Watching money come in and go out across a whole month shows timing problems that monthly totals hide.
What to do each day
Log money in and out on the day it happens.
What to notice
- The weeks when money runs lowest.
- When your large payments land compared with your income.
- Costs that come around only occasionally.
At the end, ask yourself
- Where in the month is money tightest?
- Would moving a payment date or saving earlier help?
Lessons behind this

- Fixed, variable and irregular expenses — Three kinds of cost behave differently, and the irregular ones are what usually break a budget. (6 min · Foundation)
- Sinking funds and the emergency line — Saving a little each month for costs you know are coming, plus a line for the ones you don’t. (6 min · Practical)
