Frequently asked questions

What is the 50/30/20 rule?

A simple budgeting guideline: spend 50% of after-tax income on needs, 30% on wants, and put 20% toward savings and extra debt payments.

What counts as a "need" versus a "want"?

Needs are essentials you can't easily cut — rent, utilities, groceries, minimum debt payments. Wants are discretionary — dining out, entertainment, subscriptions, hobbies.

Can I change the percentages?

Yes — drag the sliders to any split that fits your situation. The 50/30/20 split is a popular starting point, not a strict rule.
