💹 Your Return, Measured
What is an ROI Calculator?
An ROI calculator answers the most basic question in finance: did this investment pay off, and by how much? From the money you put in and the value you ended with, it derives the net profit and the return as a percentage — and, when you tell it how long you held the position, the annualized rate that lets you compare it fairly against investments of different durations.
Use it to evaluate a stock, a property, a marketing campaign, or a piece of equipment, and to compare options on equal footing. The results are general informational estimates, not professional tax, accounting, or financial advice — consult a CPA or financial advisor before investing.
❓ Frequently Asked Questions
How is ROI calculated?
Return on investment is net profit divided by the amount invested, expressed as a percent: ROI = (final value − initial investment) ÷ initial investment × 100. If you put in $1,000 and ended with $1,500, the net profit is $500 and the ROI is 50%. A negative result means you lost money on the investment.
What is annualized ROI (CAGR), and why does it matter?
Simple ROI ignores time, so a 50% total return looks the same whether it took one year or ten. Annualized ROI — the compound annual growth rate (CAGR) — restates the gain as a steady yearly rate using (final ÷ initial)^(1 ÷ years) − 1. It's the fair way to compare investments held for different lengths of time. This tool shows it whenever you enter a holding period in years.
What counts as a good ROI?
It depends entirely on the asset, the risk, and the time frame, so there's no universal benchmark. Compare an investment's return against a relevant alternative — a market index, a savings rate, or the next-best project — rather than an absolute number, and always weigh the return against the risk you took to earn it.
Does ROI account for fees, taxes, and inflation?
Not on its own. Plain ROI uses the cash in and the cash out, so for a true picture you should net out transaction fees, taxes, and the effect of inflation. These are general informational estimates, not professional tax, accounting, or financial advice — consult a CPA or financial advisor before investing.
