Ask a home care owner what turnover costs and you usually get a shrug and a number pulled from the air. Ask them what one uncovered case costs and they'll tell you precisely, because they remember the family.
Both numbers are knowable, and the second is usually the larger of the two. Here's how to calculate them for your own agency, using industry figures for the inputs you don't track.
The two bills
Bill one: replacement cost. Every caregiver who leaves has to be found, screened, onboarded and brought up to speed. Published figures put this at $2,600 to $5,000 per caregiver (Enginehire, 2026 staffing and retention report). Annual caregiver turnover was 77% in 2024 (Activated Insights benchmarking; HCAOA recorded a 79.2% peak in 2023).
For a 40-caregiver agency, 77% turnover means replacing about 31 caregivers a year. At the $3,200 midpoint, that's roughly $99,000 annually — before anyone has turned away a single client.
Bill two: revenue never billed. This is the one that doesn't appear in any expense line, because it's not an expense. It's a case you declined. Up to 25% of inbound clients get turned away by agencies with staffing gaps, and 59% of agencies report operating with insufficient staff.
At $30 an hour and 25 billable hours a week, one turned-away client is about $3,250 a month — roughly $39,000 a year. Two a month, sustained, is a six-figure line that never shows up in your books because you never invoiced it.
Why the second bill is invisible and therefore ignored
Replacement cost feels like a cost because money leaves the account: job ads, orientation hours, the supervisor's time. It shows up.
Turned-away revenue never enters the account. There's no line item called "the Alvarez family we couldn't staff in March". The bookkeeping treats it as though it never happened — and the agency treats a staffing shortage as an HR annoyance rather than the revenue event it is.
Reframe it once and decisions change. If you'd told the same owner "someone stole $39,000 from you this year", it would be a crisis. It's the same money.
Do the arithmetic on your own agency
Four inputs:
- Caregivers on staff — the roster, not full-time equivalents
- Annual turnover rate — if you don't track it, start with the 77% industry figure and adjust from what you know
- Cost to replace one caregiver — $3,200 midpoint unless you have a better internal number
- Clients turned away per month — be honest; include the ones where you said "we can start in three weeks" and never heard back
Then:
Replacements per year = caregivers × turnover rate
Replacement cost = replacements × cost per hire
Revenue per lost case = bill rate × weekly hours × 4.33
Lost revenue per year = revenue per lost case × cases turned away per month × 12
Total annual cost = replacement cost + lost revenue
Our turnover cost calculator runs this with the industry medians pre-filled — change any input and watch the total move. It takes about a minute and gives you a number you can hold against every proposed fix.
For a mid-sized private-pay agency the total typically lands somewhere between $150,000 and $300,000 a year. That's the size of the problem. Everything else is a discussion about which lever moves it.
What actually moves the number
Ranked by cost of intervention.
Free: stop losing candidates you already have
The median agency converts about 7.9% of applicants into hires (800 → 195 → 63, home care staffing benchmarks). A meaningful share of the losses are people who were a fit and were gone before anyone called. Answering applications in an hour instead of a day costs nothing and recovers people you already paid to attract. The 28-hour gap covers how to measure yours.
Nearly free: make sure caregivers can see the roles at all
If your careers page doesn't carry JobPosting markup, your open roles cannot appear in Google's job search panel — the box caregivers see when they search "caregiver jobs" in your city. In our August 2026 Houston audit, five of five private-pay agencies had none. The fix is a developer's afternoon, not a budget line. The free visibility check tells you where you stand in 15 seconds.
Cheap, high return: the first three weeks
Turnover clusters early. A caregiver who quits in week three cost the full replacement fee and produced almost no billable hours. Structured contact in weeks one to three — a check-in before the first shift, a call after it, a supervisor visit in week two — has better economics than anything at the top of the funnel and is the stage most agencies leave to chance.
Expensive, sometimes necessary: pay
A raise applies to everyone, immediately, forever, and it's the right answer when you're genuinely below market. But it's the most expensive lever and it's often reached for first. Before spending it, check whether your listings are visible at all — a $1 raise loses to a listing that gets seen, and it's worth knowing which problem you actually have.
What this calculation is not
It isn't a promise of savings, and you should be sceptical of anyone who converts it into one. Nobody controls your local labour market, your pay position, or whether the caregiver you hire on Tuesday likes the client on Thursday.
What the number does is set a scale. When understaffing is costing $180,000 a year, a $997 build and $497 a month is either obviously worth trying or obviously not — and you can make that call in a minute instead of deferring it for another quarter. Our pricing and what it guarantees is public for the same reason: you shouldn't need a sales call to do arithmetic.
The short version
Turnover costs are two bills, not one, and the invisible one is usually bigger. Run your own numbers before you accept another quarter of "hiring is just hard right now" — then work the free levers before the expensive ones.
Frequently Asked Questions
How much does it cost to replace one caregiver?
Published figures put it at $2,600 to $5,000 per caregiver (Enginehire, 2026 staffing and retention report), covering recruiting, screening, onboarding and lost productivity. We use the $3,200 midpoint as a default unless an agency has a better internal number.
What is the average caregiver turnover rate?
77% annually according to Activated Insights' 2024 benchmarking. HCAOA recorded a peak of 79.2% in 2023. At 77%, an agency with 40 caregivers is replacing roughly 31 people a year just to stand still.
How do I calculate what understaffing costs my agency?
Multiply caregivers by turnover rate to get replacements per year, multiply by cost per hire, then add the revenue from cases you turned away: bill rate multiplied by weekly hours multiplied by 4.33, times the number of cases per month, times twelve. Our free calculator does it with industry medians pre-filled.
What is understaffing costing you a year?
Replacement cost of the caregivers who leave, plus the private-pay revenue you never billed because a case went unstaffed. Industry medians pre-filled; change any of them.

A $1 Raise vs a Job Listing That Gets Seen
A dollar an hour across 40 caregivers is about $52,000 a year, permanent and matched by competitors within a quarter. Before spending it, find out whether caregivers can see your roles at all — the test takes 15 seconds.

A case you decline never appears in your accounts. No invoice, no expense, no line item — which is exactly why agencies underestimate what understaffing costs. One turned-away client is about $39,000 a year.
