Consulting Runway Calculator

Consulting firms generate healthy gross margins, but lengthy enterprise procurement and Net-60 or Net-90 invoice settlement can starve a firm of liquid cash. Calculate your firm’s operating runway to manage partner draws safely.

Industry Benchmark Guidance (4–6 months):Management and technology consulting practices typically maintain 4 to 6 months of fixed operating expenses and baseline staff payroll in reserve. This protects the firm when large enterprise client approvals stall during fiscal year transitions.

Financial Calculation Methodology & Transparency

How the Runway Calculator Works: Mathematical Model & Assumptions

1. Static Cash Runway Formula

For businesses with steady revenue and predictable overhead, runway is determined by dividing liquid cash reserves by net monthly cash deficit:

Runway (months) = Available Cash ÷ Net Monthly Burn

2. Gross Burn vs. Net Burn

  • Gross Burn: Total cash disbursed each month (payroll, contractors, hosting, rent, utilities).
  • Net Burn: Gross monthly expenses minus total monthly cash revenue collections.
  • Break-Even: When Net Burn $\le$ $0$, cash runway is mathematically sustainable or infinite.

3. Dynamic Growth Projections & Interpolation

When revenue growth or expense inflation rates are enabled, the engine calculates month-by-month compound flows up to 60 months:

Ending Cash(m) = Beginning Cash(m) + Revenue(m) - Expenses(m)
Fractional Month = Beginning Cash(depletion) ÷ Monthly Net Burn

We linearly interpolate the exact day/fraction when cash reaches $0, avoiding arbitrary rounded whole months.

4. Client-Side Privacy Guarantee

Every financial computation executes exclusively inside your local browser runtime. No financial balances, revenue figures, or payroll numbers are sent to any remote server or database.

2

Tether Partner Bonus Draws to Actual Cash Collections

3

Charge Mobilization Fees on Advisory Engagements

Collect a 20–25% mobilization fee upon contract signature to cover consultant allocation costs upfront.
