Weekly cash flow forecast: catch a crunch while there is still time to act

Monthly forecasts react too slowly for a tight account. A weekly cash flow forecast — the 13-week rolling view businesses use — gives you the same early warning for your personal finances: enough lead time to move a payment, delay a purchase, or chase an invoice.

Start a weekly forecast

  • Week-by-week projection

    See the projected balance at the end of every week for the next three months.

  • Recurring items once

    Weekly, biweekly and monthly items all project forward automatically.

  • Early warning

    A shortfall four weeks out is a plan; a shortfall tomorrow is a crisis. The forecast gives you the former.

  • Ask your numbers questions

    Pro AI reads your ledger so you can ask "when is my next tight week?" in plain language.

The 13-week rhythm

Businesses run 13-week forecasts because a quarter is close enough to act on and far enough to matter. The same horizon works personally: three months of weekly balances shows seasonal dips, bonus paychecks, and the quarter-end bills that always surprise you.

Each week you check the projection, mark what actually happened, and the forecast rolls forward. Five minutes a week keeps it honest.

What to review each week

  • Did income land when the forecast said it would?
  • Which bills are due before the next payday?
  • What is the lowest projected balance in the next 90 days?
  • Any one-off items worth adding before they hit?

Frequently asked questions

How is a weekly forecast different from a monthly budget?

A budget plans a month as a whole; a weekly forecast shows the projected balance at the end of every week, exposing timing gaps that monthly totals hide.

Is a weekly forecast worth the effort?

It takes about five minutes a week once recurring items are entered, and it is the difference between planning around a crunch and discovering it on the day.
