One toolkit for every kind of investor

Most investment calculators assume you are buying one specific product. Investo works the other way around: you bring the asset — shares, index funds, rental property, crypto, gold, fixed deposits or your own business — and estimate the annual return you expect from it. The mathematics of compounding, instalments and inflation is identical regardless of what you invest in.

Every calculator updates instantly as you move a slider, draws a chart of your money over time, and breaks the result into what you put in versus what growth added. Switch between 20 currencies, flip to dark mode, or install Investo as an app and use it offline.

Which calculator do I need?

Private by design

Financial numbers are personal. Investo performs every calculation on your device — nothing you type is uploaded, logged or shared. There are no accounts, no cookies used for tracking, and the tools keep working with your internet switched off.

Frequently asked questions

Are Investo calculators free?
Yes — all four calculators are completely free, with no sign-up, no usage limits and no paywalled features.
Is my financial data private?

Which investments do these calculators work for?
Any asset that grows at a rate you can estimate: stocks, index funds, mutual funds, property, crypto, gold, fixed deposits or a business. Enter your expected annual return and the math is the same.
Which currencies are supported?
Twenty currencies including USD, EUR, GBP, INR, PKR, AED and JPY. Your choice is remembered on your device. The calculators format numbers only — they do not convert between currencies.
