Runway & round-size calculator
"How much should I raise?" — answered. Simulate your runway month by month, see if you're default alive, and get a recommended round size tied to a real milestone.
Frequently asked questions
How is my runway calculated?
We run a month-by-month simulation over 36 months: costs grow at your organic cost-creep rate (plus any hires you add on their start month), revenue compounds at your month-over-month growth rate, and cash is drawn down by the net each month. Runway is the month your cash hits zero — or “36+” if revenue outpaces costs first.
What does “default alive” mean?
Paul Graham's term: your revenue growth crosses your costs before you run out of cash, so on the current trajectory you'd reach profitability without raising again. If you're default alive with comfortable cash, the recommended raise can be zero — you'd raise to go faster, not to survive.
How is the recommended raise size derived?
It funds your cumulative operating gap through the milestone window (default 21 months — roughly 18 months of runway plus a 3-month raise process), net of your current cash, plus a 20% buffer, rounded to a clean amount. It's a planning estimate, not advice — adjust the milestone slider to see how the number moves.
