How this calculator works
Enter monthly take-home income, current essentials, wants or fun spending, and savings, investing or debt repayment. The calculator compares those buckets with the selected rule and shows target amounts, current percentages and over/under amounts by category.
50/30/20 vs 65/20/15
The 50/30/20 rule splits take-home income into 50% needs, 30% wants and 20% savings or debt repayment. The 65/20/15 rule uses 65% essentials, 20% fun or discretionary spending and 15% saving or investing. Some people describe the second rule as 15/65/20 when the savings bucket is listed first.
Neither split is treated as automatically better. A larger essentials bucket can make a rule feel more realistic when housing, bills or transport take a larger share of income, while 50/30/20 leaves a larger default savings and debt-repayment bucket.

The result will show essentials above the selected rule target. That can be a prompt to compare assumptions, not a judgement on the entered budget.
Does this calculator give financial advice?
No. It provides a rule-of-thumb comparison based on the numbers entered, not financial, tax, legal, accounting, investment or debt advice.
