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.

Startup Runway Frequently Asked Questions

Everything you need to know about cash runway, burn rates, and financial planning.

VC-backed startups should ideally target 18 to 24 months of runway following a funding round. This gives founders 12 to 18 months to reach critical traction milestones (e.g. $1M ARR or proof of PMF) plus a mandatory 6-month window to pitch and close their next round.
