One of the most practical questions business owners face when hiring a virtual assistant is simple: how many hours do I actually need? The answer determines whether you're hiring part-time or full-time — and that decision has meaningful implications for cost, continuity, and how you structure the working relationship.
In 2026, the VA market has matured enough that both models are well-established, with different services, pricing structures, and suitability profiles for each. This guide helps you make the right call for your business.
Understanding Part-Time and Full-Time in a VA Context
Unlike traditional employment, "full-time" and "part-time" in the VA world are more fluid:
- Part-time VA: Typically 10–25 hours per week. The VA may work for multiple clients simultaneously and is often structured as a flexible contractor engagement.
- Full-time VA: Typically 35–40 hours per week. The VA is dedicated to your business and may function more like an embedded employee, though still usually structured as a contractor.
The key variable isn't just hours — it's exclusivity and availability. A full-time VA is generally available during your business hours and treats your account as their primary commitment. A part-time VA is available for a defined window that you both agree on.
"Part-time is right for businesses with episodic or defined task loads. Full-time makes sense when there's enough consistent work to fill a full week — and enough value in having dedicated availability."
Cost Comparison in 2026
The financial difference between part-time and full-time engagement is substantial:
| Engagement Model | Hours/Week | Estimated Monthly Cost (Offshore VA) | Estimated Monthly Cost (US VA) |
|---|---|---|---|
| Part-time (10 hrs/wk) | 10 | $400–$800 | $1,200–$2,400 |
| Part-time (20 hrs/wk) | 20 | $800–$1,600 | $2,400–$4,800 |
| Full-time (40 hrs/wk) | 40 | $1,600–$3,200 | $4,800–$9,600 |
These figures vary significantly based on location, skill level, and the nature of the work. For a complete breakdown of what VA services cost, see how much does a virtual assistant cost.
One important nuance: some VA agencies and services offer dedicated full-time rates that are lower than the simple multiple of hourly rate, since you're committing to consistent volume. Shopping around and comparing monthly retainer pricing versus hourly rates is worthwhile.
When Part-Time Is the Better Choice
Part-time is the right model when:
Your workload doesn't fill 40 hours. Be honest about this. Many business owners overestimate how much work they have to delegate when they first hire. Starting part-time and expanding if needed is smarter than paying for hours you're not filling.
Your needs are episodic or project-based. Some businesses have bursts of VA-worthy work — during launches, events, or seasonal peaks — and quieter periods. A part-time structure with flexible hours matches this reality.
You're testing the relationship. If this is your first VA hire and you're still figuring out how to delegate effectively, starting with 10–15 hours per week gives you a lower-stakes environment to build your management skills and systems.
Budget is a constraint. There's no shame in starting where your budget allows. A well-utilized part-time VA at $1,000/month delivers more value than a full-time VA you're scrambling to fill with work.
The work is specialized. If you need a specific skill (graphic design, bookkeeping, SEO) for a defined scope of work, part-time engagement is usually the right structure.
When Full-Time Is the Better Choice
Full-time makes sense when:
You have consistent, full-week work to delegate. If your VA workload genuinely fills 40 hours — inbox management, project coordination, research, content production, customer service — paying for dedicated full-time availability is efficient.
Availability and responsiveness matter. A full-time VA is more reliably available during your business hours. If you're a fast-moving business where questions need answers quickly and tasks need to be acted on same-day, full-time availability is valuable.
You want depth over breadth. A full-time VA can become deeply embedded in your business — learning your systems, your clients, your communication style. That institutional knowledge compounds over time in ways that a part-time engagement doesn't allow to the same degree.
You're replacing a function, not just reducing your personal workload. If the VA is taking over operations that currently require a dedicated team member — managing a customer support queue, running your marketing, handling all administrative functions — full-time scope is appropriate.
The cost savings over in-house hiring are the justification. Compared to an in-house employee at $50,000+ per year, a full-time offshore VA at $18,000–$24,000 per year represents a significant operational efficiency. For a full comparison, see virtual assistant vs. in-house employee.
The Practical Starting Point
Most businesses starting with their first VA are better served by starting part-time. Here's why: delegating effectively is a skill, and building that skill takes time. Most new VA clients don't immediately know how to fill 40 hours productively, and paying for more time than you use creates a feeling that the investment isn't worth it.
Start with 15–20 hours per week. Document what you're delegating. Assess at 60–90 days whether you need more capacity. If you're consistently using all the hours and have more to delegate, expand. If you're not, you haven't over-committed.
Many business owners who start part-time find themselves naturally scaling to full-time within six to twelve months as they become more comfortable delegating and their VA takes on more ownership of business functions.
