Senator Elizabeth Warren popularized the 50/30/20 rule in her book All Your Worth. It splits after-tax income into three simple buckets.
The three buckets
Needs get 50%: housing, utilities, groceries, insurance, minimum debt payments and transportation. Wants get 30%: dining out, entertainment, subscriptions and travel. Savings and extra debt payments get 20%. On $5,500 of take-home pay that is $2,750, $1,650 and $1,100.
Strengths and limits
The rule is easy to remember and flexible. But in expensive cities, housing alone can exceed 50% of pay. If so, try 60/20/20 or 60/10/30, trim wants first and aim to grow the savings share over time.
Making it work
Use your bank's categories or an app for a month to see where you are. Classify honestly. Automate the 20% on payday and treat anything left as spendable. Revisit when income changes.
Try the numbers
Use our 50/30/20 Budget Calculator to see this in practice. With its default example (Monthly take-home pay: $5,500; Actual needs spending: $3,200; Actual wants spending: $1,500), it shows recommended savings (20%): $1,100. Adjust the inputs to match your situation.
Key takeaways
- 50% needs, 30% wants, 20% savings and debt payoff.
- Adjust the percentages to fit your cost of living.
- Automate the savings portion first.
