RoFront Infrastructure Payback & ROI Calculator

Factory trucks hit diminishing returns above 5 units, while Cities reliably grant +25,000 troop cap. Calculate actual payback seconds before funding new construction.

1. First-Screen Verdict & Rule of Thumb

The 5-Factory Hard Rule: In RoFront, commercial factory truck dispatches cap mathematically at 5% per game tick between 5 and 10 factories. If you own fewer than 5 factories and borders are quiet, build factories for ~180s payback. If you own 5 or more factories, or borders touch a hostile sovereign, stop building industry immediately: invest in Cities (+25K Troop Cap) or deploy a 50K Gold Defense Post (5x casualty shield).

0-4 FactoriesHigh ROI (~180 Gold/s delta). Prioritize factory expansion.

5-9 FactoriesDiminishing returns. Only expand if domestic road grid is unclogged.

10+ FactoriesZero ROI ceiling (5%/tick cap). Additional factories waste gold.

Optimal Tactical Recommendation

Upgrade Municipal City (+25K Troop Cap)

Diminishing factory returns make expanding army capacity safer for defending your growing borders.

Next City Cost: 500,000 G

Next Factory Cost: 1,000,000 G

Next Factory Payback: ~5556s

Defense Post Cost: 50,000 G

Action Plan	Cost	Primary Gain	Affordable Now
Build City	500,000 G	+25,000 Troop Capacity	NO
Build Factory	1,000,000 G	+180 Gold/sec	NO
Build Defense Post	50,000 G	5x Enemy Casualty Barrier	YES

2. In-Game Input Reference & Telemetry Locations

Current Gold Balance:Look at the top-right corner HUD (Gold metric). Observed values range from 1,000 G at match spawn to 10M+ in nuclear endgame.

Municipal Cities & Factories Count:Open the bottom-left Build Menu or check the Nation Overview panel to tally deployed structures.

Operational Stance:Select Border Conflict if the right-hand panel displays TIP: You are under attack!. Defensive survival always overrides industrial ROI.

Tier Escalation Triggers:Costs jump automatically from 125K to 250K, 500K, and 1,000,000 G as cumulative structures are completed.

3. Calculation Methodology & Operational Boundaries

This optimizer is calibrated directly against Open Front calculus dispatch formulas and verified RoFront gameplay telemetry (CHALLS 00:15-08:05):

Baseline passive income: 1,000 Gold/sec (10 ticks/sec at standard match multiplier).
Truck dispatch curve: P = 1 - e^(-0.1 * N), capping at 5.0% probability per tick above 10 factories.
Municipal city cap expansion: Fixed +25,000 troop capacity per city level.

Model Limitation: Calculations assume uninterrupted domestic road routes. If hostile warships sever marine trade lines or enemy divisions cut internal road grids, actual gold yields will drop below calculated estimates.
