l2 manor calculator

How this L2 manor calculator helps

The manor system in Lineage 2 can be one of the most stable adena sources, but only when your numbers are solid. This calculator gives you a fast way to estimate expected crop yield, gross revenue, taxes, total costs, and final net profit. Instead of guessing, you can make data-driven choices before spending your adena.

What each input means

Seeds Planted

The total number of seeds you buy and use in your farming session. More seeds increase both your potential revenue and your risk if prices are poor.

Seed Price

Your effective cost per seed in adena. Even a small increase here can destroy margins on large runs, so track this carefully.

Crops per Successful Seed

Average crop output from each seed that succeeds. This can vary by server files and configuration, so use realistic observed values from your own farming logs.

Harvest Success Rate

The percentage of seeds you expect to successfully harvest. This captures real-world performance and keeps your forecast conservative.

Crop Price and Tax

Crop selling price defines your gross income, while castle tax (or any equivalent cut) reduces what you actually keep. Both values can change frequently and should be updated often.

Extra Costs

Include teleport fees, consumables, soulshots/spiritshots, and other overhead. Ignoring these “small” costs is a common reason players overestimate profit.

Formula used

• Expected Crops = Seeds Planted × Success Rate × Crops per Successful Seed
• Gross Revenue = Expected Crops × Crop Price
• Tax Amount = Gross Revenue × Tax Rate
• Seed Investment = Seeds Planted × Seed Price
• Net Profit = Gross Revenue − Tax Amount − Seed Investment − Extra Costs
• ROI = Net Profit ÷ (Seed Investment + Extra Costs)

Quick example

Using the default values in the calculator:

• 1,000 seeds at 300 adena each
• 75% success rate
• 1.2 crops per successful seed
• 700 adena per crop
• 10% tax and 20,000 extra costs

The result shows a strong positive net return. This is exactly the kind of scenario where scaling up can make sense—assuming your market can absorb the crop volume without collapsing price.

Tips to maximize manor profit

• Track real average success rate over multiple sessions.
• Recalculate every time seed or crop prices move.
• Don’t ignore tax differences between castles and periods.
• Use break-even price as your hard floor.
• Spread risk by not committing all adena to one crop type.

Common mistakes players make

• Calculating revenue on ideal outcomes instead of expected outcomes.
• Ignoring hidden costs (consumables, travel, and failures).
• Treating one lucky run as normal long-term performance.
• Overfarming low-demand crops and crashing local market value.

Final note

Private servers and chronicle versions can tweak manor mechanics significantly. Use this tool as a flexible financial framework, then tune values to your server reality. If you keep your assumptions accurate, this calculator can become a reliable part of your daily adena strategy.
