Choose research by its actual benefit.

Start with a capability

Pick one result you will actually use: a colony ship, additional fleet capacity, a particular ship, or a production improvement. Research levels are means to those results. A long technology list can tempt you to buy one of everything without ever completing a useful chain.

Open the target’s technology tree and write down every unmet prerequisite. Include building levels as well as research levels. Then order them so each requirement becomes available before you need it. Keep this plan short enough to finish; a list of every late-game technology is not a near-term plan.

Classify the benefit

Classic research applies across the account. Lifeform technology levels are developed separately on planets, but their applicable active bonuses can contribute across the account. A Research Lab enables technologies and influences research duration. The classic system runs one normal research at a time; a queue schedules work rather than creating parallel classic research. Check current restrictions around laboratory upgrades before starting a long technology.

Research costs and prerequisites

1. Write the target, its prerequisites and the resources needed for each missing step. Use current costs from your account.
2. Estimate when the slowest resource will be ready. Account for planned spending elsewhere before promising a start time.
3. Check the lab requirement and displayed duration on the planet where you will start. Compare a lab upgrade only if its total delay and cost are justified.
4. Schedule any lab work before the long research begins, after checking the current queue restrictions.
5. Reserve resources for using the unlock. A newly available ship is not helpful if no budget remains to build it or fuel it.

Buy time deliberately

An expensive lab investment may make sense when you have a sustained research program. It may be wasteful when one affordable unlock is the only immediate objective. Compare the completion date of the entire plan, including the time to fund and construct the lab, rather than only the shorter research timer.

Later, Intergalactic Research Network can combine eligible laboratories; do not assume every lab you own contributes automatically. Read its current description and the technology’s lab requirement before distributing upgrades. The right question is which additional lab actually shortens the research you intend to run.

Test the unlocked capability

When research finishes, confirm that the intended action is now available. Recalculate relevant fleet times after drive research; an old fleetsave timetable may no longer fit. If you bought mission capacity, try the additional mission during a session you can supervise. If you expected a production gain, compare the resource screen before and after under the same settings.

Record what the upgrade changed and choose the next bottleneck. Do not immediately buy another level by habit. A useful research plan is revised as the account gains colonies, changes play style or loses the time needed to use an active fleet.

The recurring benefits worth comparing

These are the classic baseline effects, before applicable class, officer, item and Lifeform changes. Source: staff research reference and maintained research reference. Fleet-specific drive thresholds and combat research belong with the fleet reference.

Astrophysics: buy the next threshold

The formulas are 1 + floor((A+1)/2) total planets and floor(sqrt(A)) base expedition slots. Additional class, item or other account entitlements are separate. Expedition fleets still consume normal fleet capacity, so an expedition slot alone does not guarantee another launch.

Classic target-level costs use bases 4,000 M / 8,000 C / 4,000 D, factor 1.75, with each component rounded to the nearest 100. Sum each remaining level separately, then apply only validated applicable cost reductions. The Astrophysics reference gives this rounding explicitly.

For Astrophysics 17→19, level 18 costs 54,163,500 M / 108,327,000 C / 54,163,500 D. Level 19 costs 94,786,100 M / 189,572,300 C / 94,786,100 D. Total: 148,949,600 M / 297,899,300 C / 148,949,600 D before reductions. This buys the next research-only planet capacity, not a developed planet. Crystal is not exactly twice the already-rounded Metal total because each component is rounded independently.

Plasma: the percentage is of the base

Use the applicable mine base, including the appropriate position/economy treatment, rather than multiplying the final total income by the advertised percentage. Additional modifier interactions need their own model; the resource screen is the check for a real account.

Suppose the relevant aggregate hourly bases are 1,000,000 M, 500,000 C and 300,000 D. One Plasma level adds 10,000 M, 3,300 C and 990 D per hour in this unmodified example. At M1/C1.5/D3, the gain is 430,080 metal-equivalent per day.

Classic Plasma level 15 costs 32,768,000 M, 65,536,000 C and 16,384,000 D before reductions. At those weights its cost is 180,224,000 and simple payback about 419.05 days. This is deliberately an illustration of the calculation, not a recommendation for level 15. More planets or higher mines improve the return; a cheaper local upgrade can still win now. If Plasma is not yet unlocked, include the missing prerequisites. The classic prerequisites are Research Lab 4, Energy 8, Laser 10 and Ion 5.

Laboratories and IRN: eligibility matters

IRN level N can combine the starting laboratory with up to N additional eligible laboratories. Each contributing lab must meet the minimum lab requirement for the technology being researched. It does not divide one research into parallel independent completions, and it does not let an insufficient starting lab ignore the technology tree.

With laboratories 12, 10 and 8 and IRN 2, a technology requiring Lab 8 can use an effective level of 30. A technology requiring Lab 10 can use only 22. Raising IRN again does not help either example if there is no further eligible lab. Conversely, bringing a nearby lab across an eligibility threshold may contribute its whole level to the network, not just the one new level.

Before modifiers, research time in hours is (Metal cost + Crystal cost) / [1,000 × (1 + effective lab level) × total research speed]. Deuterium is part of the resource price but not this baseline time numerator. For an unchanged research and other factors, increasing effective lab 22→30 changes the timer by 23/31, about 25.81% shorter.

Use the universe's total advertised research multiplier. A server listed as ×10 economy and ×20 research means ×20 in this equation, not ×200. Class, officer, Lifeform and other time modifiers require the actual applicable calculation; compare the final displayed duration before starting. See the October 2026 settings explanation.

Time saved is valuable only when the program uses it

Compare completion dates including funding, laboratory construction and any queue restrictions. Eight hours of lab preparation followed by a fourteen-hour technology completes in twenty-two hours, later than starting its present twenty-hour timer immediately. The lab may still pay off over a longer research program.

For expansion, count the even level that lies between today's odd Astrophysics level and the next colony. For an extra expedition slot, check the square-number threshold and whether normal fleet slots, ships and your schedule can use it. For drive upgrades, recheck future launch timings and fuel rather than assuming your old fleetsave settings still fit.
