A contractor runs about $900/month per client. Agency pricing is quoted by seat count on a demo call. Here's where the real break-even sits, and what a contractor still does that a tool can't.

The alternative to adding a repurposing tool is usually hiring - a junior ghostwriter or a VA to handle client LinkedIn content by hand. Before committing to either path, the actual numbers are worth putting side by side, not just the per-hour rate.
A typical contractor handling one client's LinkedIn content - drafting, revising, chasing approvals - runs around $900 a month in billed time per client, once research, drafting, and rewrite cycles are all counted. That's not the contractor being expensive; that's what the actual hours cost at a normal freelance or junior-hire rate.
SparkVox agency accounts use volume pricing under one master billing account - per-seat cost decreases as you add clients, which is structured differently from buying individual Pro, Accelerate, or Scale seats for each author ($97-597/month depending on plan). Request a demo for a quote based on your roster size.
The comparison isn't close once you're running more than one client: one contractor's monthly cost can cover multiple agency seats before even accounting for the rest of the roster. The gap widens with every additional client added, since a contractor's time scales roughly linearly with client count while agency per-seat cost decreases.
The honest caveat: a contractor brings judgment a tool doesn't - strategy calls, campaign thinking, client relationship management. This isn't a full substitute for that role. It's a substitute for the drafting and revision hours specifically, which is usually the majority of what a junior ghostwriter or VA is actually billing for.
At one client, a contractor at roughly $900/month may still be competitive with tooling at small scale - the advantage isn't obvious yet. At five clients, contractor cost scales to roughly $4,500/month if hiring proportionally (or a single overworked contractor handling all five, with the quality risk that implies), against agency volume pricing that covers the same roster under one account - a gap worth running on a demo call. At fifteen clients, the contractor-scaling math requires multiple hires entirely, while agency per-seat cost keeps decreasing rather than multiplying.
The crossover point where the tool clearly wins isn't one client - it's roughly two or three, which is a lower bar than most agencies evaluating this expect going in.
Management overhead - onboarding a new contractor, reviewing their work quality, replacing them when they leave - isn't captured in the $900/month rate, but it's a real cost that scales with contractor count in a way agency per-seat pricing doesn't. A contractor roster of five has five relationships to manage; an agency account with five client seats has one account to manage, regardless of headcount.
