Playground Equipment Budget Calculator

Estimate total playground project cost including equipment, installation, site prep, surfacing, and shade based on age group and child capacity.

About this calculator

Age Group sets a base equipment cost per structure ($18k Toddler up to $120k All-Ages Inclusive) AND, separately, how many kids that base structure is assumed to already cover (10 for Toddler up to 25 for All-Ages Inclusive) -- so raising Child Capacity above that baseline triggers a Capacity Upcharge priced per extra kid at a rate that ALSO climbs with Age Group ($1,500/kid for Toddler up to $3,000/kid for All-Ages Inclusive). The two effects compound: an all-ages-inclusive playground both starts from a pricier base structure and charges more per child once you exceed its (admittedly higher) built-in capacity. Number of Play Structures multiplies the base equipment cost directly, but it also raises the capacity threshold before any upcharge kicks in (baseCapacity x numStructures), so adding a second structure both increases cost on its own AND buys headroom that can absorb more Child Capacity before the per-kid upcharge applies at all.

Site Preparation ($) and Surfacing Cost ($) are driven purely by Estimated Play Area (sq ft), itself a flat 75 sq ft per child of capacity -- neither line depends on Age Group, Equipment Style, or Number of Play Structures even though those three drive most of the rest of the budget. Include Swings? sizes its own bay count directly from Child Capacity (roughly one bay per 8 kids) independent of Age Group or structure count, which is why swing cost can be a larger or smaller share of the total depending on how capacity compares to the number of structures you specified.

  1. Identify Input Parameters
    4 parameters
    Age group = 1, Child capacity = 30, Number of play structures = 1, Equipment style = 0 = 6 input(s) provided
  2. Calculate Equipment cost
    Equipment cost
    84000 = $84,000
  3. Calculate Total project cost
    Total project cost
    129750 = $129,750
  4. Calculate Installation cost
    Installation cost
    21000 = $21,000
  5. Calculate Site preparation
    Site preparation
    18000 = $18,000

Frequently Asked Questions

Why does the same Child Capacity cost more on an All-Ages Inclusive playground than a Toddler one?

Two compounding reasons. First, All-Ages Inclusive starts from a $120,000 base structure cost versus Toddler's $18,000. Second, All-Ages Inclusive's base structure is assumed to already cover 25 kids (versus Toddler's 10), but any capacity ABOVE that base is charged at $3,000 per extra kid for All-Ages Inclusive versus $1,500 for Toddler -- so even the capacity upcharge itself is pricier per child on the more elaborate age group, on top of the higher starting base.

Does adding a second play structure just double the equipment cost?

Not quite -- it does more than double the base cost's inputs, but the outcome depends on Child Capacity. Number of Play Structures multiplies the base equipment cost directly (2 structures = 2x base cost), but it ALSO doubles the "included" capacity before any per-kid upcharge applies. If your Child Capacity already fit within one structure's baseline, adding a second structure you don't need for capacity still adds its full base cost -- the capacity upcharge simply drops to $0 either way.

Why doesn't Equipment Style affect Site Preparation ($) or Surfacing Cost ($)?

Because those two lines are sized from Estimated Play Area (sq ft) alone -- a flat 75 sq ft per child of Child Capacity -- which has nothing to do with what the equipment looks like. Equipment Style's 15%-40% multiplier only applies to the equipment subtotal (base cost plus any capacity upcharge), which is why choosing Custom/Themed over Basic raises Equipment Cost ($) and, through the 25% installation rate, Installation Cost ($) too, but leaves Site Preparation ($) and Surfacing Cost ($) untouched.

How is the swing bay count calculated?

Swing Bays is sized directly from Child Capacity at roughly one bay per 8 kids (rounded up, minimum 1 bay when swings are included at all), independent of Age Group, Number of Play Structures, or Equipment Style. That's a deliberate simplification: a swing set's capacity is about how many kids can use it at once, which scales with total playground capacity rather than with how many climbing structures are on site.
