About this tool

The Budget Calculator simplifies personal finance by applying the popular 50/30/20 budgeting rule to your net income. It instantly categorizes your money into Needs, Wants, and Savings.

Why the 50/30/20 rule? Popularized by financial experts, this rule suggests dedicating 50% of your income to absolute necessities (rent, groceries), 30% to discretionary spending (dining out, hobbies), and 20% to savings or debt payoff. This tool allows you to customize those percentages to fit your unique financial goals.
