Idle Mafia Game Calculators

Choose the calculator that matches the resource decision in front of you. Property ROI models one 24-hour day using the visible 25% offline rate and optional +10% group-and-like bonus. Job Efficiency compares six checked New Ashport Tier 1 rows using displayed Energy, cash, XP, and item chance. Both tools keep assumptions visible, accept shareable URL inputs, and return an unavailable state instead of filling missing data with a guess.

Current inputs

Use the price, reward, and rate visible to your account whenever it differs from a preset.

Bounded comparison

A “highest” result refers only to the rows included in that calculator and the metric you selected.

Unknown systems

Mastery, hidden bonuses, theft, drop pity, and future balance changes stay outside the arithmetic.
