Do I enter euros or percentages?

Either. The weights are normalised before anything is aggregated, so entering 7000 and 3000 produces exactly the same breakdown as entering 70 and 30. Use whichever you have to hand — actual balances are usually less error-prone than percentages you have worked out yourself.

Why is there an Other slice?

Published breakdowns list the largest categories and stop, so the listed slices rarely sum to 100%. The remainder is shown as Other rather than dropped, because dropping it would silently inflate every named slice — a fund whose disclosed sectors cover 85% of assets would otherwise appear to have 100% of its money in them.

Does this show my actual holdings?

No. It shows exposure, not positions. It cannot tell you that you own a particular company, only that a given share of your money sits in a country or a sector. For the company-level question, the overlap checker compares two funds against their disclosed holdings directly.

Portfolio X-ray: what you actually own across your funds

A portfolio of several funds feels diversified because it is several funds. Whether it actually is depends on what sits inside them, and fund names are designed to describe a strategy rather than an exposure. Two holdings that look unrelated on a statement can resolve into the same country and the same handful of sectors once you look through to what they hold.

The calculator

How it works

Enter each fund and a weight. The weights are normalised, so euros and percentages both work and you can type whatever you already have in front of you — only the proportions matter. For each fund the published country and sector breakdowns are taken, an explicit Other slice is added so each fund's allocation sums to a full 100% rather than quietly under-counting, and the results are weighted and summed into one combined view sorted by size.

What it assumes

The breakdowns are the published point-in-time figures for each fund, not live positions, and they move as the fund and its index move. Only funds with allocation data on record can be selected. The look-through stops at the fund's own published breakdown: a holding that is itself a diversified instrument is not decomposed any further, so this measures declared exposure rather than ultimate exposure.
