How it works: the 50/30/20 rule is a simple guideline that puts 50% of your after-tax income toward needs, 30% toward wants and 20% toward savings and debt payoff. If your living costs are high, try the 60/20/20 or 70/20/10 split, or choose a custom split of your own. If you also enter what you really spend now, the calculator shows where you are over or under the plan, and whether any income is left without a job.

Good to know: this is an educational tool and not financial advice. The percentages are starting points, not rules, so adjust them to your own situation. Nothing you type is stored or sent anywhere.
