Return on investment (ROI) is the simplest way to judge whether something was worth the money: ROI = (amount returned - amount invested) / amount invested x 100. It works for anything with a cost and a payoff, a marketing campaign, a new tool, a piece of equipment, a property or a stock position, which is exactly why it is the first number people ask for.
This free ROI calculator gives you the net gain and the ROI percentage instantly, and if you add how long the investment ran, it also shows the annualized ROI, so a 30% return over three years can be compared fairly against a 12% return in one. Plain ROI ignores time; annualized ROI is what makes different investments comparable. Everything runs in your browser with no signup, and nothing you enter is stored.
