Questions Fréquentes
What is a return on investment calculator?
A return on investment calculator helps you measure the efficiency of an investment by comparing the net profit to the original cost. Enter your initial investment, the final value, and the holding period — the calculator instantly returns your total ROI percentage and annualized CAGR so you can compare different investments on equal footing.
What is the ROI formula?
ROI = (Final Value − Initial Investment) ÷ Initial Investment × 100. For example, if you invest $10,000 and it grows to $15,000, your ROI is ($15,000 − $10,000) ÷ $10,000 × 100 = 50%. For annualized ROI, the formula is: (Final Value ÷ Initial Investment)^(1 ÷ Years) − 1.
What is the difference between ROI and CAGR?
ROI is the total percentage gain or loss over the full period. CAGR (Compound Annual Growth Rate) is the annualized equivalent — the steady yearly rate that would produce the same result. CAGR is better for comparing investments held different lengths of time.
What is a good ROI?
The S&P 500 has averaged about 10% annually before inflation (7% after). Real estate typically targets 8–12% including appreciation. For business investments, 15–30% is common. Context matters — compare against the risk and time horizon of similar alternatives.
Does this account for taxes or fees?
No — this calculates gross ROI. For a true after-tax return, use the after-tax net profit. For fund investments with management fees, use the net value after fees as your final value.
