Illustrate a planned 50/30/20 allocation of monthly take-home income in USD, with exact cent totals; actual expenses are not entered.

Illustrative 50/30/20 allocation of monthly take-home income. Actual expenses and cash flow are not entered; this does not determine whether you are under budget. Adjust the targets to your circumstances.

Income is rounded to the nearest cent, with half cents rounded up. Category cents are assigned by the largest fractional remainder; ties go to needs, wants, then savings. The categories add up to the rounded income.

What this planned allocation includes

The single income input is monthly take-home income in USD. The calculator allocates 50% to needs, 30% to wants and 20% to savings or debt payoff. This is an illustrative plan, not a recommended allocation for every household. Actual bills, spending and cash flow are not entered, so the result does not establish whether you are under budget.

Income rounds to the nearest cent, with half cents rounded up. Remaining category cents follow the largest fractional remainder; ties go to needs, wants, then savings. Categories sum to rounded income. Zero income is explicit; positive income below $0.005 cannot form this cent-based plan. Savings or debt payoff is a reserve, separate from planned spending. The localized PDF worksheet preserves the entered income and these assumptions.
