Playground Budget Calculator

This calculator estimates a licensed childcare playground's build-out cost across three components: equipment, safety surfacing, and installation. Equipment Cost scales with Playground Capacity (the number of children using the space at once) times a per-child rate that steps up with Age Group -- $800 for toddler equipment (simpler, lower structures), $1,200 for preschool (moderate complexity), and $1,500 for school-age (larger, more complex climbing structures). Surfacing Cost assumes 100 square feet of surfaced area per child of capacity -- an intentionally conservative figure, taken from the 75 square feet per child of total outdoor play area that Caring for Our Children and most state childcare licensing rules require, rounded up to absorb the six-foot equipment use zone ASTM F1487 and the CPSC handbook require around stationary equipment. On a real site only the equipment use zones need protective surfacing, so this line will usually come in above a surfacing bid drawn from an actual site plan. That area is priced per square foot by Surface type -- poured-in-place rubber at $12/sq ft (the safest and most expensive option, with the lowest long-term maintenance), engineered wood mulch at $3/sq ft, and pea gravel at $2/sq ft (cheapest, but requires the most ongoing top-off maintenance and offers less fall protection than rubber). Two constraints this cost model does not price in but that will decide the choice for a licensed facility: the CPSC Public Playground Safety Handbook advises against loose-fill surfacing entirely on playgrounds intended for toddlers or any children who put objects in their mouths, which effectively rules out both the mulch and gravel options for a toddler yard; and pea gravel at the CPSC's 12-inch installed depth protects only to a 5-foot critical fall height (versus 7 feet for wood mulch and 10 feet for wood chips or rubber mulch), so it caps how tall the equipment over it can be. Loose-fill materials also frequently fail the ASTM F1951 firmness and stability test that ADA/ABA accessible routes require, so budgeting pea gravel across a whole play area may mean budgeting a separate accessible surface as well.

These three surfacing rates are installed prices, not material-only, and each is a single point estimate near the low end of a real range: published poured-in-place installations run about $12-18 per square foot for basic single-colour work and $20-30 for customised designs, before $3-6 per square foot of aggregate base preparation on a site that needs it. The 30% Installation Cost line covers equipment installation only -- surfacing installation is already inside the per-square-foot rate. Installation Cost is modeled as a flat 30% of Equipment Cost, within the 25-40% range installation typically runs as a share of equipment spend on commercial playground projects. Total Cost is the sum of all three. Playground Capacity is the single biggest lever on Total Cost overall, since it scales all three cost components at once across its full 1-200 child range. Between the two category choices, Surface swings Total Cost slightly more than Age Group does, but by much less than the raw price ranges suggest: the full surfacing swing is $1,000 per child of capacity and the full age-group swing is $910 per child once the 30% installation riding on equipment is counted -- about a 10% edge, not the 6-to-1 edge the $12-versus-$2 per-square-foot spread implies.
