulk-buy seeds and compost during favorable pricing windows, long-term margins improve. Even small savings per patch compound quickly.

Optimize run timing

Consistency matters. A short, repeatable route often beats an “optimal” route you rarely complete. Set reminders and stick to a schedule.

Adjust when markets shift

Don’t lock into one herb forever. Recheck profitability frequently and switch crops when margins tighten.

Common mistakes players make

• Ignoring GE tax and overestimating take-home profit.
• Using outdated seed/herb prices from old videos or forum posts.
• Assuming perfect survival and perfect yield on every run.
• Forgetting to include compost costs in net calculations.
• Comparing methods without accounting for time per run.

FAQ

Is this only for herbs?

No. You can use Custom Values for any Farming activity where you know cost, output price, yield, and success rate.

Why is my profit negative?

Usually seeds are too expensive relative to your herb sale price and yield. Try updating prices, changing crop, or improving your expected yield.

How accurate is this calculator?

It is a forecasting tool based on your inputs. Accuracy improves when you use real-time prices and your personal run data.

Final thoughts

A solid OSRS farming calculator removes guesswork from herb runs. Use it before buying supplies, after market swings, or whenever you change route efficiency. Small optimizations in yield, cost control, and run consistency can produce major gains over time.
