Executive Assistant KPIs That Show What Your EA Is Worth

Is your executive assistant really helping you reclaim 15 hours of your time weekly, or are you simply paying for inbox Your executive assistant can stay busy all day while your own week looks exactly the same. Executive assistant KPIs show you whether their work is actually giving you time back.

The right KPIs measure what your EA takes off your plate, how reliably they deliver it, and how well they represent you. Counts of emails sent or calls returned can’t tell you any of that.

We spent our careers as executive assistants to CEOs before we built ProAssisting. Below are the eight KPIs we trust, how to measure each one, and how to set them up without micromanaging your assistant.

TL;DR: Executive Assistant KPIs in Brief

Here’s what you need to know about measuring your EA:

• Good EA KPIs measure the time and outcomes you get back.
• The most important KPI is the number of hours your EA returns to you each week.
• Reliability KPIs track response time, calendar accuracy, and on-time follow-through.
• Representation KPIs track how many requests go to your EA first and how your contacts rate the experience.
• Three to five KPIs are enough to start. Measure a two-week baseline before you set targets.
• Your own inputs, such as delegated access and shared priorities, shape every number on the list.
• A fractional EA is measured on the same KPIs, against the standard set in your agreement.

What Executive Assistant KPIs Should Measure

A KPI, or key performance indicator, is a number you track over time to see whether something is working. For an executive assistant, the thing that should be working is your week.

Your EA’s job is to give you back time and to represent you well while doing it. Every KPI you choose should connect to one of those two results.

A lot of executives still judge their EA by activity numbers. But an EA who answers 300 emails a day hasn’t helped you if you still read all 300.

So what makes a KPI useful? Good EA KPIs share three traits:

• Tied to your outcomes: Each one shows a change in your workload, your schedule, or how people experience your office.
• Simple to count: You can pull the number from your calendar, inbox, or a shared tracker in a few minutes.
• Agreed with your EA: Your assistant knows the target and helps you track it. The number never comes as a surprise to either of you.

8 Executive Assistant KPIs Worth Tracking

These eight KPIs cover the time, reliability, and representation results that matter most to you:

1. Hours Returned to You Each Week

Every other KPI on this list adds up to this one. If your EA is doing the job well, you should be able to name the hours you got back and what you did with them.

You can track it in two steps:

• List what you’ve handed off: Write down the recurring work your EA now owns, such as scheduling, travel booking, inbox triage, and expense reports.
• Estimate the hours: Note how long each item used to take you per week. Add the hours up once a month.

You can also put a price on those hours. In The 29-Hour Work Day, ProAssisting co-founders Ethan and Stephanie Bull suggest a simple formula. Divide your annual net profit by 2,080, the number of working hours in a 40-hour, 52-week year.

Your pay works as a quick benchmark too. Chief executives earned a median of $213,990 in May 2025, or about $103 an hour.

At that rate, five hours back each week is worth roughly $26,750 a year.

Expect the number to rise over your first few months. It levels off once the obvious handoffs are done.

2. Share of Your Inbox Handled Without You

Open your inbox on a Monday morning. If you’re still sorting vendor pitches, meeting requests, and FYI threads yourself, that work hasn’t been handed off yet.

Here’s how to track it:

• How to measure it: Compare the number of emails that reach your priority folder each week against the total that arrived. Your email search and filter tools can pull both counts in a few minutes.
• What good looks like: The share should climb each month as your EA learns who matters to you. It keeps rising as they learn how you like each type of message answered.

3. Calendar and Meeting Prep Accuracy

You walk into a 10 AM call and realize you don’t know who two of the attendees are. That’s a prep miss. It belongs on your scorecard next to any double-booking.

Keep a running tally of these misses in a shared note:

• Scheduling errors: Count double-bookings, wrong time zones, and meetings booked into time you protect.
• Prep gaps: Count external meetings that start without an agenda, attendee background, or call details in the invite.

A few misses are expected while your EA learns your preferences. A miss that repeats usually means your EA needs a rule from you, such as “never book over my Tuesday workout.”

4. Response Time During Business Hours

Picture a client who needs a revised deck before a 3 PM call. Response time tells you whether you can count on your EA in moments like that.

Set it up in three steps:

• Put the standard in writing: Agree on a reply window for normal requests. ProAssisting, for example, commits to daily replies within an hour or less during business hours.
• Define urgent: Decide how you’ll flag a request that can’t wait. A call or text can signal urgency, while an email can wait for the normal reply window.
• Spot-check weekly: Note the send and reply times on a handful of requests. Flag only the misses that actually mattered.

5. On-Time Follow-Through

If you keep asking your EA where a task stands, you’re still tracking work you thought you’d handed off.

Follow-through measures the share of commitments your EA delivers by the promised date, without a reminder from you.

A simple handoff log makes it easy to track:

• Log each handoff: Note the task, the date your EA promised, and the date it was done.
• Review it monthly: Count the items that slipped and talk through why.

A missed date often traces back to shifting priorities or a deadline nobody set. Check for those causes before you treat a slip as a performance issue.

6. Projects and Travel Run End to End

A board retreat is a good test. If you’re still picking hotels and chasing RSVPs, the project hasn’t really left your desk.

A project counts as owned when your EA plans it, runs it, and handles the problems that come up along the way. Good examples are an office move, a three-city conference trip, or a family vacation.

Track two numbers each quarter:

• Projects owned: Count the projects and trips your EA ran from start to finish.
• Times you stepped in: Count how often you had to get into the details yourself.

A rising project count with fewer step-ins shows your EA is taking on bigger work.

7. Requests Routed Away From You

Your direct report has a question about Thursday’s board packet. Your EA should answer it before the question ever reaches you.

Routed requests show how well your EA works as your single point of contact for clients, direct reports, vendors, and family.

Each week, count the status questions, scheduling asks, and document requests your EA resolved on your behalf. Over time, fewer of those questions should land in your inbox or on your phone.

8. Stakeholder Feedback on How Your EA Represents You

Your board chair, your biggest client, and your team all deal with your EA. How they feel about those interactions becomes part of how they feel about you.

A light survey twice a year is enough:

• Pick three to five people: Choose regular contacts who work with your EA often.
• Ask two questions: Have them rate your EA’s responsiveness and professionalism on a 1-to-5 scale.
• Leave room for comments: A short comment box often tells you more than the scores.

Between surveys, jot down unprompted compliments and complaints as they come in.

How Each KPI Maps to Your EA’s Five Roles

We describe a high-level EA’s work through five Performance Multipliers, which are the five roles one EA can fill for you.

Mapping your KPIs to those roles shows which parts of the job you’re measuring and which parts you’ve left out:

In this framework, chief of staff means a single point of contact for your contacts. It’s a different job from the traditional chief of staff who owns company goals and KPIs.

If a role has no KPI next to it, you’re probably not delegating that part of the job yet.

The Inputs Your EA Needs From You

Every KPI on this list depends partly on you. Your EA can only hit a target if you’ve given them the access and information the work requires.

These inputs make the biggest difference:

• Delegated access: Your EA needs access to your email, calendar, and contacts to manage them. Without it, your inbox and calendar KPIs measure a job they can’t fully do.
• Context about your world: Share your key clients, board members, family members, travel preferences, and the meetings you protect. The more your EA knows, the fewer questions reach you.
• Clear priorities: Tell your EA what matters most this week and what can wait. A weekly priorities check-in keeps their judgment calls aligned with yours.
• Room to decide: Trust your EA with routine decisions from day one. An EA who needs your sign-off on every step can’t improve their numbers.
• Honest feedback: Tell your EA right away when something works or misses. Feedback held until a formal review comes too late to change the result.

If a KPI stalls, check these inputs before you judge your assistant’s performance.

How to Set Up EA KPIs Without Micromanaging

KPIs work best when your EA helps build them and you both see the same numbers. These five steps keep the process light:

1. Agree on the Outcome You Want

Start with one sentence about what you want from the partnership. It might be ten more hours a week for sales calls or a calendar you never have to fix.

Every KPI you pick should support that sentence.

2. Record a Two-Week Baseline

Before you set targets, track the current numbers for two weeks. Note the hours you spend on tasks you plan to hand off, the calendar errors you catch, and how long requests take to come back.

If your EA is new, run the baseline during your EA’s onboarding. You’ll be able to see progress from the first month.

3. Pick Three to Five KPIs

Choose the KPIs tied to your biggest pain points. If your calendar is chaos, start with calendar accuracy and response time. If you’re buried in email, start with inbox share and hours returned.

Resist the urge to track all eight at once. That turns measurement into paperwork for both of you.

4. Track Them in One Shared Place

Keep the KPIs in a single document or spreadsheet that you and your EA can both open. Ask your EA to keep it updated, since they already see most of the data in your inbox and calendar.

5. Give Feedback in the Moment

Talk about a result when it happens, while the details are fresh. A quick note does more than a long annual review. Try “Thanks for catching that double-booking” or “The car went to the wrong terminal, so let’s add a check.”

Then use a short monthly check-in to look at the trends together. Our EA performance review examples show what those conversations can sound like.

How to Measure a Fractional or Remote EA

A fractional executive assistant works for you on a set share of their resources, paid through a flat monthly retainer.

A remote EA, fractional or full-time, works from their own office and stays in touch by email, phone, text, and video.

If you’re not sure which level of support fits you, our two-minute support assessment can help you decide.

The good news is that the eight KPIs above apply to a fractional EA without changes. But three points need extra attention:

• The response standard in your agreement: Measure response time against the standard your provider commits to in writing. That standard becomes your benchmark for KPI 4.
• The share of resources you use: ProAssisting’s pricing page lists plans at one-third, one-half, or two-thirds of a ProAssistant’s resources. If you regularly need more than your share, move up a tier, because heavy use reflects your workload and says nothing about your assistant’s performance.
• Ramp-up time: A new EA learns your preferences, contacts, and habits over the first few months. Judge each month against your baseline from step two.

One more number is worth asking any provider about. Ask how much of your retainer actually reaches the assistant. ProAssisting passes more than 75% of each retainer directly to the ProAssistant, according to the same pricing page.

Fair pay keeps experienced assistants in place long enough to build the knowledge your KPIs depend on.

KPI Mistakes That Undermine Executive Support

Even good KPIs can strain the partnership if you run them the wrong way. Watch for these mistakes:

• Tracking too many numbers: A dashboard of 15 metrics eats the time your EA could spend on your work. Keep the list short enough to review in ten minutes.
• Using KPIs to check every step: Numbers meant to show progress can turn into a tool for micromanaging. If you review each task your EA touches, the KPIs are costing you time.
• Setting targets that conflict: “Answer every email within ten minutes” and “Write thoughtful replies to clients” pull in opposite directions. Decide which one matters more for each type of message.
• Copying another company’s KPIs: A list built for a large corporate EA team won’t match a founder’s needs. Build your KPIs around your own baseline.
• Saving feedback for the annual review: A problem raised nine months later is hard to fix and even harder to remember. Address results while they’re fresh.

Frequently Asked Questions (FAQs)

Here are quick answers to common questions about executive assistant KPIs:

What Is the Difference Between EA KPIs and SMART Goals?

A KPI is a measure you track all the time, such as the share of requests answered within an hour. A SMART goal is a specific, measurable, achievable, relevant, and time-bound target, like one calendar error a month by June. You can see examples in our guide to executive assistant SMART goals.

Should Confidentiality Be an EA KPI?

Confidentiality works better as a standard than as a KPI. You expect zero breaches, so there’s nothing to improve on a scorecard. Cover it in an NDA and treat any breach as a serious issue.

Should an Executive Assistant’s KPIs Include Revenue?

Revenue targets usually make poor EA KPIs. Your EA affects revenue through the time they free up for your sales calls, clients, and strategy. Measure that time directly with hours returned.

Do KPIs Differ for Junior and Senior Executive Assistants?

Yes, the targets often differ. A newer assistant is usually measured on accuracy and response time. A senior EA should also own projects, field requests as your single point of contact, and represent you well.
