How it works
Methodology & formulas
This calculator is transparent by design. Review the steps and formulas so you can trust the estimate and adjust assumptions when your dashboard differs.
Calculation steps
- 1Total cost = investmentAmount + recurringCost × periodMonths.
- 2Net gain = returnAmount − total cost.
- 3ROI percent = net gain ÷ investmentAmount × 100.
- 4Annualized ROI = ROI percent × 12 ÷ periodMonths when period is provided.
- 5Payback months approximates when cumulative profit equals investment.
- 6Profit ratio = returnAmount ÷ investmentAmount.
Formulas
- Total cost = investment + (recurring × months)
- Net gain = return − total cost
- ROI % = netGain ÷ investment × 100
- Annualized ROI = ROI % × 12 ÷ months
- Return multiple = return ÷ investment
Important assumptions
- Net gain subtracts recurring monthly cost times period months from simple return minus investment.
- Annualized ROI multiplies ROI by 12 divided by period months.
- Payback estimate assumes profit accrues evenly over the period.
- ROI does not include time value of money, taxes, or financing costs unless you add them.
- Return multiple is total return divided by investment.
