Frequently Asked Questions
Why does annualized ROI differ from total ROI?
Total ROI is the overall gain over the whole period; annualized ROI spreads that gain evenly per year using compound growth, so it's comparable across investments of different lengths.
Can ROI be negative?
Yes, if the final value is less than the original investment.
What inputs does the ROI Calculator need?
You'll need to provide: Investment, Final value, Years. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the ROI Calculator?
The ROI Calculator applies the formula exactly as calculated — ROI % = ((final value − investment)/investment) × 100. Annualized ROI % = ((final/investment)^(1/years) − 1) × 100. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Are these results guaranteed?
