Why ROI Matters for Investment Decisions
Return on Investment (ROI) is a critical metric for evaluating the profitability of investments and business decisions. It allows you to compare different investments on equal footing by expressing returns as a percentage of initial capital.
By understanding ROI, you can make data-driven decisions about where to allocate your capital. Investors, business owners, and financial advisors use ROI to evaluate stocks, real estate, business ventures, and marketing campaigns.
