SteadyGrow is a hub for S&P 500 DCA, dollar-cost averaging, and what-if questions — on published prices, not a made-up return rate.
Search a habit → run it on history → leave with a number.
Same contribution schedule across assets and stories — crash windows, boring alternatives, and long-tail what-ifs.
DCA guides for SEO questions — plus detailed notes on what we tested (timing, sectors, dual momentum) and why we do not sell a paid allocator.
Don't predict the future.
Understand the past.
