Corrections, questions, and feedback are all welcome. Messages are usually answered within a few business days.
Replace this with a real address before publishing. A free forwarding address on your own domain looks more credible than a personal Gmail account, and most registrars include email forwarding at no extra cost.
Wrong math, a fund figure that looks off, or a number that does not match your own broker. Include the inputs you used so it can be reproduced.
A fund you want added, a calculation the tool does not handle yet, or something that was confusing to use.
A chart that did not render or a control that stopped responding. Mentioning your browser and device helps a lot.
Partnership, licensing, or press inquiries.
Personal investment advice is outside what this site does. Questions like which fund to buy, how to allocate a specific portfolio, when to retire, or what to do with a particular account cannot be answered here. This is a general educational tool, not an advisory service, and answering those questions would require knowing your full financial picture. A licensed financial professional is the right place for that.
This site is run by one person, so replies are not instant. Corrections to data or math are prioritized over everything else.
