The 50/30/20 budget, worked through

The 50/30/20 rule splits your take-home pay into three buckets: needs, wants and savings. It became popular through Elizabeth Warren and Amelia Warren Tyagi's book All Your Worth. Treat it as a starting split you adjust, not a test you pass or fail.

A worked example

Assumptions for illustration only:

What counts as a need

Rent or mortgage, utilities, groceries, transport to work, insurance and the minimum payment on every debt. Eating out, streaming, new clothes beyond the basics and phone upgrades are wants, even when they feel essential.

When needs take more than half

In expensive cities rent alone can pass 40% of take-home pay. That is normal, and the fix is to shrink wants first, not savings. A 60/25/15 split on the same pay still saves $480 a month, or $5,760 a year.

Make it automatic

Schedule a transfer to savings on payday, before you can spend it. Then track only one number each month: did the savings transfer happen? If it did, the rest of the budget is doing its job.
