"Is my assistant worth it?" deserves a better answer than a gut feeling. Measuring the return on an assistant isn't hard if you track three things: the time you get back, the output they produce, and the quality of that output. Here's a simple, honest approach.
The ROI equation
At its simplest:
ROI = (value of time recovered + value of new output − cost) ÷ cost
Each part needs a sensible estimate.
Value of time recovered
Track how many hours a week you no longer spend on delegated work. Multiply by a value per hour. Two reasonable ways to set that value:
- Cost-based: your fully loaded compensation divided by working hours.
- Opportunity-based: what an hour of your best work produces — pipeline generated, deals closed, product shipped. This is usually higher and more meaningful, but harder to estimate.
Be conservative. If you're unsure, use the cost-based figure.
Value of new output
Some assistant work isn't something you were doing before — it's something that wasn't getting done at all. Examples:
- Target account lists that never got built
- CRM data cleaned so the forecast is trustworthy
- Books closed monthly instead of quarterly
- Follow-ups sent within 24 hours instead of "eventually"
This is harder to value directly. Track it anyway; it's often where the biggest impact lies.
Cost
The full cost includes the fee plus any tools you license for the assistant and your management time, especially in the first month.
A worked example (illustrative)
A VP of Sales values their time at $120/hour. A Revenue Assistant on a $2,300/month plan frees 8 hours a week.
- Time recovered: 8 hours × 4.33 weeks × $120 ≈ $4,160/month
- Cost: $2,300/month + ~$100 tools = $2,400
- ROI from time alone: ($4,160 − $2,400) ÷ $2,400 ≈ 73%
That's before counting new output like cleaner pipeline data or more meetings held. Your numbers will differ; the method is what matters.
The weekly scorecard
Track five to eight measures weekly. Keep it on one page.
Time
- Hours of delegated work this week (assistant logs)
- Your estimate of hours saved
Output (role-specific)
| Role | Output measures |
|---|---|
| Executive assistant | Meetings scheduled; briefs delivered; inbox items resolved |
| Revenue assistant | CRM records updated; verified contacts added; meetings booked and held |
| Operations assistant | SOPs written; recurring tasks completed on time; reports delivered |
| Bookkeeper | Accounts reconciled; bills processed; close completed by target day |
Quality
- Errors caught in review
- Rework requests
- On-time delivery rate
- Your satisfaction rating (1–5) for the week
Set baselines first
Measure the "before" in the first week: how many hours you spend on the work, how long reports take, how many deals have stale data, how many days it takes to close the books. Without a baseline, you'll be comparing against memory — and memory is a poor analyst.
Review cadence
- Weekly (10 minutes): look at the scorecard; discuss one improvement.
- Monthly (30 minutes): review trends; decide what to delegate next.
- Quarterly: recalculate ROI; decide whether to change scope or plan.
What good looks like over time
In the first month, expect ROI to be modest or negative — you're investing time in onboarding. By month two or three, time recovered should be consistent and new output should be visible. If it isn't, diagnose:
- Not enough delegated? Revisit your task audit.
- Too much rework? Improve SOPs and decision rules.
- Skills gap? Agree a training plan or ask your provider for support.
- Fit issue? With a managed provider, ask for a replacement.

Pitfalls in measuring
- Only counting cost savings. The value is usually in what gets done, not just what's cheaper.
- Overstating time saved. Be conservative; credibility matters.
- Ignoring quality. Speed without accuracy creates rework.
- Measuring too many things. Five to eight measures is plenty.
A worked example: a 90-day scorecard
Here's an illustrative scorecard for a VP of Sales with a dedicated assistant, measured weekly and summarized at 30, 60 and 90 days. The baseline is two weeks before the assistant started.
| Measure | Baseline | Day 30 | Day 60 | Day 90 |
|---|---|---|---|---|
| Hours/week the VP spent on admin (self-reported log) | 14 | 9 | 6 | 5 |
| Customer meetings held per week | 6 | 7 | 9 | 10 |
| CRM opportunities missing a next step | 38% | 25% | 12% | 8% |
| Pipeline review prep time (VP's own) | 2.5 hours | 1 hour | 30 minutes | 20 minutes |
| Follow-ups sent within 24 hours of meetings | ~50% | 80% | 95% | 95% |
| Expense reports submitted on time | Late most months | On time | On time | On time |
These numbers are illustrative, not results. Your scorecard should use your own baselines.
Turning hours into dollars, carefully
A common approach values recovered time at a loaded hourly cost:
Loaded hourly cost = (annual salary + benefits and payroll taxes) ÷ working hours per year
For example, a $220,000 salary with about 30% in benefits and taxes, over roughly 2,000 working hours, gives about $143 an hour. Nine recovered hours a week is about $1,287 a week, or roughly $5,500 a month in time value.
Time value is not cash savings. The return only appears if the leader uses the recovered hours on higher-value work. That's why the scorecard tracks outputs, such as customer meetings and pipeline quality, alongside hours.
The BLS Employer Costs for Employee Compensation release is a useful public reference for how much benefits add on top of wages.
Checklist: setting up the scorecard
- [ ] Pick 4–6 measures: two time measures, two output measures, one or two quality measures
- [ ] Record a two-week baseline before handing anything off
- [ ] Use data that already exists where possible: calendar, CRM, expense tool
- [ ] Have the leader log admin time for 10 minutes on Friday, not daily
- [ ] Review the scorecard together every 30 days
- [ ] Retire any measure that nobody uses to make decisions
What to do if the numbers don't move
- Hours didn't fall: the leader may still be doing the work, or tasks were handed off without clear "done" definitions. Revisit the delegation list.
- Hours fell, outputs didn't rise: recovered time is being absorbed by more meetings. Protect focus blocks on the calendar.
- Quality measures got worse: the SOPs need tightening, or the assistant needs more context. Review the work together.
Keep the scorecard on one page and in one shared document. If it takes more than 10 minutes a week to maintain, cut measures until it doesn't.
The bottom line
Assistant ROI is measurable: track time recovered, new output and quality weekly against a baseline, and recalculate quarterly. Most leaders find the exercise also improves delegation itself — because measuring forces clarity about what the work is.
