What does the Last War Research Calculator cover?

It covers all Tech Center research trees with remaining Iron, Food, Gold, and Valor costs, including Development, Economy, Squad trees, Special Forces (Unit X / T10), and troop mastery trees.

How do prerequisites work in the Research Calculator?

When you set a Want level, required prerequisites are auto-included in the plan and cost totals so you can see the full remaining path, not only the node you selected.

Can I calculate remaining costs from my current research levels?

Yes. Enter Now and Want levels for each node, or use Remaining mode to calculate only the upgrades you still need. You can also apply a research cost reduction percentage.
