1Start with costs you have
Read recent statements and bills. Remove categories you do not use and add missing commitments, such as childcare or insurance.
2Keep different decisions separate
Groceries and takeout can share a food group while keeping separate limits. A merchant name alone may not explain what you bought.
3Give mixed purchases one clear treatment
Split a shop across categories when that detail matters. Keep the parts equal to the actual purchase so the total stays the same.
4Keep transfers out of spending totals
Moving money to savings is a transfer toward a goal. Paying a card bill should not repeat purchases already logged as expenses. Review your recording method consistently.

Build your monthly planFrequently asked questions
How many categories should I have?
Use enough to make useful choices. If a category never changes a decision, combine it with a broader group.
Should savings be a category?
Include savings in the plan, but distinguish a planned allocation from an actual deposit. Do not count the same money twice.
