Last War Research Calculator

Research costs increase with each level. This calculator uses a 1.15× compounding growth curve per level for resource costs and a 1.12× curve for time, which approximates the scaling most players observe — exact values can vary slightly by server and game version.

Research typically requires Food, Wood, Iron, and Silver in varying amounts depending on the research category and level. This calculator breaks down exactly how much of each you'll need from your current level to your target level.

Military research boosts troop attack, defense, HP, and capacity. Development research improves construction, resource production, and gathering speed. Defense research strengthens your base's walls and turrets. Special research covers hero, VIP, and alliance-related bonuses.

Use the Speedup Calculator section below the main results — enter how many 1-hour, 8-hour, and 24-hour speedup items you have, and it will tell you instantly whether that's enough to finish your selected research instantly, and how much more (or how much extra) you have.

That depends on your priorities. Rushing is best for time-limited events or catching up to your alliance, while waiting naturally is more resource-efficient if you're not in a hurry. This calculator helps you see exactly how many speedups a research level actually costs so you can decide.

Last War: Survival Game updates its research costs periodically, and exact numbers can differ slightly between servers. This calculator uses community-verified growth curves to give you a very close estimate for planning purposes.
