50/30/20 Budget Calculator

The 50/30/20 rule is one of the most widely cited budgeting frameworks because it is simple enough to remember and flexible enough to adapt. The idea is to allocate 50% of after-tax income to needs, 30% to wants, and 20% to savings and debt repayment. This calculator applies that framework to your income and compares it against your actual spending so you can see where the gaps are.

The value is not in the exact percentages — those are guidelines, not laws. It is in having a structure for evaluating tradeoffs. If your needs consume 65% of income, the calculator shows that clearly, and you can decide whether to increase income, reduce housing costs, or adjust the wants category. The visual comparison between ideal and actual allocation makes the conversation concrete instead of abstract. Most people who feel financially stretched have never mapped their spending to a framework, which is exactly what this tool does.
