401K-O

What is 401K-O?

I can max out my 401(k) every year, but every time I get a raise/bonus I have to re-figure out what percentage to set my contributions to. After googling several times with no luck and doing the math myself, I got fed up — this is the entire reason computers exist. So I built 401k-o.com. Free, no email, no login. Includes a "show me the math" breakdown and a whole-percent rounding toggle for plans that require it. US only for now — working on expanding that!
