eve planetary interaction calculator

If you play EVE Online, you already know Planetary Interaction (PI) can be steady passive income—or a frustrating spreadsheet trap. This calculator helps you quickly estimate whether a colony chain is worth running before you spend time on setup and hauling. Instead of guessing, you can compare scenarios and make smarter ISK decisions.

What this EVE PI calculator does

This tool focuses on practical profit forecasting. It calculates how much you produce each day, your gross revenue, your total costs, and your net profit over daily and monthly timeframes. It also includes a break-even price and a setup payback estimate.

• Works for P1, P2, P3, or P4 workflows.
• Supports single-planet and multi-planet operations.
• Includes tax and logistics drag that many pilots forget.
• Useful for highsec, lowsec, nullsec, and wormhole PI planning.

How to use it effectively

1) Start with realistic throughput

Enter your Units Produced Per Hour from your current layout, not a perfect-theory number. Real colonies lose uptime due to extractor resets, route mistakes, and delayed pickups.

2) Apply uptime honestly

If your colonies sit idle overnight or during workdays, drop uptime below 100%. A pilot with irregular login windows may use 70–90%. This one field usually has a bigger impact than trying to optimize a few percent in tax.

3) Separate variable and fixed costs

Costs like input materials and taxes scale with volume, while hauling often feels fixed per day or per trip. Breaking these apart gives a much clearer picture of whether scaling to more planets actually improves margins.

4) Compare against alternatives

Once you get a net monthly ISK estimate, compare it to other activities you could run with the same time: station trading, abyssals, reactions, or industry. PI shines when it fits your schedule and location advantages.

Input reference (quick definitions)

• Units Produced Per Hour: Total output rate from your current chain.
• Uptime %: Percentage of time your chain is actively producing.
• Sell Price Per Unit: Expected average price after realistic market behavior.
• Input Cost Per Unit: What you pay for feedstock if not fully self-sourced.
• Import/Export Tax Per Unit: Effective customs burden per unit moved.
• Number of Planets: How many planets run a similar production profile.
• Hauling Cost Per Day: Fuel, collateral risk, courier fees, or time-value estimate.
• Initial Setup Cost: Command centers, launchpads, links, and startup inventory.

Worked example: evaluating a PI setup

Suppose your chain outputs 90 units/hour of a P2 item, runs at 92% uptime, and sells around 9,200 ISK/unit. You buy some inputs for 3,100 ISK/unit, pay 350 ISK combined import/export tax, run 4 similar planets, and estimate 2,000,000 ISK/day in hauling overhead.

With those values, you can quickly see whether the daily net beats your target income. If margins are thin, try adjusting only one variable at a time: higher sell region, better POCO rates, tighter hauling cycle, or different commodity. The strongest improvements usually come from better market selection and lower effective tax, not from tiny layout tweaks.

Improving PI profits in New Eden

Reduce tax pressure

Customs tax can erase margins, especially on lower-tier goods. Whenever possible, operate where POCO rates are favorable, and avoid unnecessary import/export loops between planets.

Shorten your logistics chain

The more jumps and transfers you add, the more hidden cost you introduce. Consolidate where sensible, and align pickup schedules with your other routes to reduce dead-time.

Use market discipline

Don’t value output at last traded spike prices. Use conservative averages and expected turnover speed. A slower but reliable sell strategy often outperforms optimistic assumptions.

Track downtime and bottlenecks

Most PI inefficiency comes from idle extractors, clogged storage, or broken routes. Set reminders for reset windows and audit your colonies after every major layout change.

Common mistakes this calculator helps expose

• Ignoring taxes and assuming gross equals profit.
• Using 100% uptime despite inconsistent login cadence.
• Not pricing personal hauling time as a real cost.
• Scaling planet count without checking whether margins remain healthy.
• Underestimating payback time on expensive setup choices.

FAQ

Is this calculator only for one specific PI tier?

No. It is tier-agnostic. You can use it for P1 through P4, as long as your unit rate and costs are entered consistently.

Should I use Jita price or local hub price?

Use the price you can reliably realize where you actually sell. Convenience often matters more than headline peak price.

Can I include risk from PvP losses?

Yes. Add an expected daily risk premium into hauling cost to make projections more realistic for dangerous routes.

How often should I re-run the numbers?

At minimum once per week, and always after tax changes, major market shifts, or when moving operations to a new region. PI is stable income only if your assumptions stay current.
