Everything on ReturnKoto?
Start from what you want to know. Every tool here runs on the same verified NAV history and AMC portfolio statements.
Check what an amount became
Enter an amount and period, see what a monthly SIP or lump sum would have become in every tracked fund, with dividends reinvested by default or taken as cash.
Find and compare funds
All 35 tracked funds with returns, NAV charts, verified fees and holdings.
Pick two or three funds: returns, rolling windows, path risk, fees, holdings, and for two funds a diversification snapshot (same stocks, same sectors, co-movement).
See what funds own
Which stocks appear most across the funds, high-overlap pairs, low-overlap diversifiers, and a build-your-own overlap checker for any two or three funds.
Which pairs of funds hold the most of the same stocks. Two funds that overlap heavily give you less diversification than their names suggest, so this is worth checking before holding both.
The opposite view: pairs whose disclosed holdings have the least in common, so each one is doing something the other is not.
Pick any two tracked funds and see their shared and separate holdings side by side, from the asset managers’ own portfolio statements.

How ReturnKoto? works
The canonical description of how every number is collected, validated and computed, including the rules a NAV must pass and how to cite the data.
AMC-Verified, estimated, partial, + dividends, SHARIAH and fund types, explained in detail with how each one is decided.
Independence, funding, inclusion rules, AMC-Verified, and how to reach ReturnKoto? at hello@returnkoto.com. No AMC pays for badges, rankings or placement.
Calculator amounts stay in your browser. What analytics collect, what stays on your device, and which links leave the site.
Personal use and citation are welcome. Commercial cloning of the product is not. Source code is PolyForm Strict.
Still being calibrated, and the data is still being verified. Every sub-score and the star arithmetic are published so you can check them, but treat the stars as a draft, not a recommendation.
