ROI measures the profitability of an investment as a percentage of the original cost. A positive ROI means profit; negative ROI means loss. For time-based comparisons, use annualized ROI which accounts for the investment duration.
ROI = ((Final Value - Initial Cost) / Initial Cost) × 100%
Always include ALL costs (fees, taxes, maintenance) for accurate ROI calculation
Use annualized ROI when comparing investments with different time periods
A 'good' ROI varies by industry: 7-10% for stocks, 8-12% for real estate, 5x+ for marketing
Consider risk alongside ROI — higher returns often mean higher risk
Track ROI regularly to identify underperforming investments early
For marketing ROI, include customer lifetime value, not just immediate sales
Compare your ROI against industry benchmarks and alternative investments

The ROI formula is (Net Profit ÷ Cost of Investment) × 100.
If you invest $10,000 and receive $13,500 back, your net profit is $3,500 — the same dollar figure our profit calculator isolates from revenue and cost — and your ROI is 35%.
To calculate ROI from revenue and cost, subtract total cost from total revenue first, then divide by total cost.
This single percentage lets you compare the profitability of investments of any size on an equal footing.
Simple ROI ignores how long your money was invested, so a 35% return over five years looks identical to 35% in one year — but they are very different.
Annualized ROI converts the total return into an equivalent yearly rate using compounding, letting you compare a 2-year stock trade against a 7-year real estate hold.
Always annualize when the holding periods differ; otherwise long, slow investments look deceptively strong.
ROI measures total percentage gain and is best for quick comparisons and marketing (where ROAS, return on ad spend, is a close cousin).
For multi-year projects with cash flows at different times, IRR and NPV are more accurate because they account for the time value of money, which ROI ignores.
Use ROI for simple, single-period decisions and switch to NPV or IRR for capital budgeting and long-term investment analysis.
A "good" ROI depends entirely on risk and asset class.
The S&P 500 has averaged roughly 10% per year before inflation over the long run, so equity ROI is often benchmarked against that.
Real estate investors typically target 8–12% cash-on-cash returns, while marketing campaigns often aim for a 5:1 revenue-to-spend ratio (400% ROI).
Any ROI must be judged against the risk taken and the return of a safe alternative such as Treasury bonds.
The payback period tells you how long it takes to recover your initial investment — a $20,000 investment returning $5,000 per year has a 4-year payback.
It is a useful companion to ROI because it captures risk and liquidity: a high ROI with a 10-year payback may be riskier than a moderate ROI that breaks even in 18 months.
Pair payback period with ROI to balance total return against how quickly your capital is at risk.
The most frequent errors are:
Another trap is double-counting reinvested gains or omitting opportunity cost — the return you gave up elsewhere.
Accurate ROI requires a complete cost basis and a consistent time horizon.
ROI's biggest weakness is that it treats a dollar received today the same as a dollar received in ten years, even though money available now can be reinvested to earn more.
For any investment spanning multiple years, this distortion grows large.
When timing matters, use our NPV calculator and IRR calculator, which discount future cash flows to present value and give a more accurate picture of true profitability.
