Audit your capital consumption. Calculate Gross and Net burn rates for runway planning.
Step-by-step breakdown of monthly burn rate.
The Burn Rate Auditor calculates a startup's Gross and Net cash burn rates. Monitoring these metrics is essential for financial runway forecasting, board reporting, and determining the optimal timing for equity financing or debt facilities.
Worked Example:\nA seed-stage technology startup employs 8 engineers with monthly payroll and benefits totaling $85,000, AWS hosting of $12,000, office and software tools of $8,000, and growth marketing of $15,000. Customer subscriptions bring in $50,000 in monthly recurring collections:\n• Gross Monthly Burn: $85,000 + $12,000 + $8,000 + $15,000 = $120,000/month\n• Cash Inflows: $50,000/month\n• Net Monthly Burn: $120,000 − $50,000 = $70,000/month\n• With a current bank treasury balance of $1,050,000, the startup has: $1,050,000 ÷ $70,000 = 15.0 Months of Cash Runway.
If your Net Burn is positive, your bank balance is decreasing monthly. Venture capital best practices advise starting your next fundraising round when you have between 6 and 9 months of runway remaining, because closing an institutional venture round takes an average of 4 to 6 months.
Gross Burn represents the absolute total amount of cash spent each month, regardless of revenue. Net Burn is the difference between cash expenditures and incoming revenues—it represents the actual net depletion of your company's bank account.
Gross Burn reveals your cost structure vulnerability. If customer churn spikes or a major enterprise account cancels, your net burn can instantly jump up to your gross burn rate. High gross burn requires substantial revenue to sustain.
Early-stage startups typically budget for 18 to 24 months of runway following a funding round. This provides 12 to 15 months to achieve core product and growth milestones and 6 to 9 months to negotiate the subsequent Series A or B round.
Founders typically reduce net burn by renegotiating annual software contracts, auditing cloud infrastructure instances, deferring non-essential executive hires, and shifting sales incentives toward upfront annual cash collections rather than monthly billings.
Not necessarily. GAAP accounting includes non-cash items (such as depreciation, amortization, and stock-based compensation) and recognizes deferred revenue on an accrual basis. Burn rate tracks actual cash entering and leaving the bank account.
