How this calculator works
The split is computed in exact cents with the savings bucket taking the remainder, so the three parts always sum to your income precisely. Apply the percentages to actual take-home pay, not gross salary — that's the rule as designed.

Frequently asked questions
What is the 50/30/20 rule?
A budgeting framework popularized by Senator Elizabeth Warren: cap needs at 50% of after-tax income, wants at 30%, and direct 20% to savings and extra debt payments. Its power is simplicity — three buckets you can actually track instead of thirty categories you'll abandon.
What counts as a need vs a want?
Needs are what you must pay to live and work: housing, utilities, groceries, insurance, transport, minimum debt payments. Wants are everything you'd cut in a crisis: restaurants, subscriptions, travel, upgrades. The honest test: 'would I still pay this the month after a job loss?'
What if my needs exceed 50%?
Common in high-cost cities — the rule is a compass, not a law. Options: rebalance to 60/20/20, attack the biggest need (housing usually), or grow income. What matters most is protecting SOME fixed savings percentage; even 10% automated beats 20% aspirational.
Does the 20% include my 401(k)?
The classic rule works on after-tax income, so pre-tax 401(k) contributions are extra credit on top. If you prefer one number, add your 401(k) percentage mentally — someone deferring 8% pre-tax plus hitting the 20% here is saving at an excellent rate.
