Monthly and weekly cash flow

Timing matters as much as totals: a month can balance on paper and still run dry in week two.

The idea

A budget can balance for the month and still run short in the middle of it. Monthly cash flow looks at the total coming in and going out over a month. Weekly cash flow looks at when: if rent leaves on the first and pay arrives on the twenty-eighth, the whole month is lived on last month’s money.

Mapping money week by week shows the low points — the days when a surprise would push you into overdraft or borrowing. Small changes in timing help: moving a bill date to just after payday, spreading large payments, or keeping a small buffer in the everyday account for the lowest week.

Why it matters

Cash-flow problems are often timing problems, and timing problems are often easy to fix once they are visible.

A real example

The situation

Every month Dayo runs out in the third week, even though his monthly budget balances.

What happened

He maps his payments by week and finds three large bills cluster just before payday. He asks two providers to move their dates, and the third-week squeeze disappears.

The takeaway

The problem was when money left, not how much.

How people actually behave

People think about money in monthly totals because pay and bills are monthly, and so they miss the weekly shape of their cash flow.

Common mistakes

• Checking only the monthly total.
• Letting large bills cluster just before payday.
• Running the everyday account close to zero with no buffer for the lowest week.

Questions to think about

• Which week of the month is hardest for you?
• Which bill dates could you move to make that week easier?

Try it: Map money by week

1. Draw four weeks and write in each income and each bill on its date.
2. Work out the balance at the end of each week.
3. Change one date or add a small buffer to lift the lowest week.

Words in this lesson

• Cash flow — The movement of money in and out over time — and the timing of it.
