How to Calculate an Independent Board Member's Compensation

When your lead investor asks you to add an independent board member, most founders have no idea what to pay them. When we faced this at BenchSci's Series D, our CFO built a model. Here's the framework — and the actual numbers.

As your company approaches its Series B, your lead investor will likely ask you to add an independent director to the board — someone with no material financial relationship to the company who can provide genuinely unbiased perspective and judgment.

Most founders have no idea what to pay them. When we were closing our Series D at BenchSci, our CFO ran a comprehensive analysis — pulling input from our investors, lawyers, and other late-stage companies — to answer that question properly. We built a model. Here's what we learned.


Equity, not cash

For private VC-backed companies that are still burning capital, options are the standard form of compensation. Cash is rare — investors almost never see it for EBITDA-negative companies — and for two good reasons.

First, you don't want your board to become a cost center. Startups at every stage need to manage burn, and equity is a clean way to compensate board members without adding to it.

Second, the upside from options dwarfs anything you could reasonably pay in cash. A meaningful equity grant in a company on the right trajectory is worth far more than any annual retainer. Options are the only logical choice for both sides.

That said, if a board member specifically asks for cash, a nominal amount is reasonable — around $2,500 per board meeting, with the equity grant reduced proportionally. And regardless of the equity/cash split, always cover expenses: travel, accommodation, and costs incurred while acting in an official board capacity. For a board member flying cross-country for quarterly meetings, this adds up.


How to calculate the right equity grant

For later-stage companies — Series B and beyond — the working assumption is that your independent board member should achieve a 3x return on their option grant. Based on our research across comparable companies in Canada and the US, the market standard for equity compensation is 0.1% to 0.125% of fully diluted shares, with monthly vesting over two years and acceleration on a change of control.

At earlier stages (pre-seed or seed), you may see grants as high as 1% to 2%. But for a company valued at hundreds of millions of dollars, 0.1% to 0.125% is the right range.

The target payout — what you're designing toward — is $1,000,000 to $2,000,000 for the board member. That's the number to anchor on when working through the model.


The model

We built a template to make this calculation straightforward. You can access it here.

Three assumptions to plug in:

Target share price uplift. We use 3x as the benchmark. You're hoping for more — but 3x is a fair and conservative anchor.

Number of options. Determine how many options are required to generate the target monetary payout at the assumed uplift.

Grant structure. In most cases, one large upfront grant with standard four-year vesting. In some cases, a second grant after 24 months if the relationship is working well.

Two inputs you'll need:

FDSO (fully diluted shares outstanding) — your current total share count including all options and warrants.

409a valuation — your most recent independent appraisal of common stock fair market value.

Plug those in and the model tells you the number of options and the percentage of the company that represents.


Most founders encounter this question once, scramble to figure it out, and end up either over-granting or under-compensating. Hopefully this gives you a starting point that's grounded in actual market data — so you can spend the negotiation talking about fit and contribution, not working out the math.
