Lords Mobile research calculator

Nearly 300 researches across every tree. Pick one, set your current and target level, and see the resources, gold, time and might. Add several to plan a whole tree.

How to use the research calculator

  1. Choose a research tree, then the research.
  2. Set your current level and the level you want to reach.
  3. Tap Add to my research plan. Repeat to plan several researches or a whole tree.
  4. Enter your research speed bonus (%) and read the time, might, resources and Technolabes.

Example: Infantry Defense I, level 0 to 10

Maxing Infantry Defense I takes 301d 2h 38m at base speed, gives +2.14M might and costs 9.43M food, 15.72M stone, 15.72M timber, 11.53M ore, 53.44M gold and 17 Technolabes.

Questions

How is research time with boosts worked out?
Real time = base time ÷ (1 + your research speed bonus ÷ 100). With a 200% bonus, research takes a third of the base time.
Can I add up several researches at once?
Yes. Pick a research and level range, tap "Add to my research plan", and repeat. The totals cover everything in your plan.
Where do the numbers come from?
Each research's level-by-level cost, time and might from the Lords Mobile wiki. Researches the wiki hasn't fully documented are left out rather than guessed.
Does it include Archaic or Dueling Tomes?
Not yet. It shows resources, gold, time, might and the Technolabes needed to finish instantly.
