Vacancy rate is one of the quietest indicators on the HR dashboard and often one of the most informative. When the number climbs, it usually tells a story about either what's happening on the recruiting side (demand outstripping capacity, pay lagging the market, slow time-to-fill) or what's happening on the retention side (attrition rising faster than replacements can be hired). The aggregate number hides most of that story, which is why good workforce planning teams watch vacancy rate by segment, by role type, by level, and over time. The teams that can tell the difference between a vacancy spike driven by hiring slowness and one driven by unexpected attrition have an easier time deciding what to fix.
How to Calculate a Vacancy Rate The standard formula: open positions divided by total budgeted positions, multiplied by 100. If a company has 500 budgeted roles and 35 are currently open, the vacancy rate is 7%.
Be consistent about what counts. Some companies include requisitions that have been approved but not posted; others count only actively recruited positions. Some exclude contractor roles; others include them. Whatever definition you use, apply it consistently across periods so trend analysis holds up.
What a Healthy Vacancy Rate Looks Like For most knowledge-work companies, a vacancy rate of 3 to 7% reflects normal operations: some roles always in flight, some requisitions freshly posted, some in late-stage interviewing. Below 3% may indicate underinvestment in growth; above 10% usually signals a problem.
Industry matters. Healthcare in 2023 through 2025 frequently ran vacancy rates of 15 to 20% in nursing, driven by well-documented structural shortages. Tech during the 2022 correction ran near-zero vacancy as hiring froze. Manufacturing during the same period ran 8 to 12% driven by labor market tightness.
Should Leaves of Absence Count Toward Vacancy Rate? Usually no. Employees on FMLA, parental leave, or short-term disability still hold their roles; the position isn't vacant. Some teams track backfill coverage separately if leaves are creating coverage gaps.
Common Drivers of High Vacancy Rates Recruiting capacity: too few recruiters, too many open requisitions, or inefficient interview processes that slow time-to-fill. A recruiting team without adequate capacity creates a vacancy rate that rises mechanically as requisitions pile up.
Compensation gaps: pay that lags the market means offers get declined and current employees leave. Offers declined because of pay show up directly in vacancy rate.
Unusual attrition: a spike in turnover (planned or unplanned) opens roles faster than recruiting can fill them. This is often the explanation when vacancy rate climbs alongside a rising turnover rate.
Hiring freezes that don't fully cancel requisitions: the vacancy rate looks high because requisitions stay on the books even though recruiting isn't active.
Reducing Vacancy Rate Through Better Workforce Planning Segment the vacancy rate by team, level, and role type. The aggregate rate may mask a few segments doing the heavy lifting (high tech engineering, senior sales) while others are healthy.
Pair vacancy rate with time-to-fill, offer-acceptance rate, and employee retention analysis so the root cause is visible. Coordinate with compensation benchmarking and onboarding workflow reviews to address the upstream drivers. Reference the BLS JOLTS monthly release for current job openings rates (the macro equivalent of vacancy rate) and the BLS Employment Projections for industry-level outlook data.
