What it does
Projects circulating-currency growth and the resulting price index — the macroeconomic view your live MMO needs to avoid Diablo-3-launch-style hyperinflation.
How to use it
Enter starting supply, daily injection rate, sink rate, and project across days/months/years.
Designer tip
If money supply grows >2% per week with no sinks, market prices will 10× within a quarter. Add gold sinks (taxes, repair, cosmetics) early.
