Frequently asked questions

How do I calculate ROI?

ROI = (amount returned - amount invested) / amount invested x 100. If you invest 100,000 and get back 150,000, the net profit is 50,000 and ROI is 50%. The tool shows net profit, total ROI and annualised ROI from the amounts and period you enter.

What is annualised ROI (CAGR)?

Annualised ROI is the steady yearly growth rate that would turn your investment into the final amount: (returned / invested) ^ (1 / years) - 1. For 100,000 growing to 150,000 in 3 years, it is 1.5^(1/3) - 1, about 14.47% per year, not 50% / 3.

Why is annualised ROI not simply total ROI divided by years?

Because returns compound. A 50% total gain over 3 years averages 16.7% if you just divide, but the compounding rate is about 14.47%. The compound figure is the fairer way to compare investments held for different lengths of time.

What is a good ROI?

There is no single answer; it depends on the risk, the time period and your alternatives. A 10% ROI over one year and over five years mean very different things. Compare annualised ROI with what a safe option pays, and remember past results do not guarantee future returns.

Can I enter the investment period in months?

Yes. Choose months or years as the period type. Months are divided by 12 before annualising, so 18 months is 1.5 years. Using a period of zero gives no annualised figure, so enter a positive duration.

Does ROI include fees, taxes and inflation?

Only if you include them. The tool uses the amounts you type, so subtract brokerage, fees and taxes from the returned amount to get a net figure. Inflation is not adjusted, so the real purchasing power gain is lower than the ROI shown. This is not financial or tax advice.

Is my data shared when using the ROI Calculator?

No. Toolskyt operates under a zero-server policy. All calculations, data formatting, and file exports are executed locally on your machine.
