From snapshot to live

A runway number is only useful if it's current.

A static calculator uses one cash number and one burn number — the numbers you typed in. By the time payroll runs Friday, both are stale. TreasuryFlow keeps them live.

Common questions

Runway, explained.

How is runway calculated?

Runway (months) = current cash balance ÷ monthly net burn. If you enter incoming receivables, we add them to your cash for the calculation since they reasonably arrive before zero. Runway-out date is today + (runway months × 30 days).

What counts as "cash"?

Operating bank balances + savings + money market funds (MMF) + short-duration treasuries you can liquidate within 30 days. Don't count locked-up CDs, restricted cash, or LOC headroom.

What's "net burn"?

Monthly cash outflows minus monthly cash inflows (revenue collected). If you collect $500K and spend $620K, net burn is $120K. Use the trailing 3-month average — single months can be noisy.

When is runway "healthy"?

Generally: under 6 months is critical (raise or cut now), 6–12 months is caution (tighten + plan a raise), 12–18 months is healthy, 18+ months is comfortable. Industry-specific norms vary — venture-backed SaaS often runs 18+, bootstrapped services firms can operate fine at 4–6.
