よくある質問
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?
No. The ROI Calculator gives an estimate based on the numbers you enter and standard financial formulas — actual rates, fees, taxes, and terms vary by lender, institution, and jurisdiction, and can change over time. This is not financial advice; consult a qualified financial professional for decisions specific to your situation.
Is the ROI Calculator free to use?
Yes, the ROI Calculator is completely free, requires no signup, and runs instantly in your browser.
