Economy Formulas

For players who want to optimize every credit. These formulas come directly from the game backend.

Trade Price Calculation

Prices use a logistic curve based on stock ratio.

stockRatio = currentStock / maxStock  (0.0 to 1.0)

L_range = L_max - L_min
normalized = (stockRatio * L_range + L_min)
price_multiplier = 1 / (1 + e^(-k * (normalized - L_midpoint)))

rawPrice = price_multiplier * BASE_PRICE[commodity]

Port type parameters:

Base commodity prices: Fuel 10 cr, Organics 15 cr, Equipment 25 cr (multiplied by the port-type factor)

Sell price: sellPrice = floor(buyPrice * (1 - spread))

Daily noise: Random variance per day where sigma is 0.5% for Low volatility, 1.0% for Medium, and 1.8% for High.

Price bands (hard limits):

Combat Power Formula

rawPower = basePower + (fighters × 0.8) + (shields × 1.2) + (torpedoes × 2.0)
effectivePower = rawPower × roleMultiplier × regionMultiplier × xpMultiplier
winProbability = attackerPower / (attackerPower + defenderPower)

Role multipliers vary slightly by ship class, ranging from 1.00 to roughly 1.10 for most ships.

Region bonuses:

• Federation-aligned ships defending in Fed Core: +10%
• Federation-aligned ships defending in Fed Space: +5%

Both sides receive a small random multiplier before resolution to prevent fully deterministic outcomes.

Loot Calculation

creditsLooted = min(loser.credits * 0.25, winner.tier.creditCap)
cargoLooted = floor(loser.totalCargo * 0.30)

Credit caps by ship tier:

Planet Production

factoryMultiplier = 1 + (0.15 * factoryLevel)
populationMultiplier = 0.2 + ((population / populationCap) * 0.8)

dailyFuel      = floor(80  * factoryMultiplier * populationMultiplier)
dailyOrganics  = floor(60  * factoryMultiplier * populationMultiplier)
dailyEquipment = floor(30  * factoryMultiplier * populationMultiplier)

Population growth (daily):

baseGrowth = 10
growthMultiplier = 1 + (0.10 * habitatLevel)
attrition = floor(population * 0.01)
growth = floor(baseGrowth * growthMultiplier - attrition)
newPopulation = min(population + growth, populationCap)

Structure Upgrade Costs

cost = floor(baseCost * multiplier^(currentLevel - 1))

Factory upgrade cost by level:

NPC Spawn Rates

Effective spawn rate per move equals baseRate multiplied by regionMultiplier multiplied by galaxyEncounterRate.

Base rates: Pirate 5%, Trader 3%, Patrol 2%

Key region multipliers:

Contraband Detection

baseThreshold = 0.75   (75% chance of detection)
withCloakingDevice = 0.25   (25% chance)

roll = random(0, 1)
caught = (roll < threshold)

The cloaking device is consumed whether or not you are caught. One device per scan event. The 30-minute cooldown is shared between patrol scans and port customs scans.
