Care Home Staffing Calculator: Work Out Safe Staffing Levels (2026)
A care home staffing calculator you can run by hand: grade resident dependency, turn care hours into staff per shift, and keep the evidence CQC expects. Includes a 40 bed worked example.

Short answer: There is no fixed legal staffing ratio for a care home. CQC expects "sufficient numbers of suitably qualified staff" for the needs of the people you support, and you need to show how you decided. A dependency based calculation does that: grade each resident, convert their care needs into hours, split the hours by shift and divide by shift length. The method below takes about ten minutes for a small home.
Too Few Staff = CQC Problems
What happens with understaffing:
- Unsafe care
- CQC enforcement
- Staff burnout
- More incidents
CQC requires "sufficient numbers of suitably qualified staff." You must prove it.
Care Home Dependency Calculator: Grade Your Residents First
A dependency calculator starts with a grade for each resident, not with a headcount. Grade everyone against the same written criteria, and record who graded them and when.
| Level | Care Hours per Day | Examples |
|---|---|---|
| Low | 2 to 3 hours | Mostly independent |
| Medium | 3 to 4 hours | Needs some help |
| High | 5 to 6 hours | Significant help needed |
| Intensive | 7 to 8 hours | Complex health needs |
The hours in this table are planning figures for the worked example on this page. They are not CQC requirements, and your own assessment of each person's needs should replace them where it differs.
Regrade when a resident's needs change, after a hospital stay, a fall or a change in medication, and at least monthly for the whole home.
Basic Staffing Ratios
These ratios are illustrations to sense check your result. They are not a legal minimum.
Residential Care (Day Shift)
| Dependency | Staff Ratio |
|---|---|
| Low | 1 staff per 8 to 10 residents |
| High | 1 staff per 3 to 5 residents |
Night Shift
| Dependency | Staff Ratio |
|---|---|
| Low | 1 staff per 15 to 20 residents |
| High | 1 staff per 7 to 10 residents |
Nursing homes: Add at least one registered nurse per shift.
Care Home Staffing Calculator: Step by Step
Step 1: Total Care Hours
| Resident Group | Calculation |
|---|---|
| Low dependency | Number × 2.5 hours |
| Medium dependency | Number × 3.5 hours |
| High dependency | Number × 5.5 hours |
| Intensive | Number × 7.5 hours |
Add them all for total daily care hours.
Step 2: Split by Shift
| Shift | % of Total |
|---|---|
| Day | 45% |
| Evening | 35% |
| Night | 20% |
Step 3: Convert to Staff
Divide hours by shift length (usually 8 hours).
Add 15 to 20% for handovers, breaks, documentation.
Always round up.
Example: 40 Bed Home
Residents: 12 low, 18 medium, 8 high, 2 intensive
Total care hours: 30 + 63 + 44 + 15 = 152 hours/day
Day shift: 152 × 0.45 ÷ 8 = 8.5 → Round to 10 staff (with buffer)
Night shift: 152 × 0.20 ÷ 8 = 4 → Round to 5 staff (with buffer)
Dementia Care Home Staffing Levels
Dementia care has no separate legal ratio either. What changes is the dependency grade. Residents living with dementia often need more supervision, more prompting and more support at night than their physical needs suggest, so grade for those needs and not only for personal care tasks. Where residents wander, wake at night or become distressed, record that in the assessment and show how your night and evening numbers respond to it.
FAQs
What is the legal minimum staffing in a care home?
There is no fixed legal ratio. CQC requires "sufficient numbers of suitably qualified staff" based on resident needs. You must assess dependency and justify your staffing levels.
How do you use a care home staffing calculator?
Grade each resident by dependency, multiply the number of residents at each grade by the care hours for that grade, split the total across day, evening and night, then divide by shift length and add a buffer for handovers and breaks. Round up and record the result.
What is a care home dependency calculator?
It is a method for grading how much support each resident needs and turning those grades into care hours and staff numbers. The grades must come from your own assessment of each person, and the result should be reviewed when needs change.
How often should you review staffing levels?
Monthly at minimum, and after any significant change in resident needs. Document your assessment method and reasoning for CQC.
Do you count the manager in staffing ratios?
Only if they are providing direct care. Supernumerary managers should not be counted in care delivery ratios.
What about agency staff in ratios?
Agency staff count towards ratios but CQC may question over reliance on agency workers. Track permanent vs agency ratios.
Warning Signs of Understaffing
- Call bells ringing for a long time
- Residents left in soiled clothing
- Staff working through breaks
- Increase in falls and incidents
If you see these, review staffing immediately.
