Total Operational Outflow

Definition

Sum of cash actually paid for operating activities for the period — payroll and benefits, employer taxes, vendor payments (infra, tooling, contractors), sales and marketing spend, rent, professional services, refunds issued. Excludes financing activities (debt repayment, dividend payments) and investing activities (acquisitions, capex). Direct input to gross burn. Common pitfall: capitalized R&D and long-term capex sometimes get bucketed here; if so they distort gross burn. Keep this strictly operating-cash and surface investing/financing outflows separately so the board can see "ongoing cost base" vs. "discretionary capital deployment".

Why it matters

The denominator-side of net burn and the basis of gross burn — controlling the structural cost base is the lever most boards can directly act on between fundraises.

How it's calculated

Sum of operating-activity cash payments for the period. Equals gross burn × months_in_period when there are no working-capital re-classifications.

How to interpret it

Decompose by spend category each board cycle (payroll vs. infra vs. GTM) — a sustained shift toward GTM or infra usually signals a strategic decision worth explicit board endorsement. No single industry threshold for "good" — interpretation is always against ARR, revenue per FTE, and gross-margin context.

Total Operational Inflow

Sum of cash actually received from operating activities for the period — customer collections (subscription, services, transactional revenue), refunds claimed back from vendors, and any operating tax credits. Excludes financing activities (debt draws, equity proceeds) and investing activities (asset sales, investment income). This is the numerator-side of the net-burn equation, and the cash-basis counterpart to recognized revenue on the P&L. Common pitfall: companies sometimes book annual SaaS prepayments here as a single-month inflow, masking the underlying monthly run-rate — split lumpy items out or smooth over a trailing 3 months.

Gross Burn Rate

Average monthly cash outflow before any inflows are netted off — essentially the company's monthly cost base in cash terms. Tracked alongside net burn because net burn alone can mask a structural problem when revenue is masking high cost. The board reads gross burn to understand the absolute cost commitment (mostly payroll, infra, COGS, sales spend) regardless of revenue mix. Common pitfall: founders often optimize the net burn narrative ("we cut burn 30%") via a one-time inflow without addressing the gross-burn cost base — the next quarter without that inflow re-exposes the underlying spend. Always present gross and net side-by-side.

Net Burn Rate

Average monthly net cash outflow over the reporting period — total cash spent minus total cash collected, divided by the number of months in the period. The headline survival number for venture-backed startups: it pairs with `finance.total_cash_in_bank` to produce runway, and pairs with revenue growth to produce the Bessemer "burn multiple". Common pitfall: net burn is volatile — large quarterly bills (annual SaaS renewals, employer-tax true-ups), enterprise prepayments, and FX swings can mask the underlying trend. Smoothing over a trailing 3-month average is standard board practice. Equally important: do not silently include one-off cash events (acquisitions, settlements, large prepayments received) without flagging them — boards prefer a "core burn" and "headline burn" pair when the period is noisy.

ARR per FTE

Annual Recurring Revenue divided by total FTE-equivalent workforce — the canonical SaaS workforce-productivity ratio anchored to the SaaS Capital Annual Survey methodology (revenue per employee benchmarks). A high-signal denominator for "are we over- or under-staffed for our revenue scale?" Common pitfall: choosing different ARR conventions (ending vs average, GAAP-reconciled vs raw) without locking in a board-level standard. Best practice is to pair this with `sales.arr` so the numerator is unambiguous and to disclose whether contractors are included in the FTE denominator.
