Should You Take Equity as a Fractional Executive? The Cash-vs-Equity Math

Sooner or later a founder will offer you equity instead of part of your fee, usually framed as a chance to "share the upside." Sometimes that is a great deal. More often it is a discount dressed up as a partnership, and the only way to know which is to run the math.

Start with your cash benchmark

Before you can judge an equity offer, you need a number to measure it against: what you would charge for the same work in straight cash. This is your cash benchmark, and every equity conversation is really a question of how far below it you are willing to go.

For a fractional executive, that benchmark is usually a monthly retainer tied to one or two days a week. Most fractional operators charge somewhere between $5,000 and $15,000 a month for that kind of engagement, with senior CFOs, CTOs, and CMOs at larger or better-funded companies landing higher. Pin down your own all-cash figure first. If you do not know what you would charge with zero equity on the table, you cannot tell whether the equity is a bonus or a bribe.

The delta-from-cash framework

Here is the only equity question that matters: how much cash am I giving up, and what am I getting for it?

Say your cash benchmark is $10,000 a month and the founder offers $7,000 a month plus equity. Your delta from cash is $3,000 a month, or $36,000 a year. That $36,000 is the real price of the equity. You are not getting shares for free. You are buying them, in installments, out of income you would otherwise have banked.

Now the equity has to clear a simple bar: is it plausibly worth more than the cash you are forgoing, adjusted for the very real chance it ends up worth nothing? Frame it three ways.

• Full cash: charge your benchmark, take no equity, keep all the certainty.
• Full discount, no equity: if you would not work for $7,000 with nothing attached, the equity is the only reason you are considering it, so judge the equity on its own.
• Discount plus equity: the blended deal, where you are spending your delta to buy a stake.

If the equity cannot beat simply taking full cash and investing the difference yourself, it is not a real upside, just a way to lower your rate.

How much equity is actually normal

Fractional and advisory equity grants are smaller than people expect, because you are part-time and usually joining after the riskiest early days. These are typical, illustrative ranges, not guarantees, and they swing with stage, your seniority, and how much cash you are discounting.

Situation	Typical equity range	Notes
Advisory role, light touch	0.1% - 0.25%	A few hours a month, intros, occasional calls.
Fractional exec, some cash discount	0.25% - 0.75%	Most common band for a real operating role.
Fractional exec, deep discount or near-founder role	0.5% - 1%+	Heavy involvement, early stage, large cash sacrifice.

If you are doing real operating work and taking a meaningful cash cut, drifting below 0.25% rarely makes sense. Above 1% usually means you are closer to a co-founder than a fractional hire, and you should price and document it that way.

Vesting and the questions that decide the value

The percentage is almost meaningless without the terms around it. A 1% grant that vests over four years with a one-year cliff is a very different thing from 1% that vests as you serve. Before you weigh any number, get clear answers to these.

• Vesting schedule. Monthly over one to two years is common for fractional roles. A standard four-year schedule with a cliff is built for full-time staff and may not fit part-time work.
• Options or restricted shares. If options, what is the strike price, and what does exercising actually cost you?
• Dilution. Your percentage shrinks with every future round. Where does the company sit now, and how many rounds are likely?
• Preferences. In most exits, investors are paid back first. Common equity, which is usually what you hold, gets what is left.
• What counts as an exit. Acquisition, IPO, secondary sale. Many small companies never have a liquidity event at all.

The three documents every equity deal needs

A startling share of fractional and advisory equity is never properly papered. By many accounts only around 41% of these arrangements are fully documented, which means the rest live in email threads and good intentions. When the company gets acquired or the founder relationship sours, an undocumented promise is worth almost exactly nothing. Three documents protect you.

• A written engagement agreement or advisory agreement. Scope, time commitment, cash fee, and the equity grant, all in one place, signed by both sides.
• The grant document itself. The stock option agreement or restricted stock agreement that legally issues the shares, with the number, strike price, and vesting schedule spelled out.
• Board approval. Equity is issued by the company's board, not promised over coffee. Confirm your grant was actually approved and recorded in the cap table. If it is not on the cap table, it does not exist.

If a founder cannot produce these or will not commit to producing them quickly, treat the equity as worth zero and negotiate purely on cash. You can always paper a grant later, but you cannot retroactively make a verbal promise enforceable.

A simple rule of thumb

Take equity when you genuinely believe in the company, the cash discount is one you could afford to lose entirely, and the terms are documented. Decline it, or discount your rate far less, when the equity is being used to talk you down from your benchmark and the paperwork is vague. Equity should be the upside on top of fair pay, not the excuse for underpaying you.

However you split cash and equity, it helps to set both deliberately rather than accepting whatever a founder floats first. On ExecRoster you publish a profile, name your own rate and terms, and let companies come to you, so the cash-versus-equity conversation starts from your number instead of theirs, with no recruiter taking a cut of the difference.
