DuckDollar

Every time I wanted to check a quick number, rent vs buy, my FIRE target, a rough tax estimate, the tool that could tell me was either behind a signup wall or buried in ads. The math isn't complicated. There's no reason it should cost an email address or twelve bucks a month.

So I built DuckDollar. Free personal finance calculators, no account, no upsell. You do the thing you came to do and leave.

It runs on Astro, so it's fast and cheap enough to keep free for good. I'm not chasing a launch spike. The plan is organic search, adding tools people actually look for and letting them compound.
