How ROI works
Return on investment measures how much an asset or campaign earned relative to what you put in. The headline ROI is (final value − invested) ÷ invested, but a multi-year hold calls for CAGR to smooth out yearly ups and downs, and money-weighted math when you keep adding cash.
Flip on inflation and the answer drops into real terms — the return that beats prices rising. Each scenario template preloads typical numbers for stocks, rental property, e-commerce or a marketing campaign.
