What is ROI Calculator?
The ROI Calculator tells you how much return you got (or will get) on an investment relative to its cost. Enter your initial investment amount and the final value, and you'll instantly see the ROI percentage, net profit or loss, and a multiplier showing how many times your money grew.
ROI is used everywhere — evaluating marketing campaigns, comparing business investments, assessing stock returns, reviewing real estate deals, or deciding whether a project was worth the cost.

Frequently asked questions
ROI = ((Final Value − Initial Investment) / Initial Investment) × 100. A positive result means profit, negative means loss.
It depends on the context. Stock markets historically return ~7-10% annually. A marketing campaign ROI above 100% (doubling spend) is generally considered strong.
A multiplier of 2x means your money doubled. 0.5x means you got back half your investment.
