ROI Calculator

Calculate return on investment, payback period, and risk-adjusted scenarios for any business investment. Pure math — no guesses.

How it works

Calculates return on investment using the standard finance formula: ROI = (Net Profit ÷ Investment Cost) × 100. Also calculates annualized ROI for fair comparison across different time horizons, payback period in months, and three risk-adjusted scenarios (conservative, base, optimistic) based on your selected risk level. No spreadsheet needed.
