Fan app shows Warhammer 40k army points and real-world cost together

Warhammer players have long built lists in points and bought armies in cash, and 40k army makes that split impossible to ignore. The fan-made web app shows a roster’s points total and its real-world price together, which lands hard in a hobby where Games Workshop announced about a 4% price rise in August 2025, effective October 6, 2025, after also saying a separate 3.5% increase on miniatures and books helped offset about $8 million in US tariff costs in the six months ending November 2025.

That is the appeal of 40k army. Charles George Brown, a designer from Manchester, UK, started it as a solo project and later brought in two collaborators after sharing it on Reddit in early March. The tool lets you pick a faction, add units to a roster and watch the points and price climb together. For anyone weighing a new detachment, a fresh army, or even a single expensive unit, it turns list-building into something more immediate: two armies can be legal at the same points level and still land at dramatically different totals at checkout.

Brown said the toughest part was making the retail data trustworthy. Regional prices differ, kits often map to more than one in-game option, and not every box has a clean one-to-one relationship with a unit entry. That is exactly where a lot of hobby calculators fall apart, and exactly why this one feels more useful than a quick spreadsheet. Brown said the app now supports pricing data in seven currencies, which gives it reach beyond a single market and makes the sticker shock easy to compare across regions.

The idea also sits neatly alongside Games Workshop’s own tools. The official Warhammer 40,000 app, which launched on June 21, 2023, includes Battle Forge for Incursion, Strike Force and Onslaught army sizes, or 1,000, 2,000 and 3,000 points, but it does not translate those lists into money. Meanwhile, 40k.app keeps tracking points changes between rules updates, with version 4.0 released on March 4, 2026 and version 4.1 landing 21 days before the crawl. Together, the two fan tools capture the part of the hobby that Games Workshop leaves to players: the constant churn of points on one side and the actual cost of building the plastic on the other.

Brown also said he used AI as a development assistant for debugging, prototyping and repetitive coding tasks, which fits the project’s practical feel. This is a community answer to a very Warhammer problem, and it works because it deals in the numbers players already care about: points, pounds, dollars and euros, all in the same list.
