Add numbers to your CV. You have heard it so often it barely registers. So you did it. A percentage here, a pound sign there, maybe a “10+” tucked into a bullet. And the inbox stayed quiet.

That is frustrating, because you followed the advice.

Here is the part nobody mentions. The numbers were never the problem. A figure on its own is just a claim, and recruiters have read thousands of unsupported ones. They learn to skim past them.

After more than ten years in UK recruitment, rewriting CVs for everyone from school leavers to directors, I keep seeing the same pattern. The CVs that win interviews do not have the biggest numbers. They have numbers that come with context.

Why a Lone Number Falls Flat

Picture a hiring manager on a Tuesday afternoon, forty applications deep, with a cold cup of tea beside them. They reach “increased departmental sales by 40%”.

Three questions fire at once. From what level? Over how long? By doing what?

If your CV does not answer them, the number loses its weight. Worse, it starts to look like luck, or a stretch of the truth.

Good bullets close that gap. They show where things stood, where you took them, and what you did in between.

This is where most CVs lose the reader. It is also fixable in a single evening.

Finding Numbers in “Non-Data” Roles

Work in admin, HR, care, teaching or operations? You may be thinking, “That is fine for sales people, but nobody counts what I do.”

I disagree. Every role leaves a trail. You just need to know where to look.

• Time: Did you simplify a clunky routine? Work out the hours saved each week across the team.
• Volume: How many clients, tickets, enquiries or compliance checks did you handle in a busy month?
• Quality: Did errors fall, complaints drop or turnaround times improve?
• Avoided cost: Did your checks prevent a fine, a rework or a missed deadline?

If digging these out of old jobs feels slippery, a professional CV Editing service can ask the awkward follow-up questions that bring them to the surface. It is often easier when someone else asks, because you stop thinking, “That was just my job.”

You can get far on your own, too. For each task, ask yourself: “What would have gone wrong if I had not done this?” The answer is usually your number. A late invoice avoided. A complaint that never happened.

The CAMI Framework

Duty descriptions tell a reader what your job title implied. Achievements show what you personally changed. Use four building blocks:

• Context: the problem or starting point
• Action: what you did
• Mechanism: the tool, method or process you used
• Impact: the measurable result

Here is the difference in practice.

Before: Responsible for overseeing customer support and managing incoming tickets.

After: Inherited a backlog of 200+ overdue support tickets, introduced a three-tier triage system, and cut average resolution time from 48 hours to 6 while holding satisfaction at 96%.

The second version is under 30 words and answers every doubt a sceptical reader might have.

You will not always fit all four parts into one line. That is fine. Aim for three.

One warning: do not force it. If a bullet starts to read like a formula, trim it. CAMI is a checking tool, not a template to paste into every line.

The Interview Test Most People Skip

Every figure on your CV is a promise that you will be asked about it.

Interviewers love to say, “Tell me more about that 30% saving.” If you cannot explain how it was calculated, who measured it and what your part was, the number works against you. I have watched strong candidates go quiet at exactly this moment.

So run each figure through three checks:

• Source: Did it come from a report, a dashboard, or an email from your manager?
• Ownership: Was it your result, or the team’s?
• Explanation: Could you describe the calculation in thirty seconds?

Keep a private note listing each figure, its source and your role. It takes about twenty minutes, and it makes you sound calm and credible when the question lands.

One more habit helps. Pair percentages with raw numbers. “Grew client base by 50%” could mean two clients or two hundred. “Grew client base from 12 to 18 accounts (50%)” is honest, and it still sounds good.

When the Hard Data Is Gone

Maybe you left that job years ago. Maybe the figures were confidential. You can still write strong, truthful lines without inventing anything. Use markers of scale instead:

• Ranges: “Coordinated shift handovers for 8–12 technicians across three sites.”
• Frequency: “Audited data protection logs fortnightly, removing end-of-quarter compliance delays.”
• Footprint: “Rebuilt the internal training wiki, now the first reference point for 140+ regional staff.”

If you are estimating, say so with “approximately” or “c.” and round sensibly. Honest estimates survive scrutiny. Precise-looking invented figures rarely do.

Cut the Padding

Many recruiters give a first pass only a few seconds. If your best work sits under wordy lead-ins, it will be missed.

Swap passive openings for direct verbs:

• Instead of “Was selected to assist the senior leadership team with…”, write “Co-managed…”
• Instead of “Held responsibility for carrying out daily audits on…”, write “Audited daily…”

Starting each bullet with a verb pulls the eye down the page. It also quietly tells the reader you did the work rather than watched it.

Writing for People and ATS Together

Applicant Tracking Systems matter, but a person makes the final call. Satisfying both is simpler than it sounds.

Never paste a block of keywords into a footer. Weave the terms into your achievements, next to the results.

When a skill sits beside a measured outcome, software reads it as relevant and a human reads it as believable. That is the combination you want.

A Quick Self-Audit

Before you send anything, check each bullet:

• Does it open with a strong verb?
• Does it give a starting point or challenge?
• Does it carry a number, range or frequency?
• Could you explain it confidently in an interview?
• Have you removed filler like “assisted with” and “responsible for”?

Final Thoughts

Strong CVs are rarely written in one sitting. They get sharper every time you ask, “So what changed because of me?”

Do that for each bullet and your CV stops being a record of where you have been. It becomes evidence of what you can do next.
