🎯 Understanding ROI
ROI (Return on Investment) tells you how quickly an upgrade pays for itself. Lower payback time = better investment.
- • Excellent: Payback under 10 minutes
- • Good: Payback 10-60 minutes
- • Fair: Payback 1-4 hours
- • Poor: Payback over 4 hours
💡 Pro Tips
- • Compare multiple sources before investing
- • Factor in all your active bonuses for accurate results
- • Prioritize upgrades with payback under 1 hour
- • Managers double your effective income (always worth it)
- • Use this before making expensive late-game purchases
