Have you heard of the 65/20/15 budget framework?
The 65/20/15 framework is a commonly used adaptation of the 50/30/20 rule. It adjusts for higher essential costs while still reserving income for saving and investing.
For many people, a limitation of the 50/30/20 model is that modern living expenses often exceed 50% of income.
50/30/20 Framework
50% — Essentials
Rent, bills, groceries
30% — Fun
Discretionary spending
20% — Savings & Investments

15% — Savings & Investments

Takeaway
Both frameworks allocate income across the same three categories and explicitly reserve a percentage for savings and investments.
The difference is how much income is allocated to essentials in response to real-world living costs.
Choose the framework that reflects your actual expenses while still protecting saving and investing.
