📐 How ROI Is Calculated
The calculator uses these formulas to determine upgrade value:
- Income After = Current Income × (1 + Boost% / 100)
- Income Gain/sec = Income After − Current Income
- Break-Even Time = Upgrade Cost ÷ Income Gain per second ÷ 3600 (hours)
- Net Profit = (Income After − Current Income) × Period in Seconds − Upgrade Cost
- ROI % = Net Profit ÷ Upgrade Cost × 100
A Buy Now recommendation is given when the break-even time is less than 25% of the time period, and the net profit is positive. Otherwise, Wait is shown.
