What virtual assistance costs, and how to compare hourly vs retainer

You've just realised your inbox has 2,847 unread emails and your calendar is a maze of double-bookings. A virtual assistant sounds like the answer—but when you start getting quotes, the prices swing wildly. One VA quotes R250 per hour; another asks for R8,000 a month retainer. How do you know what you're actually paying for, and which structure makes sense for your chaos?

What hourly rates really hide

When a VA quotes an hourly figure, that's the visible cost. What's invisible is the minimum commitment, the ramp-up waste, and the admin tax built into their time.

Most VAs won't take single-hour bookings. They'll have a 5-hour, 10-hour or 20-hour monthly minimum. That minimum exists partly because setting up access to your systems, learning your workflows and context-switching between clients eats time. If you're paying for 10 hours upfront but your actual admin work only needs 6, you're funding those setup costs whether you use them or not.

There's also the invisible overhead: email chains to clarify instructions, back-and-forth on whether a calendar slot should be 30 or 45 minutes, time spent waiting for you to respond to a question before they can move to the next task. Some of this gets billed; some gets absorbed. Either way, it stretches the real cost of getting your inbox under control.

Hourly rates work well if your admin demand is genuinely unpredictable—a spike when you launch a campaign, quiet spells when you're in deep work. You pay only for what you use (above the minimum). The trade-off is that your VA may not remember all your preferences month to month if they're context-switching between you and five other clients.

How retainers flatten the picture (and what they don't cover)

A retainer is a fixed monthly fee for a guaranteed number of hours. The appeal is simplicity: you know the cost, you know roughly what's available, and your VA is familiar with your patterns.

Retainers typically include a range of hours—say, 20 hours a month—that roll forward if unused or are lost if over-delivered. The price per hour usually drops compared to ad-hoc billing because your VA has predictability and can plan their schedule.

What's crucial: clarify what's included. Does 20 hours cover email triage, calendar management and expense logging, or just the first two? If a crisis dumps 30 unread messages on your desk mid-month, does that eat into your retainer or does your VA bill overages? How are public holidays handled? If a public holiday falls in a retainer week, do you get hours credited back?

Retainers work best for steady, recurring admin. They're less efficient if your workload is choppy—you're paying for capacity you don't always use.

The hidden cost drivers that matter most

Both models get more expensive the faster you need the work done. If your inbox needs replies the same day, that's a premium versus "triage and draft responses by end of week." Timezone compatibility costs too. A VA in your timezone commands more per hour than someone working overseas, partly because real-time collaboration (you asking them to tweak a draft while you're on a call) is only possible if they're awake when you are.

Technical complexity adds cost. Managing your email with a simple forwarding system is cheaper than building custom filters, syncing three calendars and automating expense coding. The VA might not explicitly list this as a line item, but their quote reflects it.

Access and security also matter. A VA who uses shared credentials and your existing tools is cheaper than one who needs to set up encrypted vaults, VPNs, or integration platforms. Some of that cost is baked into the quote; some you'll pay separately to the tools themselves.

Finally, compare the onboarding cost. Some VAs front-load it (included in month one, no overage) and spread it across your retainer. Others bill separately. Ask directly: if the first month takes twice as long to set up as month two, how is that charged?

When comparing quotes side by side, don't just look at the hourly or monthly number. Note the minimum commitment, what's explicitly included, what counts as overtime, and whether the quote assumes you'll hand them a messy backlog or a clean system. A cheaper quote that hides handover fees or excludes certain tasks will cost you more in frustration than a higher quote that's transparent.

Strove can help you find VAs who break down their pricing clearly and let real clients see what they've covered before. That transparency makes comparison honest.
