What is ROI Calculator?

Return on investment (ROI) % = (net profit ÷ investment cost) × 100, measuring gain relative to money spent.

Example: $2,500 profit on $10,000 ad spend?

ROI = (2,500 ÷ 10,000) × 100 = 25% — common for US marketing campaign post-mortems.

Does ROI include time value of money?

Simple ROI ignores timing; multi-year projects may need IRR or NPV for US/UK finance teams.

Negative ROI meaning?

Negative ROI means the investment lost money versus its cost.
