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?
- Compound interest — you have a lump sum (and maybe monthly top-ups) and want to know what it becomes in N years.
- SIP & returns — you invest a fixed amount every month and want the projected maturity value.
- Loan EMI — you are borrowing for a house, car or anything else and want the true monthly cost and total interest.
- Retirement — you want to know what your savings rate today means for the income you can draw later.
Private by design
