How to write resume bullet points with numbers, even when you don't have the numbers

The formula

Action verb + what you did + the tool or method + the measured result. Not every bullet needs every part, but your top three bullets in each role should have all four.

• Weak: "Responsible for customer onboarding."
• Strong: "Redesigned customer onboarding in HubSpot, cutting time-to-first-value from 14 to 5 days and lifting 90-day retention 11 points."

Action verbs that carry weight

Led, built, designed, launched, negotiated, reduced, grew, automated, migrated, delivered, owned. Avoid "responsible for", "helped with", "involved in", "assisted"; they describe proximity to work, not work.

Finding numbers you didn't think you had

• Scale: how many users, customers, transactions, tickets, pages, components, sites, employees.
• Money: revenue influenced, costs saved, budget managed, deal sizes, prices changed.
• Time: hours saved per week, cycle time reduced, deadlines beaten, time-to-hire.
• Quality: error rates, defects, uptime, satisfaction scores, audit results.
• Frequency: reports per month, releases per week, calls per day.
• Rank and comparison: top 10% of team, first to ship, fastest in region.

When you truly can't disclose figures

Use percentages and ratios instead of totals ("cut CAC 31%"), ranges ("$5–10M budget"), or labelled estimates ("~2,000 monthly users"). An honest approximation beats no number.

Before and after, across roles

• Nurse: "Provided patient care" → "Cared for 5–6 med-surg patients per shift and led a fall-prevention huddle that cut unit falls 40%."
• Teacher: "Taught mathematics" → "Taught mathematics to 120 students a year across 4 grades; raised pass rates from 71% to 88% over two years."
• Accountant: "Prepared month-end reports" → "Closed month-end for 3 entities in 4 days (from 7) after automating 15 reconciliations in Excel."
• Developer: "Fixed bugs" → "Cut production incidents 45% by adding integration tests and alerting to 6 services."

Keep it readable

One idea per bullet, under two lines, no filler. Three to five bullets per recent role, fewer for older ones. The number goes near the end where the eye lands.
