Work out funding requirement instantly with clear inputs, formula shown and shareable results.
Size a round from the runway you need to reach the next milestone, not from what investors might offer. Multiply net monthly burn by the target months, add committed capital spend, then add a contingency — plans slip, and running out of cash while fundraising destroys valuation.
Funding required
Funding = (Monthly net burn x Months + Capex) x (1 + Contingency %)
Implied runway
Runway = Funding / Monthly net burn
18-24 months is the common target: enough to hit milestones and still have six months of cushion to run the next process.
Net burn, after revenue receipts. Gross burn overstates the requirement for any company with meaningful revenue.
