What did it really make? Get ROI, net profit and CAGR — then add extra contributions and inflation for the number that actually counts.
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.

Cash-on-cash, cap rate, cash flow, appreciation and payback — which one actually tells you if a deal works.

A real small-business example — how to size a purchase against the monthly savings it should return.
How long your money takes to double, why the Rule of 72 shaves years off the truth, and where fees hide.
