Set a default paycheck split that diverts a modest percentage to an emergency fund until it hits a target, then flows into a higher-yield account. Jamal set 4% by default and barely felt the difference, but after six months had a meaningful cushion. The system paused contributions during a short gig gap and resumed automatically. Clear previews of upcoming pay stubs made the commitment feel safe, predictable, and reversible.
Roundups work best when they notice your financial rhythm. Defaults can increase the roundup amount during flush weeks and throttle during tight ones, targeting a monthly savings goal. Caps prevent runaway transfers, and a rainy-day meter shows how close you are to your safety target. People stick with it because the behavior feels responsive, not rigid. The surprise comes later, when the tiny drips collect into a serene pool of resilience.
