What this calculator estimates
This build-cost calculator is designed for planning-level budgeting for a backyard pickleball court pad and common add-ons. It converts your dimensions and unit prices into a line-item estimate so you can compare quotes and see which choices drive the total.
- Pad area (playing area plus your buffer/runout) priced by base prep and surface finish cost per square foot
- Fence priced by perimeter feet (posts, fabric/netting, and gates are typically bundled in “$/ft” quotes)
- Lighting and net/posts as flat allowances
- Labor multiplier and contingency applied as percentage adders to the subtotal (see “Assumptions & limitations” for how these are typically interpreted)
You can set any line item to 0 to model a minimal build (e.g., no fence, no lights) or to reflect items you already own.
Measurements: playing area vs. total pad (buffer)
A regulation pickleball playing court is 44 ft by 20 ft. Most homeowners build a larger structural pad so players have space to stop, pivot, and retrieve balls without hitting landscaping or fencing. In this tool, that extra space is captured by Perimeter buffer each side (ft).
Example: If you enter a 5 ft buffer, the pad grows by 10 ft in each direction (5 ft on both sides). This buffer is applied to both length and width to compute the pad size used for base and surface costs.
Formulas used (with definitions)
The calculator follows a straightforward geometry + unit-cost model.
1) Total pad dimensions
- L = playing length (ft)
- W = playing width (ft)
- B = buffer each side (ft)
Total pad length = L + 2B
Total pad width = W + 2B
2) Pad area
Area (square feet):
3) Fence perimeter
Perimeter (linear feet) for a rectangular pad:
P = 2[(L + 2B) + (W + 2B)]
4) Line-item costs
- Base prep cost = A × baseCost ($/sq ft)
- Surface finish cost = A × surfaceCost ($/sq ft)
- Fence cost = P × fenceCost ($/ft)
- Lighting allowance = lighting ($)
- Net/posts allowance = netCost ($)
5) Labor and contingency adders
These are percentage-based adders applied to your pre-adder subtotal. A common planning approach is:
- Subtotal = base + surface + fence + lighting + net
- Labor = Subtotal × (labor% ÷ 100)
- Contingency = (Subtotal + Labor) × (contingency% ÷ 100)
- Total = Subtotal + Labor + Contingency
If your contractor quotes labor differently (e.g., labor already included in $/sq ft pricing), set the labor multiplier to 0 or adjust unit costs to match your quote structure.
Interpreting your results
The most useful way to read the output is as a decision dashboard:
- Total pad area drives the base + surface portion of the budget. Small buffer changes can noticeably change cost because they change area (a squared effect).
- Perimeter drives fence costs. If fencing looks high, verify whether your $/ft quote includes gates, corner posts, and footings.
- Lighting and net are “fixed” allowances—great for modeling phases (build pad now, add lights later).
- Labor + contingency help bridge the gap between materials pricing and real-world installed pricing, unknowns, and change orders.
Planning tip: If you’re collecting bids, plug each contractor’s assumptions into the same inputs so you can compare apples-to-apples (especially buffer, fence scope, and what’s included in “$/sq ft”).
Worked example (using common default-style inputs)
Assume:
- L = 44 ft, W = 20 ft
- B = 5 ft buffer each side
- baseCost = $4.50/sq ft, surfaceCost = $6.25/sq ft
- fenceCost = $32/ft
- lighting = $4,500, netCost = $420
- labor = 18%, contingency = 12%
Step 1: Pad dimensions
Total length = 44 + 2×5 = 54 ft
Total width = 20 + 2×5 = 30 ft
Step 2: Area
A = 54 × 30 = 1,620 sq ft
Step 3: Perimeter
P = 2(54 + 30) = 168 ft
Step 4: Costs
- Base = 1,620 × 4.50 = $7,290
- Surface = 1,620 × 6.25 = $10,125
- Fence = 168 × 32 = $5,376
- Lighting = $4,500
- Net/posts = $420
Subtotal = 7,290 + 10,125 + 5,376 + 4,500 + 420 = $27,711
Labor (18%) = 27,711 × 0.18 = $4,988
Contingency (12%) = (27,711 + 4,988) × 0.12 = $3,923
Estimated total ≈ 27,711 + 4,988 + 3,923 = $36,622
From this breakdown you can see the pad area (base + surface) dominates, while fence and lighting are meaningful secondary drivers.
Comparison: how choices affect cost
Use a table like the one below as a quick “what-if” guide when you’re deciding scope. Exact numbers depend on your inputs, but the cost drivers are consistent.
| Choice |
What changes in the model |
Typical budget impact |
| Increase buffer/runout |
Raises area (A) and perimeter (P) |
Often the biggest swing because base + surface scale with square footage |
| Add or upgrade fencing |
Raises fenceCost × perimeter |
Moderate to high; depends on height, gates, wind screens, and footings |
| Add lighting |
Adds a fixed allowance |
Moderate; may become high if trenching, new panel capacity, or permitting is needed |
| Higher surface system |
Raises surfaceCost ($/sq ft) |
Moderate; coatings/cushion systems can materially change price |
| Higher labor/GC involvement |
Raises labor multiplier |
Can be significant; especially where access is tight or scheduling is complex |
Assumptions & limitations (read before using as a “quote”)
- Planning estimate only: Outputs are budgeting guidance, not a binding bid. Local pricing, access, and soil conditions can change costs materially.
- Rectangular pad assumption: The model assumes a simple rectangle. Irregular shapes, angled corners, or separate apron areas aren’t represented.
- Unit-cost inputs must match scope: “$/sq ft” may or may not include labor, reinforcement, saw cuts, color coats, striping, crack repair, etc. Adjust inputs to match your quote.
- Labor multiplier meaning: This tool treats the labor percentage as an adder on the subtotal of line items. If labor is already baked into your $/sq ft and $/ft prices, set labor to 0 to avoid double counting.
- Contingency usage: Contingency is modeled as an additional percentage to cover unknowns. It is not a substitute for engineered drainage or geotechnical guidance where needed.
- Common exclusions: permits/HOA approvals, demolition and haul-off, extensive grading, retaining walls, significant drainage structures, electrical trenching distance beyond a standard allowance, panel upgrades, landscaping restoration, and ongoing maintenance.
- Regional variability: Material and labor rates vary by region and season. Update your unit costs with recent local quotes for best results.
Practical tips for getting more accurate numbers
- Ask contractors to break out: base/grading, slab/asphalt, coatings/striping, fence (including gates), and electrical/lighting.
- Confirm whether fencing quotes are per-foot installed and what height and fabric type they assume.
- If you’re unsure on buffer size, start conservative, then run a second scenario with more runout to see the cost difference.
- Use the CSV export to save scenarios (e.g., “No lights,” “Premium surface,” “Full fence”).
