ESOP Pool Sizing Calculator — Hiring Plan & Dilution
Size your option pool bottom-up from the roles you plan to hire. Add each role's headcount and per-hire equity grant; the tool sums the grants, adds a buffer for refreshes and unplanned hires, and gives the recommended pool % of fully diluted equity — then converts it to a number of option shares against your cap table and shows the founder dilution. Benchmarks: early engineers 0.5–2%, VP/C-level 0.3–1.5%, mid-IC 0.05–0.3%; overall pools run ~10–20% across stages.
Size Your ESOP Pool from the Hiring Plan
Add the roles you expect to hire over ~18 months and the equity grant for each. Percentages are of fully diluted equity.

How to Use the Pool Sizing Calculator
- List planned roles for the next ~18 months — add a row per role type (founding engineer, VP, mid-IC, etc.).
- Enter headcount and the per-hire grant % for each role; use the benchmark table below if unsure.
- Set a buffer (default 25%) for refresh grants, counter-offers and unplanned hires.
- Optionally add your cap table — pre-pool fully diluted shares and current founder holding — to see the pool in shares and the founder dilution.
- Click Calculate for the recommended pool %, a stage sanity-check, the option-share count and the dilution.
CA Tip: Once you have a target %, model how each future round tops it up with the dilution impact calculator, and pressure-test the headline number against the pool size calculator.
Why Size Bottom-Up?
Most founders pick a round number — "let's do 10%" — and hope it covers hiring. Bottom-up sizing reverses that: you start from the actual roles you intend to hire, attach a market grant to each, and let the pool fall out of the plan. It ties the pool to need, so you neither starve the plan nor over-dilute.
The recipe: project ~18 months of hiring, multiply headcount by per-role grants, sum, then add a 20–30% buffer for refreshes and surprises. See Patron's ESOP pool size guide and the ESOP scheme design service for how this becomes a Board-approved scheme.
Recommended pool = Planned grants × (1 + buffer)
Founder dilution = Founder % × pool ÷ (100 + pool)
Grant & Pool Benchmarks (India)
| Role / Stage | Typical range |
|---|---|
| Early engineers (first hires) | 0.5% – 2% each |
| VP / C-level | 0.3% – 1.5% each |
| Mid-level IC | 0.05% – 0.3% each |
| Junior | 0.05% – 0.1% each |
| Pre-seed / bootstrap pool | 5% – 8% |
| Seed pool | 10% – 12% |
| Pre-Series A pool (post-money) | 12% – 15% |
| Series B+ pool | 15% – 20% |
These are market starting points, not rules — adjust for seniority, timing and the cash-vs-equity trade. Avoid over-granting early: five hires at 2–3% each can exhaust the pool before product-market fit. Vesting is typically 4 years with a 1-year cliff under Rule 12(6)(a). Once sized, the pool becomes part of a Board- and shareholder-approved scheme filed with the MCA, and startups recognised by DPIIT can plan the perquisite-tax deferral around it.

How the Pool Dilutes Founders
Creating or topping up the pool increases the fully diluted share count, so every existing holder's percentage falls — founders included. If founders hold 100% and a 12% pool is created, their combined stake falls to about 88%.
The catch at fundraising: investors usually require the pool to be created or expanded before their money goes in, so it comes out of the pre-money valuation and the dilution lands on founders, not the new investor — the "pool shuffle." Sizing accurately, with just enough buffer, is the defence. Patron's ESOP dilution math explains the mechanics.
Note: Creating the pool late — at a term sheet — weakens your position, since investors push it into the pre-money. A modest early pool, topped up each round, is usually cleaner.
A Worked Example
A seed-stage startup plans the next 18 months: 4 engineers at 0.75% each, 1 VP Engineering at 1.2%, and 6 mid-IC at 0.2% each.
- Engineers: 4 × 0.75% = 3.0%
- VP: 1 × 1.2% = 1.2%
- Mid-IC: 6 × 0.2% = 1.2%
- Planned grants = 5.4%
- + 25% buffer → recommended pool ≈ 6.75%
That sits comfortably below the 10–12% seed benchmark, leaving room to top up at Series A. On a 1,000,000-share cap table, a 6.75% pool ≈ 72,400 option shares, and founders holding 100% would dilute to about 93.7% after the pool is created.
Planning Top-Ups Across Rounds
A pool is not a one-time decision. Investors at each round typically push for the pool to be refreshed to a target percentage on the new, larger cap table — so a 12% pool that has mostly been granted out may need topping back up to 12–15% post-money at Series A. Sizing too generously early wastes founder equity; sizing too tight forces an expensive last-minute top-up at the term sheet.
The bottom-up discipline helps here too: re-run the plan at each stage for the next 18 months of hiring, and you get a defensible top-up number to negotiate from rather than accepting an investor's round figure. Recognition with Startup India and a clean cap table strengthen that position, and the fully-diluted convention used throughout — counting all shares, options and the unallocated pool, consistent with the SEBI-aligned market practice for equity negotiations — keeps everyone measuring the same way. Professional scheme drafting, in line with ICAI guidance on share-based payments, ensures the chosen percentage is converted to a defined number of options in the documents.
Tip: Model each round's top-up and the cumulative founder dilution with the dilution impact calculator before you sign a term sheet.
