Co-founder Equity Split Calculator

2
co-founders

4-year / 1-year cliff

Standard VC-backed model. 25% after year 1, rest monthly. Most common in India.

3-year / 1-year cliff

Faster vest — good for older founders or second-time founders with prior equity.

4-year / 6-month cliff

Shorter cliff for co-founders who've worked together before incorporation.

Milestone-based

Equity unlocks on MVP, revenue, funding milestones. Common for non-tech co-founders.

4-year vesting / 1-year cliff: You own shares on paper from Day 1 but “earn” them over time. If a co-founder leaves before Month 12, they get 0% of unvested shares. After Month 12, 25% vests immediately. Remaining 75% vests monthly over 36 months. The company can buy back unvested shares at par value (₹1–10/share).

Never do 50/50 without a tiebreaker

Equal splits create board deadlock. Use 51/49, or appoint an independent director as tiebreaker. Indian Companies Act requires a majority for most resolutions.

Sign a co-founder agreement first

Before MCA incorporation, document equity, IP assignment, roles, non-compete, buyback triggers. Lawyers charge ₹15,000–50,000 for this — worth every rupee.

Credit pre-incorporation work

If you worked 6+ months before incorporating, negotiate early vesting credit. Many Indian founder agreements allow a “pre-vesting” period for pre-incorporation contributions.

Reserve 10–15% ESOP before Series A

Indian Series A investors will insist on an ESOP pool created pre-money, diluting founders. Create it proactively at seed with a formal ESOP policy under Companies Act 2013.

This calculator provides a framework for equity discussions — not legal advice. Equity splits have significant legal and tax implications under the Indian Companies Act 2013 and Income Tax Act. Always consult a CA and startup lawyer before finalising your cap table.
