About FundOverlapCheck

A small tool that does one useful job clearly.

Editorial review required before launchBuild edition: September 2026Sources and limits below

Free tool to compare two ETFs, see shared holdings, and model how your allocation changes the combined portfolio. Import your own dated holdings.

Built around the question

The core tool is free to use. There is no login wall, mandatory email capture, or paid unlock hiding the calculation. Inputs, exports, and methods belong together so you can inspect the result rather than take a black-box score on faith.
