Fund face-off: compare two funds on what actually matters, in plain English
You're choosing between two funds and the fact sheets are opaque. Compare them on cost, holdings, and fit — educational, not investment advice.
The prompt — copy and run it
You are an investing educator (not my advisor) comparing two funds so I can understand the difference. I will paste the details. Produce: A) SIDE-BY-SIDE — a table: what each fund actually holds in plain terms, expense ratio, rough diversification, and how much they overlap. B) COST OVER TIME — the 20-year compounding cost difference of the two expense ratios at a balance I give you. Show the math. C) FIT QUESTIONS — the questions the choice really turns on (my timeline, what I already own, tax location), which the fund sheets can't answer. D) ADVISOR PROMPTS — the 3 questions this comparison suggests I bring to a licensed professional. Inputs: [FUND A DETAILS] · [FUND B DETAILS] · [ROUGH BALANCE I'D INVEST] · [MY TIMELINE + WHAT I ALREADY HOLD] Rules: Do not invent expense ratios, returns, or holdings — use only what I paste and mark anything to 'verify on the fund page'. Do not tell me which to buy — this is an educational comparison and the decision is mine and a licensed professional's. Never include account numbers.
How to use this prompt

Why this prompt works
Fund choices get made on brand or recent returns while the fee — the one input that reliably compounds against you — stays invisible; a side-by-side that surfaces overlap and shows the 20-year cost math makes the real difference legible — and the strict no-buy-signal, verify-the-numbers framing keeps it education the reader acts on, not advice from an unlicensed model.

When should I use this prompt?
You're choosing between two funds and the fact sheets are opaque. Compare them on cost, holdings, and fit — educational, not investment advice.
Why does this prompt work?
Fund choices get made on brand or recent returns while the fee — the one input that reliably compounds against you — stays invisible; a side-by-side that surfaces overlap and shows the 20-year cost math makes the real difference legible — and the strict no-buy-signal, verify-the-numbers framing keeps it education the reader acts on, not advice from an unlicensed model.
What mistake does this prompt help you avoid?
Ignoring fees / hidden overlap — a side-by-side with 20-year cost math makes the real difference legible as education, never as a buy recommendation.
