Frequently Asked Questions
What should I do if my Needs exceed 50% of my income?↓
In high cost-of-living metropolitan areas, housing often forces Needs up to 60% or 65%. In this case, temporarily reduce the Wants category to 15% - 20% so you preserve at least 15% - 20% for emergency reserves and retirement.
Do minimum debt payments count as Needs or Savings?↓
Minimum required monthly payments on credit cards or loans count as Needs because failing to pay damages your credit profile. Extra debt payments beyond the minimum count toward the 20% Debt & Savings category.
Should I calculate my budget using gross or net income?↓
Always budget using net take-home pay (after federal, state, and payroll deductions), unless your 401(k) retirement contributions are deducted pre-tax, in which case add them back to both income and savings.
What is zero-based budgeting?↓
Zero-based budgeting assigns every single dollar a job (expenses, sinking funds, or investing) so that Total Income minus Total Allocated equals exactly zero at the end of the month.
