Financial Glossary
A 13-week cash flow forecast is a rolling, short-term projection that maps expected cash receipts and disbursements week by week over a 13-week (roughly one-quarter) horizon. Unlike an annual budget, it focuses purely on the timing of cash moving in and out, making it a tactical tool for managing liquidity. Each week the oldest period drops off and a new week is added, keeping the forecast continuously current.
Seasonal operators such as campgrounds, short-term rentals, and hospitality businesses lean on the 13-week forecast to bridge gaps between high and low revenue periods, since it shows precisely when cash will be tight enough to threaten payroll or vendor payments. Startups managing limited runway use it to time hires, payments, and fundraising against the actual week a balance would run low. Because it is granular and updated weekly, it surfaces problems early enough to act, well before they show up in monthly financials.
The 13-week cash flow forecast is the standard tool for managing near-term liquidity with precision. It keeps owners focused on the single question that determines survival: will there be enough cash each week.
