How this calculator works
ROI (Return on Investment) measures the efficiency of an investment. A 50% ROI on a ₹10L investment generates ₹5L profit. But time matters — 50% over 1 year is very different from 50% over 5 years. This calculator shows both simple ROI and annualised ROI so you can compare investments on an equal basis.
ROI = (Net gain ÷ Total cost) × 100 | Annualised ROI = ROI × (12 ÷ Period in months) | Payback = Investment ÷ Monthly net gain

Include all costs
Most people underestimate total investment cost. Include setup, integration time, training, and ongoing maintenance.
Time matters for comparison
A 100% ROI in 6 months (200% annualised) beats a 120% ROI in 2 years (60% annualised). Annualise to compare.
Set a hurdle rate
Define your minimum acceptable ROI (hurdle rate) — typically 20–30% for business investments. Reject anything below.
