Payroll Reserve / Runway

Why this comes up

Working capital planning usually focuses on steady-state cash needs, but the sharper question is what happens if collections stall entirely, a major client disputes an invoice, a payer goes through a slow patch, or a receivable simply doesn't come in on schedule. Knowing your runway in payroll cycles, not dollars, is the number worth having before you ever need it.

How we calculated this

Payroll Cycles Covered = Available Reserve / Cash Requirement per Payroll Cycle

Worked example: a $250,000 available reserve, $62,500 cash requirement per payroll cycle.

Payroll Cycles Covered = 250,000 / 62,500 = 4 cycles

What this means

• This is a stress-test number, not a steady-state planning figure; it answers "how long could we survive with zero collections," which is a different and more urgent question than normal working capital sizing.
• A low number of cycles covered means the agency has very little cushion against a collections disruption, worth knowing before, not during, a cash crunch.
• This figure should inform how large a credit line or factoring facility you keep available as a backstop, not just what steady-state operations require.

Common mistakes

• Only checking this number reactively, after a cash concern has already surfaced, rather than tracking it as a standing metric.
• Using an outdated cash-requirement-per-cycle figure rather than your current, actual per-cycle payroll cost.
• Treating available reserve as everything in the bank, without excluding cash that's already earmarked for other near-term obligations.

Frequently asked questions

What counts as "available reserve"?

Cash and readily available credit genuinely free to cover payroll, not committed to other near-term obligations. Be conservative here; overstating it defeats the purpose of a stress test.

Where does "cash requirement per payroll cycle" come from?

Your actual per-cycle payroll outflow, the same figure used in Payroll Float / Working Capital.

How many cycles of runway is "enough"?

There's no universal answer; it depends on your client concentration and payment reliability. An agency with a few large, sometimes-slow clients generally wants more runway than one with a broad, reliable client base.

Limitations

This is a simple division, not a simulation; it assumes zero incoming collections for the full runway period, which is a worst-case stress scenario, not a forecast.
