Budget Calculator
A monthly budget worksheet that sorts spending into needs, wants and money put away. Enter your take-home pay and what you spend under each heading, and it returns the three group totals, each as a share of income, the surplus or shortfall, your savings rate, and how far the month sits from the 50/30/20 shares. A second action just splits a pay figure into those three shares, with the percentages editable if 50/30/20 does not fit your rent. Where a line belongs is a judgement rather than a fact, so the three totals are worth reading as the shape of a month rather than as a score.
