Satisfactory Iron Ingot Calculator
One Smelter makes 30 Iron Ingots/min from 30 Iron Ore/min at 4 MW. For 65/min, use 3 Smelters at approximately 72.2222% clock each, consuming 65 Iron Ore/min.
Calculator power uses fractional machines at 100% clock: 8.667 MW for the standard 65/min recipe (rounded in the summary). The whole-building plan uses 3 Smelters at approximately 72.2222% for 7.805 MW. Both exclude extraction and pumps.

Which iron ingot recipe should I use?
- For ore-only simplicity: Standard Iron Ingot uses only iron ore and 0.133 MW per ingot/min at full clock.
Available during Onboarding. Recipe details.
- If limestone is available: Basic Iron Ingot halves iron ore use, adding 0.8 Limestone per ingot. Basic is an alternate recipe, despite its name.
Hard Drive research after Tier 3 — Basic Steel Production. Recipe details and Hard Drive unlock.
- If copper is available: Iron Alloy Ingot uses 0.533 iron ore + 0.133 Copper Ore per ingot. Check that this copper is spare before diverting it from other lines.
Hard Drive research after Tier 3 — Basic Steel Production. Recipe details and Hard Drive unlock.
- If water infrastructure is ready: Pure Iron Ingot makes 65 ingots/min in one Refinery at 100% clock: 35 Iron Ore/min + 20 m³ Water/min, 30 MW before extraction. It saves 46.15% of the ore.
Hard Drive research after Tier 5 — Oil Processing. Recipe details and Hard Drive unlock.
- If sulfur and acid infrastructure are ready: Leached Iron Ingot halves iron ore use but needs Sulfuric Acid. Standard acid support adds sulfur, water and another Refinery; chain power is 0.36 MW per ingot/min at full-clock equivalents.
Hard Drive research after Tier 7 — Control System Development. Recipe details and Hard Drive unlock.
Alternate prerequisites: official recipe reference, checked 2026-10-29. Milestones make an alternate eligible; you still need to select it through Hard Drive research. See the alternate-recipe tier list for cross-product resource comparisons.

Buildings and Normal-node miners for common targets
Build the whole production counts shown and set each group to its listed clock. The number in parentheses is the fractional building equivalent at full clock. Supporting production is included; water extractors are separate.
Miner counts are whole nodes at 100% clock, listed in Miner Mk.1 / Miner Mk.2 / Miner Mk.3 order. Their Normal-node capacities are 60 / 120 / 240 items/min. Round each resource up separately and throttle to demand. Upgrade belts to carry each miner’s output; use the miner calculator for extraction power and belt limits, and production ratios guide for downstream chains.

Power at the listed clocks uses the game’s exponent of 1.321929: buildings × base MW × (clock / 100)1.321929. The calculator above uses fractional full-clock equivalents. Displayed clocks and rates are rounded; use the exact target rate when setting production.
Iron Ingot questions
How many smelters for 65 iron ingots?
Use 3 Smelters at approximately 72.2222% clock each for 65 Iron Ingots/min, or 2 at approximately 108.3333% with Power Shards. The standard recipe consumes 65 Iron Ore/min. The 3-building underclocked setup draws about 7.805 MW for smelting; mining is additional.
Is Pure Iron Ingot better than the standard recipe?
Pure Iron Ingot uses 0.538 Iron Ore per ingot instead of 1, saving 46.15% of the iron ore, but adds 0.308 m³ Water per ingot. One Refinery makes 65 ingots/min at 30 MW. At full clock, recipe power is 0.462 versus 0.133 MW per ingot/min for the standard recipe. Choose it when conserving iron ore matters more than power and water infrastructure.
How much power does iron ingot production use?
At full clock, the standard recipe uses 4 MW per Smelter, or 0.133 MW per ingot/min. For 65/min, the calculator’s fractional full-clock estimate is 8.667 MW; 3 evenly underclocked Smelters use about 7.805 MW. Alternate recipe machines range from 16 to 30 MW each. Leached Iron Ingot also needs 0.06 MW per ingot/min for standard Sulfuric Acid production at full-clock equivalents. Mining, water extraction and pumps are additional throughout.
