Frequently asked questions

Are these calculators free?

Yes, free with no login and no ads. They run in your browser; nothing you type is sent anywhere.

How accurate are they?

They use standard formulas (monthly-compounded SIP, compound growth, XIRR by bisection). Results depend on the return and inflation you assume.

Can I use the numbers for my own portfolio?

Yes: Capital Friends, the free app behind these pages, applies the same maths to your real mutual funds, stocks, EPF and FDs for the whole family.

Calculators use the inputs you enter and standard formulas; results are estimates, not guarantees. Returns from mutual funds, stocks and other investments are not fixed and can be lower than assumed. Capital Friends is a tracking tool and is not a SEBI-registered investment adviser; nothing here is a recommendation to buy or sell any security.
