Investor-Grade ARR Waterfall, Burn Multiple, and Runway for SaaS

Use Level observations as cross-trade context. Other cards are planning scenarios, not measured industry percentiles. Match your business model, period and cost definition before comparing.

Net Revenue Retention: Planning inputs to test, not measured industry percentiles: Planning comparison; SaaS percentile not established here. Below 100% means the existing-customer revenue cohort shrank before new-customer sales; total company revenue can still grow.

Gross Margin: Planning inputs to test, not measured industry percentiles: A 75-85% gross-margin sensitivity, not an observed SaaS percentile. Define hosting, support, third-party services and inference costs consistently before comparing products.

Magic Number: Planning inputs to test, not measured industry percentiles: A 0.7-1.0 sensitivity. State the chosen ARR-change and sales-and-marketing spend periods; other magic-number conventions differ. Above 1.0 is not permission to scale without collection, retention and gross-profit checks.

Burn Multiple: Planning inputs to test, not measured industry percentiles: Test under 1.5x and a separate under-1x case. Net burn / net new ARR requires matched periods and positive net new ARR; neither is an asserted investor requirement.

Rule of 40: Planning inputs to test, not measured industry percentiles: A planning convention: matched annual revenue-growth percentage plus free-cash-flow-margin percentage. Define recognized revenue versus ARR and free cash flow before comparing; 40 is not proof of cash availability.

CAC Payback: Planning inputs to test, not measured industry percentiles: Test under 18 months with separate 12- and 24-month sensitivities. Define acquisition cost, new-customer gross profit and cohort timing; these are not sourced quartiles.

We reconcile your billing system, CRM, and general ledger every month so your ARR bridge ties out to the penny. Annual recurring revenue (ARR) needs a defined eligible-contract population and reporting cutoff. A blended total does not explain the movement: reconcile opening ARR, new sales, expansion, contraction and churn to closing ARR before interpreting growth.

We lock in clear, auditable metric definitions with you and your board so every update is fast and defensible. Agree reporting definitions with your board: net revenue retention (NRR) follows existing-customer revenue including expansion, contraction and churn; gross revenue retention (GRR) excludes expansion. Magic number relates new recurring revenue to sales-and-marketing spend. Acquisition-cost payback asks how long customer gross profit takes to cover the acquisition cost. Define each metric's period, numerator and denominator and reconcile its inputs. Set the reporting cadence with your board instead of assuming every company needs the same deck.

We keep your cap table records, asset tests, and tax filings coordinated with your legal and tax advisors early. Before issuing founder stock, confirm the actual entity, original issuance, qualified-business activity and asset tests. Holding-period and acquisition-date rules affect any later QSBS exclusion; C-corp formation alone does not guarantee it. Keep stock documents and tax review connected to the cap table.

Level brings approved books, payroll and infrastructure-spend exports or supported connections together to track gross profit for a defined period divided by logged engineering hours (a Level operating measure, requiring time records or a disclosed allocation; not a standard SaaS metric), burn multiple and runway on the cadence those records support, so every engineer hour goes to the product, not the spreadsheet.

Calculate net and gross revenue retention (NRR and GRR), magic number, acquisition-cost payback and Rule of 40 using definitions agreed with your company and board. Work from customer relationship management (CRM) and billing exports or supported connections you authorize; Level’s team reviews the population and calculations.

Our buyer-side investment committee (IC) experience informs the questions we help you prepare for; your actual investor determines what evidence is needed and whether terms change.

It requires qualifying original-issue C-corp stock, an eligible business and shareholder, applicable asset tests and the required holding period. For stock acquired after July 4, 2025, the phased exclusion is 50% after 3 years, 75% after 4 years and 100% after 5 years; the per-issuer exclusion limit is the greater of the applicable $15M dollar limit or 10 times qualifying basis, with prior-exclusion coordination and other limits. Earlier stock uses different rules, including the older $10M limit. Formation alone does not secure eligibility; we coordinate records and tax review before issuance or an exit.

Trace qualifying activities to payroll and contract expenses, then confirm group eligibility, receipts history and the timely Form 6765 election before a payroll-tax offset. Custom software alone is not proof of qualification.

A 4.5-5% yield is a fictional sensitivity, not a current quote from Mercury, Ramp or Rho. At illustrative $5M invested for a full year at 4.8%, gross interest is $240K before fees and taxes; changing balances or rates changes the result. A $10M balance at 4.5-5% would yield $450K-500K on the same assumptions. Check current terms and access before moving cash; income is not a guaranteed engagement payback.

An 83(b) election chooses to recognize income on qualifying nonvested property at transfer and must be filed no later than 30 days after that property transfer. Review incentive stock options (ISO), alternative minimum tax (AMT) and residency rules under your actual facts. An S-corp election generally conflicts with C-corp QSBS and venture financing; entity choices must fit the actual funding and exit plans.
