Employee Turnover Cost Calculator
Four inputs, three answers: how many people leave a year, what replacing them costs, and how much a single percentage point of turnover is worth in dollars. The replacement-cost presets come straight from Gallup and the Work Institute, and the table under the calculator shows how far the answer moves between them — which is usually the most useful thing to show a CFO.
Your numbers
Average headcount over the year, not today's number.
Separations in the last 12 months ÷ average headcount. Use voluntary leavers only if you are building a retention case.
Average base salary of the people who leave, not of the whole company, if you have it.
Sourced range: 33% (Work Institute) to 200% (Gallup, managers). Gallup's overall estimate is 50–200% of salary.
7.2% of payroll · $4,680 per employee on the books
Cutting turnover from 18% to 17% keeps 2.5 more people a year.
Same workforce, different replacement-cost assumptions
| Assumption | Cost per leaver | Annual turnover cost | 1-point reduction worth |
|---|---|---|---|
| 33% Work Institute baseline | $21,450 | $965,250 | $53,625 |
| 40% Frontline (Gallup) | $26,000 | $1,170,000 | $65,000 |
| 80% Technical (Gallup) | $52,000 | $2,340,000 | $130,000 |
| 200% Managers (Gallup) | $130,000 | $5,850,000 | $325,000 |
How to use the calculator
- Headcount. Use the average number of employees over the last 12 months. If you hired heavily this year, today's headcount overstates the base and understates your turnover rate.
- Annual turnover rate. Separations in the last 12 months divided by average headcount. If you are building a case for a retention or recognition budget, enter voluntary turnover only — nothing you spend on recognition changes a redundancy or a retirement.
- Average salary. Ideally the average base salary of the people who actually left. Leavers are often paid less than the company average, so the company-wide figure can overstate the cost.
- Replacement cost. Pick the preset that matches who leaves, or type your own. If your leavers are mostly frontline, 33–40% is defensible; for engineers, analysts and specialists, 80%; for managers, 200%.
The result card updates as you type. Copy results puts the inputs and outputs on your clipboard as plain text, ready for an email or a budget deck. Nothing you type leaves your browser.
The formula, step by step
| Output | Formula |
|---|---|
| Leavers per year | headcount × turnover rate |
| Cost per leaver | average salary × replacement cost % |
| Annual turnover cost | leavers per year × cost per leaver |
| Value of a 1-point reduction | (headcount ÷ 100) × cost per leaver |
| Share of payroll | annual turnover cost ÷ (headcount × average salary) |
The last two lines hide a useful shortcut. Because one percentage point of turnover is one percent of your people, a 1-point reduction is always worth 1% of payroll multiplied by the replacement-cost percentage. On a $16.25 million payroll with a 40% replacement cost, that is $162,500 × 0.4 = $65,000 — whatever your current turnover rate happens to be.
Worked example
The calculator opens on this example, so you can check every number against it.
- Headcount 250, annual turnover 18%, average salary $65,000, replacement cost 40% (Gallup's frontline figure).
- Leavers: 250 × 18% = 45 people a year.
- Cost per leaver: $65,000 × 40% = $26,000.
- Annual turnover cost: 45 × $26,000 = $1,170,000 — 7.2% of a $16,250,000 payroll, or $4,680 for every employee on the books.
- One point of turnover: 250 ÷ 100 = 2.5 people × $26,000 = $65,000 a year. Getting from 18% to 17% is worth $65,000; getting to 15% is worth $195,000.
Now change only the assumption. The same 45 leavers cost $965,250 at the Work Institute's one-third baseline, $2,340,000 if they are technical staff at 80%, and $5,850,000 if they are managers at 200%. That six-fold spread is the reason the table under the calculator exists: the replacement-cost percentage moves the answer far more than the turnover rate does.
Where the replacement-cost range comes from
| Preset | Source | What it covers |
|---|---|---|
| 33% | Work Institute | Its standard research estimate is 33.3% of base salary, of which roughly 11 points are direct replacement costs and 22 indirect. |
| 40% | Gallup (2024) | Replacing frontline workers, excluding unmeasured losses in morale and knowledge. |
| 80% | Gallup (2024) | Replacing employees in technical roles. |
| 200% | Gallup (2024) | Replacing leaders and managers. |
Gallup's broader 2019 estimate is that replacing an individual employee costs one-half to two times their annual salary, and it describes even that as conservative. Its own illustration: a 100-person organization paying an average of $50,000 could face turnover and replacement costs of roughly $660,000 to $2.6 million a year. The presets above sit inside that band, apart from the Work Institute's one-third figure, which is the lowest of the four and the easiest number to defend in a skeptical budget review.
Pitfalls that make the number easy to attack
- Mixing monthly and annual rates. The U.S. Bureau of Labor Statistics reports quits as a monthly rate — 1.9% in August 2026. Your HR system almost certainly reports an annual rate. Do not enter a monthly figure here.
- One flat percentage for everyone. If a third of your leavers are managers, run the calculator twice (once for managers at 200%, once for everyone else) and add the results. A blended guess hides where the money actually goes.
- Counting involuntary exits in a retention case. Dismissals, restructures and retirements are real costs, but no recognition or rewards budget prevents them. Including them makes the business case look bigger and then fall apart in review.
- Treating the result as cash you will get back. Most replacement cost is lost time and productivity, not invoices. It is real money, but it shows up as slower delivery and overtime rather than a line you can cut from the budget.
Frequently asked questions
How do I calculate the cost of employee turnover?
Multiply your headcount by your annual turnover rate to get leavers per year, multiply your average salary by a replacement-cost percentage to get the cost per leaver, then multiply the two. With 250 employees, 18% turnover, a $65,000 salary and a 40% replacement cost, that is 45 leavers at $26,000 each, or $1,170,000 a year.
What replacement-cost percentage should I use?
Use the role mix of the people who leave. Gallup estimates roughly 40% of salary for frontline workers, 80% for technical roles and 200% for leaders and managers; the Work Institute uses 33.3% of base salary as its standard estimate. If you have to pick one number for a finance review, the lower end is the easiest to defend.
Is a 1-point turnover reduction realistic?
For most companies, one point is a small change — at 250 employees it means keeping 2.5 more people a year. That is why the calculator reports it: it gives you a concrete dollar value to compare against the cost of a retention initiative, without having to promise a large reduction.
Should I use total turnover or voluntary turnover?
Use total turnover to size the overall cost of churn. Use voluntary turnover when you are justifying spend on recognition, rewards or engagement, because those programs only influence people who choose to leave.
Does this calculator store my data?
No. The arithmetic runs entirely in your browser and nothing you enter is sent anywhere or saved.
