Net Burn & Runway Formulas

Transparent mathematical methodology explained in plain English.

Net Monthly Burn = Gross Monthly Expenses - Monthly Revenue | Runway (Months) = Current Cash / Net Monthly Burn

Estimates the number of months a business can survive before exhausting its cash reserves under current burn rate conditions.

Variables Explained:

  • Current Cash: Total liquid bank balance and short-term capital reserves ($).
  • Gross Monthly Burn: Total monthly cash outflows (salaries, server hosting, office, marketing).
  • Monthly Revenue: Total monthly cash collections and recurring customer receipts.
  • Net Burn: Gross Burn minus Monthly Revenue ($).
Real Project Example

$350,000 Cash Balance with $45,000 Monthly Expenses and $15,000 Monthly Revenue

Calculating net burn and runway duration.

Sample Project Inputs:
Cash Balance:$350,000
Gross Monthly Expenses:$45,000
Monthly Revenue:$15,000
Step-by-Step Calculation:
  1. Net Monthly Burn = $45,000 - $15,000 = $30,000 per month.
  2. Runway in Months = $350,000 / $30,000 = 11.67 months (~11.7 months).
  3. Zero Cash Milestone: Cash reserves depleted in approximately 11.7 months.
Calculated Answer:11.7 months of runway remaining at a net burn rate of $30,000/month.

What is the difference between Gross Burn and Net Burn?

Gross burn is the total cash your company spends each month regardless of income. Net burn is the actual net cash loss (Gross Expenses minus Monthly Cash Inflows).

How much runway should a seed-stage startup maintain?

Most venture investors recommend maintaining 18 to 24 months of runway at any given time. This provides 12 to 15 months to hit milestone KPIs plus a 4 to 6 month buffer to close your next funding round.

What does it mean if my runway is infinite?

If your monthly recurring revenue exceeds your total monthly operating expenses, your net burn is negative (cash-flow positive), meaning your cash reserves are growing without external funding.

When should a founder start fundraising for the next round?

Founders should begin formal investor outreach when they have 6 to 9 months of runway remaining, as institutional venture rounds typically take 3 to 6 months from pitch to wired funds.
