How to quantify achievements on a CV (even without obvious numbers)

Six places to find numbers for your CV, and how to estimate honestly when nobody measured.

Numbers make a CV bullet easier to believe and easier to picture. “Managed a large team” asks the reader to trust you; “managed a team of 14” lets them see it. The common objection is “my job didn’t have numbers”. Almost every job does. They are just not on a dashboard.

Six kinds of number

Work through these for each role. You will rarely use all six, but most people find two or three for every job.

1. Scale: how big was the thing?

How many customers, patients, students, products, sites, users, rooms, vehicles, accounts, records, lines of code, square metres?

Before: Managed the company’s social media accounts.

After: Ran 4 social media accounts with a combined 23,000 followers, posting 5 times a week.

2. Frequency: how often did you do it?

Per day, per shift, per week, per month. Volume work that sounds routine becomes impressive once the reader sees the rate.

Before: Answered customer queries by phone and email.

After: Resolved around 45 customer calls and emails a day, keeping a customer satisfaction score above 90% for 3 consecutive quarters.

3. Time: what got faster, or how quickly did you deliver?

Turnaround times, deadlines met, hours saved, time to hire, time to fix. If you made something faster, give the before and after.

Before: Improved the invoicing process.

After: Automated invoice matching in a spreadsheet, reducing the weekly accounts-payable run from about 6 hours to 2.

4. Money: what did you save, earn, manage or protect?

Budgets you held, revenue you influenced, costs you cut, value of contracts or stock you were trusted with. You do not need to have generated the money; being responsible for it counts as scale.

Before: Organised company events.

After: Planned 9 client events a year on a £40,000 annual budget, coming in under budget each year.

5. People: how many did you lead, train, serve or work with?

Team size, number of people trained, stakeholders, departments, volunteers, children in a class, residents in a care home.

Before: Trained new staff.

After: Trained 22 new starters over 2 years on the till system and food safety procedures; all passed their probation.

6. Rank and comparison: how did you compare?

Top performer, first in the region, selected from a group, above target. These are numbers too.

Before: Consistently exceeded sales targets.

After: Finished in the top 3 of 31 advisers for mortgage applications in 2024, at 128% of annual target.

When nobody measured: honest estimates

Most people have never seen a report on their own work. You can still give a number if you can reason your way to it and would explain the reasoning at interview.

Worked example. You worked on a hotel reception and want to say how many guests you checked in. You never counted. But you know:

• The hotel had 85 rooms and was usually around 80% full.
• Average stay was about 2 nights, so roughly 34 rooms turned over each day.
• You worked 4 shifts a week, and the front desk handled most check-ins during your shift.

That gives about 30 check-ins on a typical shift. Write “around 30 check-ins per shift” or “25 to 35 check-ins per shift”. Both are honest. “31.4 check-ins per shift” is not, because the precision is invented.

Rules for estimates:

• Round. “About 200” rather than “203” when you are estimating.
• Use words that signal estimates: about, around, roughly, up to, more than, over.
• Use ranges when the real number varied: “15 to 20 tickets a day”.
• Be conservative. If your estimate could be anything from 150 to 250, say “more than 150”.
• Keep your working. A note to yourself on how you got each number makes interviews easier.

Watch out: An estimate is not the same as a guess. If you cannot explain where a number came from, leave it out and describe the result in words instead.

Where to find real numbers

Before estimating, check what already exists:

• Performance reviews and appraisals often contain targets and results.
• Old emails and team updates (a “well done, we hit 120 this month” message is a source).
• Job adverts for your own role, which may state team size or budget.
• Public information about your employer: number of sites, students, beds or customers.
• Your own notes, timesheets, rotas and portfolios.
• Colleagues or former managers, who may remember figures you have forgotten.

Respect confidentiality. If a figure is commercially sensitive (exact revenue of a private client, for example), use a percentage, a range or a rounded figure, or describe the scale without the number: “a FTSE 250 client” or “the region’s largest account”.

Percentages or absolute numbers?

Use whichever is more impressive and more honest for the case.

Giving both is often best: “from 5 to 25 sign-ups a week”.

Writing numbers in a CV

• Use digits for numbers in bullets, even under 10 (“3 schools”, not “three schools”). Digits are easier to spot when skimming. This breaks the usual prose style rule, and that is deliberate.
• Use the currency symbol of the job’s country, or say what currency you mean when applying abroad.
• Be consistent: “k” or full numbers, “%” or “per cent”. Pick one.
• Put the number early in the bullet where you can; readers skimming the left edge will catch it.

Do not force it

Not every bullet needs a number. If three of your five bullets have one, the CV already reads as concrete. A bullet with a forced number (“Attended 52 weekly team meetings”) is worse than one without.

The builder flags achievement bullets with no number in them. Treat that flag as a prompt to ask “is there a number here?”, not an instruction to add one to every line.

Tip: For each role, try to find one number for scale (how big) and one for result (what changed). Two good numbers per job is a strong CV.

Next: put your numbers into the achievement bullet pattern, then run the pre-send checklist.
