About VOO Calculator
What we do
VOO Calculator is a free, independent tool built to help people explore how a VOO investment could grow over time under different assumptions. It's a calculator first — the goal is a clear, honest projection tool, not a place to sell a particular investment view.

Muhammad Hamza is the independent creator and maintainer of VOO Calculator.

How data is sourced: fund figures like expense ratios, dividend yield, and holdings are checked against Vanguard's own VOO fund page before publishing. Historical return and price data (e.g. the year-by-year returns table) is computed from Yahoo Finance's adjusted monthly closes, which may differ slightly from Vanguard's own published figures. Every calculator's formulas are documented in full on the methodology page rather than left as a black box.
