How to Calculate Your Fundraising Ask and Use of Funds
Stop picking a fundraising number out of thin air. This guide gives you the bottom-up and top-down framework for calculating exactly how much to raise, with tactical budget advice, dilution math, and an investor-ready 'Use of Funds' slide template.
TL;DR: Calculate your startup's fundraising ask with a bottom-up budget for an 18-24 month runway, including a 20% buffer. Sanity check this number against market comps and a 15-25% dilution target. Your final 'ask' must be a single number tied to specific, measurable milestones that de-risk the business for the next round.
Key takeaways
- Build your ask from a bottom-up budget for an 18-24 month runway.
- Your three main cost drivers are People, Growth, and G&A.
- Add a 15-20% contingency buffer to your total projected burn.
- Test your ask against a 15-25% dilution target to find your implied valuation.
- Your 'Use of Funds' slide must connect the capital to measurable milestones.
- Never state your ask as a range; have conviction in a single number.
Your Ask Is a Strategic Plan, Not a Guess
Your fundraising "ask" isn't just a number on a slide; it's the financial expression of your strategy. Picking a number because it "feels right" or matches a competitor's last round is a fatal, amateur mistake. Investors see a weak, unsubstantiated ask as a clear signal of an operator who can't plan.
A strong ask is built from the ground up. It's a credible, bottoms-up plan that you can defend under pressure. This is how you build one.
The Goal: Fund Milestones, Not Just Time
The sole purpose of a funding round is to buy enough time to hit the milestones required to raise the next round at a significantly higher valuation. You are raising money to prove your next set of assumptions and systematically de-risk the business.
For most pre-seed and seed-stage companies, you need to fund 18 to 24 months of runway.
- 12-15 months to execute your plan and achieve your target milestones.
- 6 months for the fundraising process itself. It always takes longer than you think, and you can't run out of cash mid-process.
- 3-6 months of buffer. This is not slush for perks; it's your survival fund for when a key hire quits, a marketing channel dries up, or a market downturn freezes funding. In a tough market, 24 months is the default.
Step 1: Build Your Ask from the Bottom Up
Your ask is the sum of your planned expenses over your desired runway, plus a buffer. Open a spreadsheet. This is your operating plan, and it has three core components: People, Growth, and Operations.
Part A: Model Your Headcount Costs
Payroll is your biggest expense. List every role you will hire over the next 24 months, their target start month, and their fully-loaded cost. A safe estimate for fully-loaded cost (benefits, payroll taxes, etc.) in the US is 1.25x to 1.4x base salary.
On Founder Salaries: Pay yourself. Investors expect it. Starving yourself creates desperation and bad decisions. Post-raise seed-stage founder salaries typically range from
