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.

How to use the Fire Crystal calculator
Pick a building and its current FC level
Select each building (Furnace, troop camps, Embassy, Infirmary…) and its current Fire Crystal level. If a building is still below Furnace 30, use the Buildings calculator instead.
Set your target FC level
Choose the FC level you want to reach, up to FC10. The calculator adds up every step in between, for one building or several at once.
Read the FC and RFC totals
See the total Fire Crystals and Refined Fire Crystals required, plus the SvS points the upgrades will award.
Time it for Fire Crystal day
Compare the cost to your stock and schedule the upgrades for the Fire Crystal day of SvS to turn the spend into peak event scoring.
How Fire Crystal SvS points are calculated
Each Fire Crystal upgrade awards State vs State points based on the materials it consumes. As a rule of thumb: SvS points ≈ Fire Crystals × 2,000 + Refined Fire Crystals × 30,000, plus a bonus for the construction speed-ups the upgrade represents.
Example: an upgrade costing 500 FC and 40 RFC gives roughly 500 × 2,000 + 40 × 30,000 = 1,000,000 + 1,200,000 = 2,200,000 SvS points before the speed-up bonus. Because each Refined Fire Crystal is worth about 15× a raw Fire Crystal in points, upgrades that lean on RFC produce the biggest spikes on Fire Crystal day.

Report a bug / Feedback →Frequently asked questions
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.
Which buildings switch to Fire Crystals?
The Furnace, Embassy, Command Center, Infirmary, the three troop camps (Infantry, Lancer, Marksman) and the War Academy building all upgrade with Fire Crystals from FC1 to FC10. The calculator totals every building you plan to raise.
How do I maximise SvS points on Fire Crystal day?
Stockpile Fire Crystals and Refined Fire Crystals, then finish the upgrades during the Fire Crystal day of State vs State so the points land inside the scoring window. Refined-heavy upgrades give the biggest spikes, so plan those first with the calculator.
