The Provider Cost of Quality Calculator (PCQC) can help states estimate increased costs and help states “test” financial options to support child care programs. The PCQC is a web-based tool that calculates the cost of care based on site-level provider data. The tool helps users understand the discrete costs of delivering child care services and the projected revenue from family fees, Child Care and Development Fund (CCDF) subsidies, and from Child Care and Adult Food Program (CCAFP) reimbursements for meals and snacks. The PCQC demonstrates if a gap exists between the provider’s cost of producing quality services at a given level and the revenue sources that are available to support service delivery. Knowing the size of the gap at different enrollment levels, quality levels, and various provider types can inform the design of financial support and incentive packages. (author abstract)
