About this calculator

Extended-care and before/after-school programs are often priced as an add-on convenience without anyone checking whether the hourly staffing cost actually clears the revenue collected. This calculator takes children enrolled in extended care, the ratio required during that time block (often the same or looser than core hours), staff hourly pay, hours the program runs per day, and the price charged per child, then computes daily and monthly margin. Because extended care runs shorter blocks than the main program day, staffing often can't be trimmed proportionally — a 90-minute after-school block still needs a full staff member for the full ratio, so cost per child-hour tends to run higher than core-day cost per child-hour. This tool isolates that block so you can see whether it's a genuine profit center or a convenience loss-leader, and by how much.

FormulaStaff needed = CEILING(children ÷ ratio); daily labor cost = staff × hourly pay × hours; daily revenue = children × price per child; margin = daily revenue − daily labor cost.

Worked example

Using the values the calculator loads with:

Inputs

Children enrolled in extended care: 22
Required ratio during this block: 12
Staff hourly pay (loaded): 19 $/hr
Program length: 2 hrs
Price charged per child per day: 18 $
Days offered per month: 21

Results

Monthly program margin: $6,720
Daily margin: $320
Margin per child / day: $14.55
Staff required this block: 2
Daily labor cost: $76

What each field means

Inputs

Children enrolled in extended care: The children enrolled in extended care used in the calculation. Starts at 22 so you have a working example on load.
Required ratio during this block: The required ratio during this block used in the calculation. Starts at 12 so you have a working example on load.
Staff hourly pay (loaded) ($/hr): The staff hourly pay (loaded) used in the calculation, measured in $/hr. Starts at 19 $/hr so you have a working example on load.
Program length (hrs): The program length used in the calculation, measured in hrs. Starts at 2 hrs so you have a working example on load.
Price charged per child per day ($): The price charged per child per day used in the calculation, measured in $. Starts at 18 $ so you have a working example on load.
Days offered per month: The days offered per month used in the calculation. Starts at 21 so you have a working example on load.

FAQ

Why does a short program block cost so much per child?

Staffing snaps to whole people regardless of block length, so a 90-minute program needing 2 staff for ratio compliance pays for 2 full hourly blocks (often with a minimum-shift-length rule) no matter how short the program itself runs. Short, low-enrollment blocks are the most likely part of your schedule to run at a loss even when the main program day is healthy.

Should extended care be priced to fully cover its own labor?

Many operators intentionally accept a smaller margin (or break-even) on extended care because it's a strong retention and enrollment tool for working parents who need coverage past the core day. That's a reasonable strategy, but you should choose it deliberately after seeing the real numbers, not by accident because no one ever ran this math.

How do I improve margin without raising price a lot?

Combine age groups where licensing allows a looser ratio for the extended-care block specifically, since many states allow different (looser) ratios outside core instructional hours. Also check whether enrollment is clustered enough to run one larger group instead of splitting into two under-filled rooms each needing their own staff.

Does this account for staff who are already on shift for other reasons?

No — it assumes dedicated extended-care staffing. If you're using teachers already on a closing shift who'd be paid regardless, the marginal cost of extended care is lower than modeled here; adjust the hourly pay input down to reflect only the incremental cost if that's your situation.

Accuracy and limitations

Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
