Where your income goes each month
| Bucket | Share | Weekly | Monthly | Annual |
|---|---|---|---|---|
| Needs | 50% | $461.54 | $2,000.00 | $24,000 |
| Wants | 30% | $276.92 | $1,200.00 | $14,400 |
| Savings | 20% | $184.62 | $800.00 | $9,600 |
The 50/30/20 rule
Popularized by Elizabeth Warren and Amelia Warren Tyagi (All Your Worth, 2005), the rule splits take-home pay three ways: 50% for needs, 30% for wants and 20% for saving and paying down debt. It is a starting framework rather than a law, and it works because it is simple.
Methodology: each bucket is income × its percentage; weekly figures are annual ÷ 52. The savings bucket covers saving and investing as well as extra debt paydown above minimums.
Adapting it
In high-cost cities needs may take 60% or more. If so, trim wants first rather than saving less. Early in your career or when clearing expensive debt you might flip to 50/20/30 or even 50/10/40. Whatever you choose, the calculator checks that your buckets add up to 100%.

Frequently asked questions
Should I use pre-tax or after-tax income?
After-tax income, the money that actually lands in your bank account. If your retirement contributions are pre-tax, add them to your income first, then count them as savings.
Do minimum debt payments count as needs?
Yes. Minimum payments are a need, while extra payments above the minimum belong in the savings and debt paydown bucket.
What if I cannot reach 20% savings?
Start with what you can, even 5%, and increase it with every raise. Consistency matters more than the starting percentage.
