How to put numbers on a résumé without inventing them

Numbers make a résumé line specific. Here is where honest figures come from, what the check here counts as measurable, and what to write when nothing was ever measured.

— an invented number is a bad trade.

A number turns a claim into a fact a reader can weigh. "Reduced database cost by thirty-one per cent by moving cold ledger rows to partitioned storage" says what happened, how much it mattered and how it was done. The version without the figure says only that something improved, which is what everybody writes.

Where honest numbers come from

Look at four places before you decide you have none. Dashboards and reports you saw at the time. Tickets, releases and commit history with dates attached. The review documents your manager wrote about the work. The people who were there, who often remember the figure you forgot. A number reconstructed from a real source is a number you can defend.

What counts as measurable

Money, percentages, multipliers, durations, volumes and counts with a unit attached. Time saved and error rates are the two most under-used, because almost all operational work moves one or the other. If a process took forty minutes and now takes six, that is the line.

When nothing was ever measured

Plenty of good work leaves no figure behind. Write the scope instead. The number of people you supported, the number of sites, the size of the budget you worked inside, the number of cases a week, the length of the period you covered alone. Scope is a number, it is usually one you know, and it answers the reader's real question, which is how big the job was.

The other honest move is to say what became possible. "Wrote the on-call runbook the team still uses" has no percentage in it and tells a reader something true about how the work outlasted you.

What the check counts

The ATS checker tests each experience line for a figure with a unit: a percentage, an amount of money, a multiplier, or a count followed by a word such as users, customers, hours, months, engineers, reports or markets. Two or more matching lines earn the full twenty-five points of the measurable-evidence rule, one earns twelve. The report names the lines it found, so you can see whether your best evidence was written in a form it could read.

A bare number with no unit often goes unrecognised. "Handled 40 daily" is ambiguous to a parser and to a person. "Handled forty claims a day" is neither.

The trade nobody should take

An invented figure costs more than it earns. It survives one reading and fails the first question about how it was calculated, and by then the interview is about your honesty rather than your work. There is no version of this trade that pays. Where you are unsure, write the smaller claim you can prove.

Writing them into the document

Open the role in the résumé builder and edit the line in place. The page beside the editor redraws as you type, which matters here because a figure often pushes a line onto a second row, and a section that reads well in a text box can look crowded on paper. Keep the figure early in the sentence where it is scanned rather than hunted for.

When the section is done, run the check and look at the content rows. Two measurable lines, three action-led lines and five achievement lines in total is the shape the rules reward, and it is also, by coincidence rather than design, roughly what a human reader can absorb before moving to the next page. The summary goes on top of it afterwards.

Numbers by field

• Operations and support. Cases or tickets a week, response and resolution times, backlog cleared, sites or shifts covered.
• Engineering. Latency, error rate, cost, deployment frequency, services owned, volume served.
• Sales and account work. Revenue, renewal rate, pipeline, accounts held, territory size, quota against attainment.
• Teaching and care. Class or caseload size, pass rates, hours of cover, programmes run, people trained.
• Research and analysis. Sample sizes, datasets, publications, studies run, decisions the work informed.

Confidential figures can be given as a proportion rather than an absolute. "Cut regional churn by a fifth" says enough without publishing a number you are not free to publish, and it is accurate.

Where a figure should sit in the sentence

Early. A reader scanning down a page sees the first half of each line, so a result buried at the end is a result they may never reach. Put the change near the front and the cause behind it: "Cut checkout errors by forty-six per cent after tracing a race condition" rather than the same clause arranged the other way round. Both are true, and only one of them survives a ten-second scan.
