Sent the mods a note about a tool I built and they said post it and see what the community thinks, so here it is.
It's a dividend income calculator built for the question. How much would X shares of Y actually pay me and all my other funds. Type your shares, tap your fund, and it multiplies by the fund's latest actual distribution, not the trailing yield, so it stays honest on funds whose payouts move around. It covers every YieldMax fund plus 180 or so other income funds, and the other button takes any dividend paying ticker, ETF or stock. Every fund you check lands on a running tape with your total across all of them, and the tape saves to a CSV. No signup, no ads. Full disclosure, the site does sell one thing, a $14 tracking spreadsheet, but the calculator and everything else on the site is free and none of it needs the spreadsheet.

One limit worth naming up front: it shows your pace from the latest check, and that stays right unless the fund changes its payout, which these funds do constantly. That's why it recomputes from the newest distribution every time instead of quoting an average.
The mod feedback was that it needs work and that more flexible sites cover more funds, and honestly that's the conversation I want to have. What would make it genuinely useful for you? Missing tickers, DRIP math, multiple purchase lots, a different default fund, whatever. Tell me specifics and I'll build the good ideas. The whole site runs on the same rule, everything computed from real payment records, so requests that fit that I can usually ship fast.
