Calculate funding needs based on runway: Monthly burn rate × 18-24 months = minimum raise. For seed rounds, $500K-2M is typical; Series A averages $10-15M. Formula: (Team salaries + Operations + Marketing + Buffer) × 18 months. Never raise less than 12 months runway—you'll be fundraising again immediately. Add 20% buffer for unexpected costs.
