Method and precision · Send a correction
Each miner supplies 480 items/min; each outlet needs at least Mk.4.
Clock labels are rounded to 1 decimal. Set each miner’s target output to 480 items/min to match the calculated rate; small in-game rounding differences can occur.
Count nodes of this purity that you can use for the same resource. Minimise power checks every feasible miner count within this limit; extra underclocked miners can save power. Node counts are limited per map.
MW is running miner power at the default ×1 power setting, excluding transport and processing.
One miner’s output & smelters
A Miner Mk.1 on a Normal node at 100% clock yields 60.0 /min. Purity multiplies the base rate (impure ×0.5, normal ×1, pure ×2) and clock speed scales it linearly.
Smelters per miner at 100% smelter clock: Iron Ore 2 · Copper Ore 2 · Caterium Ore 1.333 (default recipes, no amplification; fractional counts are full-clock equivalents).

Fewest miners vs no-overclock plans
Compare the fewest miners at ≤250% with the fewest at ≤100%. The no-overclock plan uses no shards and lowers power when it adds miners.
Cells show miner count × clock, output per miner, total MW and total shards. All miners use the row’s purity. More nodes and further underclocking may save power; use the planner with your available node count.

MW uses the default ×1 power setting. Every plan needs one node per miner of the same resource and purity; map availability can make a plan impractical. Small in-game output-rounding differences can occur.
How the target planner works
Output = base mining rate × purity × clock ÷ 100. Minimise miners divides the target by one miner’s capacity at your clock cap, rounds the count up, then gives all miners an equal clock. Minimise power compares every feasible count within your node limit using base MW × (clock ÷ 100)1.321929.
The power exponent is 1.321929, using the game export’s six-decimal precision. Power is calculated from unrounded clocks; these are calculated plans, not in-game measurements.
The selected Mk stays fixed; compare tiers with the dropdown. Clocks cannot fall below 1%. The minimum belt must carry the combined output, and every miner’s outlet must carry its own output before any splitters. For downstream machines, use the production calculator or production ratios guide.
Rate, power and belt inputs use the versioned game data above. See the mining calculation method and sources and clock and Power Shard rules.
Miner calculator FAQ
How much does a Miner Mk.1 produce in Satisfactory?
At 100% clock, a Miner Mk.1 produces 60 items per minute on a Normal node, 30 on Impure, and 120 on Pure. Mk.2 produces 120 on Normal and Mk.3 produces 240 on Normal.
How does node purity affect mining rate?
Purity multiplies the base rate: Impure ×0.5, Normal ×1, Pure ×2. Clock speed scales the result linearly on top of that.
How many smelters per miner?
Divide the miner’s ore output by one Smelter’s ore consumption. At 100% clock, the default recipes consume 30 Iron Ore/min, 30 Copper Ore/min, 45 Caterium Ore/min. A Pure Mk.3 at 100% supplies 480 ore/min: 16 Iron Ore Smelter equivalents, 16 Copper Ore Smelter equivalents, 10.667 Caterium Ore Smelter equivalents. Fractional counts are full-clock equivalents; round up the building count and underclock to match. These figures assume no amplification.
How do I change miner Mk in the calculator?
In “Plan for a target rate”, choose Miner Mk.1, Mk.2 or Mk.3 from “Unlocked miner Mk”. Every miner in that plan uses the selected tier. In the single-miner calculator, change the “Extractor” dropdown. Both tools recalculate when you change the selection.
How much does a pure node produce?
At 100% clock, a Pure node produces 120 items/min with Mk.1, 240 items/min with Mk.2, 480 items/min with Mk.3. At 250%, Pure Mk.3 reaches 1,200 items/min and requires a Mk.6 belt. The miner tier and clock determine the rate; purity alone does not.
