IronWhiteout Survival Fire Crystal Calculator
Once your Furnace reaches level 30, buildings upgrade with Fire Crystals (FC) and Refined Fire Crystals (RFC) instead of standard resources. This calculator totals the FC and RFC needed to take the Furnace, Embassy, Command Center, Infirmary, the three troop camps and the War Academy building from FC1 to FC10. Past level 30 the Furnace enters its Fire Crystal tiers — the stage many players call the Crystal Furnace.
Fire Crystal upgrades are expensive and award large amounts of SvS points. Planning the exact FC/RFC cost and SvS reward for each Crystal Furnace level lets you time upgrades around the Fire Crystal day and maximise event scoring.

Is the Crystal Furnace the same as the Furnace?
Yes. Once the Furnace passes level 30 it unlocks the Fire Crystal tiers (FC1–FC10), the stage many players call the Crystal Furnace. This calculator covers the exact Fire Crystal and Refined Fire Crystal cost of every Crystal Furnace level.
What is the difference between Fire Crystal and Refined Fire Crystal?
Fire Crystals (FC) are used for the early FC building levels, while Refined Fire Crystals (RFC) are required for higher levels. Both are summed separately by the calculator.
When do buildings start using Fire Crystals?
Buildings switch from standard resources to Fire Crystals once the Furnace hits level 30 and unlocks the FC1–FC10 tiers.
How many SvS points do Fire Crystal upgrades give?
FC upgrades award SvS points based on FC × 2,000 + RFC × 30,000 plus a speed-up component. The calculator estimates the total so you can plan the Fire Crystal SvS day.
Where do I get Fire Crystals in Whiteout Survival?
Fire Crystals come from Intel missions, the Arena shop, Castle Battle and events. Use the calculator to know how many to save before an upgrade.
