How it's calculated
ROI is the gain divided by what you put in, as a percentage: get $13,000 back on $10,000 and the gain is $3,000, which is 30%. Dividing by the years held gives a simple average per year, so you can compare investments held for different lengths of time. It is an average, not a compound rate; a 30% return over two years is 15% a year on this measure and about 14% compounded.
What counts as the amount invested?
The full cost: purchase price plus fees, commissions, closing costs, repairs or setup. Leaving costs out flatters the result. For the amount returned, use what you actually received after selling costs, or the current value if you still hold it.
What is a good ROI?
It depends on the risk and the time. The US stock market has averaged about 10% a year over long periods; a savings account 1–5%; a rental property 5–10% on cash invested; a business or marketing campaign is often judged against 20% or more because the risk is higher.
Why is the per-year figure not a compound rate?
Gravity Forms core cannot take roots, so the tool divides the total return by the years. For short periods or modest returns the two are close; over many years the compound rate (CAGR) is lower than the simple average. The Compound interest calculator on this site works the other way, from a rate to a value.
