FAQ

What’s the difference between ROI and annualized ROI?

ROI shows your total return over the entire holding period. Annualized ROI averages that return per year, making it possible to fairly compare a 2-year investment with a 5-year investment.

Can ROI be negative?

Yes. If your final value is less than your initial investment, the ROI will be negative, indicating a loss. This is still useful — it tells you an investment isn’t working and lets you compare losses across options.

Should I include fees in my investment amount?

Yes. For accurate ROI, include all costs — purchase commissions, transaction fees, taxes, maintenance costs, and any other expenses related to the investment.

Is a 10% ROI good?

It depends on the investment type, risk level, and time period. A 10% annualized ROI is generally solid for stocks but may be low for high-risk ventures. A 10% total ROI over 5 years (roughly 2% annualized) is below average.

Tips

• Always use the time period field to get annualized ROI — it gives you a realistic apples-to-apples comparison
• Include all expenses in your initial investment amount for the most accurate picture
• Use this calculator before making major purchases to evaluate whether the expected return justifies the cost
• Compare ROI across different investment types to diversify your portfolio effectively
