Your Income

The 50/30/20 rule is a simple budgeting guideline: 50% of take-home pay toward needs (rent, groceries, utilities), 30% toward wants (dining out, entertainment, subscriptions), and 20% toward savings and debt payoff beyond minimums.

Frequently Asked Questions

Is my income private?

Yes. The figure you enter never leaves your browser tab — there's no server-side calculation, no account, and no tracking of what you type here.

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

Needs are things you must pay to live and work — rent or mortgage, groceries, utilities, minimum debt payments, transportation. Wants are everything discretionary — dining out, streaming subscriptions, hobbies, travel. The line isn't always obvious, and that's normal; the 50/30/20 split is a starting guideline, not a strict rule.

What if my numbers don't fit 50/30/20?

Very common, especially in high cost-of-living areas where needs can easily exceed 50%. Treat this as a reference point to work toward, not a requirement.

Is this financial advice?

No, this is a simple split based on a popular budgeting guideline, not personalized advice.
