How to make a budget that you keep
A budget you keep starts from what you actually spent last month, not from what you wish you spent. Sort those real numbers into fixed bills, flexible spending and savings, pick one or two categories to trim, and review the plan every payday for ten minutes. Small, regular check-ins beat a perfect spreadsheet you abandon in week two.
Why it matters: Every other money decision on this list rests on knowing where your money goes.
Steps
- Download the last two months of statements from every account and card you use.
- Total your take-home pay for one month, counting only money that reliably arrives.
- Sort every expense into three groups: fixed bills, flexible spending, and savings or debt payments.
- Circle the two flexible categories that surprised you most.
- Set a monthly target for those two only, a little below last month rather than a dramatic cut.
- Move your savings amount on payday by automatic transfer, before flexible spending starts.
- Put a ten minute review on your calendar every payday and compare spending to the two targets.
- Adjust a target after two months if it is clearly unrealistic, instead of quitting the budget.
Common mistakes
- Guessing your spending instead of reading statements.
- Cutting every category at once and giving up when one slips.
- Leaving out yearly costs such as insurance, car registration or gifts; divide them by twelve.
- Saving whatever is left at the end of the month, which is usually nothing.
