Whiteout Survival Furnace requirements calculator
Whiteout Survival Furnace requirements, worked out for you. Pick your Furnace level and target, and the calculator follows every prerequisite, adds up Meat, Wood, Coal, Iron and Fire Crystals, and gives you a build order.
1. Your Furnace
Use the Construction Speed figure from your in-game bonus stats (research, VIP, chief gear and other boosts all add to it). Base time is divided by (1 + bonus), the way speed bonuses work in the game.
2. Buildings already above the minimum (optional)
We assume each building is at the lowest level your Furnace needs. If you have upgraded some further, set them here and the plan shrinks.

Why the Furnace is never just the Furnace
Every Furnace level needs other buildings first. From Furnace 11 onward it is always the Embassy one level below, plus one more building that rotates between the three troop camps and the Research Center. Those buildings have their own requirements too. The calculator follows the whole chain, the way the game does, so the total includes every Embassy, camp and Research Center upgrade you need on the way, in an order that works.
The numbers are big. Going from a new account to Furnace 30, with the minimum of everything else, takes about 2.50B Meat, 2.50B Wood, 502.8M Coal and 125.8M Iron, and 407d 18h of building time with no speed bonus. Going on from Furnace 30 to FC5 adds 10,370 Fire Crystals and 533d 10h more.
Fire Crystal levels
After Furnace 30, each Fire Crystal (FC) level is split into five upgrades: four steps (shown as 30 · 1/4 and so on) and the FC level itself. Each step costs Fire Crystals, and from the first step after FC 5 the Furnace also needs Refined Fire Crystals. FC levels only unlock as your state gets older: see the state timeline for when FC5, FC8 and FC10 open.
Tips to get there faster
- Never let the builder sit idle. Start the next upgrade before you log off, even a short one.
- Save construction speedups for the Furnace. Its upgrades are the longest in the chain, and many events give points for using speedups.
- Upgrade prerequisites during events. Use the build order above so requirements are done before the Furnace timer finishes.
- Raise construction speed first. Research and boosts that add construction speed pay back on every later upgrade.
