What is Runway (Financial)?

Runway — liquid cash divided by monthly burn, excluding owner draw — is the line between strategic agency and tactical desperation, with 6-12 months as the target zone.

Runway is the single number that tells a consultant how long the business could survive with zero new revenue: divide liquid cash by monthly operating burn, excluding the owner's own draw, and the result is a count of months. It is a strategic-horizon metric, not an operational one — where cash flow forecasting, its companion concept, answers whether next month's bills will clear, runway answers how much genuine freedom a consultant has to say no. For a freelance SAP analytics consultant, that freedom is not abstract: it is the difference between choosing engagements on fit and rate, and accepting whatever appears next because rent is due.

The formula and what belongs in it

Runway in months equals liquid cash divided by monthly operating burn. Liquid cash means money genuinely available on short notice — bank balances and instantly accessible reserves. It excludes illiquid assets such as stocks or real estate, and, importantly, excludes invoiced-but-unpaid receivables, since those are not yet cash and may arrive late or not at all. Monthly operating burn means recurring fixed costs — software subscriptions, professional indemnity insurance, accounting fees, escrow, office costs — plus averaged variable costs. The owner's personal draw is deliberately excluded from the burn figure: runway measures whether the business entity can survive, not whether the consultant's personal lifestyle can survive, and conflating the two produces a number that answers neither question well.

The four tiers

Why it matters

Below 3 months of runway, every engagement decision is rate-driven and the consultant can't afford to walk from bad terms — a structurally weak negotiating position.
Business runway (in the SASU/EURL/Ltd) and personal runway (household savings) draw from different pools and are routinely confused — lifestyle survival needs both funded.
Each €100/month cut from operating burn adds a full month of runway — a direct, measurable lever consultants control more easily than revenue.

Key points

Formula: liquid cash / monthly operating burn (excludes owner draw).
Tiers: <3mo desperation · 3-6mo survival · 6-12mo strategic · >12mo abundance.
Target: 6-12 months for strategic agency.
Provision corporate tax (25-30%) before counting as runway — phantom runway otherwise.
Personal and business runway tracked separately.
Invoiced-but-unpaid = cash flow (C069) not runway.
Under-draw fat quarters; cycle to maximum = stuck at 1-month runway.
Quarterly recalc minimum; monthly during market shifts.
Runway (Financial) is mastered only when it changes a named buyer decision.
Start with the semantic contract and control model before demonstrating the tool.

Terms used on this page

Runway: Months of operation possible if revenue stops today, at current operating burn.
Liquid cash: Bank balance + immediately-available reserves. Excludes invoiced-unpaid, illiquid assets.
Monthly operating burn: Recurring fixed + averaged variable costs, EXCLUDING owner draws. Measures business survival.
Strategic tier (6-12 mo): Runway zone where consultant can refuse 2-3 bad engagements, invest in differentiation, negotiate from confidence.
Phantom runway: Apparent runway that disappears when un-provisioned corporate tax bill arrives. Anti-pattern.
Tax provision: Reserved cash (25-30% of forecasted profit) for upcoming corporate-tax installments. Never count as runway.
Owner draw: Salary or dividends taken from corporate vehicle. Excluded from operating burn so runway measures business survival.
Personal runway: Household-level runway protecting consultant's lifestyle. Separate from business runway.
