The Warhammer 40K Army Points Calculator keeps a running tally as you build a matched-play list. Add each unit with its base cost and any upgrade points, choose your game size, and the total tells you instantly whether the list fits inside Incursion, Strike Force, or Onslaught limits.
How it works
Matched play in 10th edition assigns every unit a points value, and enhancements or wargear can add more. Your army total is simply the sum of every unit’s base points plus its upgrade points. The tool adds those two fields per line and totals all lines.
The standard game sizes are fixed budgets:
Incursion 1,000 pts (~1–2 hours playtime)
Strike Force 2,000 pts (~2.5–3 hours; standard tournament size)
Onslaught 3,000 pts (~4+ hours; large battles)Pick one and the calculator subtracts your total from it to show points remaining, flagging the list in red the moment you exceed the cap.
Understanding points in 10th edition
Warhammer 40K 10th edition overhauled how points work. Every unit has a base cost that covers the whole unit at its listed size, and most wargear is free — no per-model weapon costs to track individually. What does add points are: enhancements (upgrades to a Character), additional models beyond the base unit size where the datasheet allows, and any specifically costed wargear options your army’s points list includes.
Points are updated through balance dataslates published throughout the year between major releases, so the cost of a unit today may differ from what it was at codex launch. Always pull the current points from the official points list published by Games Workshop for the current season.
What the calculator covers — and what it does not
The tool tracks your points budget, which is the single most commonly needed check at the list-building stage. What you still need to verify separately:
- Detachment rules — each detachment has its own composition requirements on the number of each unit type.
- The Rule of Three — you generally cannot include more than three copies of the same datasheet in a list.
- Unit size limits — some datasheets cap the maximum size of a unit even if you have points to spend.
- Character attachment rules — which Characters can lead which units.
Tips and notes
- Points costs change with balance dataslates — always use the current season’s official document, not a cached copy from a list-building app that may not have updated yet.
- A competitive Strike Force list typically leaves fewer than 10 points unspent; any more usually means you are missing an upgrade or under-filling a unit.
- Save or screenshot your list before closing the tab — the calculator resets on reload, and nothing is saved to a server.
