Seed Round Allocation Calculator

Plan exactly how to deploy your seed capital — and how long each budget line lasts.

The biggest mistake with seed capital is spending it wrong. Most seed rounds should be deployed primarily on product and engineering (50–60%) to reach the product-market fit milestone, with a lean go-to-market to test channels. Spending heavily on sales and marketing before product-market fit is the most common way to burn through seed capital without results.

The Formula

Budget per Category = Total Raise × Category %

In plain English

Multiply total raise by each allocation percentage. Engineers affordable = engineering budget / (avg engineer cost × 18 months).

Worked Example

$2M seed: 55% engineering = $1.1M, 25% GTM = $500K, 15% ops = $300K, 5% buffer = $100K. Engineering: ~4 engineers for 18 months.

How to Deploy Seed Capital

The best seed-stage companies spend 50–60% of their capital on product and engineering. The goal of the seed round is to find product-market fit, and that's a product problem, not a sales problem.

Reserve 25–30% for GTM only after you have evidence of what works. This means founder-led sales, scrappy marketing, and learning what channels have good unit economics before scaling them with capital.

Common Mistakes

⚠️

Spending 40%+ on sales before product-market fit

Scaling sales before PMF is the fastest way to burn seed capital. Sales reps can't sell a product that customers don't want. Achieve PMF first (measurable: NPS 40+, NRR 100%+, 3+ customers paying full price), then scale sales.

⚠️

No buffer for unexpected costs

Always retain 10% unallocated. Legal disputes, infrastructure emergencies, and critical hires happen at the worst time. A $200K buffer on a $2M seed round has saved many startups from a distressed bridge.

⚠️

Hiring senior executives too early

A CRO or CMO costs $25K+/month. At seed stage, these hires are often premature — you don't yet have the processes or data for them to manage. Hire senior GTM executives when you have a repeatable sales motion to scale.
