These NATO Nations Spend the Most on Defense – Is America Still #1?

The North Atlantic Treaty Organization (NATO) operates as the largest military alliance in the world, namely based out of Europe and North America. With this consortium of nations comes an impressive collective military budget that goes towards funding all the assets, operations, and troops within the alliance. In fact, some of the largest national military budgets in the world contribute to the NATO alliance. Here, 24/7 Wall St. is taking a closer look at the NATO countries with the largest military budgets.

To determine the NATO countries with the largest military defense budgets, 24/7 Wall St. reviewed the 2025 Military Strength Ranking from Global Firepower, an annually updated defense-related statistics website with information on 145 countries. Global Firepower ranked 145 countries based on their PowerIndex, a composite of over 60 measures in categories such as military might, financials, logistical capability, and geography. The smaller the PowerIndex value the more powerful a nation’s theoretical conventional fighting capability is. We ranked these countries based on their military defense budget. We also included supplemental information regarding purchasing power parity, foreign exchange/gold reserves, external debt, a composition of military assets, as well as the overall military strength score.

Here is a look at the countries with the largest defense budgets in NATO:
