Game Economy Balance Calculator

Every game economy with a soft currency runs on faucets (ways players earn currency) and sinks (ways currency leaves circulation), and the balance between the two determines whether that currency holds its value over time or gets inflated into meaninglessness. This calculator's central figure is net daily currency per player — faucet minus sink — which, if positive, means the average player accumulates currency faster than the game removes it, exactly the dynamic that eventually devalues in-game prices and makes early rewards feel worthless later. Daily inflation rate expresses that same net accumulation as a percentage of the sink, giving a normalized sense of how fast the imbalance compounds regardless of the currency's absolute scale.

Sink ratio flags the specific range most game economists consider healthy: sinks removing 70-90% of what faucets generate lets players feel real progress and accumulation while still preventing runaway currency growth, and this calculator marks anything in that band as healthy and anything outside it as unbalanced. Days to double balance and total currency after 30 days translate the daily imbalance into concrete milestones — a game showing players doubling their currency in a handful of days is signaling an economy that will need active management, new sinks, or price adjustments well before that inflation becomes visible in player complaints about prices feeling pointless. This model uses flat daily averages across all players and doesn't distinguish between casual and high-engagement players, whose actual faucet and sink behavior in a live economy typically varies substantially from any single average figure.
