The RoWorld calculator tells you three things before you commit to a war in RoWorld [World PvP]: the troop cap your Cities give you, the full gold cost of the nuclear strike you are planning, and how long your current income needs to pay for it.

RoWorld is won by holding 80% of the map, and most late games are decided by who gets a Missile Silo and a Hydrogen Bomb first. Use the presets to price a first strike, a Hydrogen Bomb opener or a full MIRV, then adjust the numbers to match your match.

How the RoWorld Calculator Works

The RoWorld calculator uses the fixed numbers the game shows in its build menu. Every City raises your troop cap by 25,000. A nuclear strike needs one Missile Silo plus the price of each bomb. The tool adds those up, subtracts the gold you hold, and divides the gap by your gold per second.

Enter your Cities, your gold and your gold per second from the top bar.
Tick the Missile Silo box if you already own one.
Enter how many of each bomb you want to launch.
Enter the enemy troops on the border and tick the Defense Post box if one covers the target.
Read the gold gap, the wait time and whether your army can break the border.

RoWorld Nuke Costs and Blast Radius

Weapon	Gold cost	Blast	Notes
Missile Silo	1M	None	Required before any launch. Range is a circle around the silo
Atom Bomb	750K to 1M	30 tiles	Removes troops and structures, leaves fallout
Mega Nuke	2.5M	60 tiles	Unlocked in the Arsenal with Stars
Hydrogen Bomb	5M	100 tiles	Destroys everything in its impact area
MIRV	25M	Up to 350 warheads	Spread across one nation, and SAM Launchers cannot stop it

Every blast leaves green fallout. Fallout land does not count toward the 80% goal until someone reclaims it, so a Hydrogen Bomb on land you want to own costs you map share. Aim nukes at troop stacks, Cities and Missile Silos, not at empty ground.

RoWorld Building Costs: Cities, Ports and Factories

Building	Gold cost	What it does
City	125K to 1M	+25,000 troop cap, faster troop growth, connects to roads
Factory	125K to 1M	Road hub. Trucks pay gold at each stop on friendly routes
Port	250K to 1M	Trade ships for gold, builds Warships, staging point for invasions
Warship	250K to 750K	Hunts transports and trade ships, shells coasts
Defense Post	50K to 250K	Attackers within 30 tiles need 5x the troops and take 3x as long
SAM Launcher	1.5M to 3M	Shoots down bombs aimed within 70 tiles

Prices rise as you own more of a building, which is why each row is a range. A common build order is Cities first for troop cap, then Factories linked by roads, with Ports once you hold a coast. Beginner guides suggest stopping at about 10 Factories, because income stops keeping pace with the price after that.

RoWorld Calculator Worked Example

You own 6 Cities, hold 500K gold and earn 20K gold per second. You want a Hydrogen Bomb and do not own a silo. The RoWorld calculator shows a 6M gold cost, a 5.5M gap and about 4.6 minutes of saving. Your troop cap is 150,000. If the enemy has 50,000 troops behind a Defense Post, you need 250,000 troops to break through, so your army is 100,000 short. The answer is clear: bomb the Defense Post area first, or build four more Cities.

Tips for Using the RoWorld Calculator in a Match

Check the tooltip price before you build. The RoWorld calculator uses the top of each price range to stay safe.
Build a SAM Launcher before your rivals reach 5M gold. It covers 70 tiles.
Use the attack slider at 25% or 35% for probing attacks and keep the rest as defense.
An alliance closes a border, which frees troops, but betrayal halves the betrayed army and marks you as a traitor for 30 seconds.
Save the MIRV for the last large rival. At 25M it is five Hydrogen Bombs of gold.
