Magic: The Gathering Mana Curve Calculator
Our Warhammer 40k Army Points Calculator
Point management separates a well-crafted roster from one that gets you turned away at the door. In Warhammer 40,000, where every point matters and the rules shift with every new dataslate having a reliable way to track your army's composition isn't a luxury it's a necessity.
This calculator was built from the ground up to handle the specific demands of 10th Edition list construction, running entirely in your browser with no downloads or account required.
The Ultimate Warhammer 40k 10th Edition List Builder
10th Edition streamlined how units are costed, moving away from the older per-model pricing toward flat unit costs.
Straightforward on the surface but once you layer in Enhancements, Detachment rules and the Rule of Three, the margin for error grows fast.
This tool functions as a complete roster-building environment no more cross referencing dog eared Field Manuals or hunting down the latest PDF just to confirm whether your list sits under the cap.
Why Use a Dedicated 40k Points Tracker?
Spreadsheets and notebooks work until they don't. A misread Enhancement cost or a forgotten upgrade tally can quietly push your list over the legal limit something you'd rather catch at home than at a tournament table.
This calculator handles the arithmetic automatically, keeps a running model count, and validates your Warlord selection in real time, so the only thing you're focused on is the strategy behind the list.
Key Features
Flat Cost and Per-Model Flexibility
The tool supports both Flat Unit Costs, which reflect how standard 10th Edition armies are priced, and Points Per Model calculations for players running Horus Heresy campaigns or custom narrative formats. Switch between modes depending on the game you're building for.
Live Rule of Three Monitoring
Grand Tournament play enforces a hard cap of three duplicate datasheets per army, with exceptions carved out for Battleline and Dedicated Transport units.
As you add units the calculator watches your roster in real time. Stack a fourth copy of the same datasheet whether that's Terminators, Crisis Suits, or anything else outside the exempt categories and you'll get an immediate visual alert before the problem becomes a submission error.
Warlord and Detachment Fields
Designating a Warlord is a basic requirement in 10th Edition and this tool makes it impossible to forget. Mark any Character as your Warlord and the tool flags them clearly within your list.
A separate Detachment field lets you log your chosen formation whether that's a Gladius Task Force, Invasion Fleet, Cult of Magic or any other keeping your list organized from top to bottom.
Per-Unit Wargear and Enhancement Costs
Leaving Enhancement costs out of a unit's total is one of the most common list-building oversights in competitive play. The wargear system here lets you attach upgrades directly to individual units. Those costs fold into that unit's point total automatically so you always know exactly where each point in your list is going.
How to Build a Competitive Warhammer 40k List
Step 1 — Anchor Your List with Battleline
Battleline units are the foundation of any competitive army. Because they fall outside the Rule of Three restriction allowing up to six of the same datasheet they give you the flexibility to build a durable objective holding core.
Use the Battleline toggle when adding these units so the calculator categorizes them correctly and doesn't flag them as violations.
Step 2 — Lock In Your Warlord
Pick the Character leading your force and activate the Warlord toggle on that unit. The tool highlights your Warlord in gold throughout the list making them easy to spot in both the builder and any exported version of your roster.
Step 3 — Add Your Combat Units
With your core in place, start adding the units carrying your offensive weight. The duplicate unit feature lets you clone an existing entry — point values, wargear, and all without re-entering data manually. This is especially useful for horde-style factions like Orks or Tyranids where you're fielding several near-identical squads.
Step 4 — Fine-Tune with the Dashboard
The sticky dashboard at the top of the page tracks your running total and remaining points against your chosen limit in real time.
If you land at 1,985 points with 15 remaining you can immediately see whether that gap fits a cheap Enhancement or a small unit addition without scrolling through your entire list to recount.
Sharing Your List: Reddit and Discord Export
Getting feedback from your gaming group or competitive community means sharing your list in a readable format. Most builders spit out raw text that requires cleanup before it's presentable.
The Markdown Export function produces a clean, properly formatted list ready to drop directly into Reddit's r/WarhammerCompetitive or any Discord server.
The output includes your faction name, points total versus your chosen limit, a full unit-by-unit breakdown with wargear and clear Warlord identification no reformatting needed.
Frequently Asked Questions
Does the calculator stay current with the latest balance dataslate?
Because you control the point values you enter or use the flat cost system directly you can update your list the moment Games Workshop publishes new figures. You're not dependent on a developer update cycle to stay current.
Can I come back to my list after closing the browser?
Yes. Your army data is stored in your browser's local storage, so it persists between sessions even if you restart your device. The one exception: clearing your browser cache will erase any saved lists.
How exactly does the Rule of Three enforcement work?
The tool tracks the names of units in your roster. Any time the same name appears more than three times without the Battleline tag applied, the dashboard flags it as a violation. Battleline units are exempt and can appear up to six times without triggering a warning.
What point limits does the tool support?
The point cap is fully adjustable. Set it to 500 for Combat Patrol, 1,000 for an Incursion game, 2,000 for Strike Force or push it as high as you need for an Apocalypse-scale battle. The progress bar and remaining points counter recalibrate automatically to whatever limit you choose.
