Flexible spending

This is where the month usually gets messy.

Savings and goals

Saving is not leftover money. It gets a job too.

What does zero-based budgeting mean?

A zero-based budget means your income minus spending, bills, savings, and goals equals zero. It does not mean you spend every dollar. It means every dollar has a job before the month starts.

If this calculator says you still have money left, that is not a failure. It just means you still need to decide where that money should go. If it says you are over budget, the plan needs a small reality check before the month begins.
